How to install Roll roofing

2011-10-08T07:46:00.000-07:00

Roll roofing is the easiest roofing material to install on your own. Roll roofing is nothing but roofing sheets that are manufactured in rolls. The rolls are installed as overlapping stripes. Durability of about 5 to 10 years, makes roll roofing a popular roofing material. Roll roofing sheets are available in a wide range of materials, but the mostly used ones are made of asphalt, coated with felt or fiberglass. Basically the combination of its contents depend upon the requirements of its user. Changes are made in the composites of the roll roofing sheets, to enhance some unique qualities such as adhesion, slip resistance, water absorption, tear resistance and remarkable flexibility.

Roll roofing sheets are mostly used on the slightly sloping roofs of garages, additional porches or as a shed. If you want to finish the home construction on your own, then roll roofing is the best option for the conventional roofing shingles that you have.The most important thing to consider, is the climate on the day of the roll roofing installation. It must be sunny and not quite cold because the coldness will make the roofing unannealed and stiff. The roll sheet must be exposed to the sun for a whole of 24 hours before the actual installation process. This becomes necessary in order to make the rolls flat.

Roll Roofing

There are two installation methods, namely the hot asphalt method and the cold asphalt method. Where the hot asphalt method is a bit conventional, the cold asphalt method is the really popular one. In the cold asphalt method, the spreadable adhesive is smoothed on the roof top initially and then the roll roofing is installed over it. Roll roofing can be installed using a simple adhesive and even without using any nails. Before installation, make sure that the roof top is totally clean and dried up.

We haven't gotten around to discussing the kind of roofing that one must select. The type of roofing depends on the individual person's requirements. To aid in your choice, I provide you with information on the various roll roofing types available in the market

Types of Roll Roofing

- Eaves flashing roofing - This is a polymer modified bituminous roofing roll, that works as a self adhesive. It is specially designed for pooling water or as a ice developing area.

- Smooth surface roll roofing - This roofing consists of ground talc or mica, designed as a flashing for the extrusions and overlapping of the seals. It is specifically used for the roof's overhanging, valleys and also as an extra sealant on almost every kind of roof.

- Mineral surfaced roll roofing - The surface of this roofing consists of mineral granules and small rocks. It is most commonly used for small structures like storage buildings, barns and extensive sheds.

- Saturated felt roofing - This an organic based asphalt roll roofing, underlaid between the roofing material and the roof deck.

The invention of metal has been essentially the most conclusive change in the entire human past. Metal importance could be judged that it is being used every where in the routine life for example in land automobiles, kitchen accessories and various other house hold objects and almost in every industry all through the world.. Metal forming is also getting popularity day by day. There are different sorts of metal forming and out of those varieties Roll Forming is a very utile, helpful and multi purpose method.

Roll Forming Machine

Roll forming is a communal and utile method for composing things from sheet metal and it contains an interesting process .Some peculiar sort of machine is used for roll form metal. There are numerous rolls in roll form machines which are adjusted side by side or one following the other that are separated into different sets that are also known as 'stands'. These stands don't bring huge changes into the metal.

Roll form machines crook the metal into preset shapes. There are some requirements mean each and every shape require its personal and alone set of rollers. It's obvious from this point that one roll form machine can form or prepared one shape only. This type of roll forming machines is made for industrial or trade use.

There's another roll forming machine which definitely has automatic process with out breaking metal and takes less time. Though it has many advantages but its rates are also very high. These machines contains different qualities and steel roofs, steel, walls, studs, all of them are the production of roll form machines. Many federations supply roll form solutions to the building enterprises and fulfill the fundamental requirements of the market.

After the great invention of new forming procedures there are numerous companies which are offering services for roll- forming and they have quite experienced staff that design and produce new ways of applications that are taking place of old and previous manufacture. The designers also keep in minds the value of new product along with its affordable cost. In the roll forming process and manufacturing, lots of time is consumed for in its final or finishing steps.

