Taking Solar Panels Off and Back On in Galveston
When the roof under a solar array needs work, the panels have to come off. On the coast, the reasons and the details are a little different.

Why Galveston panels come down
Wind damage to shingles or flashing around and under the array.
A leak at a mount, often where flashing has rusted or a seal has failed.
A full roof replacement on an aging roof.
Soft decking found near attachment points.
Roof work needed to meet windstorm requirements for insurance.
Panels shifted or racking loosened by strong wind.
Plans to sell the home, when buyers want a sound roof under the array.
What the local numbers tell you
Half of the homes in Galveston were built before 1973 (U.S. Census Bureau, American Community Survey 2020-2024). Some panels went onto roofs that were already partway through their life, and those roofs will need replacing while the panels still have years left. Salt air also shortens the life of metal flashing and fasteners at the mounts.
Hail is rarely the trigger here. NOAA's Storm Prediction Center logged only 2 hail reports within 10 miles of Galveston from 2015 through 2024, with a maximum of 1.75 inches on April 25, 2015. Wind is the more likely cause of damage under an array. And with only 46 percent of homes owner occupied, the decision often falls to a landlord.
Left alone, small leaks under an array spread quietly across decking that nobody can see. Read why roof damage may not cause an immediate leak to understand the delay, and why a check after each major storm pays off.
How removal and reinstallation work
Photos first
Each panel, the racking and the roof are documented before work.
Careful removal
Panels and rails come off in order.
Plan where panels go
Agree before the job where the panels will sit, away from wind and foot traffic.
Roof work
Repair or replacement, with new flashing at each mount point.
Reinstall
Rails and panels go back on, every penetration sealed.
Coastal details to settle in writing
Mount hardware
Ask whether rusted fasteners and flashing will be replaced, not reused.
Windstorm paperwork
All of Galveston County is in the TWIA catastrophe area. Ask your agent what the roof work needs, such as a WPI-8.
Insurance
If a storm caused the damage, ask your insurer how panel removal is treated. Coverage depends on your policy. See roof insurance claims.
Timing
Plan to avoid having the roof open in the peak of storm season.
Before the crew arrives
A little preparation keeps the job smooth. Clear the driveway and the area under the roof edge where panels will be lowered. Move cars and outdoor furniture, and keep pets and children away from the work zone. Let tenants know the schedule if the home is a rental.
Keep your system paperwork handy, including any records of how it was first installed. After the work, ask for photos of the new flashing at each mount before the panels went back on, and file them with your roof records.

Frequently Asked Questions
How do I know if the roof under my panels is damaged?
Signs include stains on the ceiling under the array, shingle pieces or flashing in the yard after a storm and rust streaks below mounts. From the attic, look for damp spots near attachment points. An inspection with photos confirms whether panels need to come off.
Should I replace the roof while the panels are off?
If the roof is near the end of its life, yes in most cases. Removing panels twice costs more than doing it once. On a younger roof with limited damage, repairing the affected area and putting the panels back may be all you need.
Will reused mounts leak on a new roof?
They can if old flashing and worn seals are put back. On the coast, rusted hardware is a common leak source. Ask for new flashing at every mount point and get the plan in writing before work begins.
