Our Torch On
ROOFING Process

We start by evaluating your current roof or new construction plans, ensuring a proper substrate and design for torch-on installation. - Preparation & Repair
Before installing the torch-on membrane, we address any issues like ponding, damaged insulation, or structural concerns. - Membrane Installation
Our certified installers apply multiple layers of SBS-modified bitumen and seal it with heat for a seamless, watertight finish. - Final Inspection
