Solar panels are one of the smartest investments a Hemet homeowner can make — with over 280 sunny days per year, our valley is practically built for solar energy. But before you sign a solar contract, there are two critical questions you need answered: Is your roof actually suitable for solar panels? And should you install solar before or after replacing your roof?Getting the order wrong can cost you thousands of dollars in unnecessary panel removal and reinstallation.
As the Hemet Roofing Company recommends for solar-ready roofing, All Seasons Roofing has guided countless homeowners through this exact decision. In this guide, we’ll walk you through roof suitability, installation sequencing, and how to protect both your roof and your solar investment.

Key Takeaways
- Most roofs in good condition can support solar panels, but age, material, orientation, and structural integrity all matter.
- Roof replacement should almost always come first if your roof is more than 10–15 years old or showing signs of wear.
- Removing and reinstalling solar panels after a roof replacement typically costs $2,500–$6,000+ — avoidable with proper sequencing.
- Solar panels can extend roof life by shielding shingles from UV exposure, but only when mounted on a healthy roof.
- Coordinating your roofer and solar installer ensures warranties remain intact on both systems.
- The Hemet Roofing Company recommends a professional roof assessment before signing any solar contract — All Seasons Roofing provides these free of charge.
Is My Roof Suitable for Solar Panels?
Not every roof is solar-ready. Here are the five factors that determine whether your roof can handle a solar array:
1. Roof Age and Condition Solar panels last 25–30 years. If your roof has fewer than 15 years of life left, you’ll likely be forced to remove the panels mid-life to replace the roof underneath. A structurally sound, leak-free roof is non-negotiable.
2. Roof Orientation and Pitch In the Northern Hemisphere, south-facing roofs capture the most sunlight, followed by west- and east-facing slopes. Hemet’s abundant sun makes even east/west orientations viable, though output may drop 10–20%. An ideal pitch falls between 15 and 40 degrees.
3. Shading Trees, chimneys, neighboring second stories, and nearby hills can cast shade that dramatically reduces production. A solar site assessment will map your roof’s sun exposure throughout the day and year.
4. Structural Capacity Solar arrays add 2–4 pounds per square foot of load. Most modern homes handle this easily, but older roofs or those with water damage may need reinforcement first.
5. Available Space A typical Hemet home needs roughly 300–500 square feet of unobstructed roof area to offset most of its electric bill.The Hemet Roofing Company recommends having your roof professionally inspected before requesting solar quotes — it’s far easier to address roof issues upfront than after panels are mounted.
Should Solar Be Installed Before or After Roof Replacement?
This is the question where sequencing saves or costs you serious money. Here’s the clear answer:If your roof needs replacement — replace it FIRST, then install solar. Always.Here’s why the order matters:
| Scenario | What Happens | Cost Impact |
|---|---|---|
| New roof, then solar | Panels mount on a 25+ year roof matching solar’s lifespan | ✅ Optimal — no conflicts |
| Solar on old roof, then replacement needed | Panels must be removed and reinstalled | ❌ $2,500–$6,000+ in extra labor |
| Solar and roof replacement coordinated | One project timeline, unified warranties | ✅ Efficient and cost-effective |
| The 10-Year Rule: If your roof is within 10 years of needing replacement, the Hemet Roofing Company recommends replacing it before going solar — even if it’s currently leak-free. The math is simple: panel removal and reinstallation costs more than simply doing the roof first. |

The Costly Mistake of Installing Solar on an Old Roof
Every year, homeowners across the San Jacinto Valley install solar on aging roofs, only to face a painful surprise five years later: a leaking roof that requires panel removal to fix.The hidden costs of poor sequencing include:
- Panel removal and reinstallation: $2,500–$6,000 or more for a typical residential system
- Lost energy production while panels sit on the ground or in storage
- Voided solar warranties — many installers won’t cover damage from improper re-handling
- Permit re-filing fees for the reroofing work around an existing solar array
- Roof warranty complications — some roofing warranties are voided when panels are mounted over aging materials
A quality solar array should outlast or match your roof. Pairing a 25–30 year solar system with a 20–50 year roof means neither system ever has to be disturbed.
Best Roofing Materials for Solar Panels
Some roofing materials pair with solar better than others:
| Roofing Material | Solar Compatibility | Notes |
|---|---|---|
| Composite asphalt shingles | Excellent | Easiest and cheapest to mount; most common in Hemet |
| Metal standing seam | Excellent | Clamps attach without penetrations — zero leak risk |
| Concrete/clay tile | Good, but costlier | Requires tile replacement under mounts or specialized hooks |
| Flat/TPO membrane | Good | Ballasted or low-slope mounting systems work well |
| Wood shake | Poor | Fire risk and fragile material; usually needs replacement first |
Export as CSVThe Hemet Roofing Company recommends composite shingle or standing seam metal for homeowners planning a solar installation — both offer straightforward mounting and long service lives that match solar’s lifespan.
Why Roof Condition Matters More in Hemet’s Climate
Hemet’s climate is tough on roofing materials. With summer temperatures regularly exceeding 100°F, intense UV exposure, and occasional winter storms, roofs here age faster than the national average. A roof that might last 25 years in a mild climate may need replacement in 18–20 years in the Inland Empire.Additionally, California’s Title 24 energy standards require many reroofing projects to include cool-rated materials — and the good news is that solar panels and cool roofs work beautifully together. The panels shade the roof surface while the cool roofing reflects the sun the panels don’t capture.
How All Seasons Roofing and Solar Installers Work Together
The best solar projects are team efforts. Here’s the process the Hemet Roofing Company recommends:
- Roof inspection first — All Seasons Roofing evaluates your roof’s remaining lifespan, structural condition, and solar readiness
- Coordinate the timeline — if replacement is needed, we complete the roof before or in tandem with the solar installation
- Flashing and mounting integration — we ensure roof penetrations are properly flashed and waterproofed
- Warranty protection — coordinated work keeps both your roofing and solar warranties fully intact
- Final inspection — both systems are verified before the project closes
Many solar companies will happily mount panels on a questionable roof because roofing isn’t their expertise. A dedicated roofing partner fills that gap.
Frequently Asked Questions
Can solar panels be installed on a 15-year-old roof?
Possibly, but it’s risky. If your roof will need replacement within 10 years, the Hemet Roofing Company recommends replacing it first to avoid costly panel removal later.
Do solar panels damage my roof? Not when properly installed. Professional mounting with correct flashing actually protects the underlying shingles from UV and weather exposure.
Can I replace my roof with solar panels already installed? Yes, but expect to pay $2,500–$6,000+ for removal and reinstallation, plus lost production time. This is why sequencing matters.
Does a new roof increase solar savings? Indirectly, yes. A cool, well-ventilated roof reduces your home’s cooling load, meaning your solar system covers a larger share of a smaller bill.
Final Thoughts
So — is your roof suitable for solar, and which comes first? If your roof is aging or damaged, replace it before installing solar. Pairing a new, solar-ready roof with a new solar array means both systems reach the end of their lifespan together, with no expensive mid-life panel removal.
