What Happens If Your Roof Leaks After Solar Installation?

A Leaking Roof After Solar Panels Is More Common Than You Think — and Entirely Preventable

A solar system going up on your roof is supposed to be one of the best days for your home. Lower electric bills. Energy independence. A long-term investment that pays for itself. So when water starts coming through your ceiling weeks or months after those panels were installed, it’s not just a financial gut-punch — it’s a betrayal of trust.

Roof leaks after solar installation happen. They happen in Springfield, IL. They happen in Decatur, Jacksonville, and Chatham. They happen across central Illinois because too many solar companies treat the roof as a platform — something to drill into and walk away from — rather than a system they’re responsible for protecting.

What happens next is where the real problem begins. And understanding it before you sign a solar contract could save you thousands of dollars and months of frustration.

Why Solar Installations Cause Roof Leaks

Every Penetration Is a Potential Leak Point

Solar panels don’t float above your roof. They’re anchored to it — through it — via a series of lag bolts and mounting hardware that pass through your shingles and into your roof deck and rafters. Each one of those penetrations, if not properly flashed and sealed, is a direct pathway for water to enter your home.

Done right, roof penetrations for solar are completely watertight. The mounting hardware is flashed with industry-standard components, sealed with appropriate materials, and integrated into your existing roofing system so water is directed away from every entry point.

Done carelessly — or by a crew that knows solar but doesn’t truly understand roofing — those same penetrations become time bombs. You may not see a drop of water for the first six months. Then an Illinois ice storm hits. Then spring thaw. Then the first heavy rain in May. And suddenly there’s a stain on your ceiling and no clear answer about whose fault it is.

Pre-Existing Roof Conditions That Compound the Problem

Central Illinois roofs take a beating. Hail seasons in Sangamon, Logan, Menard, and Christian counties are legitimate. Ice dams form along eaves during freeze-thaw cycles. UV degradation hits shingles hard over hot summers. A roof that’s 15 or 18 years old may look fine from the ground but have underlying vulnerabilities — cracked underlayment, soft decking, deteriorated flashing around chimneys or vents — that a solar installation crew with no roofing expertise will never catch.

When those vulnerabilities exist before installation and solar goes on top anyway, the eventual leak is almost guaranteed. And when it happens, the question of who caused it becomes impossible to answer cleanly — which is exactly the problem.

What Happens When Your Roof Leaks After Solar — and Two Contractors Are Involved

This is the scenario that plays out for Illinois homeowners far more often than the solar industry likes to admit.

You notice a water stain. You call the solar company. They send someone out who looks at the mounting points, declares them sealed and dry, and tells you the leak is a roofing issue — not their problem. You call a roofer. They look at the area around the panels and tell you the leak is coming from the penetrations — a solar installation issue. Back to the solar company. They point at the roofer. The roofer points back.

Meanwhile, you have a leaking roof. Water is damaging your insulation, your drywall, potentially your electrical system. Every week the dispute goes unresolved is another week of accumulating damage. And if neither contractor accepts responsibility, you may be looking at paying out of pocket for repairs while pursuing legal action — if you can even figure out who to pursue.

This is not a hypothetical. It happens to homeowners in Springfield, Bloomington, Champaign, and communities across Illinois every year. It is one of the most foreseeable and avoidable problems in the solar industry — and it exists almost entirely because the industry normalizes separating solar installation from roofing expertise.

The Insurance Angle

Homeowner’s insurance may cover water damage caused by a contractor’s negligence — but proving that negligence when two contractors are blaming each other is complicated and slow. In many cases, insurers will require you to establish which party caused the damage before they’ll pursue subrogation. That process takes time and costs money your insurance policy may not reimburse.

If your roof was already in poor condition and the solar company should have flagged it — but didn’t — that’s a different layer of liability still. The complexity compounds quickly.

The SunSent Difference: One Contractor, One Warranty, Zero Blame Games

SunSent Solar and Roofing was built specifically to eliminate the scenario described above. Not because it’s a nice marketing story — but because the founders understood, from roofing and solar experience, that combining both trades under one company is the only way to give Illinois homeowners genuine protection.

What One Contractor Actually Means for You

When SunSent installs your solar system in Springfield, Chatham, Rochester, or anywhere across central Illinois, there is one name on the contract. One license. One company that assessed your roof, made any necessary repairs, and then installed your panels on a surface they knew was ready.

If anything goes wrong — a leak, a question about flashing, a concern after a storm — you make one call. SunSent owns the entire project. There is no other contractor to blame. There is no dispute to navigate. There is just a company that stands behind its work because it did all the work.

That accountability isn’t just a convenience. It’s protection — real, contractual, warrantied protection for your home and your investment.

The Pre-Installation Roof Assessment

Before a single SunSent crew member picks up a drill, your roof is assessed. SunSent looks at shingle condition, underlayment integrity, flashing around existing penetrations, decking condition, and the age of the system overall. If your home in Taylorville or Lincoln has a roof that’s borderline — one that might hold up another few years without solar but won’t handle the additional penetrations well — SunSent tells you.

