Flashing, Chimney & Skylight Repair in Houston

Houston sits on flat Gulf Coast prairie about 50 feet above sea level, crossed by bayous and built on expansive clay that shifts with every wet and dry cycle. That clay moves foundations, and that movement opens seams around chimneys, skylights and brick transitions. When tropical rain arrives sideways in a June squall or a September hurricane feeder band, Flashing, Chimney & Skylight Repair in Houston is the work that stops the water before it reaches your ceiling. We bend metal on site for a precise fit around every penetration, matching the profile and gauge to your existing roof. If you have already seen a ceiling stain, start with our metal roof leak repair service and we will trace the source back to the flashing.

Why Flashing Fails First on Houston Roofs

Of all the leak points on a Houston roof, flashing fails first and most often. The reason is local: our rain does not fall straight down. Thunderheads build over the prairie on summer afternoons and dump two inches in an hour, driven nearly horizontal by 40 mph gusts. That water climbs under lifted step flashing, through cracked sealant at a chimney cricket, and around skylight curbs that were caulked instead of properly flashed. Add live oak and pine debris holding moisture against the metal, plus UV that bakes sealant brittle in two or three summers, and the penetration is the first place to give.

• Chimney step flashing pulls loose as the clay soil shifts the foundation and the chimney mass moves against the roof deck.
• Skylight curbs installed with caulk and no back pan leak within a few seasons of Houston heat cycling.
• Valley flashing on low-pitched Heights and Montrose bungalows traps pine needles and backs water up under the panels.
• Brick-to-roof transitions on 1940s and 1960s ranches in Oak Forest and Spring Branch rely on old tar and mortar that cracks and separates.
• Sidewall and headwall flashing on two-story stucco homes in Clear Lake and Pearland takes wind-driven rain straight into the joint.

Every one of these is a water entry point you can fix before it rots decking or stains a ceiling, and catching them early is far cheaper than a deck replacement.

Key info: A homeowner in Meyerland called us after a May hailstorm because water was running down the inside of the chimney breast. The step flashing had been nailed through the face instead of woven into the courses, and the sealant was gone. We rebuilt the cricket and re-flashed the chimney in one day, and the stain never spread past the drywall tape.

For the code side of roofing work in the city, the City of Houston building department is the authority to check with before any structural change around a chimney or skylight.

How We Repair Flashing, Chimneys and Skylights in Houston

We work from the leak backward, not from a sales pitch forward. First we get on the roof and find where the water actually enters, because a stain on a Kingwood ceiling is often ten feet from the penetration. Then we open the joint, remove the failed flashing and sealant, inspect the deck and framing for rot, and fabricate new metal to fit the opening. Nothing gets caulked over and called done.

1. We inspect the roof and attic to trace the water path and photograph every failed joint.
2. We remove the old flashing, sealant and any rotted decking around the penetration.
3. We bend new flashing in house to match the profile, gauge and color of your roof.
4. We install step flashing woven into the courses, plus a proper cricket behind chimneys wider than 30 inches.
5. We set skylight curbs on a back pan and seal the perimeter with compatible sealant, not silicone over old caulk.
6. We water test the repair and show you the photos before we leave the property.

If the inspection turns up storm damage beyond the flashing, we hand it to our storm and wind damage repair crew so the whole repair is documented in one file.

Key info: On a 1920s raised-pier bungalow in the Heights, the chimney sat on its own footing that had settled differently from the house. We fabricated a slip-joint flashing that allows the two structures to move independently, so the next clay cycle will not tear the joint open again.

Repair Approaches We Use on Houston Metal Roofs

The right approach depends on the roof profile, the penetration and how much movement the structure sees. Here is how we match the method to the job.

We choose the method after we see the deck, not before, because a caulk-and-go repair on a moving chimney will fail again by the next rainy season.

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

Most flashing and penetration repairs in Houston start at From $600 and climb from there based on how much has to be opened up. That starting figure covers a straightforward re-flash of a single penetration with new metal and sealant, plus the water test. The price moves when the job turns into a rebuild.

• Chimney width and height drive cost, because a wide chimney needs a cricket and more formed metal.
• Rotted decking or framing under the penetration adds carpentry time and material.
• Roof pitch and access matter, and a steep two-story roof in Sugar Land takes more setup than a single-story ranch.
• Number of penetrations matters, since a roof with three skylights and a chimney is a bigger scope than one leak.
• Matching existing panel profile and color on a standing seam or stone-coated steel roof can require custom bending.

Get two or three written estimates and compare scope line by line, not just the bottom number, because a cheap bid that skips the cricket will cost you again next storm. Our full pricing overview lays out how we build an estimate.
