Want more energy savings? We can add spray polyurethane foam roofing to the metal deck before the coating process. SPF roofing is rated at almost R-7 per inch, which makes it twice the insulation value of most other insulating products. And, it's seamless, self flashing, and qualifies and a thermal, air and moisture barrier making it the "King" of all the insulating products. If Spray foam is used on your roof, it can even pay for itself in as little as five years. With warranty periods of 10+ years for this type of system, it's like getting a free roof.
