Torch-down roofing is a type of flat roofing system made from modified bitumen sheets that are applied using direct heat from a torch. This process creates a waterproof, durable membrane ideal for flat or low-slope roofs. The installation cost per square foot typically ranges from $5 to $8, though this can vary depending on the region, roof complexity, and contractor experience. Torch-down roofs are favored for their resilience against weather and UV rays, but installation requires skill to avoid burns, improper adhesion, or damage to underlying materials. Homeowners should be aware that this roofing method works best on decks that are completely dry and clean during installation, as moisture or debris can cause problems later.
If you want to check your existing torch-down roof, a simple visual inspection can reveal bubbling, cracking, or soft spots, which could indicate underlying issues. Ensure there’s no smell of asphalt or persistent water pooling after rain, as these signs mean it may be time for professional evaluation. Safe DIY checks include looking for loose or splitting seams, but avoid walking on the roof too much to prevent damage. When calling a roofer, ask how they handle torch-down installations in your climate type and what warranty coverage they provide, including labor and material specifics. Requesting a demonstration of their torch technique and asking for references on similar projects can also help ensure quality work. Remember that warranties often depend on proper installation, so choosing a knowledgeable contractor is key to long-term success.