Sheet Metal Forming Tools

2011-09-19T20:06:00.000-07:00

Sheet metal forming used to be done by hand. That was previously the job of strong, skilled, handy blacksmiths who relied on a hammer and a hot oven to get metal to a desired format. Nowadays there are various sheet metal forming tools that are used to achieve the perfect shape for the metal pieces that are used in many types of building applications.

Wheeling Machines

Wheeling Machines

The Wheeling Machine, also called an English Wheel, is a popular type of metal forming tool that is used to create double curves in metal. The user puts a flat metal sheet (usually aluminum or mild steel) through this C-shaped machine to get even curves. These machines are usually used for the curving elements of cars, boats, and other complicated machinery. The Wheeling Machine stretches and thins the metal before forming it into the desired shape. These metal forming tools are for serious industrial projects, and the estimated cost for a Wheeling Machine is anywhere between $3,000 to $5,000.

Air Power Hammers

Air Power Hammers

An air power hammer is a tool that has replaced the need to use a handheld hammer for blacksmithing projects. This metal forming tool uses a powerful force to bend even the toughest metals into desired shapes. This tool shapes and planishes metal. Shaping is done by modifying the condition of the metal (such as stretching it out first) and then turning it into another form. When something is "planished" it is being reshaped from light hammer force. You can find an Air Power Hammer for between $2,000 to $5,000.

Shrinker Stretcher

Shrinker Stretcher

Another metal forming tool is the Shrinker Stretcher tool. These machines are built to stretch or shrink various types of metal, usually mild steel. A special adapter, called a "jaw" is required fo this type of machine. The Shrinker Stretcher is air-powered and easily switched from a shrinking setting to a stretching setting with a simple change of the jaw. Shrinker Stretchers go for up to $10,000 (possibly more depending on the manufacturer).

Bead Forming Machines

Bead Forming Machines

Uniform beads are small circular pieces of metal that have been smoothed around the edges. Metal beads could be used for jewelry or as components in major machinery; think of an assembly line that requires constant movement on wheels. The beads are formed when the two interlocking pieces slide against each other continuously. Depending on where you find them, you will probably pay a few hundred dollars for these metal forming tools.

Why Do We Need Metal Forming Tools?
Metal forming tools are important for any project that involves metal. You certainly can't bend or form a heavy duty steel plate to tight requirements by hand; you need a machine that is powered by more than just elbow grease. Common businesses that need metal shaping tools include car production plants, airplane manufacturers, and small businesses that deal in iron works and metal fencing

Function Of Roll Forming Machine And Roll Forming Machine Firm

2011-09-12T21:32:00.000-07:00

Time is passing swiftly and man is getting progress in almost all fields of life. Now the present shape of this earth is totally completely different from the earliest time world.

Roll Forming For Roofing Components

2011-09-08T03:15:00.000-07:00

Roll forming of roofing components for the pre-engineered building and component industries presents unique challenges for manufacturers. Tighter profile tolerances, wider product ranges, and compressed lead times present production challenges for producers running older equipment or those contemplating a move into this market. Some developments in equipment and processes that are important to producing secondary structural members include quick-change roll form tooling systems and tooling that can improve the productivity of roofing components- Cee's, Zee's, Eave Struts, Channel, and Base Angle.

Roll forming roofing components for the pre-engineered building and component industries presents unique challenges for fabricators. Tighter profile tolerances, wider product ranges, and compressed lead-times are production challenges for producers running older equipment or those contemplating a move into this market.

Coil Handling

Coil Handling:
The first step in improving roll formed roof framing components starts is coil handling equipment. Keeping the production line fed always has been a process that has a major impact on line productivity, and it is even more important today with the introduction of high-speed punching systems and quick-change roll formers. Reduced lead-times and just-in-time (JIT) manufacturing philosophies have increased the number of daily coil changes, in some cases by tenfold.

