Modified Bitumen & Built-Up Roofing in DFW
Multi-ply asphalt systems for durable low-slope roofs.
Modified bitumen (mod-bit) and built-up roofing (BUR) are multi-ply, asphalt-based low-slope systems valued for durability, redundancy and resistance to foot traffic. Mod-bit typically lasts 15–20 years and BUR 15–30. They're a solid choice for roofs with heavy rooftop service traffic. T.A.P. installs and repairs mod-bit and built-up roofs across Dallas–Fort Worth.

Why mod-bit and built-up roofing
Multi-ply asphalt systems build in redundancy — several reinforced layers instead of one membrane — which makes them tough and forgiving of the foot traffic that HVAC and other rooftop service brings. A granulated or reflective cap sheet protects against UV.
When a mod-bit or BUR roof ages but is still sound, a restoration coating can extend it for far less than replacement. See coating vs replacement or typical cost.
