Flat roofing and TPO in Bryan and College Station

Flat roofs are common on commercial and industrial buildings and on contemporary homes with low or minimal slope. If your building already has EPDM or PVC, we inspect it and tell you in writing what we find.

• TPO Thermoplastic polyolefin, a reflective single ply membrane with welded seams. This is the flat system we install.
• EPDM A synthetic rubber membrane, usually black.
• PVC Polyvinyl chloride, a plastic based membrane with chemical resistance.

TPO is reflective, so it sends much of the sun back off the roof.

The weak points on a flat roof are water that does not leave and the places the membrane stops: ponding that has not drained within the expected window, the seams, punctures, and the terminations and flashings at every curb and edge.

A TPO roof is only as good as its seams and its edges, so those get the attention: welded seams, and flashing at every curb, penetration and edge.

On an inspection we check seam integrity, punctures, ponding, and the terminations and flashings, and photograph what we find. A sound membrane can be protected with a coating, which has its own page.

• Debris and standing water Cleared regularly, because a flat roof does not shed what lands on it.
• Seams and flashing Inspected on a schedule, since that is where a membrane opens up.
• Punctures and tears Dealt with promptly, before water reaches the deck.
