A White Shield roof is the ultimate in environmental protection. This system comes with a minimum R-Value of 30, which would bring a standard 20,000 square foot building with 20' high ceilings to within an R-20. If you like these numbers, then you'll certainly appreciate that this roof will also help cut energy use in the building in half and is at least 3 times more insulating than a standard competitor's roof and twice as comforting, especially when it comes to peace of mind in the long run. Every White Shield roof comes with a 25-year warranty backed with an incredible 40 year proven life expectancy. Depending on the specific roofing problem that needs resolving and the requirements of your building and its occupants, a White Shield Roofing System utilizes up to 80 mil. membranes from trusted suppliers who have proven themselves worthy in the field and not just on paper. We've set our standards so high on this system that you simply won't find longer lasting or more sustainable protection from the elements, or anything else for that matter, than this.
