Why Solar and Roofing Are Intertwined
Solar panel installation and roofing are more connected than most homeowners realize until something goes wrong. Standard rack-mounted solar panel systems require lag bolts that penetrate through the roofing material — through the shingles, through the underlayment, and into the roof deck and rafters below. Each penetration point is a potential leak point and creates localized stress on the surrounding shingles and the flashing system around it.
Most roofing contractors' workmanship warranties specifically exclude coverage for areas disturbed by subsequent tradespeople. The language is typically something like: "This warranty does not cover damage caused by others working on or around the roof after installation." Solar installers are "others." If a solar installer creates a leak at a penetration point, your roofing contractor's workmanship warranty likely does not cover the repair.
Manufacturer warranties — the 30 or 50-year shingle warranties that seem so impressive — often contain similar language about third-party modifications and unauthorized penetrations. Read your specific warranty carefully, because voiding a manufacturer warranty through solar installation is a real and documented outcome that has left homeowners with no recourse when shingles fail prematurely.
The Re-Roof Before Solar Decision
The practical rule that SMI applies to every customer asking about solar: if your roof is within 10 years of its expected end of life, replace it before solar installation. The math is straightforward.
A solar array that is installed on a 15-year-old roof will need to come off when that roof is replaced. Removing, storing, and reinstalling a residential solar array typically costs $2,500 to $5,500 depending on system size and local electrical labor rates — and that cost requires a licensed electrician for disconnect and reconnect in addition to the removal crew. That expense comes entirely out of pocket, on top of the roof replacement cost itself.
If your roof has 15 or more years of remaining life based on an honest professional inspection, proceed with solar and the economics still work well. The breakeven math for a typical Arkansas solar installation runs 7 to 12 years, so a roof with 15+ years remaining gives you a reasonable payoff window before the issue arises.
If your roof is 18 to 20 years old and showing signs of age, replacing it now — before your solar quote is signed — is almost always the smarter sequence. An SMI inspection will give you an honest remaining lifespan estimate, not a sales pitch for replacement. That assessment is free and takes about 20 minutes.
Protecting Your Warranty When Getting Solar
If your roof has adequate remaining life and you are proceeding with solar, these steps protect your warranty and minimize leak risk:
- Get a documented pre-solar inspection. Have SMI inspect and photograph the roof condition before solar installation begins. This creates a baseline record that protects you if a dispute arises later about what was pre-existing versus solar-installation damage.
- Choose a solar installer who uses proper flashed penetration systems. Quickmount PV, IronRidge FlashKit, and similar products flash each penetration point correctly rather than simply running a lag bolt through the shingle and applying sealant. Properly flashed penetrations have dramatically lower leak rates over time. Ask your solar installer specifically which penetration system they use — "we use sealant" is the wrong answer.
- Get the solar installer to warrant their penetration work in writing. A reputable solar company will provide a separate warranty for their roof penetration work — typically 10 years. Get it in the contract before signing.
- Understand your roofing contractor's warranty terms on third-party penetrations. Ask SMI specifically how our workmanship warranty handles areas where solar is later installed. We can explain exactly what is and is not covered under different scenarios.
What to Do If You Need Both a New Roof and Solar
If your inspection reveals you need a new roof and you also want solar, you have two clean paths forward:
Option A: Re-roof first with SMI, then install solar. This is the cleanest sequence. You get a full workmanship warranty on the new roof, manufacturer warranty intact, then the solar installer works on a fresh roof surface with no questions about pre-existing condition. Warranties from both contractors are clear. This is the approach we recommend in most cases.
Option B: Coordinate both projects simultaneously. SMI can work alongside your solar installer — we install the new roof and the solar crew follows with their racking and penetration work the same week. This minimizes the window between roof completion and solar installation, and we can directly supervise the quality of penetration flashing at the time of installation. This approach requires coordination but is viable with the right solar partner.
Either way, it starts with an honest conversation about your roof's current condition. Schedule your free inspection and we will give you the information you need to sequence your projects intelligently.
