Engineered for Re-Roofing…
One of the best features of Gerard Stone-Coated Steel Roofing is that it was engineered for re-roofing. It is lightweight, only 1.3 lbs. per sq. foot, and will not add any significant weight to the structure. It is only 1/3 the weight of asphalt shingles. It will not conform to an uneven surface below it, and can be installed to “encase” the old roof. This allows for installation over an asphalt shingle roof without the need to tear-off the old roof in most cases.
Removing the old asphalt shingle roof is necessary if your re-roofing with an asphalt shingle. Asphalt shingle warranties state clearly: “Must be applied over a smooth flat surface”. An asphalt shingle will conform to the uneven surface of an existing asphalt shingle roof.
The shingle will be much more susceptible to cracking, blowing off, and premature failure. Our metal shakes and shingles do NOT conform to the irregular surface of an asphalt shingle roof and in fact, it can hide imperfections in the roof deck, existing roof and roof framing.
Asphalt Shingles, (being a petroleum based building material), are rising in cost rapidly. That, combined with the high cost of labor and disposal fees of tearing-off an existing asphalt roof, the cost of installing a lifetime metal roof has become a lot more comparable to re-roofing with an asphalt shingle. In addition, consider these statistics on asphalt shingles:
- 12 million tons created annually
- 11 million tons post consumer tear-off debris
- 1 million tons of manufacturing waste
- contractors spend $1billion yearly in waste hauling and disposal fees
- clogs landfills, utilizing over 4% of all space
- requires several generations to decompose
The age of temporary roof systems is coming to an end. Life Cycle Cost, No Mess, No Crushed Flowers and Landscaping, No Disposal Fees, No Additional Tear-off Labor, and NO need to Re-roof every 10-15 years are just a few reasons to consider a Stone-Coated Steel Roof from Bjorkstrand Metal Roofing.
