TPO roofing in San Jose

TPO is a single ply membrane, meaning one layer of manufactured sheet material covers the roof instead of a stack of layers. TPO membrane sheets are rolled out over the prepared roof, overlapped, and welded together with heat at the seams. The membrane is typically white or light in color, which reflects sunlight.

1. 01Roof assessment. We check the existing roof, deck and insulation.
2. 02Preparation. Damaged areas are repaired, and the old roof is removed or prepared as needed.
3. 03Insulation. Where needed, insulation is installed over the deck.
4. 04Membrane. TPO sheets are laid out, attached and overlapped.
5. 05Seams and flashing. Seams are heat welded, and edges, walls, drains and penetrations are flashed.
6. 06Final walkthrough. We review the finished roof with you and hand over warranty paperwork in writing.

• The current roof leaks in several places or has been patched many times
• Moisture has soaked into the insulation
• The surface is cracked, blistered or worn through
• Water ponds after rain (the cause has to be found and fixed first)

Some of these point to a coating instead, so we check the roof before recommending a system.

Like any membrane, TPO can be punctured by dropped tools or sharp debris, and a seam is only as good as the welding behind it, so the quality of the installation matters. TPO also does not fix a drainage problem: ponding water and wet insulation have to be dealt with first.
