GoulenCo Roofing
Torch-Down Flat Roofing
Modified bitumen torch-down systems for garages, additions, and low-slope residential roofs that need proven waterproofing.

What this service is for
Torch-down (modified bitumen) flat and low-slope roofing for residential South Bay sections.
Where torch-down fits
Torch-down modified bitumen is a staple on many South Bay residential flat and low-slope sections. When installed with correct overlaps, base flashings, and drainage, it is a durable choice for garages, porches, and addition roofs.
It is not a substitute for fixing chronic ponding — water that sits will stress any membrane. We look at slope and drains as part of the scope.
Repair or replace
Small blister or seam repairs can buy time. When the membrane is brittle, widely cracked, or leaking at multiple details, a full torch-down reroof is usually the cleaner path.
Financing where feasible
Financing may be available where the project and credit fit — ask during your estimate.
FAQ
- Is torch-down the same as modified bitumen?
- Torch-down typically refers to modified bitumen sheets installed with heat. Exact products vary; what matters is correct detailing, adhesion or welding method, and drainage.
- How long does torch-down last?
- Service life depends on UV exposure, foot traffic, drainage, and installation quality. We inspect condition rather than promising a fixed year count that cannot be guaranteed for every roof.