Running a complete coil is no longer the norm. Many producers are running a few parts and then switching to another coil, because they are increasingly producing complete buildings to order rather than rolling components to stock.

Many types of coil handling systems are available to help manage the process and improve productivity in this area. Coil storage racks, rotating turnstiles, and coil cars help production personnel stage coils into and away from the production areas. Coil management software is available to help streamline the flow of orders into manageable units that help the operator balance flexibility and productivity; knowing which coil is going to be run next (and the available length of that coil) is just as important as changing coils quickly.

Double-arm uncoilers with powered hold-down rolls allow the operator to prepare the new coil for production while the line is running and secure the partially used coil for offline rebanding, increasing line uptime. Automatic and semiautomatic feed-up systems with band breakers and nose benders reduce the time required to get a new coil into production.

Roll Forming Machine

Roll Forming:
Today's roofing component producers need the ability to change from C to Z to single- or double-slope-eave struts, in a variety of sizes and gauges, all within the confines of a single order.

Some new purlin production systems on the market today offer this flexibility with both automatic and semiautomatic changeover. Eave struts can be produced inline in either single- or double-slope configurations, eliminating an offline bending operation. Positive gauge changes can be manual or automatic, or in some cases accommodated with floating tooling.

Eave struts can be produced inline in either single- or double-slope configurations, eliminating an offline bending operation. Positive gauge changes can be manual or automatic, or in some cases accommodated with floating tooling.

Material Handling:
It may sound basic, but a high-speed purlin production system requires a high-speed material handling system, and a system capable of producing a range of parts requires a material handling system that can handle the full product range.

Controls:
Keeping pace with the change in forming technology, line controls have evolved as well. Machine controls are available with open-architecture operating systems, enabling direct communication with a variety of production control systems. Many of these systems use off-the-shelf components for local serviceability.

Roll forming machine was applied in large quantities Metal Roll forming is a continuous process.Roll forming is a continuous metal forming process that transforms sheet, strip or coiled metal into shapes with a consistent cross section. The stock is fed through successive pairs of rolls, which progressively shape the metal until the desired cross section is produced. Only progressive roll forming (bending) takes place; the metal thickness is not changed except for a slight thinning at the bend radii. the number of the roll former was different depending on the specification of the product. typical the number can be 8 to 30.the more the roll forming steps. the pressure divided into each one was small, duo to the efficien consideration, there is a balance point we should follow. that is way experience is important in roll forming machine products.

What you need to know about roll forming

2011-07-14T07:41:00.000-07:00

Many companies that form a variety of shapes and have a choice of machines that can be used often switch the rolls from one machine to another. The operator usually has no input in choosing the machine, because its selection is treated as a production/scheduling problem. However, the person who does the scheduling does not know that forming rolls are designed for a machine with a specific horizontal center distance, and running them at any other distance will affect how well they work. This basic principle explains why operators are heard to say: "This set of rolls works on Machine A, but we have problems when running it on Machine B." The term "horizontal center distance" is the most misunderstood phrase in roll forming. It refers to distance from the centerline of one forming station to the next

Roll Forming Machine

Does changing the rolls to a machine with a different horizontal center distance mean they will not work? Not necessarily. However, if the horizontal distance is shortened, it is possible that one or more portions of the metal strip will be stretched going from one forming station to another and be permanently wrinkled. The term for this case is "forming too fast."

If the horizontal distance is increased, there is a chance that the profile will spring open between some passes. Wherever a profile opens, the next station must close it back to its original position in addition to doing its share of the forming. It usually is not possible to close the profile to its original position because of localized work hardening of the metal. This phenomenon is called "losing control of the section."

Each metal has a different set of formability characteristics, which includes springback. A set of roll tooling that is designed for a low carbon steel might not work on one of the stainless steels or any metal that has more springback. As a guideline, the only way to determine how much lengthening or shortening the horizontal machine center will affect the performance of a set of forming rolls is to try the rolls at different horizontal distances using the metal in question.

