Sprayed Polyurethane Foam (SPF) is a fully adhered, closed-cell roofing material providing a seamless, durable waterproof covering that bonds tightly to a properly prepared surface. The elimination of seams and joints eliminates the primary source of roof leaks. It is typically applied to a thickness of 1 to 2 inches to form a monolithic surface while incorporating flashings, penetrations and parapet walls.
Independent studies prove SPF systems are highly dependable, long lasting, and very affordable. Many SPF roofs have been in place for more than 35 years—properly maintained, these roofs could last indefinitely.
SPF’s aged insulating R-value of 6.5 per inch of thickness provides more thermal resistance with less material than any other type of roofing insulation. Because SPF is lightweight, it can be applied over most existing roof systems without exceeding the structural load capacity, and can be shaped or sloped as needed to improve roof drainage. SPF can be applied directly over single-ply, built up roofs, concrete, metal and wood substrates. Consequently, there is rarely need for tear-off, reducing installation times, business disruption, roofing debris in landfills, and installation costs.
PUFF foam and coating systems are energy-efficient, low maintenance and versatile roofing systems ideal for commercial, industrial and government roofing needs.
Benefits of Foam and Coating
- Eliminates seams and joints – creates a monolithic membrane that eliminates the needs for mechanical fasteners. Can also be applied to walls and vertical surfaces.
- Creates proper drainage. By spraying directly to the roof surface, can vary thickness of foam, directing water-flow to drains. Minimizes standing water and roof leaks.
- With proper preparation, can be applied to almost any roof surface.
- 5-, 10-, 15- and 20-year full system warranties available.
- In many cases roofs can be recovered or repaired without tearing-off old surface thereby reducing waste and further overburdening landfills.
- Many of the elastomeric coatings are Energy Star® compliant and may have earned Cool Roof ratings due to their high reflectivity of harmful UV rays.
- Minimize energy consumption by controlling temperature extremes of heat loss and gain through the roof system.
SPF ROOFING FAQs
SPF excels in areas where:
- Additional insulation is desired
- The roof substrate has many penetrations
- The roof deck is an unusual shape or configuration
- Slope must be added to provide positive drainage
