STEEL

STEEL isn't just steel anymore — Today, steel is the most recycled product on earth and Prosteel suppliers use state-of-the-art production facilities to ensure that high quality, long-life steel goes into every roof we sell.

PROSTEEL Steel — We use the performance proven and highly corrosion-resistant AZ-50 hot-dipped Aluminum—Zinc alloy coated (top & bottom) steel. This type of coating is traditionally branded as *Galvalume® steel, and is specially designed for exterior construction where the best corrosion resistance is demanded.

THE Prosteel difference — After our steel supplier applies the AZ-50 coating, Prosteel Steel undergoes additional treatment, where they apply a proprietary designed primer, on the top-side of the steel coil. It is this unique primer that enhances and promotes long-life adhesion of Prosteel’s specially formulated acrylic polymer basecoat that is applied at our factory during the panels coating process, where finely graded & non-oiled stone-chip is applied to the steel pressings.

The result is a long-life roof panel in either Shingle, Shake or Tile designs to suit any architecture, that’s warranted for 120-mph winds, Class-4 Hail resistance and for 50-years against corrosion.

 

STONE CHIP

 

STONE coated steel roofing— Has been protecting structures around the world for nearly 50-years. With a heart of steel and a solid coating of stone chip it can withstand virtually whatever nature wants to throw at it.

PROSTEEL Stone — Is specially graded, natural granite in an extremely fine grade, angular faceted chip to increase coating coverage per-square inch. If we can apply more granules per-square inch to each panel, the longer the life the coating will be.

THE Prosteel difference — We didn't stop at a fine grade of chip, we pursued experimentation with our supplier to develop an industry first — a stone chip that’s OIL-FREE. A critical element when using water miscible acrylic-polymer technology. It is this unique OIL-FREE condition of the Prosteel fine 18-grade stone chip that separates us from the competition and ensures the best adhesion of stone chip coated panels on the market.

The result is a long-life roof, in either Shingle, Shake or Tile designs to suit any architecture, that’s warranted for 120-mph winds, Class-4 Hail resistance and for 50-years against corrosion.

 

 

 

SMART Acc

 SMART Roofs for Smart People™ — Prosteel offers a full line of SMART accessories that are easy to install yet functional, blending perfectly with a Prosteel roof. Whether it’s the easy to install and fully integrated SMARTVent, ventilator panel or the unique SMART-Jacks & SMART-Sleeves for roof-pipe penetrations, all are stone-coated and add up to the best accessory line in the business.

Prosteel’s SMART design can also be found on such standard items as its Shingle & Shake RAKE Channel’s that incorporate the installer friendly ’Locator-Lip’. This ’locking-lip’ design is also on the new series of Panel Riser metals (Stone-Coated) that is most noticeable on Prosteel Roman Tile installs at the fascia.

THE Prosteel difference — We continue to develop new & exciting accessory items to work perfectly with Prosteel roofs. The result is a long-life roof, in either Shingle, Shake or Tile designs to suit any architecture, that carries a 50-year limited corrosion warranty to protect your investment.

 

SNOW & ICE

 

STONE Coated Steel Roofing— Has been protecting structures around the world for over 50years. With a heart of steel and attractive stone coating it can withstand virtually whatever nature has to offer including cold climates.

THE PROSTEEL Panel — Design works perfectly in severe cold-climates where ice-damming is a problem, the shape of ProsteelCOTTAGE™ Shingle, ProsteelSHAKE®, Prosteel TILE® & ProsteelROMAN-TILE® provide an “Above Sheathing Ventilated” (ASV) space across the roof deck and its this horizontal and vertical air-space blanket that has proven to provide exceptional cold climate performance especially in areas where high snowfall and ice damming is a problem. Calgary, Alberta, Canada is a classic example due to the seasonal Chinook winds that can create 60-degree + temperature swings within a 24-hr period. Thousands of homes in some of America’s coldest climates such as Utah, Colorado, Minnesota, Wisconsin & the Dakota states enjoy excellent cold weather performance because of the Prosteel panel design and the ASV that limits icicles and ice damming as shown above.

THE Prosteel Difference — A long-life roof, in either a Shingle, Shake or Tile profile to suit any architecture in virtually any climate, warranted for 120-mph winds, Class-4 Hail resistance, 50-years against corrosion, all while protecting your home and standing up to mother nature in some of the worst snow & ice climates in north America, confirming your Prosteel roof is truly a - Smart Roof for Smart People.

BATTEN-LESS

BATTEN-LESS Panels— Prosteel offers its Shake & Tile profiles in an innovative design, allowing them to exceed the wind-uplift strength of panels installed with battens. The uniqueness is in the panels back-flange, angled nose sections and twice as many fasteners in an ‘X’ pattern as a battened panel. It’s these Prosteel Batten-Less attributes that in December of 2005 during (1)Wind-Uplift testing at UL in Chicago proved that batten-less panels can out-perform Prosteel’s battened systems for uplift resistance. In one test UL’s Uplift test chamber was pushed to an all time high of 307-psf uplift force. The test report reads;

 

The most stringent wind-uplift region of the US is in Dade County FL and their Product Control Approval known as an NOA defines the Maximum Design Uplift Pressure a product can withstand after applying the standard safety factor of 2 to the tested pressures. (2)153.5-psf is Prosteel’s Dade NOA pressure the highest of any stone-coated steel panel on the market today. Its this sort of performance that clearly answers ‘Why Prosteel?’