The trend in rollforming is to reduce the thickness of the metal in the part, and maybe change the metal. As a result, the formability of the metal changes. The Purchasing Department orders the new raw stock, and the Sales Department notifies their customers of the availability of an improved product. The Production Department receives notification, so it can plan for a change in volumes for its products.

The operators, however, are not told of the change to the product. Thinner material, with different formability, is brought to the roll forming line, and the operator is expected to produce parts at least as good as the ones they have been making. None of the people involved in making the change is aware that a change in metal thickness affects the performance of the roll tooling.

2011-07-12T02:30:00.000-07:00

Roll forming is a metal bending operation. This is the fundamental principle of the roll forming process. A common mistake that is made when running a rollforming machine is to roughly adjust the first forming passes to get an approximate shape, and then use the last several stations to force the metal into the final shape. An approach like this combines coining, stretching and extruding, and results in a part that is full of internal stresses. If the metal is thin, the part becomes "alive." A test to check if a light gauge profile was formed too fast in the last several rollforming stations is to hold a long piece of the profile by one end and slowly rotate it. If it is alive, it can suddenly snap into a twist along its length.

Roll Forming Machine

Internal stresses within a live section are not consistent, causing problems in secondary operations, like curving or bending. Two pieces that are roll formed by different operators using the same set of tools can look the same, but behave differently. One person adjusted all the forming passes so each pair of rolls did its share of the work, while the other used the last passes to crunch the metal into shape.

Although a rare exception, sometimes the operator cannot obtain a good cross-section without excessive pressure in the last driven passes because of a poor roll design. In other words, the rolls are not capable of forming the product. An experienced operator can determine the capability of a set of roll tooling by setting the roll gaps to do pure bending, and closing them slightly to compensate for the springing apart of the roll spindles under load. The set of tools will have a different capability for each material and material thickness combination that is processed. If the correct shape must be forced into the profile at the end of the forming machine, then part consistency will be difficult to maintain, and will show up in statistical checks or secondary operations.

How to become a successful roll forming manufacturer?

2011-07-05T01:47:00.000-07:00

Industries related to heavy metal perform roll forming, because these metals need to be shaped in different shapes and sizes, pierced and drilled for particular purposes and are cut in accurate measures for industrial needs.Genrally roll forming is required for heavy gauge companies but it can be required in small scale industries too.

A manufacturer of roll forming is not easy sometimes, when some of the same shape to be produced in heavy industry to measure and then completed by a roll forming operation is to strengthen the metal. It strengthens the metal and make them stronger. Metal has to be reformed from the original as it can not be used directly for production. So, for the process of reform and shape them to the fold, and even the brake pump. So how better to gain success in the business of forming rolls is to perform these actions with care to preserve its reputation in the industry.

How to become a successful roll forming manufacturer

The length of the heavy gauge metals is too much and they need to be handled carefully for making then uniform and consistent. Some time the manufacturing process of roll forming desires closer and narrow tolerances to be handled in varied ways. So the industries which perform roll forming should be able to handle these kinds of dense or closer tolerances. Roll forming related industries perform high volume and even fast speed actions, the surface ready should be properly finished and of superior quality. No doubt, it wholly depends on their craftsman ship and their team member’s skillfulness and the management of Roll forming manufacturer.

Overall, good terms are the back bone of each and every business. If the companies work ethically, provide better services then only they can be successful in any of the business. Metallic Roll form business has a bright future ahead, so if you are competitive enough then success is certain.

Roll forming machine application

2011-07-01T00:30:00.000-07:00

Roll forming machine was applied in large quantities of parts with constant complex cross-sectional shapes. Parts often are of long length. As with extrusions, however, short parts can be made by cutting the formed strip to certain length.

