Solar Panels on a South Houston, TX Roof: Get the Base Right
On an older house, the biggest solar question is not the panels. It is whether the roof and deck under them can carry them for the long haul.

What an older roof has to handle
Mount anchors
Each mount is screwed into the roof structure. Old or softened decking will not hold them well.
Extra load
Panels and racking add weight. An older frame should be checked before it carries them.
Long service life
Panels are meant to stay up for a long time. The roof under them should have just as many years left.
Sealed openings
Every anchor is a hole in the roof. Flashing at each one keeps water out.
South Houston homes and solar
Half of the homes in South Houston were built before 1969 (U.S. Census Bureau, American Community Survey 2020-2024). Houses about 57 years old often have decking that has been patched, softened by past leaks or covered by more than one layer of shingles. Panels mounted on that base can loosen or leak. An inspection before installation shows whether the roof needs work first.
Ownership is part of it too. In South Houston, 55% of homes are owner occupied. Solar ties equipment to the roof for many years, so the owner makes the call. If you rent, the conversation starts with your landlord.
Hail is the third piece. NOAA's Storm Prediction Center logged 32 hail reports within 10 miles of South Houston from 2015 through 2024, all in 2019, 2023 and 2024. A roof that took hits in those years may have cracked shingles that should be fixed before anything goes on top.

Questions to ask any solar installer
Who checks the roof before installation, and what happens if it needs work?
How is each mount sealed and flashed?

How does the layout leave access for roof maintenance?
How should I check the panels after a hailstorm?
Will the frame and decking be checked before the mounts go in, and who decides if they need reinforcing?
GemSco: roof and solar together
GemSco handles both roofing and solar panel installation, so one team plans the roof and the array.

A simple rule of thumb: compare how long the panels are meant to stay up with how many years the roof has left. If the roof will need replacing well before the panels are done, plan the roof work first. Our article on how long roofing materials last in Texas gives you a starting point for that comparison.
Frequently Asked Questions
Is my old house a good fit for solar panels?
It can be, if the roof and structure are in good shape. Age alone does not rule it out, but older decking and frames need a closer look. An inspection tells you whether the roof can carry panels now or needs repair or replacement first, so you do not install on a weak base.
Should I replace my roof at the same time as installing solar?
If the roof has only a few years left, doing both together usually makes sense. Otherwise the panels will have to come off for the roof replacement later, which adds cost. If the roof is fairly new and in good shape, panels can go on as it is.
What happens to panels during a hailstorm?
Panels are built to handle impacts, but large hail can still crack glass or bend frames. After a big storm, look for visible damage from the ground and have the array and the roof checked. Photos help if you decide to contact your insurance company. Coverage depends on your policy.
