Solar power is becoming more popular, and for good reason: it costs less, is cleaner, and comes with long-lasting warranties. But homeowners everywhere are asking the same thing: “Can solar panels damage your roof?”

After working in roofing for twenty years, we can say with confidence that solar panels don’t harm roofs by themselves, as long as they are put up appropriately. Old roofs, bad installation, or not keeping up with maintenance are what really cause problems.

These aren’t just odd problems anymore; around 5 million households in the U.S. already have solar systems, and Nevada alone has over 110,000 installations. So, let’s talk about what truly happens when solar panels are put on your roof, the risks you should be aware of, and how to make sure your installation protects your home instead of hurting it.

The Starting Point: A Healthy Roof Matters

Before talking about panels, any installer should evaluate your roof. Solar panels last 25 to 30 years. If you need to replace your roof in 5 years, putting up panels first could entail more effort and greater prices. Your installation should quickly go through this list:

Roof age and remaining life
Any existing leaks or rot
Structural capacity for added weight
Roof material and slope

The most common reason people blame solar panels for roof damage later is that the roof wasn’t ready. The best approach to keep problems from happening in the future is to fix the roof first.

How Solar Panels Can Cause Problems (And How to Prevent Them)

There are a few real issues with solar panels on roofs, but most are preventable:

Improper penetrations — mounts bolted through the roof must be flashed and sealed. Poor sealing = leaks.
Prevention: hire professional installers who know how to apply the right flashing, EPDM/rubber boots, and sealants. Request to see pictures of their work.
Bad load calculation — an overloaded roof can sag or fail over time.
Prevention: structural assessment. Most modern homes can accommodate residential solar, but older roofs may need extra support.
Installer mistakes during removal/reinstall — if panels are removed for roof work, careless crews can break tiles or disturb shingles.
Prevention: Planning roof work with your solar business ahead of time can make sure that professionals securely take down and put back up the panels.
Debris and critters under panels — leaves, nests, and dirt can trap moisture, leading to rot in extreme cases.
Prevention: install critter guards and schedule periodic inspections/cleaning.

If you follow those criteria, the chances of solar panels damaging your roof will go down a lot.

Do Solar Panels Ruin Your Roof or Can They Help It?

Panels generally protect the roof surfaces they cover, even if it seems counterintuitive. They keep direct sunlight and hail from hitting the roof, which slows down UV damage. That being said, the areas around the mounts and under the panels need to be looked at because that’s where leaks start if the mounts are put in wrong.

So, to answer the question “Do solar panels damage roofs?” the answer is no, although bad installation or an old roof can cause problems.

Are Broken Solar Panels Dangerous?

Two main concerns:

Electrical risk: cracked glass or damaged wiring can produce arcing or shorts if not isolated.
Glass/debris hazard: shards or loose fragments can fall.

Call your installer right away if you spot any damage. Microinverters or optimizers that separate panels are common in modern systems. This lowers the risk. Still, don’t touch shattered panels, and keep kids and pets away until a professional comes.

Warranties, Insurance, and Resale

Will putting solar panels on my roof void my warranty? Maybe. Some roofing companies want proof or approved ways to install their products. Always:

Ask the roofer and the solar company to coordinate.
Get roof-penetration or installation warranties in writing.
Keep records and photos of seals and flashing.

Most homeowners’ insurance policies cover storm damage even if you have panels installed, but you should let your insurance company know before you install them. If you want to sell, it’s usually easier to sell your panels if you own them instead of renting them.

How to Protect Your Roof When Going Solar

Before Installation:

Get a Professional Roof Assessment: Don’t get one from the solar company; instead, get an independent roofing contractor, like Rhino Roofing, to check the state of your roof and how long it will last. This usually costs between $200 and $500, but it can save you tens of thousands of dollars in the long run.

Time It Right: If your roof is more than 15 years old and you’re thinking about getting solar panels, you should really think about getting a new roof first.

Choose Your Installer Carefully: Look for companies that:

Employ licensed, insured installers
Offer workmanship warranties (not just equipment warranties)
Have specific experience with Las Vegas roofs
Can provide local references you can actually visit

During Installation:

Verify Proper Methods: Make sure installers are:

Using high-quality mounting systems designed for your roof type
Installing proper flashing around all penetrations
Following manufacturer specifications exactly
Creating watertight seals with appropriate sealants

Get Documentation: Ask for pictures of the installation process, including close-ups of the flashing and sealing work. This keeps you safe if problems come up later.

After Installation:

Schedule Regular Inspections: Have a professional check your roof every year, not only the solar provider. We suggest that you get your home inspected in Las Vegas before summer and again after the rainy season.

Address Issues Immediately: That little leak you don’t care about? It will cost $5,000 to fix instead of $500 in six months. Don’t wait.

Maintain Both Systems: Keep panels clean (dusty panels produce less power) and gutters clear. Debris buildup can trap moisture and cause problems.