Sheet thickness can be 0.13 mm to 25 mm was processed. However, except for heavy-wall welded steel pipe and structural members made by this process, normal commercial limits are 0.25 to 4 mm Processible widths range from 25 mm to 21/2 m (1 to 100 in). however, 1 m(40 in) is a common commercial maximum, and 400 mm (16 in) is the thinest processible on the most commonly available roll forming machines. Deep forms are difficult; 100 mm (4 in)is a practical depth limit for easily made cross-sectional shapes.

Roll Forming Machine Process

Roll forming Machine components have many applications, especially when mass production is involved. In the building industry, components manufactured by this process include roof and siding panels, purlins, joists and studs, window frames, door-trim ridge rolls, downspouts, architectural trim, and copper electrical conductors.

Appliance parts made by roll forming include panels for stoves, refrigerators, and other appliances, particularly when wraparound forms are involved, refrigerator shelves, and lighting-fixture parts. Curtain rods and tracks for sliding doors and draperies, drawer handles, and metal picture-frame members are also made by roll forming. When curling (longitudinal-bending) equipment is included in the roll forming line, such parts as bicycle fenders and wheels, quonset-hut frames and roofing, barrel hoops, drum rings, and bezels are formed.

Roll forming can be carried out with planted, galvanized, lithographed, vinyl-coated, and painted stock (if the paint is baked and the roll forming is not too severe or if a bendable-paint formulation is used ). Dual-layered components also can be made at one time. These may include bimetallic parts such as those made when a thin stain-less-steel facing sheet and a carbon steel support sheet are roll forming together or when fiber, paper, asbestos, or rubber inserts are places in a metallic form.

Long pieces such as railroad-car and truck-trailer trim members can be made with this roll forming process. The maximum length of parts is dictated only by application requirements and handling conditions. Figure illustrates some typical cross sections that can be produced by this roll forming process.

Why roll forming

2011-06-29T01:53:00.000-07:00

roll forming, is a process of continuous bending in which a long strip of metal like coiled steel is put through consecutive sets of rolls, or stands, each of them are bending a part of the metal, until the required cross-section shape is obtained. Roll forming is good for producing parts which are long in lengths or needed in large quantities. The process of roll forming is one of the most simplest manufacturing processes for the roll forming manufacturers. It generally begins with a large spool of metal strips, which are generally between 1 inch to 20 inch in width, and about 0.0004 to 0.125 inch in thickness. These sheets are held together by a device known as 'dispenser'. After this process, the metal sheet is unrolled and put in to the machine which has stock feeder in the beginning and is connected to a cut off attachment. After the sheet is passed through the cut off attachment, it is then fed into the forming rolls. These mating die-set rolls do the job of constructing to form the desired shapes, and this is done in sequential stages by various shaped rolls.

Roll Forming Machine

The layout of these rolls can be in any different roll configuration like flower shaped or progressive upper and lower rolls, or the side rolls, or even overhung spindle rolls which are also known as cluster roll configurations. Steel is also a very important material used for framing and cladding roofs and walls. Houses which are made of steel are easily erectable and can be insulated. They are earthquake resistant, cost effective too. Due to roll forming, the architects and designers can now give wings to their imagination .it is also very convenient for the manufacturer because it requires less labor.

There are several different kinds of roll forming machines, which can be purchased and also be developed to fit the specifications of cross-section. The name of some of the roll forming machineries are rollforming presses, Purlinmaster Rollformers, Stud and Track Rollformers, Workhorse Series Roll formers and Greenfield Stud Rollforming Lines. These Rollforming machineries are used in a number of industries like in the building construction industry, for garage doors, for automotive, shelving and other complex parts.

The future of the building industry can be improved if there are advances in the processes of roll form. Modern roll form system is a integrated fully computerized system for handling, processing, and finishing the material with better efficiency and economically.

Roll forming is a high-speed, high volume production process, which uses a roll forming machine to convert metal sheets or coils into parts as the metal moves through the machine. As the material passes through the machine, rolls situated on both the top and bottom of the machine apply pressure to bend the material thus forming various configurations. Roll forming is a metal roll forming process that is suitable in the fabrication of stainless steel, copper, aluminum and steel products.

