- In comparison to conventional roofing, the SPF Cool
roofing System is the most energy efficient system
available. You can typically expect to recover he
entire cost of your new foam roof over a short period
of time. Spray polyurethane foam is the best
insulating material available today. Its closed cell
nature results in the highest R-value per inch of any
insulation material. The white reflective top coat also
makes it the coolest under the direct sunlight (see
table to the right). Click here to go to Energy Star's

- A major cause of heat gain is the conductive
heat gain through your roof system. The
drawing to the right illustrates the advantages
of SPF roofing system in reducing heat gain.
- Spray Polyurethane Foam's monolithic nature provides superior waterproofing when compared
to conventional BUR or single ply systems. This is because those systems are layered and/or
contain seams and when compromised will allow water to travel extensively throughout the
system. The foam roofing system is spray applied to all penetrations, curbs, roof-mounted
HVAC units and parapets in a seamless application which eliminates a common source of
leaks. A leak in the membrane of a single-ply or BUR roof allows the spreading of water which
can allow multiple leaks into your building. The SPF system has no seams, cracks or
fasteners through which water can penetrate through. In the event a hole is punched through
the SPF system, the water movement is restricted to that hole.
- SPF Cool Roofing Systems are simple to maintain. Minor damage is readily identifiable and
easily repairable.
- SPF Cool Roofing Systems can be installed directly over most existing roof surfaces
eliminating the need for costly and disruptive tear-off procedures. No heavy tar fumes.
- SPF Cool Roofing Systems are versatile. The SPF system has the ability to correct
depressions and poor drainage by building up the foam in the ponds on the roof and creating
drainage crickets that facilitate positive drainage. The weight load is very low compared with
conventional BUR systems while still providing outstanding strength to the roof.
