TPO — what to inspect on NM's most common flat-roof system.
White single-ply membrane. Reflects sun, sheds monsoon water, gives 20–30 years when spec'd and installed correctly. Our inspection focuses on seam welds, T-joint patches, and flashing terminations — where TPO actually fails.
The straight story
- Seam-weld probe test on every heat-welded joint we can reach.
- T-joint patch presence and adhesion check.
- Ponding-water mapping with slope math.
- Manufacturer-warranty registration audit (often expired or never filed).

Matched from a contracted NM roofing bench.
I maintain contracts and working relationships with 15+ NM roofing companies across small, mid-size, and regional tiers. After the scope is written, I send it to 2–3 bench contractors matched to your roof's complexity, warranty needs, and timeline. Matched by fit, not by marketing spend.
Inspect. Specify. Match. Protect.
One inspector, four deliverables. You get an honest diagnosis, a written specification, a matched short list from our contracted and vetted NM contractor bench, and a second set of eyes on their bids and their work — with no financial interest in the outcome.

Roof Doctor NM is an independent third party. We do not sell, install, or repair roofs — diagnosis comes first. When a matched bench contractor is hired, they may pay a flat, disclosed referral fee. The fee is fixed and disclosed to you in writing before you pick a contractor, so it cannot change what we recommend. Homeowner inspection fees remain our primary revenue.
