Solar panels themselves do not automatically void shingle warranties, but the installation process can sometimes affect the warranty coverage. Most shingle manufacturers’ warranties include clauses that limit coverage if the shingles are altered or damaged during installation. This means if a roofer drills or attaches mounts improperly, causing leaks or other damage, the warranty may not cover those issues. It’s important to check your shingle manufacturer’s specific warranty terms before installing solar panels, as requirements can vary. Some manufacturers even offer “solar-ready” shingles or have specific guidelines to follow to maintain the warranty. A simple way to do a basic check is to inspect your roof before and after solar installation for any visible damage, such as lifted granules or punctures around the mounts.
To protect both your roof and warranty, it’s wise to ask your solar installer and roofer whether they are familiar with your specific shingle warranty and if they will follow any special installation protocols recommended by the manufacturer. You might ask, “Can you provide documentation on how the installation will comply with my shingle warranty terms?” and “Have you worked with this brand of shingles before, and do you guarantee no damage during the solar panel mounting?” If the job requires roof penetration, a qualified roofer should be involved to ensure proper flashing and sealing. Calling a roofer before solar installation or for a post-installation inspection is a safe way to catch potential warranty issues early and maintain the integrity of your roof and its coverage.
