Before installing a satellite dish, skylight, or even scheduling a roof cleaning, make sure the work won’t turn your roofing warranty into a worthless document.

Homeowners sometimes forget about the fine print. While every roof warranty is different, a few common mistakes could void yours completely. Any upgrade to your exterior should start with a call to your original roofing company.

Highly rated roofers on Angie’s List share some of the more common issues that can void a warranty, and some roof warranty tips to prevent it.

Antennas and Satellite Dishes

Mounting an antenna or satellite dish may seem harmless, but the damage it can cause isn’t, especially if not done by a professional. Drilling into your roof can create openings for leaks, which might void the warranty coverage.

James Braddy, co-owner of Over the Top Roofers in Orlando, warns: “If you install an antenna or satellite dish, you could void at least part of the warranty.”  Even a seemingly simple home upgrade should start with a call to your original roofing company or, if they’re no longer available, another reputable roofing company in your area. To avoid costly mistakes, keep these roof warranty tips in mind before making changes.

Skylights and Solar Panels

Major roof modifications like skylights or solar panels can void your warranty if done improperly or without the roofer’s knowledge. Dave Hancock, president of Raneri & Long Roofing and Windows in El Cajon, puts it simply: “From both the manufacturer’s and contractor’s perspective, you can’t expect a new roof full of holes to perform well.”

That doesn’t mean you can’t install these features. It just means you need to do it right. Your roofer can coordinate with your solar or skylight installer, remove and reinstall shingles as needed, and ensure your warranty stays intact.

“It’s a matter of coordination,” Hancock says. “If you want something done to your roof after the fact, you should involve the original roofing contractor.” Remember, if the contractor installing your skylight or solar panels offers a separate warranty, don’t assume you’re fully covered. Always double-check with your roofer. 

Pressure Washing

Trying to blast away moss or grime with a pressure washer might seem like a good idea on the surface, but it’s one of the fastest ways to destroy both your shingles and your warranty.

For example, Hancock once worked with a commercial client who pressure-washed his roof to get rid of grease buildup. The result was less than ideal. “Whoever did it put huge gouges in the roof. They literally destroyed the membrane,” he says.

Instead, use soft-wash roof cleaning methods or consult a roofing professional before cleaning. Avoid anyone recommending high-pressure tactics.

Poor Ventilation

Improper attic ventilation isn’t just bad for your energy bills. It can also cause early roof failure. “Improper attic ventilation can also nullify your roofing warranty,” says Mike Carter, general manager of highly rated Fentress Builders in Indianapolis. “Inadequate venting can trap heat in your attic and wear out your shingles,” he continues.

Protect Your Warranty Before You Lose It

Many homeowners don’t think about their warranty until it’s too late. But a little planning can go a long way. Whether you’re adding solar panels, installing a skylight, or simply cleaning your roof, always check in with your roofer first—and get everything documented.

If your original roofer is no longer available, search for “roofing companies near me” with solid reviews and clear communication. The best contractors will help you navigate your warranty terms and avoid costly missteps.

Protecting your roof starts with knowing the rules. And the best time to ask is before you make a change.
