Signs that point to replacement, not repair
Age plus wear
Curling, cracking and bald shingles across most slopes mean the roof is wearing out as a whole.
Repeated leaks
If you have fixed the same area more than once, the problem is usually the roof, not the last repair.
Soft decking
Spongy spots underfoot or sagging lines seen from the street point to wet or weak wood below the shingles.
Wide hail damage
Bruised or broken shingles on many slopes after a large storm can make spot repairs impractical.
Lewisville hail and housing: what they mean for your roof
NOAA's Storm Prediction Center logged 162 hail reports within 10 miles of Lewisville from 2015 through 2024. Of those, 51 were 1.75 inches or larger, and the biggest was 4.25 inches on June 11, 2023. Hail showed up in 8 of those 10 years. A roof here faces more than heat and age.
Half of the homes in Lewisville were built before 1997 (U.S. Census Bureau, American Community Survey 2020-2024). Many of them have already been reroofed once. Others still carry an older roof that has taken several storm seasons. If you own one of the 46 percent of homes that are owner-occupied, the timing of a replacement is your call. If you rent, report damage to the owner in writing with photos.
A replacement is also the moment to correct what the first roof did poorly. Weak attic ventilation, tired pipe boots and thin underlayment are common on houses of that age. A scope that deals with them helps the new roof cope with Texas heat. Our article on how Texas heat affects asphalt shingles explains why airflow matters.
What a replacement includes
Inspection and written estimate
Measurements, photos and a scope that lists materials, decking repair and ventilation.
Material choice
Asphalt shingle, metal, stone-coated steel or tile. Impact-rated shingles tested under UL 2218 Class 4 are worth asking about in a hail area.
Tear-off and decking check
Old layers come off so the crew can see and replace damaged wood.
Underlayment, flashing and vents
These parts decide how well the new roof sheds water. Read why roof underlayment matters.
Install and clean up
Shingles go on, the yard is cleared of nails and debris and the job is reviewed with you.
Before you sign
Compare estimates line by line, not just the total. Our guide on what to include in a roof replacement estimate helps.
Ask what happens if rotten decking is found once the old roof is off.
If the replacement follows a storm, talk to your insurer early. Coverage depends on your policy and your carrier.
Ask about roof financing. Financing is available.

Frequently Asked Questions
How long does a roof replacement take?
Most homes are done in a short window once materials arrive, but weather, roof size, steep slopes and decking repairs can stretch it. Your written estimate should describe the scope so you know what to expect. Our article on how long a replacement takes in Texas covers the usual factors.
Should I choose impact-rated shingles in Lewisville?
With 51 reports of hail 1.75 inches or larger nearby from 2015 through 2024, many owners ask about shingles rated UL 2218 Class 4. They are built to resist impact better than standard shingles. No shingle is hail-proof, and some insurers treat them differently, so ask your carrier how your policy handles them.
Can a new roof go over the old one?
Laying a second layer over the old one is sometimes done, but a tear-off lets the crew inspect and replace damaged decking and fix flashing properly. Covering an old roof hides problems and adds weight. In most cases a full tear-off gives the new roof a better start.
