Tar & gravel — inspecting NM's classic built-up roof.
Multiple layers of asphalt-saturated felt topped with gravel — the roof many NM buildings grew up under. Our inspection strips a small test area to core the layers and score remaining service life.
The straight story
- Gravel-coverage mapping — bare-asphalt exposure indicates UV failure.
- Optional core sample: layer count, saturation, remaining ply strength.
- Structural review — tar-and-gravel is heavy, verify before overlay.
- Recoat-vs-tear-off scope with load implications documented.

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.

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.
