Built-up roofing, or tar and gravel, is the century-old system still protecting Lewisville buildings that were roofed before single-ply existed, and still a legitimate choice for the right structure.
Built-up roofing earns its keep through redundancy: alternating layers of bitumen and reinforcing felt, topped with gravel that shields the assembly from UV and foot traffic. On Lewisville buildings, an existing BUR roof often deserves maintenance and restoration rather than replacement, because the same mass that makes it heavy makes it durable.

Lewisville storm exposure and aging BUR
The hail numbers set the inspection schedule. Hail an inch or larger has struck within 7 miles of Lewisville on 34 days since 2006, including 14 days at golf-ball size or bigger, and the peak was 3.0 inches on June 11, 2023. Gravel surfacing absorbs a lot of that, but seams, flashings and drains still take hits that walking the roof can miss, so we document each one.
Lewisville grew mostly between 1980 and 2009, the era that built 63 percent of its homes, so many roofs across the city are old enough that restoration versus replacement is a live question. If the roof is not a fit for restoration, the inspection says so. Owners with buildings in The Colony or Lake Dallas get the same crews and the same written findings across Denton County.

Common questions about built-up roofing (bur) in Lewisville
My Lewisville 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.
Do you install this on shops and outbuildings near Lewisville?
Yes. Barns, workshops, and outbuildings are first-class projects out here, not afterthoughts, and the material conversation (usually metal-forward) covers them alongside the house.
