WHY
Hail Storm Protection
Hail Storms up to Class 4 are covered under the standard warranty from Granite Steel approved suppliers DECRA™ and Unified Steel™. While traditional roofing materials are notoriously susceptible to hail-caused damage in the forms of denting, cracking, splitting, stone-coated metal materials withstand the force.
Hail Storm Limited Warranty
Roof strives for continual improvement safety, production, quality, profit and continued community service toYZ strives for continual improve ment in safety, production, quality.
Class A Fire-Rating
DECRA's interlocking panels are strong and non-combustible and they are covered by a transferable lifetime Limited Warranty.
Up to 50 Degree Differential in Attic Temperature
Sunlight-repelling, non-porous, interlocking stone-coated metal roof panels boast less heat / cold retention than any other. Furthermore, with DECRA's Above Sheathing Ventilation (ASV), airflow is permitted through channels that allow hot-air to pass through without being absorbed by the panels or subsequent underlayment, sheaths and attic space. All of these lead to less heat, less energy required to counter and hence lower energy bills. In an independent study, an Asphalt Shingle roof attic temperature reached 147 degrees, where its 'Direct-to-Deck (ASV method) Stone Coated Metal roofing system was 89 degrees.
Hurricane Force* Wind Protection + Warranty
Granite Steel and its suppliers offer 120 MPH Wind Warranty. Wind speeds above 39 and 74 MPH constitute Tropical Storm and Hurricane force winds respectively.
1.5 LB / Square Foot
Weighing in at a fraction of traditional roofing materials, including petroleum-based shingles, the benefits to a lightweight roof are immense. It positively effects everything from energy efficiency (heat retention / absorption), upholding additional weight brought on by snow, attic heat retention, weight distribution when canvasing and more.
Industry-Leading 50-Year Warranty*
A guarantee / warranty you cannot get with traditional roofing materials, stone-coated metal roofs are the most durable materials while offering the same or enhanced curb-appeal. In fact, traditional roofs will need replacement 2.5 times during the lifespan of a stone-coated metal roof. This does not include the unexpected costs associated with repair which are all but eliminated with the superior product.
