Roof Repair for Duncanville's Older Homes
Many Duncanville houses are nearly half a century old. Their roofs tend to fail in the same few places, and most of those failures can be fixed.

Where older roofs let water in
Valleys
Two slopes meet and funnel water into one channel. Worn shingles or old metal there leak in heavy rain.
Chimneys and walls
Step flashing and counter flashing pull loose or rust after decades. Read about roof leaks around chimneys and vents.
Plumbing vents
Rubber boots crack in the sun and let water run down the pipe into the attic.
Roof edge
Missing or rusted drip edge lets water wick under the shingles and into the fascia.
Old decking
Some homes still have original boards or plywood that soften once they get wet.
Duncanville by the numbers
Half of the homes in Duncanville were built before 1978 (U.S. Census Bureau, American Community Survey 2020-2024). That puts the typical house at about 48 years old. Most of those homes have had the shingles replaced at least once, but the layers under them, the flashing and the vents are often older than the roof on top.
Storms keep testing them. NOAA's Storm Prediction Center logged 69 hail reports within 10 miles of Duncanville from 2015 through 2024, and 13 were 1.75 inches or larger. Strong wind often comes with the same storms. Learn whether Texas winds can lift shingles and what that does to the seal.
The combination is what causes trouble. A tired roof does not need a record storm to start leaking. An ordinary spring thunderstorm can be enough to push water past a seal that has been drying out for years.
What you can do before we arrive
Put a bucket under the drip and move furniture and electronics away.
If the ceiling bulges with water, poke a small hole in the center so it drains in one place.
Take photos of the stain, the attic and the roof from the ground.
Do not climb onto a wet roof.
If the leak is large, ask about emergency roof repair to tarp the area.
Note when it leaks. A leak only in driving rain points to flashing; one in every rain points to a hole.
From first call to finished repair
Find the source
We check from the attic and from the roof. Our guide on how to find the source of a roof leak shows why both views matter.
Show you what we found
Photos of the damage and a free written estimate before work begins.
Repair with matching materials
Asphalt shingle, metal, tile, wood shake or flat sections, repaired with materials that fit the existing roof.
Check the surrounding area
We look at nearby shingles and flashing so the next leak is not a few feet away.
When a patch is not the answer
If the shingles crack when lifted, or there are leaks on several slopes, a repair will only hold for a while. At that point we will explain whether roof replacement in Duncanville makes more sense, and financing is available.

Frequently Asked Questions
Why does my roof only leak during some storms?
Wind direction and rain intensity change how water hits the roof. A worn flashing or a lifted shingle may stay dry in a light rain and leak when wind drives water sideways under it. Leaks that come and go are often flashing problems. Tracking which storms cause them helps narrow down the source.
Is it normal to find old wood boards under my shingles?
On homes as old as many in Duncanville, yes. Some roofs were built on wood boards instead of plywood. They can still be sound, but gaps and soft spots matter. If we find damaged decking during a repair, we show you and explain what needs replacing before new shingles go on.
Can you repair just one spot on an old roof?
Yes, if the rest of the roof is still in fair shape. Old shingles can be brittle, so we work carefully around the repair area. If we find that the shingles around the leak are too worn to hold a patch, we tell you before doing the work, with photos.
