Solar panels don’t damage your roof when installed properly
Solar panels are not inherently bad for your roof. The potential for solar panels to damage your roof stems from the method of installation. Just like any home improvement project, using the right service provider is essential to a 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. If you hear of roof damage occurring because of a solar installation, it’s likely because the roof was initially in poor condition.
Traditional solar panel installation involves the bolting of panels to your roof with nails, bolts, and straps. These nails and bolts are typically driven directly through the roofing and into the attic or ceiling. Unsurprisingly, holes in the roof can lead to leaks forming over time. With the presence of unexpected moisture, the possibility of water damage and mold growth becomes very real. On that note, damage to shingles and roof tiles from drilling or hammering during solar panel installation is almost guaranteed.
If you are concerned about damage to your roof, you can question your installer of choice about their installation process and measures they take to prevent roof damage using their online messaging center or invite installers out for site visits so they can inspect the roof and answer your questions in person. It’s also worth asking any company about their workmanship warranty, and whether or not it covers your roof on the off chance damage occurs.
Solar Panels & Roof Protection
Other than the obvious purpose of harnessing the sun’s energy to create renewable electricity, solar panels also serve to protect your roof. Solar panels form a protective barrier between your roof and the outside elements. Having solar panels on your roof can help protect it from mother nature’s wrath. Outdoor elements such as wind, rain, snow, and the occasional falling tree are prevented from directly hitting your roof and causing damage.
Solar panels also absorb direct sunlight that would otherwise fall directly on your roof. The gap between the panels and your roof forms an air pocket that also has a cooling effect on your roof. One study shows that installing solar panels can decrease a home’s internal temperature by up to 5 degrees Fahrenheit. According to a team of researchers led by Jan Kleissl, a professor of environmental engineering at the UC San Diego Jacobs School of Engineering.
Given this information, solar panels can actually protect your roof from a number of potential damages. Additionally, homes located in an area known for harsh weather conditions will weather any storm thrown their way.
No Worries About Voided Warranties
It’s best to have solar panels installed on a roof that is no more than five years old. Some installers will not even consider doing a solar panel installation on a roof that has been on for many years. Eventually, the roof is going to need replaced. Solar companies work hard to make sure your panels are set correctly. They take a considerable amount of time to ensure the work is handled professionally in a way that will not cause a roof warranty to be voided. With US Solar ensuring safe, damage free installation is a top priority for customers.
