Walk-through
We review drainage and details with you and clean up the site.
What affects the estimate
We do not post price ranges because they would not be honest without seeing your roof. These are the things that move the number for this kind of work:
- Existing system and how many layers are on the roof
- Wetness in insulation, which a moisture check can reveal
- Slope, ponding and drain or scupper condition
- Number of penetrations, curbs and parapet details
- Whether a coating, overlay or full replacement is appropriate

New Flat Roof: common questions
Why does water pool on my flat roof?
Usually slope or drain issues. Ponding can shorten membrane life, so fixing drainage is part of a good scope.
Which system is right?
It depends on sun exposure, traffic, budget and building. We recommend after inspecting.
