Spray Polyurethane Foam (SPF) can adhere to almost any type of roofing material (like steel, concrete and wood). Because of this, it’s a smart, environmentally friendly commercial roofing choice because old roofing doesn’t have to be removed and fill up landfills.

Spray foam can be applied as a tapered roof system, and cants and vertical wall terminations can be covered in SPF. This eliminates the cost of extra insulation systems and flashing materials. SPF roofing is also a time & cost saving roofing system.

How is SPF applied?

Spray foam (Premiseal) starts out as a liquid and then expands to about 30 times its volume to form a sturdy, closed cell roofing material. The resulting product is seamless, so the risk of leaks is reduced greatly. SPF completely adheres to the substrate, so it’s weather tight. It’s also very lightweight despite its strength.

A layer of elastomeric coating (Premicote) is applied after the spray polyurethane foam has been applied to the desired thickness. The final coating is durable and can be walked on for maintenance.

How Long Does Spray Polyurethane Foam Last?

An SPF roof can last for a long time if it is properly maintained (it will need cleaning, priming and possible recoating every 10-15 years). If proper care is maintained, the roof could last for over 50 years.

What’s the Cost of Spray Foam Roofing?

The cost of spray foam roofing application depends on several factors like complexity of project, foam thickness desired, location etc. Costs can start at about $2.50 per board foot and climb from there.
