Repairing
roofs with Sprayed Foam.
SPF
roofs are considerably easier to maintain and repair than other
roofing systems. While Buit-Up roofs and single-plys must be removed
and replaced after their usable lives; repairing and recoating
an SPF roof enables it to last indefinitely.
Replacing
an Existing Roofing System
Because
of its light weight, Sprayed Polyurethane Foam can be applied
over already existing roof installations. It can be applied directly
over asphalt, shingles, built-up roofs, clay tile, concrete, metal,
and wood. This saves the need for tear-off, reducing the amount
of time, disruption to the business, even the debris in landfills.
The roof has to be properly prepared by cleaning off any loose
debris and aggregate, and by making sure that it is completely
free of moisture.
Repairing
a SPF Roof
When
a foam roof gets minor mechanically induced damage from equipment
or personnel, repairing the roof can be done with a caulking gun.
Larger penetrations into the roof can be temporarily sealed with
caulking as well, but it is recommended that the contractor should
permanently seal the area with a new layer of topcoat.
SPF
roofs can sometimes develop blisters, the most common cause of
which is due to the presence of moisture. The majority of blisters
do not pose a threat to the integrity of the roofing system. Unneccesary
repairs to them can result in leaks and premature roof problems.
If repairs are warranted, it should be left to the roofing contractor
to properly repair them.
