Flat roof leaks hide: water travels between membrane and decking before it surfaces inside, often far from the entry point. Flat roof leak repair in Lewisville starts with moisture tracing, not guesswork.

A flat roof leak in Lewisville gets traced before it gets patched. Water on a low-slope roof can travel a long way from where it enters to where it drips, so we find the actual entry point first. Then the repair gets matched to the membrane: TPO, EPDM, PVC, and mod-bit each repair differently, and Lewisville buildings run all of them. The investigation is documented with photos, and the estimate is free and in writing. We never waive a deductible, since Texas law forbids it, and we are not public adjusters.
Flat Roof Leaks and Lewisville Hail
On a flat roof, hail damage often becomes a leak weeks or months after the storm. Lewisville has seen 1-inch or larger hail within 7 miles on 34 days since 2006, and 14 of those days produced golf-ball-size stones or larger. A membrane can take a hit that looks like nothing more than a scuff, then open up as it expands and contracts through the following seasons. When we chase a leak on a Lewisville flat roof, hail history is one of the first things we consider.
The largest hail on record near the city was 3.0 inches on June 11, 2023, and 1-inch hail has fallen in 15 of the last 20 years. That frequency means a flat roof here may carry impact damage from more than one storm, and the leak you see today could come from any of them. Our leak crews cover Lewisville along with Lake Dallas and The Colony in Denton County, and each call ends with photos showing where the water got in and how it was sealed.

We don't waive deductibles; nobody legally can. Texas law requires
homeowners to pay their insurance deductible (Tex. Ins. Code ch. 707). If a roofer offers
to "cover" or "absorb" yours, walk away. It puts your claim at risk and may be a felony
for the contractor.
We document damage, provide repair and replacement estimates, and meet your
adjuster on-site to answer construction questions. We are not a public adjuster
and do not interpret your insurance policy or negotiate claim value on your behalf.
Common questions about flat roof leak repair in Lewisville
Why does my flat roof leak keep coming back?
Usually because the visible symptom got patched while the actual entry point kept feeding water into the assembly. Moisture tracing finds the source; that is the repair that lasts.
Can ponding water cause leaks?
Standing water accelerates membrane wear and finds every weakness. Persistent ponding is a drainage problem worth solving, not just a symptom to patch around.
Do you repair all flat roof types in Lewisville?
TPO, EPDM, PVC, modified bitumen, and built-up systems, each with the repair method the system calls for.
How fast can you get to Lewisville for this work?
Scheduled windows run reliably. Crews route the ring on planned days rather than same-hour dispatch, with genuine emergencies jumping the queue regardless of geography. You'll get honest timing on the first call.