If a new roof makes sense before solar, SunSent can handle both. You get a new roof and a solar system installed together, by the same crew, with a single warranty covering both. No scheduling two separate contractors. No gap in accountability between the roofer who finished last month and the solar crew working this week. No questions about who caused what if something happens in year three.

This is simplicity. This is protection. This is what SunSent means when it says it sells peace of mind.

One Warranty That Covers Everything

Most solar companies offer a manufacturer’s warranty on the panels and a separate workmanship warranty on the installation. Your roof — if the solar company even looked at it — is covered by whatever warranty your roofer gave you, assuming you had one and assuming that the roofer is still in business.

SunSent provides a single, unified warranty covering both the roofing system and the solar installation. One document. One company. If there’s ever a question about a leak, a penetration, a damaged shingle, or a panel issue, one warranty covers it and one company answers it.

For Illinois homeowners who’ve watched contractors dodge responsibility before, this is a fundamentally different experience.

Protecting Your Home Before, During, and After Solar Installation

What to Ask Any Solar Company Before You Sign

If you’re getting solar quotes in Springfield, Decatur, Jacksonville, or anywhere across central or southern Illinois, these questions should be non-negotiable before you hand over a deposit:

Ask about roofing credentials. Is the solar company also a licensed roofing contractor? Or will they be drilling into your roof without formal roofing expertise?

Ask who is responsible if a leak develops. Get the answer in writing. A company that hedges on this question is telling you something important.

Ask how roof penetrations are flashed and sealed. A knowledgeable installer will be able to explain the specific hardware and sealing method they use. Vague answers are a red flag.

Ask about pre-installation roof assessment. Does the company evaluate your roof’s condition before installation? Do they communicate concerns in writing? Will they recommend delays if the roof needs work first?

Ask about the warranty scope. What exactly is covered? For how long? What happens if the company is no longer operating when you need to make a claim?

These aren’t aggressive questions. They’re the questions any informed homeowner should ask. A company that does quality work will answer all of them without hesitation.

What to Do If You Already Have a Leak

If you’ve already had solar installed by a different company and you’re now dealing with a leak, here’s a practical path forward:

Document everything. Photograph the leak, the stain, the exterior around the panels, and any visible damage. Date and timestamp everything you can.

Contact the solar company in writing — email if possible — to create a paper trail. Request a written response to your concern.

Have an independent, licensed roofing contractor assess the leak separately. SunSent can help with this for homeowners across central Illinois. An independent assessment establishes the cause before the dispute escalates.

Contact your homeowner’s insurance carrier. They may be able to pursue the responsible party on your behalf once the cause is established.

If the solar company is unresponsive, the Illinois Attorney General’s Consumer Protection Division handles contractor disputes, and the Illinois Department of Financial and Professional Regulation oversees contractor licensing.

Why Illinois Homeowners Choose SunSent Solar and Roofing

SunSent isn’t a national franchise with local subcontractors. It’s a company grounded in central Illinois — familiar with the weather patterns in Sangamon County, the hail history in McLean and Logan counties, the ice concerns that come with every Springfield winter, and the specific needs of Illinois homeowners who want solar done right.

The SunSent approach is built on a simple belief: if you’re going to put something on someone’s roof, you’d better be the kind of company that’s accountable for that roof. That belief drives every assessment, every installation, and every warranty commitment SunSent makes.

Homeowners in Springfield, Chatham, Rochester, Sherman, Decatur, Jacksonville, Lincoln, Taylorville, Litchfield, Carlinville, and communities throughout central and southern Illinois have trusted SunSent because the alternative — hiring a solar-only company and hoping for the best — carries risks they’re not willing to take with their homes.

What SunSent Customers Are Saying

“I had gotten a quote from another solar company first. When I asked them who was responsible if my roof leaked after installation, they gave me a very vague answer about their ‘workmanship guarantee.’ When I asked SunSent the same question, they walked me through exactly how they handle roof penetrations and told me everything was under one warranty. That was the moment I decided.” — Homeowner, Springfield, IL

“SunSent found a soft spot in my decking during the pre-install assessment that I had no idea was there. They repaired it before putting the panels up. Two years later, zero issues. I’m convinced I would have had a nightmare with any other company.” — Homeowner, Chatham, IL

The Bottom Line on Roof Leaks and Solar in Illinois

A roof leak after solar installation is not inevitable. It is a preventable outcome that becomes far less likely — almost impossible — when your solar installer is also your roofer.

The solar industry has a problem with accountability because it has fragmented the installation process. Solar companies drill holes. Roofers fix roofs. And when something goes wrong at the intersection of those two trades, homeowners get caught in the middle.

SunSent Solar and Roofing exists to solve that problem permanently. One contractor. One warranty. One company that does the roofing and the solar — and stands behind both.

If you’re in Springfield or anywhere across central Illinois and you’re considering solar, do it the right way. Choose the company that can honestly say: if anything goes wrong with your roof or your panels, call us — because we own all of it.
