What is a torch-down roof?

A torch-down roof is a modified bitumen low-slope system in which asphalt-based membrane sheets are heat-applied to the roof, melting the underside so it bonds to the layer beneath, with heat-welded seams forming a continuous surface. The polymer-modified asphalt adds flexibility and durability. Atlas Roofing San Diego installs torch-down roofs with in-house crews experienced in modified bitumen.

Is torch-down roofing durable in San Diego?

Yes. The polymer-modified asphalt handles temperature swings and the elements, and the multi-ply construction gives it toughness on low-slope roofs. Like any flat roof, it depends on proper drainage to handle winter rains. Installation by an experienced crew is key, because the method uses controlled heat. Atlas Roofing San Diego installs torch-down with experienced in-house crews.

How much does a torch-down roof replacement cost in San Diego?

Cost depends on the roof's size, the deck condition, the drainage work, and the specific system. Because those variables differ on every roof, Atlas Roofing San Diego provides a free estimate after inspecting the roof rather than a flat rate or a per-square figure. A repair may be an option if the damage is isolated.
