A city that was built in a hurry
On August 2, 1947, residents of a small community southwest of Dallas incorporated a 225-acre city, largely to keep from being annexed by Dallas. The census counted 841 people in Duncanville in 1950. By 1980 the count was 27,781.
Most of that growth came in the 1950s, 1960s and 1970s, as the census figures show. A postwar Army landing field nearby became Duncanville Air Force Station, and from 1959 the Army ran the command post for the area's Nike-Hercules missile sites there.
What that history means for roofing in Duncanville, TX is simple. Many houses here were built during that boom and are now more than half a century old. The shingles may be fifteen years old, but the decking, the attic ventilation and the flashing around chimneys often date to the year the house was built, or to a re-roof that laid new shingles over old ones.

What an older Duncanville roof can hide
None of these is certain on any one house. They are the questions a careful roofer should answer after looking at yours, in person, from the attic as well as the roof.
Layers
On a house that has had several roofs, ask how many layers of shingles are up there now. A quote that leaves old layers in place is a different job from one that strips to the deck.
Decking
Older homes may have board decking or sheets that have softened around leaks. Ask the roofer to price replacement by the sheet in writing and to photograph any sheet it swaps.
Ventilation
Attic vents added piece by piece over decades do not always work together. Ask what the roofer sees for intake and exhaust, and how its plan changes them.
Flashing
Chimneys, walls and old vent pipes are where aging roofs often leak first. Ask whether the price includes new flashing or reuses the old metal.

Duncanville's permit rule, and whose name goes on it
Duncanville's building inspections guidance follows the building code: work that repairs or replaces a building system needs a permit before it starts, and one or more inspections before it counts as finished. Reroof permits are a routine permit type in the city's weekly reports.
The detail many homeowners miss is the city's warning about who applies. If you pull a permit for work a contractor does, Duncanville says you become responsible for that work. The city recommends that the contractor apply in its own name.
- Contractors must register with the city before working in Duncanville, through the Citizen Access Portal.
- Permit applications go through the same portal, or on paper at City Hall, 203 E. Wheatland Road.
- A permit is valid for six months from the day it is issued.
- The city lists the 2021 International Residential Code among its adopted codes.
- Questions: Permit and Inspection Services, (972) 780-5000, open Monday through Friday during business hours.

Hail and wind on Duncanville roofs
Duncanville sits in the same spring storm belt as the rest of Dallas County, and hail and straight-line wind are what most often send people looking for a roofer here. No weather service damage survey of a tornado inside Duncanville turned up in the research for this page, so none is claimed here. If a storm has just passed, here is what to do, all from the ground:
- Inside first. Look at ceilings, especially near outside walls and under any chimney. Set out a bucket and move belongings away from a drip.
- Photos from the yard. Missing shingles, dents in gutters and vents, and limbs on the roof. Take dated pictures.
- Call your insurer. Ask how your policy handles wind and hail, what your deductible is, and how long you have to report damage.
- Then a roofer. Have the roofer document what it sees in photos, and ask about a temporary cover if the roof is open.
Leave the roof to the roofer. A wet or storm-hit roof is slippery, and damaged decking can give way, so keep off it and keep the ladder put away. Stay clear of any downed power line and report it to Oncor or your local electric utility, or call 911. Inside, pull furniture and electronics away from the drip, set out a bucket or towels, and keep everyone out of a room where the ceiling is sagging. Take photos from the yard and from inside, then call your insurance company and a roofer.
Your deductible is yours to pay. The Texas Department of Insurance warns that a contractor may not waive your deductible, rebate it, or pad the estimate to cover it, and that a contract of $1,000 or more paid with insurance money must include a notice that you owe the deductible. Your insurer may ask for proof you paid it. A contractor also may not act as a public adjuster on a property it works on or may work on. If a roofer offers to "take care of" the deductible, hire someone else.
Five questions for a Duncanville roofer
- Is your company on Duncanville's contractor register, and will the reroof permit carry your company name rather than mine?
- How many shingle layers are on my house now, and does your price remove all of them?
- After looking in my attic, would you change the vents, and how?
- Is decking priced per sheet in the contract, with photos of each replaced sheet?
- Will your insurance company send me a certificate of your liability coverage directly?
No state license for roofers. Texas does not license roofing contractors. A 2025 bill that would have had the state license re-roofers (HB 3344) cleared a House committee but never got a floor vote, and it died when the session ended. That puts the checking on you: ask for a certificate of liability insurance sent to you by the roofer's insurance agent or insurer, a written contract that lists the full scope, the permit or contractor registration your city requires, addresses of nearby jobs, and proof the shingle warranty was registered. The line does none of this checking for you. How to check a roofer in Texas.