Manufacturers use roll forming to create standard parts that include angles, rings, channels and other forms. Some manufacturers can also provide custom roll forming. Many industries rely on roll forming services to fabricate products, which can be utilized in rail cars, door frames and helicopter blades. The advantages of using roll forming services to create these parts are quick and efficient accommodation of high volume orders, diverse range of shapes created with this process and greater uniformity/ consistency of parts.

Corrugated Metal Roofing

2011-05-24T02:11:00.000-07:00

Corrugated metal roofing has been in use since ages to cover factories, outhouses and barns, and has always been considered merely functional as well as ugly to look at. However, these days, people are looking at those early outhouses and barns with their corrugated metal roofing with a new mindset and are discovering that they do have a certain aesthetic appeal. Therefore, corrugated metal roofing is growing in popularity with people finding innovative ways to use it to beautify the roofs of their homes.

Corrugated Metal Roofing

Needless to say that the corrugated metal roofing available these days are nothing like the ones that were used in the past. They have been modernized to suit today’s styles in housing. Advances in technology has made it possible to treat and coat them to prevent them from wearing out or rusting, thus making them long lasting and able to withstand the elements. New types of materials, which are being produced these days, make them far more durable compared to other roofing materials. Some of the types of corrugated metal roofing available these days include aluminum, galvanized steel, metal with naturally oxidized finishing, steel or aluminum with pre-painted finishes, and so on.

As its very name describes it, corrugated metal roofing is made up of alternating parallel ridges and grooves. Each sheet of metal has a wavy pattern akin to corrugated cardboard, serving the same purpose, of being strong while also remaining relatively lightweight. For instance, if you use a double layer of roofing material made of metal, not only would it weigh double but would also be doubly costlier compared to corrugated metal roofing, which would provide the same durability and strength, without the additional expense.

These days, with lighter buildings coming up, it has become essential to use lightweight roofing material, because heavyweight roofing can put inordinate strain and stress on structures, with the potential of damaging and degrading the supports of the house comparatively faster. Apart from corrugated metal roofing being less stressful for your house, it is also able to withstand the effects of inclement weather far better compared to other types of roofing.

Aside from protecting your home actively against severe weather conditions, corrugated metal roofing will also reduce your energy bill quite substantially, by keeping the heat in during the winter. This is mainly because, being so lightweight, it permits you to install additional insulation under the corrugated metal sheets.

The technique used for installing corrugated metal roofing is one of the main reasons that it is able to resist the most inclement of weather conditions such as tornadoes and hurricanes. It will hold out against almost everything, and rarely does it develop weaknesses or faults, hence it has the potential of keeping on protecting your house for even a lifetime. Plus, it will not show any wear and tear, continuing to look almost as good as new even years later, which makes it a sound and wise investment.

Galvanized Steel Roofing

Galvanized steel roofing is very popular, due to its toughness and durability. Read on to know more about this roofing material

It is a common fact that roofing is one of the vital parts of any construction. So, it must be made of materials that are strong and durable. Even the looks of the construction depends to some extent, on the type of the roofing material and so, you must choose the right type. There are many different types of roofing materials that are made of metals, fiberglass, asphalt, plastic, etc. This article will provide you with some information about galvanized steel roofing.

Galvanized Steel Roofing

What is Galvanized Steel Roofing
The concept of metal roofing was introduced in the latter half of the nineteenth century. Soon, it became so popular that these products were used extensively, for industrial, agricultural and even commercial purposes. However, the use of metal roofing declined gradually, as it was prone to rust and certain other problems. But, now these problems are overcome with advanced technology. At present, there are several varieties of metal roofing in the market and those made with steel are one of the popular types. Even in case of steel roofing, there are various versions, like, stainless steel roofing, corrugated types, galvanized steel roofing, etc. Let us look at what is galvanized steel and what are its features.

