What torch-down roofing actually is
Torch-down roofing is a form of modified bitumen. Rolls of reinforced asphalt membrane are fused at the seams to create a continuous surface over a prepared low-slope roof assembly. It is common on Philadelphia rowhomes, rear additions and small commercial buildings.
The material can handle normal roof movement and weather well, but installation is detail-sensitive. Wall transitions, vent pipes, drains, scuppers, skylights and adjoining roofs are frequent leak points when they are not integrated correctly.
When it may be a good fit
Before recommending any system, we look for trapped moisture, soft decking, poor drainage, incompatible materials and too many existing layers. Depending on those conditions, a repair, tear-off, recover system, EPDM or TPO may make more sense.
Safety is part of the roofing system
Open-flame work must never be treated casually. The roof construction, nearby combustible materials, access and weather all affect whether a torch-applied product is appropriate. The project plan should include site-specific fire precautions and a different application method where torch use is not suitable.
What a complete proposal should address
- Existing layers and deck condition
- Insulation and slope toward drains or scuppers
- Base sheet and cap-sheet assembly
- Parapet, party-wall and edge details
- Flashing at vents, skylights and rooftop equipment
- Removal, cleanup and final inspection
