Roof Leak
Detection & Repair

We find where the water is really getting in, which is often a vent, flashing or a valley (where two roof slopes meet) rather than the spot above the stain, then fix it and check the wood around it. Our crews work out of Haslet for Dallas-Fort Worth and Irondale for the Birmingham area.

Why choose SWAT Roofing for roof leak repair

We find the real source. Water often runs along the rafters before it drips, so we trace it from the attic back to where it's getting in instead of patching the spot above the stain.

Photos of the cause. You see pictures of what's letting the water in, so you know exactly what we're fixing and why.

Water-tested and warrantied. We run water over the repair to make sure it holds, and every repair comes with a written workmanship warranty.

Signs you have a roof leak


01

Water stains on ceilings or walls

Brown rings or bubbling paint are the most common early warning.

02

Damp or musty attic

Moisture, mildew smell, or wet insulation point to a slow leak.

03

Dripping during heavy rain

Active drips mean water has already passed through your roof decking.

04

Damaged flashing

Flashing is the metal that seals around chimneys, walls and vents, and when it cracks or lifts, it's one of the most common places a roof leaks.

05

Worn pipe boots

Pipe boots are the rubber collars around plumbing vents, and they crack in the sun and let water in.

06

Mold or rot on rafters

Long-term leaks show up as dark staining or dark wood in the attic.

Roof Leak Detection & Repair faq

Water often runs along the rafters and decking before it drips, so the stain can be several feet from where it’s getting in. We trace it from the attic and follow it back to the real source on the roof.

We don’t recommend it. Small leaks lead to rotted decking, mold, and insulation damage that cost far more to fix than the original repair.

Yes. We repair asphalt shingle, metal, tile and flat or low-slope roofs.

If the leak was caused by a covered event like a storm, it may be. Leaks from age or wear typically aren’t. We’ll tell you honestly what we find.

Yes. Every repair comes with a written workmanship warranty.

Put a bucket under the drip and move furniture and electronics out of the way. If water is pooling in a bulging spot on the ceiling, poke a small hole in the center so it drains into the bucket instead of bringing the drywall down. Take photos for your records, stay off the roof, and call us. We can tarp the area until it is repaired.

Most leaks start at the flashing around chimneys, vents, skylights and walls, not in the middle of the shingles. Other common causes are missing or cracked shingles after wind or hail, worn rubber boots around plumbing vents, clogged gutters and valleys where water backs up, and nails that have worked loose over time.

A simple fix like replacing a cracked vent boot or a few shingles costs much less than a repair that involves rotted decking or new flashing around a chimney. We find the source first and give you a written price before any work starts, so you know the cost up front.

You can catch the water inside and protect your belongings, but we do not recommend climbing on the roof, especially when it is wet. Sealant smeared over the spot often traps water and moves the leak somewhere else. Finding the real source usually takes someone who knows where water travels on a roof.

If the leak came from sudden damage, like a tree limb or a hailstorm, many policies cover the interior damage too, such as drywall, insulation and flooring. Damage from a leak that was ignored or caused by an old, worn roof is usually not covered. Report it quickly and keep photos and receipts.

Yes. Wet insulation, decking and drywall can start growing mold within a day or two, and in a warm attic it spreads fast. That is one more reason not to wait. When we fix a leak, we check the attic for wet wood and insulation and tell you if anything needs to be dried out or replaced.

Hard, wind-driven rain pushes water sideways under shingles and flashing in ways a light rain does not. Clogged gutters and valleys can also overflow and back water up under the roof edge. These leaks are often around flashing, vents or the roof edge, and we test those spots during the inspection.

If water is coming through a light fixture, near outlets, or the ceiling is sagging, treat it as an emergency: shut off power to that area and call us. A slow drip is not an emergency, but it should be fixed within days, not weeks, before it rots wood and grows mold.
