Built-up roofing, or tar and gravel, is the century-old system still protecting Flower Mound buildings that were roofed before single-ply existed, and still a legitimate choice for the right structure.
A built-up roof is made of redundant layers: alternating bitumen and reinforcing felts, finished with gravel that shields the assembly from UV and foot traffic. When we assess an existing BUR in Flower Mound, maintenance and restoration often make more sense than replacement, because the mass and redundancy that made it heavy also made it durable.
Building owners get a free written estimate and an inspection documented with photos. We never waive deductibles, which Texas law prohibits, and we are not a public adjuster. Our assessment covers whether BUR still fits the building and its budget.
Gravel, Felts, and Flower Mound Hail
The gravel surfacing on a BUR does real work given Flower Mound’s hail history. Within 7 miles of town, hail an inch or larger has fallen on 34 days since 2006, and 15 of those days produced golf-ball size stones or bigger. On a layered roof, a hit that gets past the gravel still has to get through several plies, which is why we look below the surface instead of judging damage by the gravel alone.
Flower Mound is not an old town: the median home dates to 1997 and only 5 percent of housing predates 1980. On a sound built-up roof, restoration keeps that redundancy working instead of throwing it away. We service commercial roofs across Denton County, including Highland Village and Double Oak.

Common questions about built-up roofing (bur) in Flower Mound
My Flower Mound building has tar-and-gravel. Replace it?
Not automatically. Sound BUR restores and maintains well; its redundancy is real. A moisture survey tells you whether the assembly beneath the gravel is dry, and that answer decides.
Why did BUR fall out of fashion?
Weight, installation labor, and odor during application. Single-ply installs faster and lighter. Neither of those points makes an existing sound BUR roof bad.
Is upgrading from builder-grade shingles worth it in Flower Mound?
Usually at the first replacement or claim: Class 4 impact-rated systems earn many Texas carriers' premium discounts, and newer communities' HOA standards generally approve them easily. The math works hardest on homes facing decades of DFW hail.
How often does hail hit Flower Mound?
