The challenge

Water pooled for days around the rear scupper, and the top-floor unit had two ceiling leaks in one year.

What we did

  1. Core cuts found wet insulation across 30 percent of the roof.

  2. Designed tapered polyiso with crickets to move water to a new enlarged scupper.

  3. Coordinated deck removal and reinstall on new sleepers with the association's carpenter.

  4. Heat-welded TPO with probe-tested seams and new copper edge metal.

The result

Water drains within hours after storms, and the association received a 20-year system warranty certificate.

They gave our three-person board a clear scope and a schedule, then did exactly what they said.
