Chimney flashing spec — cricket, step, counter.
Chimneys are the #1 leak source on pitched NM roofs. The fix is code-correct step + counter flashing with a cricket on the uphill side of any chimney wider than 30". We spec it; a NM contractor installs it.
The straight story
- Step + counter-flashing spec with metal gauge and material called out.
- Cricket required per IRC when chimney width exceeds 30".
- Sealant type and fastener spec — no 'contractor's choice' loopholes.
- Written scope any NM chimney or roofing contractor can bid.

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.

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.
