Why It Matters

Low-slope areas need roofing systems designed to handle slower drainage. Torch down modified roofing is one type of system used for those conditions.

Common Problems

Common problems include poor seams, unsafe installation practices, ponding water, bad edge details, and using the wrong material for the slope or deck condition.

Building Codes & Industry Standards

Torch down modified roofing should follow manufacturer instructions, local fire and safety requirements, and applicable low-slope roofing standards.