Galvanization is a process, in which metals like, iron, steel or aluminum, is coated with zinc. To be more precise, the metal (to be galvanized) is passed through molten zinc, at a temperature of 460°C, so that it reacts with zinc and forms a zinc carbonate on the surfaces. The inner layers contain both zinc and metal and the innermost is pure metal. Through galvanization, the metal is made free of rust and corrosion. Galvanization provides a protective covering for the inner metal. Even though metals like aluminum are used for galvanizing, it is galvanized steel that is found to be more popular and this is due to the heavier weight and durability of the latter. So, use of galvanized steel is mostly found in outdoor constructions. While this type of steel is used to make nails, beams, screws, etc. galvanized roofing sheets are very popular for roofing and siding purposes. You may also read more about corrugated sheet metal roofing.

Galvanized Steel Roofing - Pros and Cons
As mentioned above, galvanized steel roofs are those roofing materials that are made of steel, but have undergone galvanization. This type of steel roofing material is available in different forms like, tile sheets, composite panels, corrugated roofing sheets, steel roofing shingles, etc. Galvanized steel roofing is tough and durable. It is also resistant to rust and corrosion. This roofing material is said to withstand storm, hail, snow, etc. It is also fire resistant. Being lightweight, galvanized steel roofing is easy to install. If you have speculations about its resistance to hailstorms, you may go for galvanized steel with heavy gauges and high qualities. This roofing, when painted in light shades, can also reduce your cooling costs, as it can reflect heat. However, plain galvanized steel roofing has a silvery surface that shines and this may result in glares and reflections that may be annoying for many. In case of corrugated galvanized steel roof, some people prefer pouring concrete over the roofing, so as to make it strong. Even the reflection problem will not arise in such cases. As compared to stainless steel roofs, galvanized steel roofs are less expensive.

In short, galvanized steel roofing is one of the popular choices, if you are looking for a metal roof, for your construction. The above said is only a brief overview about this product and so, it will be better to gain some extra knowledge about this roofing material, before investing in it. Make sure that it is appropriate for your requirements.

Did you know white-painted metal roofing has the highest solar reflectance value of any roofing product available and can save you up to 40% of your annual energy bills?

More and more, homeowners are seeking out energy-saving building materials for their renovations and new homes, products that not only secure and improve structures but also provide long-term cost-cutting on energy bills while promoting environmental and economic sustainability in the greater community.

Among the array of possible upgrades, "cool metal roofing" easily answers this consumer demand offering a solid, attractive roofing solution available in multiple colors, textures, and profiles, for steep-slope and low-slope applications, that can save your household up to 40% of its annual energy costs, depending on your geographical region.

Cool Metal Roofing

The Benefits of Energy Efficient Metal Roofing
As reported by the Cool Metal Roofing Coalition and the Oak Ridge National Laboratory, installation of reflective metal roofing can save your home up to 40% in summer cooling energy costs while highly emissive metal roofs can reduce urban air temperatures by as much as 12 ° F. Combined, these benefits mean less money out of your wallet, less dependence on energy resources and less general air pollution in your neighborhood and across the nation.
While asphalt traps heat... Metal Roofs reflect solar energy... And pigments re-emit heat.

The secret to metal roofing's energy savings is in its variety of finishes. As shown above, the basic, unpainted metal roof will reflect much of the solar radiation usually absorbed in your attic and home by an asphalt roof. But, for homes in warmer climates, pre-painted or granular coated metal roofing systems not only reflect solar energy but also cool your home by re-emitting most of what solar radiation is absorbed.Where annual cooling loads dominate, a highly reflective and highly emissive painted or granular-coated metal roof is optimal for reducing energy consumption and can actually re-emit up to 90% of absorbed solar radiation.
Additionally, most metal roofing, including standing seam, is composed of recycled material and can be installed directly onto an existing asphalt roof, reducing landfill waste and promoting quick installation as well as decades of environmentally-sound, maintenance-free strength and beauty.
