Taking Solar Panels Off and Putting Them Back for Roof Work in Houston
When the roof under an array needs work, the panels must come off. The job has to protect the panels, fix the roof properly and leave every mount sealed.

Why Houston owners need panels removed
The roof wore out
The shingles under the array reached the end of their life before the panels did.
Hail hit the roof
Shingles around and under the array were damaged and cannot be fixed with panels in place.
Leaks at mounts
Old attachments were not flashed well and water is getting in.
Debris and pests
Leaves and nests under the array trap moisture against the roof.
Panel or racking problems
Cracked panels or loose racking need to be dealt with on the ground.
The local picture
Half of the homes in Houston were built before 1982 (U.S. Census Bureau, American Community Survey 2020-2024). Many solar arrays in the city were installed on roofs that were already aging. As those roofs reach the end of their life, the panels have to come off before the new roof can go on.
Storms add to the list. NOAA's Storm Prediction Center logged 40 hail reports within 10 miles of central Houston from 2015 through 2024, and 9 were 1.75 inches or larger. Hail fell in 2016, 2019, 2023 and 2024. A roof damaged in one of those storms cannot be properly repaired around an array. Our guide on how to identify hail damage on asphalt shingles shows what to look for on the exposed parts of the roof.
The process, step by step
Record the layout
The array is photographed and mapped: panel positions, wiring routes and mount points.
Settle the shutdown
Confirm with your solar provider who shuts the system down before any panel is handled.
Remove and label
Panels and racking come off and are labeled so they go back in the same layout.
Plan where panels go
Agree in writing where the panels will sit during the roof work and who is responsible for them.
Do the roof work
Repairs or a full replacement are done with the whole deck exposed.
Re-flash the mounts
Each attachment point gets new flashing and sealant on the new roof.
Reinstall
Racking and panels go back on, and the site is cleaned up.
Planning tips
Get a roof inspection first to decide between a repair and a full replacement.
If the roof is old, replace it while the panels are off rather than paying for removal twice.
Ask for a written estimate that lists removal, roof work and reinstallation as separate items.
Plan for the days the system is not producing power.
If hail caused the damage, ask your insurer how removal and reinstallation are handled. Coverage depends on your policy and your insurer.
For rentals, the owner decides and should be part of the plan from the start.
Choosing the roof that goes under the panels
Since the panels will sit on the new roof for years, pick a material with a long life. Impact-rated shingles tested to UL 2218 Class 4 resist hail better than standard ones, and metal and stone-coated steel are other common options. Our guide on how long roofing materials last in Texas compares them.

Frequently Asked Questions
Can the roof be repaired around the panels instead?
Small repairs at the edge of an array sometimes can be. Anything under the panels, or a full replacement, requires taking them off. Working around an array risks damaging the panels and usually leads to a repair that does not last.
Will my panels be damaged by removal?
Panels are made to be handled during installation and can be removed safely with care. Risk comes from rough handling or poor storage. Ask how panels will be labeled, stored and protected, and have them checked for cracks before they go back on the roof.
Are new mounts needed when the panels go back up?
The racking can often be reused if it is in good shape, but each attachment should get new flashing and sealant on the new roof. Pieces pried up during removal are often distorted and leave gaps under the shingles.
How do I know if my roof needs work before the panels come off?
Leaks below the array, granules in the gutters, hail damage on the exposed roof and rusty or loose mounts are all signs. A roof inspection in Houston checks the visible roof and the attic below the array to tell you what is needed.
