Solar Panels and Your Roof: What Texas Homeowners Should Know First
The roof under the panels matters more than the panels. Get the order right.
By the Apex Roofing team · Central Texas
Solar is everywhere in Central Texas right now. Between the strong sun, rising summer electric bills, and federal incentives, homeowners from Georgetown to Killeen are putting panels on their roofs at a fast clip. What too many of them skip is the most important question of all: what condition is the roof under those panels? Panels last twenty-five years or more. If you bolt them onto a roof with eight years of life left, you are setting up an expensive problem down the road. The roof has to come first.
Why roof age is the deciding factor
Solar panels are designed to outlive most asphalt shingle roofs. If your roof is near the end of its service life, installing panels on it means that when the roof fails, a crew has to remove every panel, replace the roof, and reinstall the panels. That removal and reinstallation can run thousands of dollars on top of the roof itself. The smart move is to look honestly at the roof age before any panels are ordered. A roof with most of its life ahead is a good candidate. A worn roof should be replaced first.
The right sequence
- Get an honest roof inspection. Find out the real remaining life of the roof before talking to a solar company.
- Replace the roof if it is aging. If the roof has under ten years left, replacing it before solar is almost always cheaper than removing and reinstalling panels later.
- Choose a roof material that suits panels. Architectural asphalt and standing seam metal both take solar mounts well.
- Coordinate the two crews. A roofer and a solar installer who communicate keep the warranty intact and the penetrations sealed correctly.
How panels affect your roof
Solar mounts attach to the roof with brackets that penetrate the shingles and fasten into the rafters. Done right, each penetration is flashed and sealed so it never leaks. Done wrong, every bracket is a future leak point. This is exactly why roof condition and quality flashing matter so much before panels go up. Interestingly, panels can also protect the roof area beneath them by shading it from direct UV, which is a small bonus in our intense Texas sun.
Metal roofs and solar
Standing seam metal pairs especially well with solar because the panels can be clamped to the seams without drilling any holes through the roof surface. For a homeowner planning solar who is already considering a new roof, a metal roof can simplify the install and remove a whole category of leak risk. Our guide on metal vs shingle roofing covers the trade-offs in detail.
What to ask before you commit
- How much service life does my current roof realistically have?
- Will the solar installer guarantee the roof penetrations against leaks, and for how long?
- Does adding panels affect my existing roof warranty?
- Who is responsible if a leak appears around a mount later, the roofer or the solar company?
Warranty coordination between two companies
One detail that trips up homeowners is how the roof warranty and the solar warranty interact. When a solar company drills mounts into a roof, it can affect the roofing manufacturer warranty or the contractor workmanship warranty if the penetrations are not done to spec. The cleanest approach is to have your roofer and solar installer talk before the panels go up, agree on how the mounts will be flashed, and put in writing who is responsible if a leak appears around a mount later. If the roof is new, ask whether the solar install will void any part of the roofing warranty. Sorting this out before installation avoids the finger-pointing that happens when a leak shows up and each company blames the other. A little coordination up front protects you on both sides.
