Flat Roof Repair

We sealed over this entire commercial flat roof. There will no longer be any water leaks here.

Replace flat roofing system

By simply installing a new modified rubber patch over the threshold of these connecting roofs where the underlayment was becoming detached, we stopped all current and future leaks in this potentially troublesome area.
