How long should a roof last in the Dallas Fort Worth area?
A roof in North Texas often does not last as long as the manufacturer’s rating, because summer heat and hail are hard on shingles. The age and type of shingle, the direction the roof faces and your attic ventilation all affect how long your roof lasts.
The manufacturer rating
A shingle’s rating is useful for comparing products, but it does not predict exactly how long a roof will last on a particular home.
Sun exposure makes a difference. A slope that faces south in full sun will usually wear faster than a shaded slope on the same house.
Heat and hail
Texas summers are hard on roofs. Heat and daily temperature swings wear shingles out over time.
Hail can shorten the life of a roof much faster. Many roofs in North Texas are replaced because of storm damage before they wear out.
Attic ventilation
In the summer, an attic without proper ventilation can reach temperatures over 160 degrees. That heat can age your shingles early and make your air conditioner work harder.
Proper ventilation balances air intake at the eaves or soffits with exhaust at or near the ridge. The Federal Housing Administration recommends at least one square foot of attic ventilation for every 300 square feet of attic space.
Frequently Asked Questions
Are impact-resistant shingles worth it in North Texas?
For many homeowners, yes. Class 4 impact-resistant shingles hold up better to hail, and some insurance companies offer premium discounts for them. Ask your agent about the discount.
Does a lighter color roof last longer?
Lighter and energy-efficient shingles reflect more heat, which can help. Ventilation and installation also make a big difference.
How can I find out how old my roof is?
Permit records and the seller’s disclosure from when you bought the home often show it. A roof inspection can also give you an estimate.
