Spray Polyurethane Foam Roofing (SPF) Installation and Repair
As the name implies, SPF is a polyurethane foam that is applied by spraying directly onto an existing roof surface. The liquid concoction turns to foam as it is applied and forms a UV protective coating that’s typically at least 1” thick. Because it is sprayed on, there are no seams or air gaps between the coating and the roof. This provides excellent thermal insulation, as well as resistance to water ponding.
SPF roofing is widely used on the roofs of commercial and industrial buildings. While installation of an SPF roof is extremely easy compared to other roofing systems (no need to tear off the old roof!), the materials cost more. With the money saved on installation costs, though, an SPF roof will generally cost less than other roofing systems, and you have a roof that is highly unlikely to give you any water leak headaches.
One thing to keep in mind: SPF roofs need to be recoated every ten years. If the protective coating is worn off before it gets recoated, the entire sprayed-on roof may need to be torn off. With a minimal amount of care and attention to recoating, though, an SPF roof can easily last 50 years or more.
