Materials for Commercial Roofs
The majority of
commercial roofs, or “flat roofs,” consist of tar and gravel.
Tar and gravel is used on roofs with a pitch of no more than 3 inches
rise to 12 inches run. This roof is installed by alternating layers of
heavy roofing felt and hot asphalt or tar. The final product is coated
with a mineral such as gravel. The roof is rated by how many layers are
applied, usually 3 to 5 layers. As with all flat roofs, this is not
recommended for areas with high rainfall or snowfall.
Other materials used
for commercial roofs are:
-
Modified
bitumen roofing -
Similar to the tar and gravel roof, this roof adds layers of
polyester or fiberglass with bitumen. These additional layers add
strength and resistance to this type of roof. As with all flat roofs,
this is not recommended for areas with high rainfall or snowfall.
-
EPDM rubber
roofing - The ethylene propylene
diene monomer (EPDM) creates a single layer rubberized roof that is long
lasting, UV resistant, and does not require a mineral coating (making
the roof lighter than tar and gravel roofs). A rigid insulation is a
common underlay for this type of roof. As with all flat roofs, this is
not recommended for areas with high rainfall or snowfall.
-
Roll
roofing - This low
cost roofing product is made from materials similar to asphalt shingles,
but has a relatively short life--less than 10 years--because it is a
single-ply roof. Roll roofing is commonly known as 90-pound felt, since
one roll covering 100 square feet weighs around 90 pounds. As with all
flat roofs, this is not recommended for areas with high rainfall or
snowfall.
-
PVC Membrane -
A roof membrane composed of only one layer of material, polyvinyl
chloride. PVC roofs are designed to withstand “ponding” water. Moisture
will not pass through the PVC membrane, which is welded together with
hot air (no open flame) to eliminate all seams. Furthermore, PVC roofing
systems reflect nearly 90% of the heat of the sun that would normally
come through a roof, lowering energy costs substantially, especially in
high-heat areas such as the southwestern United States. PVC roofing
systems have been known to become brittle over time.
-
Spray Foam Roofing
-
Description: SPF is sprayed polyurethane foam, a closed cell roofing and
insulation material that is rapidly gaining market share in today’s
construction industry. Because it is spray applied, it forms a seamless
barrier to the weather. They can be applied to vertical surfaces such as
parapet walls thus eliminating seams and cold joints (the main source of
roof leaks). SPF has no fasteners. Fasteners puncture decks,
contributing to premature failure, create thermal bridging, reducing
insulation value and tend to pull-out under wind load.
