You’re not alone if you’ve felt that pit in your stomach when your PG&E bill shows up. Maybe your roof is nearing the end of its lifespan, and you’ve been told it can’t support solar panels. Or perhaps you’ve heard about 2025 solar tax credits, but the details feel overwhelming.
If you’re asking, “Should I replace my roof before going solar?” The answer might be more straightforward than you think: Do both. At the same time. Here’s why.
Why Bundle Roofing and Solar?
Replacing your roof and installing solar together may sound like a lot, but in reality, it simplifies your life and saves you thousands. Here’s how:
- Lower labor costs: One crew. One timeline. No repeat site visits.
- Unified warranty: Avoid the headache of finger-pointing between contractors if something goes wrong.
- 2025 tax credits apply to both: If bundled correctly, your new roof may qualify under certain circumstances—check with your personal CPA to confirm eligibility.
- Future-proof installation: A solar-ready roof avoids the need for removal and reinstallation down the road.
According to recent reports, Bay Area homeowners can expect to pay $12,000–$20,000 for a roof replacement and $15,000–$40,000 for a solar system. Bundling typically saves 10–15% off the combined cost.
Understanding 2025 Solar Tax Credits & California Rebates
Here’s the good news: The federal solar tax credit (ITC) remains at 30% through 2025. That means you could claim 40% off the entire cost of your roof if it’s bundled with solar as part of a solar-ready install.
California doesn’t offer an extra solar tax credit, but you still benefit from:
- Property tax exclusion for the value of your solar system
- Net Billing (NEM 3.0): You’ll receive credits for sending excess energy to PG&E, though at lower rates than before
- SGIP battery rebates if you add backup storage
Important: AB 942 may force homeowners to lose legacy solar rates when selling their home. Bundling before these changes take effect could lock in long-term value.
ROI: How a Bundled Roof + Solar Package Increases Home Value
Think about your roof like the foundation of your energy system. When buyers see a 25-year solar warranty and a new roof installed by a reputable local company, they gain confidence.
A Berkeley Lab study found homes with solar sell for ~4% more. Combine that with a brand-new roof, and you have a listing that stands out in any market.
- Buyers want turnkey energy efficiency
- Lenders value bundled upgrades in appraisals
- Your home may qualify for energy-efficient mortgage programs
Bottom line: You enjoy savings now, and earn back more when it’s time to sell.
Choosing the Right Bundle for Your Home
Not all roofs or solar systems are created equal. Here’s what we assess when building your custom package:
- Roof age & condition: If it’s 12+ years old, replace before going solar.
- Sun exposure: We evaluate shading, slope, and direction.
- Budget: We’ll help you access financing options like PACE or energy-efficient loans.
- Aesthetic preference: Choose from traditional panels or low-profile solar tiles.
Common mistakes to avoid:
- Letting a solar company drill into your old roof without a structural assessment
- Skipping permit reviews under California Title 24
- Not matching warranties between the roof and solar contractors
We handle it all, so you don’t have to juggle multiple vendors or worry about future leaks.

FAQs About Roof Installation
Can I bundle solar if my roof is less than 10 years old?
Yes, as long as it’s in good shape. We’ll inspect and advise. If repairs are needed, we can factor that into your quote.
Will solar installation void my roof warranty?
No. Because we handle both, we guarantee installation methods that maintain full warranty coverage.
How soon will I see energy savings?
Most homeowners see a 60–80% reduction in PG&E usage within 1–2 billing cycles.
What if a panel leaks or fails?
Panels are sealed and installed with flashings. Our installation warranty and the panel manufacturer cover any defect.
Can I finance both your roof and solar under one loan?
Yes. We partner with lenders offering low-interest energy-efficiency loans and PACE financing.
