Expert Solutions for Flat Roof Leaks and Damage

Flat Roof Repairs and installs

We address issues with various materials. EPDM (Ethylene Propylene Diene Monomer) repairs often involve patching leaks with EPDM roofing material, which may include applying a new layer or using a liquid rubber sealant for minor leaks. TPO (Thermoplastic Olefin) repairs typically involve heat welding new TPO patches over damaged areas to ensure durability and energy efficiency. Modified bitumen repairs often involve applying a new layer of modified bitumen—a blend of asphalt and modifiers—to damaged sections using either torch-down or cold adhesive methods.

Reliable Metal Roof Panel Replacement and Corrosion Treatment
