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 Allen starts with moisture tracing, not guesswork.

Pick the door that matches your situation. It routes you to the right person on the team, and every path starts with a free, documented look at the roof.
Texas law requires homeowners to pay their insurance deductible.
Cedar Crest does not waive or absorb deductibles. If anyone offers to, walk away.

Water on a flat roof rarely enters where it drips, so the first job on an Allen leak call is tracing the path back to the actual opening. Then the repair gets matched to the membrane. TPO, EPDM, PVC, and mod-bit each repair differently, and Allen buildings run all of them. You receive photos of the source and the fix, plus a free written estimate before any work starts. If the leak is storm-related, we answer construction questions for your adjuster but do not act as a public adjuster, and we never waive a deductible, which Texas law does not allow.
Flat Roof Leaks After Allen Hail
Low-slope membranes take hail differently than shingles do, and Allen gives them plenty of exposure. Within 6 miles of the city, 27 days since 2006 brought hail an inch or larger, 12 brought golf-ball stones or bigger, and March 24, 2019 set the local high at 4.5 inches. A bruised or fractured membrane may not leak right away, which is why flat roof leaks often surface weeks after the storm that caused them. With that size of hail recorded in 13 of the last 20 years, we check the whole field, not only the wet spot.
Homes built from 1980 through 2009 make up 66 percent of Allen’s housing, and commercial buildings from that same era can show seam and flashing wear that hail exposes. Flat roof leak calls in Collin County’s Lucas and nearby Plano go to the same crews.

How old Allen homes are

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 Allen
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 Allen?
TPO, EPDM, PVC, modified bitumen, and built-up systems, each with the repair method the system calls for.
Will this work void our builder's warranty in Allen?
Properly documented work doesn't, and our written findings and scopes are built to keep your builder-warranty file intact. What actually endangers coverage is undocumented storm patching, which we don't do.
