Polyurethane Foam
Roofing Systems...
Polyurethane foam roof systems are created
by spraying the foam in liquid condition onto the roof
where it immediately rises and hardens. The results
is a non-porous foam about 3/4" thick with a density
of approximately 3 lbs./sq .ft. There are no seams or
laps where leaks often develop.
This system weighs approximately 100 pounds per 100
square foot. Other roof systems can weigh as much as
1,000 pounds per square foot. Excessive weight can cause
the structural integrity of a roof system to fail -
especially under excess ponding water conditions.
This roof is perfect for waterproofing needs. The foam
acts as a barrier, preventing moisture from seeping
into the building. Water ponding is a well known problem
on a majority of roofs and can be eliminated by building
up low areas with foam to help alleviate ponding water.
This system has an R-value of 7.14 per 1 inch thickness.
Thus providing more thermal resistance. Because the
insulation is such an asset - it will produce savings
on your electric bills of 30% or greater. You will end
up having the roof not only pay for itself but produce
dividends!
