Torch down roofing for flat roofs, garages, porches and extensions.
About the Service
Flat Roof Installation & Repair
Flat and low-slope roofs need a different system than pitched roofs. We install torch-down modified bitumen roofing — a proven, durable system that creates a seamless, watertight seal. It’s the right choice for garages, extensions, porches, and commercial properties.
Common signs your flat roof needs attention:
- Standing water or puddles after rain
- Bubbling or blistering on the surface
- Visible cracks or splits in the membrane
- Interior leaks after heavy rain
- Old or failing rubber membrane
- Roof over 15 years old