BATTEN-LESS Difference — Homeowners receive an immediate benefit by going ‘Batten-Less’ - making the Prosteel panels easy to walk on and earthquake strong due to their interlocking design and direct to the roof deck installation.

The unique double fastening ‘X’ pattern of fasteners is what allows the Prosteel Batten-Less panel to be currently, the (3)highest uplift rated stone-coated steel roof panel in the industry. Perfect for the extreme highwind coastal requirements of Florida.

HAIL

HAIL YES! — Installing a Prosteel stone-coated steel roof in any profile (ProsteelSHAKE®, ProsteelTILE®, ProsteelROMAN®, ProsteelCOTTAGE™ or ProsteelSHINGLE®) gives you the added assurance you are protecting the structure with one of the best possible roof materials warranted & designed to withstand annual hail storms.

PROSTEEL Stone-Coated Steel Roofs — Are UL-Listed, carrying a Class-4 UL Impact Rating—the highest available for roofing products. Prosteel’s limited warranty provides coverage against hail penetrating the steel panel substrate completely or splits / cracks at the hail-stone impact point.

THE Prosteel difference — Prosteel panels (ProsteelSHAKE®, ProsteelTILE®, ProsteelCOTTAGE™ & ProsteelROMAN®) interlock left to right and vertically and due to their modular exposed fastener design allow for easy removal and replacement of individual panels within a roof section, making repairs a simple process. This design feature has been an asset in some high wind prone areas where trees have impacted roofs and the Prosteel roof was easily repaired without the need to disrupt entire roof sections. Some insurance companies regionally provide discounts on annual premiums if you install a Class-4 Impact Resistant rated roof, be sure to check with your local insurance broker.

The result is a long-life roof panel in various profiles suitable to virtually any architecture, that’s warranted for 120-mph winds, Class-4 Hail resistance and for 50-years against corrosion, - Smart protection from a Smart Roof! Prosteel

WIND

High Wind— Prosteel roofing installed with standard fastening pattern is covered under the 120-mph wind warranty. This is enough for most areas of the country but not all. The most stringent uplift pressure for residential roofs is in Dade County FL and is the “150-mph Exp-’C’, Zone-3 ‘Corner’ which requires this section of a roof to withstand 109.9-psf uplift force.

Prosteel—Tested to Extremes— Wind-Uplift testing at UL in Chicago proved that Prosteel batten-less panels can out-perform our battened systems for uplift resistance. In one test UL’s Uplift test chamber was pushed to an all time high of 307-psf uplift force. The test report reads;

“Prior to and during the attainment of the 307-psf pressure, there was no sign of fastener pull-out or damage to any of the panels. The roofing system did not fail, the maximum capacity of the apparatus was reached.”

Its this sort of performance that clearly answers ‘Why Prosteel?’

Prosteel SMART wind Design- To support the Prosteel team of contractors, we now have two (2) options for permit applications in High Wind areas, commonly referred to as HVHZ areas (High Velocity Hurricane Zone). Copies of the Prosteel’s HVHZ approvals can be found on our website at the following link. (http://www.metroroofs.com/ highwind.html) . In both approvals Miami-Dade NOA # 06-0911.05 and FL # 6710 the contractor can select either a Batten application or a Direct-to-Deck install. For steep pitched roofs the Batten application allows a grid system for the installers to walk on while the Direct-toDeck batten-Less method ensures high-wind security using the double ‘X’ pattern of fasteners.

Warranty

 

Limited 50/25 Warranty— Prosteel covers all its stone-coated steel roofs with a full 50-year warranty on the panels against corrosion or manufacturing defects and a 25-year warranty on the surface coating against loss of stone-chip.

Either way you're well covered both by a long-life Prosteel roof and its accompanying limited 50-year warranty.

 

SMART-Ventilation ASV

 

 

SMART-Ventilation ASV = Above Sheathing Ventilation — ProsteelTILE®, ProsteelSHAKE®, ProsteelROMAN® panels meet California’s Title-24 Energy Code due to their built-in design that creates an Above Sheathing Ventilated (ASV) space above the spaced or solid sheathed roof deck.

The ORNL (Oakridge National laboratory) recent study in TN, Jan-2012) concluded that Prosteel panels that create a minimum 3/4-inch (ASV) air space is equivalent to a roof with cool colors (25% solar reflectance), irrelevant of the Prosteel roof color.

THE Prosteel difference — Contractors can now provide energy savings benefits to their customers simply by installing the Prosteel panels (Tile, Shake & Roman), creating an ASV configuration.
