Planning a Roof Replacement in Schertz
When a roof reaches the end of its life, the best replacement is a planned one. Here is how to read the signs and what the job involves.

Five signs your roof is done
Shingles that crack, curl or snap when lifted.
Bald patches where the granules have washed away.
Leaks in more than one room, or that come back after repairs.
A sagging ridge or wavy lines across the slopes.
Water stains or soft boards on the attic decking.
Why so many Schertz roofs are due
Half of the homes in Schertz were built before 2002 (U.S. Census Bureau, American Community Survey 2020-2024). A roof installed when one of those homes was new is now about 24 years old. At that age, many original asphalt shingle roofs are showing wear, especially on the slopes that get the most sun.
About 78 percent of occupied homes here are owner-occupied (U.S. Census Bureau, ACS 2020-2024), so most households will face this decision directly. The upside is time: with large hail rarer here, many owners can plan a replacement before the roof forces the issue.
Hail risk is lower here, not zero
The record
NOAA's Storm Prediction Center logged 30 hail reports within 10 miles of Schertz from 2015 through 2024.
Large hail
Only 1 report was 1.75 inches or larger: 2 inches, on April 12, 2016.
What it means
Fewer big storms than many nearby areas, but one storm is enough to damage an old roof.
When replacing
Shingles tested to UL 2218 Class 4 are built to resist impact and are worth comparing.

Tear-off and install
Old layers come off, damaged decking is replaced, and the new system goes on.
Final cleanup
The yard and driveway are cleared of nails and debris.
What changes under the shingles
A replacement is more than new shingles. On a roof around 24 years old, the underlayment has dried out, the pipe boots have cracked and the flashing may have been resealed more than once. A full tear-off replaces all of it at the same time, which is why leaks that kept coming back usually stop.
Ventilation is part of the job too. Hot attics bake shingles from below, and many older homes have too little intake or exhaust. Fixing that during replacement helps the new roof age more slowly. Read how roof ventilation protects your home and why roof underlayment matters for the details.
Budget and timing
Financing is available, and you can learn more on our roof financing page or in roof financing options. GemSco offers discounts for military, first responders and seniors.
Choosing a season matters too. Read the best time of year to replace a roof in Texas. If you are not ready yet, roof repair in Schertz can keep the current roof working while you plan. See our roof replacement service for more.
Frequently Asked Questions
How long do roofs last in Schertz?
It depends on the material, ventilation and the storms the roof has seen. Standard asphalt shingles in the Texas heat often wear out sooner than metal or tile. With half of Schertz homes built before 2002, many original roofs are reaching the point where replacement should be on the calendar.
Should I replace before I sell my home?
It depends on the roof's condition and the market. A roof near the end of its life can come up in a buyer's inspection and affect the offer. A roofer's inspection before listing tells you whether a repair is enough or replacement makes more sense.
Do I need to replace the gutters too?
Not always. If they are in good shape, they can usually stay or be reinstalled. Replacing a roof is still a good time to look at them, because the drip edge and fascia are exposed and any rot can be fixed in the same job.
