Spray Polyurethane Foam (SPF) is a second coat of protection for metal roofs, while creating a slope for the drainage system and building thermal resistance for the home against extremely cold weather and other chilly disturbances.
An SPF-based foam roofing system functions like the home’s shield in various ways. It weatherproofs the house against the bad elements of a climate or a season gone bad. A properly foam roof installation shelters the roof from artificial damages and is made to be fire-resistant enough to help deter the spread of flames into other parts of the house should these break out in a fire accident.
