Modified Bitumen Flat Roofing in DFW: Cost and Repair Guide
Modified bitumen flat roofing is one of the most common ways to cover the low-slope sections of a Dallas-Fort Worth home, from porch roofs and patio covers to garage additions and flat areas behind a parapet wall. It is an asphalt-based membrane that comes in rolled sheets and holds up well to foot traffic and North Texas heat when it is installed with proper drainage. This guide explains how modified bitumen works, how long it lasts, what drives the cost of a new flat roof, and when repair makes more sense than replacement.
