Spray Foam Roofing
Spray
Polyurethane Foam has been used as a roofing and insulation
material for over 40 years. It was once considered to just
be an alternative to built-up roofing; foam roofing now
protects a wide range of buildings and can be used in all
types of roofing situations, from traditional flat roofs to
unusual designs. There are numerous benefits that spray foam
roofing provides. The two main benefits are
waterproofing/leak prevention and insulation value.
Foam roofing systems can be applied quickly with very little
and sometimes no disruption to the facilities. Spray
foam roofing has proven to be dependable and very
affordable.
Benefits
No seams or joints
Can be used on any surface and any roof shape
Lightweight (around 50lbs. per square)
Foam roofing offers the best insulating properties available
for commercial construction
Require minimum maintenance
Weather resistant
Durable/long lasting with indefinite lifespan
Replacing an
Existing Roof
In most cases, spray foam roofing does not require removal
of the existing roof. Once the roof is cleaned of
loose debris and free of any moisture, sprayed polyurethane
foam can be directly applied over asphalt, shingles,
built-up roofs, clay tile, concrete, metal, and wood.

How it works
Sprayed Polyurethane Foam is applied as a liquid
using plural-component spray equipment to fill
cracks and crevices. It then expands approximately
30 times its original liquid volume to form a hard,
closed cell monolithic roof surface. The
Polyurethane Foam dries within seconds after applied
to the roof surface. Its expansion results in a
weather tight roofing membrane that is fully adhered
to the substrate. Because of polyurethane's
lightweight it adds little additional weight to the
structure and is often used in remedial
applications. Polyurethane Foam has a history of
more than 35 years as a maintainable roofing medium.
Polyurethane Foam adds excellent insulation value to
the structure and utility bills can reflect the
difference.
Once the SPF has been applied to the proper
thickness and finish specifications, a protective
layer of elastomeric coating or gravel is applied.
This protective layer produces a durable weather
resistant surface and that can be walked on for
normal maintenance. |
