Quick answer
Spray polyurethane foam (SPF) roofing is a seamless system that insulates at R-6.5 per inch and waterproofs your building in a single application, cutting energy costs and stopping leaks around every penetration.
Why SPF fits the Inland Northwest
Spokane and North Idaho swing from below zero winter nights to 100 degree summer afternoons. SPF expands and contracts with the building, so it does not crack at the transitions where traditional roofs fail first.
Because the foam is continuous, there are no seams, no fasteners, and no laps for water to sneak through, key for buildings that see wind-driven rain and heavy snowmelt.
Real energy savings
SPF gives R-6.5 per inch, the highest R-value of any common commercial roof insulation. Owners commonly report 20 to 30 percent lower heating and cooling bills after switching, and warehouses see the biggest wins.
A bright reflective silicone or acrylic top coat keeps the roof cool in summer and blocks UV so the foam lasts.
Where SPF is worth it
Flat and low-slope commercial roofs, buildings with dozens of HVAC penetrations, roofs with mild ponding water, and older roofs that need both insulation and waterproofing at once are all strong candidates.
SPF is fully renewable, re-coat every 10 to 20 years and the roof effectively lasts as long as the building.
Frequently asked
- SPF roofing in the Spokane market typically runs $4.50 to $7.50 per square foot installed, depending on foam thickness, top coat, and prep.
