How long should a roof last in the Dallas Fort Worth area?
An asphalt shingle roof in North Texas commonly lasts somewhere between twelve and twenty years, even when the shingles are rated for twenty-five or thirty. Heat and hail both shorten the life of a roof, and good attic ventilation helps it last longer.
What a shingle rating means
A shingle rating describes how the product performs under test conditions. It is useful for comparing shingles, but it does not predict exactly how long a roof will last on a particular home.
Sun exposure, shade, roof pitch and ventilation all affect how quickly a roof ages, even on the same house.
How heat and hail affect a roof
In a Texas summer, a roof gets much hotter than the air during the day and cools at night. Over the years, that heating and cooling wears out the shingles and weakens the seal between them.
Hail can shorten the life of a roof in a single storm. In North Texas, many roofs are replaced after hail damage before they have worn out from age.
Why attic ventilation matters
A poorly ventilated attic traps heat under the roof deck, which ages the shingles faster. Balanced ventilation, with intake vents at the eaves and exhaust vents near the ridge, helps the roof last longer.
Ventilation problems are common, such as blocked soffit vents or too few intake vents. A roof replacement is a good time to correct them.

Are impact-resistant shingles worth it?
They can be, because they hold up better to hail, and some insurance companies offer a discount for them. Ask your insurance agent how much the discount would be.
Does a lighter-colored roof last longer?
A lighter roof stays somewhat cooler, which can help. Ventilation and installation quality make a bigger difference.
How do I find out how old my roof is?
Check local permit records or the seller’s disclosure from when you bought the home. A roof inspection can also give you an estimate.
