Three roofers wanted $32k after the June hailstorm. Roof Doctor NM walked the roof, took 84 photos, and said the hail was cosmetic. Saved me from a fraudulent claim.

Nob Hill flat-roof TPO over a 1940s adobe
1940s adobe with two failed modified bitumen roofs and chronic ponding water on the southwest quadrant. Previous coatings had blistered. AC bills were brutal.

Roof area

Duration

System
Carlisle Sure-Weld 60-mil White TPO
The challenge
What we walked into.
1940s adobe with two failed modified bitumen roofs and chronic ponding water on the southwest quadrant. Previous coatings had blistered. AC bills were brutal.
- Two failed modbit layers, blistered coating
- Standing water 4+ days after rain
- Attic temps over 140°F at peak summer
The approach
How we worked it.
- 1Removed two layers of failed modbit down to the original tongue-and-groove decking.
- 2Installed tapered ISO insulation to break up the ponding low spot — three crickets total.
- 3Re-pitched scuppers and added a secondary overflow scupper per current code.
- 4Mechanically fastened 60-mil white TPO with 25-year manufacturer warranty.
The result
Where it landed.
Confirmed zero standing water 48 hours after the heaviest July 2024 storm. Owner reports a 19% drop in summer cooling cost vs. 2023. Roof qualifies for PNM cool-roof rebate ($380 issued).
- 60-mil reflective white TPO
- Re-pitched drainage with tapered ISO
- PNM cool-roof rebate qualified
"Three other roofers wanted to skip the ponding fix and just lay new membrane. Roof Doctor NM explained why that voids the warranty — the contractor re-pitched the scuppers first. Bills dropped 19% this summer."
