Commercial and Flat Roofing
Flat Roof Installation
Flat roofs shed water slowly, so drainage, seams and insulation matter more than anywhere. We design the slope, insulation and membrane as a system and install it so water leaves the roof instead of waiting on it.

Questions
About flat roof installation
Why does water pond on my flat roof?
Sagging decks, poor slope and clogged drains cause ponding. We look at the cause before choosing a fix.
Which membrane is best?
It depends on the building, the budget and the roof's exposure. We compare TPO, EPDM and modified bitumen with you.
Can a flat roof be repaired?
Often yes, with patches and seam repairs, but widespread damage may call for replacement.
