TPO: Thermoplastic Olefin or Polyolefin
TPO Roofing membranes are single-ply roof membranes
constructed from ethylene propylene rubber. They are
designed to combine the durability of rubber with the proven
performance of hot-air weldable seams. They have been tested
as having excellent resistance to ozone, are algae-resistant,
environmentally friendly and safe to install. The material's
manufacturers are so confident in properly welded seams that
the material is sometimes advertised as a monolithic
(seamless) roof. Seam strengths are reportedly 3 to 4 times
those of EPDM's adhesive and tape seams. TPO is highly
resistant to tears, impacts, and punctures with good flexibility
to allow for building movement. TPO's are available in white,
light gray, and black with thicknesses of either 45 mils (.045")
or 60 mils (.060"). The width of the membrane depends on the
manufacturer but they usually come in widths of six to
six-and-a-half feet and are one-hundred feet in length.

TPO Roofing membranes are installed fully-adhered,
mechanically-attached or ballasted. Fully-adhered means that
the roof is "glued" to the substrate using a special adhesive.
What actually happens is the glue creates a chemical bond
with the membrane. Ballasted simply means the membrane is
loose laid over the top of the roof, sealed at all penetrations
and around the perimeter, and then a ballast is put on it to
hold it in place. Ballast usually consists of smooth, round,
river rock 2" - 3" in diameter and is applied at a rate of 1,000 to
1,200 pounds per roof square (100 sq. ft.). Sometimes concrete
pavers are used in their place. These average 20 pounds per
square foot. Mechanically-attached membranes are those that
use some type of special screw-type fastener to secure it. The
type of fastener will depend on the type of substrate but all
fasteners are generally screw-type fasteners.

TPO Roofing is also known for its resistance to grease
and ponding water so if you own a restaurant or a
roof which holds a lot of water TPO is a very wise
choice.

TPO Roofing is also known for its reflective Qualities
which makes it a great choice if you want to cut your
air conditioning costs!
