Solar on a Pflugerville Roof: Get the Roof Ready First
Panels sit on your roof for a long time. In Pflugerville, roof age and four years of large hail are good reasons to check what is under them before they go up.

The right order for a solar project
Decide on the roof
Repair what is needed, or replace if the roof is close to the end of its life.
Plan the array
Layout that respects valleys, vents and drainage paths.
Mount and flash
Each attachment sealed with proper flashing, not just sealant.
Install and check
Panels set, then a final look at the roof surface around the array.
Roof questions that affect solar
Remaining life
The roof should outlast the panels, or you pay to remove them later.
Structure
Decking and framing must hold the mounts and the added weight.
Material
Shingle, metal and tile each need different hardware.
Ownership
Only the owner can approve a roof and solar project.
What Pflugerville's data says about roofs under solar
Half of the homes in Pflugerville were built before 2004 (U.S. Census Bureau, American Community Survey 2020-2024). Many of those still have their original roof, about 22 years old. That is often close to the end for standard shingles in Texas heat, so it is the first thing to check before panels go on.
Storms are the second. NOAA's Storm Prediction Center logged 86 hail reports within 10 miles of Pflugerville from 2015 through 2024, and 32 of them were 1.75 inches or larger. Large hail fell nearby in 2021, 2022, 2023 and 2024. A roof that went through those years without an inspection may have hidden cracks. Once panels cover it, finding and fixing those cracks means taking the panels off.
About 70 percent of homes in Pflugerville are owner occupied. Owners can plan the roof and the solar together, which is the cheapest way to avoid doing the work twice.
Questions to ask any solar installer
Will you inspect the roof before designing the system?
How will each mount be flashed and sealed?
Will panels block any vents or drainage paths?
Who do I call if a leak shows up near the array later?
What happens to the roof under the panels if it needs repair?
Will the layout leave room to reach vents and roof sections for future repairs?
Why work with a roofer for solar
Every mount is a penetration in your roof. A roofer knows how to flash it so it does not leak, and can tell you honestly whether the roof will last as long as the panels. GemSco handles both roofing and solar panel installation. Read our post on how to protect your roof before severe weather, and learn more on our solar panel installation page.
If the inspection shows the roof needs replacing, doing it first is usually the cleaner path. New underlayment, flashing and shingles go down, then the mounts are placed and flashed into a fresh roof. That way the roof and the panels start their lives together. If panels are already on your roof and it needs work, see solar panel removal and reinstallation in Pflugerville for how that is handled.
Frequently Asked Questions
Should I replace my roof before going solar?
If your roof is near the end of its life or has hail damage, usually yes. Panels stay on for a long time, and removing them later to replace the roof adds cost and hassle. An inspection first tells you whether the roof has enough life left to carry the panels.
Can solar panels cause roof leaks?
The panels themselves do not, but the mounts can if they are not flashed properly. Each attachment goes through the roof. Proper flashing directs water around it, while a dab of sealant tends to fail with heat. Ask how every mount will be sealed before work starts.
What happens to the roof under the panels during hail?
The panels cover part of the roof, but the edges and nearby slopes are still exposed, and damage near the array is harder to see. After a large storm, have both the panels and the roof checked, including the area around and under the array.
