ProsteelSHAKE® Metal Shake Roofing

ProsteelSHAKE® shake metal roofing panels outperform natural cedar shakes, composite shakes and light weight painted metal shakes in every comparison, and the Prosteel batten-less steel shake alternative eliminates costly wood battens and allows faster roof installation times. Each Prosteel steel shake roofing panel is forged with deep wood grain impressions, creating an exceptionally strong, secure steel roof covering for any architectural style. All Prosteel shake metal roofing products provide high quality warranty performance, including fire resistance and against wind speeds from 120mph to damaging hail. ProsteelSHAKE® steel roof panels are finished with an attractive stone coating and embedded in a UV resistant acrylic polymer for a lasting bond to Zincalume® steel.

Comparing Metal with Traditional Shake Maintenance Costs

 

Natural cedar shakes and  treated wood shake roofing is a lot more expensive to maintain when compared to ProsteelSHAKE® metal shake roofing products. A new metal shake roof installation will initially cost more than a natural wood shake roof, but over time, the steel coated roof will outlast the natural wood roof by a factor of up to 4 times or more.

Traditional concrete and clay shake style roofing is heavy and absorbs moisture, which promotes algae, fungus and mold, requiring the roof to be cleaned and maintained on a regular basis. Natural wood shakes also absorb moisture and are prone to being blown off, buckling, cracking and can be a fire hazard. A ProsteelSHAKE® roof does not suffer from any of these traditional roofing materials failures. How much does metal shake roofing cost? A steel coated metal shake roof costs a lot less than any cedar shake alternatives, especially when you factor in the maintenance and replacement costs of a traditional roof. A ProsteelSHAKE® metal tile roof is a great investment that will keep your home or building looking beautiful while saving you money and time in the long run.

Frequently Asked Questions

Q. How Long Has Stone-Coated Roofing Been Around?

Stone-coated steel roofs occurred during World War II when tar & sand were used to cover galvanized steel bunkers. After the war, the practice was commercialized and the first roofs were produced. Stone coated steel roofs have been protecting buildings for over 55-years, but the product technology today bears little resemblance to early practices due to advances in the chemistry of coatings and acrylics.

Q. Will A Steel Roof Make My Home Hot?

No. A properly vented steel roof moves air both between the shingles and the underlying deck as well as moving air from vents under the decking. Heated air is allowed to dissipate through the ridgeline as cooler is drawn through eave vents. Reduced energy bills can result from airflow both under and over the decking.

Q. Can You Walk On A Steel Roof?

Yes. Some care must be exercised while walking on the roof, but note that roofers walk all over the shingles during the installation process

Q. Is a Steel Roof Noisey In The Rain?

The combination of dead-air space and the stone coating minimize outside sounds. One rural couple standing directly under a stone coated steel roof observed that they could hear the rain striking a metal building about 50-feet away, but couldn’t hear any noise from the stone coated steel roof directly overhead.

Q. How Wind Resistant Is a Steel Roof

Prosteel roofing panels have been proven to resist wind speeds in excess of 120-mph. One homeowner’s roof survived tornado force winds completely intact. “We lost 12 large trees…the shingled roof of our garage…a 14' X 14' (2" X 6") pump house deck slammed into the house and buckled the brick. You said it would hold up in a tornado. I’m writing to tell you it will.” Bill Jamieson

Q. How Do The Granuals Stay Bonded To The Steel

Specially graded ‘Non-Oiled’ natural granite stone chips, produced by SGI Corporation are used for all Prosteel stone-coated products. The granules are embedded in a UV resistant acrylic polymer for a lasting bond to the steel substrate

Q. Will A Steel Roof Rust?

The steel substrate is protected from corrosion by layers of metallic and polymer coatings. Prosteel has an advanced metal composite developed by BIEC International and introduced in 1973 as aluminum-zinc coated steel. The composite improved earlier metallic coatings by applying an aluminum-zinc alloy to the steel in a continuous hot dip process. The aluminum creates a barrier coat while enhancing the long-term performance of zinc and its ability to protect breaks in the coating. Galvalume® coated steel has repeatedly been shown in industry studies, conducted over the last 30-years, to outperform the corrosion resistance of other coated metals. This is why the Prosteel roofing panel is referred to as “The final Roof”, and is backed up with a 50-year limited warranty.

Q. Does The Color Fade?

Though sized more precisely, Prosteel uses the same stone granules used by asphalt shingle manufacturers for over 50-years, so history demonstrates that fading is not a problem. Over time, a slight change in color may occur due to settling of airborne contaminants; however periodic rain or washing the roof with a garden hose will keep the roof looking new.

Q. Is a Steel Roof Fire Safe?

Steel roofing is classified as a noncombustible roofing material (Class A). Prosteel panels when installed over combustible materials like wood shakes or shingles, the resulting roof assembly can be classified as A, B or C depending upon the type of underlay installed between the old roof and new roof. The lightweight (1.5-lbs/Sq-ft) strength of the steel roof helps prevent roof collapse onto occupants exposed to fire within their residence. top There are many examples of the safe fire performance of stone-coated steel roofs in areas subjected to fire storms. Additionally, the lightweight strength of the steel roofing precludes it from crashing down on occupants exposed to fire within their residence.

Q. How Long Does It Take To Install A Steel Roof?

Usually only a few days. The complexity of the building’s roof is the primary factor in determining the time required. Complex roofs require more time than basic designs.

Q. What IS The Installed Weight Of A Steel Roof In Comparison To Other Products?

 

PRODUCTWGT. PER SQ. (1-Sq. = 100 Sq.ft)
Steel Roofing125 lbs.
Standard (3-Tab) Asphalt Shingles**190 – 215 lbs.**
Wood Shake/Shingle*250 – 300 lbs.*
Heavy Weight Laminated Asphalt Shingles**290 – 430 lbs.**
Clay / Concrete Tiles*900 – 1200 lbs.*

Cedar, Clay & Concrete product weights are all DRY weights, all 3-product weights increase when WET. **Asphalt Shingle weights DO NOT include the weight of new plywood. OSB sheathing.

Q. What Does Hail Do To Steel Roofs?

Prosteel panels have earned a UL Class-4 Impact Resistance rating from Underwriters Laboratories. Except under the most extreme storms, Prosteel panels show no visible effects from impacting hail stones. Some insurance carriers extend a discount on premiums to homeowners that have a UL Class-4 Prosteel roof.

Q. Are Steel Roofs More Susceptible To Lightling Strikes? 

Steel roofing is no more susceptible to lightning than other roofing materials. It has been demonstrated that lightning strikes most frequently the highest points of terrain. Where concerns exist, lightning rods can be installed on roofs that are the highest point of surrounding terrain

Q. How Does Prosteel Market Its Products? 

Prosteel sells its products ONLY through wholesale type distributors who in turn sell to local contractors.
