Flashing, Chimney & Skylight Repair in Denton: The Leak Points That Matter Most

Denton sits on the Blackland Prairie where expansive black clay soil shifts with every wet and dry cycle, and that movement works on roof penetrations year after year. Around the courthouse square, the 1890s Victorian and Queen Anne homes with steep gables hide original brick chimneys that need custom flashing, not a caulk-and-pray patch. Out in Mayhill, Corinth and Argyle, the two-story brick-and-stone subdivision homes have skylights and furnace flues that leak at the curb and the boot. Flashing, Chimney & Skylight Repair in Denton is the work we do most, because flashing is the number one leak point on any roof in this county. We bend metal in-house, so the counterflashing, step flashing and skylight curbs fit your chimney and your panel profile, not a shelf part. If water is already staining a ceiling, start with our metal roof leak repair page and we will trace it to the penetration before we quote anything.

Why Denton Roofs Leak at Chimneys, Skylights and Valleys First

North Texas throws hail, spring wind and long UV summers at every roof, but the failures we see are concentrated at transitions. A brick chimney on a 1920s bungalow in Evers Park has a masonry face that moves differently than the roof deck, so the flashing has to float and shed, not seal rigid. Skylights on 1980s and 1990s homes in Flower Mound and Lake Dallas were often installed with a nailed curb and a bead of mastic that dried out a decade ago. Valleys on the low-pitch 1960s ranches across Southridge collect oak leaves and pecans, then hold water against the metal edge. We fix the detail, not just the stain on the drywall.

• We remove the old flashing and inspect the deck and underlayment before anything new goes on.
• We fabricate step flashing, counterflashing and skylight curbs from 24-gauge or copper to match your roof.
• We cut a proper reglet into brick chimneys and seal it with urethane, not surface caulk.
• We rework valley metal and dormer transitions where panel edges meet shingle or masonry.
• We water-test the repair before we leave so you know the leak is closed.

Every repair ends with a photo record of the flashing detail, which helps if you file a hail or wind claim later.

Key info: A homeowner on Bell Avenue had a ceiling stain that three roofers blamed on the shingles. The actual leak was a rusted chimney cricket that had been caulked twice. We rebuilt the cricket and counterflashing in half a day, and the stain stopped spreading after the next storm.

For the official word on when a roofing permit is required in the city, check the City of Denton building department before any repair that changes the roof structure.

How We Repair Flashing, Chimneys and Skylights on Denton County Roofs

We start on the roof, not on the phone. A flashing leak rarely shows itself where the water lands, so we inspect the whole penetration zone and the attic side when access allows. On standing seam and stone-coated steel roofs in Argyle and Sanger, we use manufacturer-compatible closures and gaskets so the repair does not void the panel warranty. On older corrugated and ribbed roofs, we replace the butyl washer screws around the penetration at the same time, because a flashing repair over tired fasteners will leak again.

1. We inspect the chimney, skylight, valley, dormer or brick transition and photograph the failure.
2. We remove the failed flashing, mastic or failed sealant and check the deck for rot.
3. We measure and bend new flashing in-house to fit the penetration and the panel profile.
4. We install with proper laps, reglets and fasteners, then seal with urethane or butyl as the detail requires.
5. We water-test and show you the finished detail before we pack up.

If the inspection turns up storm damage beyond the flashing, we document it for your insurance file and handle the repair under our storm and wind damage repair service.

Local example: A two-story home in Corinth had a skylight that dripped only during hard spring storms. The curb was fine; the leak was the step flashing where the skylight met a sidewall, installed with too few fasteners. We rebuilt the sidewall flashing and replaced the skylight seal in one visit.

Repair Approaches We Use on Denton Chimneys, Skylights and Valleys

The right approach depends on the roof material, the age of the penetration and how the original installer detailed it. Here is how we match the method to the job.

We tell you which approach your roof needs after the inspection, and we do not sell a full re-roof when a flashing repair will close the leak.

Flashing, Chimney & Skylight Repair Cost in Denton: What to Expect

Most single-penetration flashing repairs in Denton start at From $600, which covers the inspection, removal of the failed flashing and a new custom-bent detail. The price moves with access, height, the number of penetrations and whether the deck or masonry needs work. A chimney on a steep Victorian roof near the square takes more setup than a skylight on a low-pitch ranch in Southridge. A skylight curb rebuild costs more than a step flashing repair because the curb and seal are part of the job. We quote the repair, not an hourly guess, and we tell you when a repair is not worth it.

Get two or three estimates and compare the scope, not just the number. A low bid that skips the deck inspection or reuses the old flashing will leak again after the next hailstorm. Our full pricing overview explains how we build a flashing estimate and what is included.

Flashing, Chimney & Skylight Repair Near Me: How to Vet a Denton Contractor

When you search for flashing, chimney and skylight repair near me in Denton, you will get a mix of roofers, handymen and storm chasers. The work is detail work, so the contractor matters more than the price. Ask for the license and insurance certificate, ask for local references on metal roofs, and ask who bends the flashing. If the answer is a shelf part and a tube of caulk, keep looking.

• Confirm the contractor is licensed and insured in Texas and ask for the certificate before work starts.
• Get two or three written estimates that list the flashing method and materials, not just a total.
• Ask for references from Denton County jobs on the same roof type you have.
• Check whether your HOA or historic district review applies to visible flashing or chimney changes.
• Ask who pulls the permit if the repair changes the roof structure or deck.
