Installing solar panels on your roof can be great for your wallet, the planet, and maybe even your property value. But here’s the part most people gloss over: your roof. If your roof isn’t up to the task, you could be setting yourself up for leaks, damage, or costly repairs down the road.
Before those shiny panels go up, here are three ways that you should prepare your roof and protect it during installation.
Consider Your Roof’s Age and Condition
Depending on the age of your roof, the things that you’ll want to do to prepare and protect it during solar panel installation will vary.
Most asphalt shingle roofs last around 20 to 25 years. If yours is pushing that limit, you might want to replace the shingles and other parts of the roof before installing panels. Otherwise, you’ll end up paying twice: once for the panels, and again to take them down and reinstall them when it’s time to reroof.
Not sure about your roof’s condition? A certified roofing inspector can give you a solid assessment and help you to know if your roof is ready for solar panel installation.
Prepare For The Mounting System
Solar panels need a sturdy, well-mounted base. That means these mounts will have to be drilled into your roof. Done right, this won’t spell disaster. But if this process is done wrong, you could end up with water leaks, wood rot, or even mold.
To avoid this, make sure your installer uses flashing and sealants to create a watertight barrier around every bolt. And if you’ve got a flat or tile roof, there are specialized mounting systems that avoid unnecessary damage.
Work With Licensed, Insured Pros
Installing solar panels on the roof of your home isn’t a DIY weekend project. Roofing and solar work are both specialized trades. You need an installer who’s licensed, insured, and ideally certified by NABCEP, which is the gold standard in the solar industry. Ask for proof, not promises.
Also, double-check that their warranty covers both the solar system and your roof. Some companies will partner with roofing contractors for extra protection, which is a smart move if something goes wrong later.
Once the panels are up, they actually can help protect your roof by shielding it from direct sun and rain. But you still need to keep an eye out. Clear off debris, trim overhanging branches, and have everything inspected every few years to make sure things are still looking how they should.
Prepping your roof is the foundation of a good solar setup. A little planning now means a safer roof, a smoother install, and way fewer headaches down the line. So if you’re considering getting solar panels installed on your roof soon, consider using the tips mentioned above to help you prepare for this and learn how to best protect your roof during the process.
