During the installation of a solar panel system, numerous property owners express concern regarding potential damage to their roofs. Given that these installations typically endure for approximately 30 to 35 years, it’s crucial to guarantee that installing panels doesn’t compromise the integrity of your roof. Fortunately, instances of roof damage resulting from a solar panel installation are exceedingly rare, as installers implement precautionary measures to prevent leaks and other forms of damage.
Installing solar panels properly typically does not damage your roof. Like any home improvement project, choosing the right service provider is crucial for a successful rooftop solar job. For most homeowners, installing solar panels will not result in roof damage as long as your solar installer is a licensed, qualified professional and your roof is in good condition. Instances of roof damage occurring because of a solar installation are likely due to the roof’s initial poor condition.
The first step is to ensure you’re working with a reputable installation company. You can connect with high-quality solar installers on SolarWiki. We thoroughly vet all our installer partners to ensure only the best companies provide quotes through our platform. If you have concerns about roof damage, you can inquire with your chosen installer about their installation process and the measures they take to prevent roof damage. You can also invite installers for site visits to inspect the roof and address your questions in person. Additionally, it’s wise to inquire about their workmanship warranty and whether it covers any potential damage to your roof. You also need to thoroughly review the solar proposal you get.
The Process of Installing Solar Panels on Your Roof
Concerns about roof damage during a solar panel installation are understandable. Installing racking and solar panels alters a core part of your home’s structure, posing risks if done incorrectly.
One significant concern is the holes drilled in your roof to secure the solar panels’ racking. These holes accommodate lag bolts, securing the panels to the roof, and are designed to withstand extreme weather. Though necessary for almost every solar installation, the size and depth of these holes vary based on your roof’s material.
However, installers implement safety measures to maintain your roof’s structural integrity and prevent leaks. Flashing surrounds the bolt fixture to prevent water penetration, sealed with tar or similar material. Additionally, the hole around the lag bolt is filled with a sealant to further protect against water seepage.
Concerns about the added weight of solar panels are also common but typically unfounded. Roofs are designed to withstand much more weight than solar panels add, and installations on angled roofs allow snow to slide off in snowy climates.
Alternative Solar Installation Options
If you’re concerned about roof penetrations, there are alternative solar options. Solar roof tiles or shingles integrate photovoltaics into roof shingles, eliminating the need for traditional panel mounting. However, these options are still costly, and the technology isn’t as efficient as traditional panels.
For flat roofs, ballast mounting systems or ground mounts offer alternatives to avoid roof penetrations. Additionally, joining a community solar plan allows you to receive solar energy from an offsite location, eliminating the need for rooftop panels.
