How long does a roof last in Texas?
An asphalt shingle roof in North Texas commonly lasts 15 to 20 years, which is often less than the rating on the package. Heat, poor attic ventilation and hail can all shorten the life of a roof.
Shingle ratings and real-world roof life
A shingle rating describes how the product performs under set conditions. It does not tell you exactly how long your roof will last in North Texas.
Many North Texas roofs need to be replaced before they reach their rated life. This is usually caused by the climate rather than a defect.
What shortens the life of a roof
Heat and UV rays break down the asphalt in shingles over time. The protective granules come loose, and the shingles become brittle.
Attic ventilation also plays a role. A poorly ventilated attic gets very hot in the summer and can age the shingles from underneath. Ventilation is easiest to correct when a roof is being replaced.
Hail can take years off a roof in a single storm.
Options for an aging roof
If your roof is around 15 years old and starting to show wear, you may have more than one option. Depending on its condition, it may need a repair, a roof protectant or a replacement.
Our roof protectant can add 10 to 15 years to a qualifying roof at 4 to 8 times less than the price of a new roof. If your roof is past that point, a replacement is the better choice.
