New Solar Panels & your New Roof
Should you get a new roof before solar panels?
In most cases, yes. Getting a new roof before solar panels is the smart move whenever your current roof is more than 10 years old or shows leaks, curling shingles, or general age. Solar panel systems are designed to last 25 to 30 years, and once they are bolted down, the roof underneath has to last just as long. If your shingles wear out in five or eight years, you will have to pay to remove the panels, replace the roof, and reinstall the system.
In Central Texas this matters even more. Intense summer heat, spring hail, and straight-line winds age Austin roofs faster than the national average, so a roof that looks fine today may not have 25 years left in it. A reputable Austin roofing company can tell you exactly how much life your roof has left before you commit to solar.
How much does it cost to remove and reinstall solar panels for a roof replacement?
Taking panels off and putting them back on for a future roof replacement typically adds $1,500 to $6,000 to the job, depending on system size and complexity. That cost is on top of the roof itself, and it buys you nothing but the inconvenience of scheduling two separate crews. Re-roofing first, or doing both projects together, avoids that expense entirely.
| Approach | Relative cost | Best for |
|---|---|---|
| New roof first, then solar | Lowest long-term cost | Roofs over 10 years old or worn |
| Roof and solar together | Shared labor and scaffolding savings | Aging roofs and new builds |
| Solar now, re-roof later | Adds $1,500 to $6,000 to remove and reinstall | Only newer roofs with 20-plus years left |
Coordinating the two trades up front also avoids gaps in coverage where a leak could form between projects.
What should you check on your roof before installing solar panels?
Before any panels go up, your roofer should confirm the roof is ready to carry them for decades. Key things to assess include:
- Roof structure: The deck and framing must be sound, with no soft spots, active leaks, or storm damage. A roof inspection catches issues before they are hidden under an array.
- Roof age and lifespan: Match the remaining roof life to the 25 to 30 year solar lifespan. If the gap is large, re-roof first.
- Orientation and slope: South-facing sections with full Texas sun and a suitable pitch produce the most power. A solar expert can confirm the layout.
- Roofing material: Asphalt shingles, metal, and concrete tile all give panels a secure, sturdy base to mount to.
- Tax incentives: Federal, state, and local solar incentives change often, so research current programs and deadlines before you buy.
How do roof warranties and solar panels work together?
This is where homeowners get caught off guard. Drilling mounts into a roof can void parts of a manufacturer or workmanship warranty if the work is not done correctly. Before installation, confirm two things in writing: that your new roof warranty stays valid with panels installed, or that the solar company covers any roof issues their mounting creates.
- Ask whether penetrations are covered and who is responsible if a leak appears around a mount.
- Review both the solar warranty and the roofing warranty for repair, refund, and deadline terms.
- Have your roofer and solar installer coordinate so neither blames the other later.
As a GAF Master Elite contractor certified since 2005, Driftwood Builders Roofing installs solar-ready roofs in a way that keeps your coverage intact and gives the solar crew a clean, code-compliant surface.
Why coordinate your roofer and solar installer in Austin?
The smoothest projects happen when the roofing and solar teams talk to each other from day one. Coordinating means the panel layout respects the roof’s strong points, mounts land on solid framing, and there is no finger-pointing if something needs attention later. Doing both jobs in one window also shares scaffolding and labor costs and shortens the time your home is a worksite.
For Austin and Central Texas homeowners in cities like Cedar Park, Round Rock, Leander, Georgetown, and Lakeway, local roofing and code realities matter too. Heat, hail, and wind loads all shape how a roof should be built to host solar for the long haul.

Frequently Asked Questions
Do I really need a new roof before installing solar panels?
Not always, but you should if your roof is more than 10 years old or shows wear. Because solar panels last 25 to 30 years and are hard to remove, the roof beneath them should have a matching lifespan to avoid costly future removal and reinstallation.
How much does it cost to remove solar panels to replace a roof?
Removing and reinstalling a residential solar system for a roof replacement typically adds $1,500 to $6,000, depending on system size. Re-roofing before you install solar avoids this expense completely.
What roofing materials work best with solar panels?
Asphalt shingles, metal, and concrete tile all provide a secure, durable base for mounting solar panels. The right choice depends on your home, budget, and how long you want the roof to last under the array.
Will installing solar panels void my roof warranty?
It can if the mounting work is done incorrectly. Confirm in writing that your roof warranty remains valid with panels installed, or that the solar company covers any roof issues caused by their installation.
