How long does a roof last in North Texas?
An asphalt shingle roof in North Texas typically lasts about 15 to 25 years, which is shorter than the 25 to 50 years printed on many shingle bundles. Heat and hail are the reasons. Impact-resistant shingles and good attic ventilation push a roof toward the top of that range, and metal roofs commonly last 40 years or more.
The number on the bundle describes the warranty
A shingle sold as a 30-year or lifetime product is describing the manufacturer’s warranty terms, which are prorated and conditional. The realistic service life depends on the climate the roof lives in.
In Collin County that climate is hard on shingles. Summer roof surface temperatures run well past 150 degrees, and hail comes through most springs.
Heat ages a roof from underneath
An attic without enough intake at the soffits and exhaust at the ridge traps hot air under the decking all summer. That heat bakes the shingles from below, drives the oils out of the asphalt and shortens the roof’s life by years.
Balanced ventilation is one of the cheapest ways to protect a roof, and the easiest time to correct it is during a replacement.
What lasts longer here
Class 4 impact-resistant shingles, tested under UL 2218, resist hail better than standard architectural shingles and often qualify for an insurance discount in Texas. Standing seam metal roofs last far longer than shingles but cost more up front.
Whatever the material, a roof in a planned neighborhood will usually need its colors and materials approved by the HOA first.

How old is too old for a shingle roof here?
Past about 15 years, most shingle roofs in North Texas are worth watching closely, and past 20 most are near the end. Hail can shorten that a great deal.
How can I tell how old my roof is?
Check the closing documents or seller disclosure from when you bought the house, look for a reroof permit on file with the city, or ask a roofer to estimate it from the shingle type and wear.
