Residential TPO flat roofs
Plenty of houses have a section that is too flat for shingles: a porch, an addition, a carport or a garage. AGX installs TPO membrane roofing on those residential flat and low-slope roofs.
Where a flat roof needs TPO
- Flat roofs over additions and sunrooms
- Covered porches and patio roofs
- Carports and attached garages with a low slope
- Low-slope sections tied into a pitched shingle roof
Shingles shed water by overlapping, which only works when the roof is steep enough for water to run off quickly. On a flat or nearly flat section, water sits, gets pushed under the overlaps, and finds its way in. A membrane has no overlaps for water to get under.
What TPO is
TPO (thermoplastic polyolefin) is a single-ply roofing membrane that comes in wide sheets. The seams between sheets are joined with hot air, which fuses them into one continuous surface instead of relying on adhesive or overlapping pieces.
Where a flat section meets a shingled roof, the transition and flashing between the two is where most problems start, so that detail matters as much as the membrane itself.
Questions homeowners ask
Is TPO only for commercial buildings?
It is common on commercial roofs, and it also works on the flat and low-slope parts of houses. AGX installs it on residential roofs.
What color is TPO?
It is usually white or light gray, so it reflects much of the summer sun rather than soaking it up.
What if the rest of my roof needs work too?
Mention it when you call. A flat section and a pitched shingle roof can be looked at on the same visit and covered in one estimate.
