It’s a very common question we get from people when they are thinking about installing solar panels; will installing solar panels void my roof warranty?
The short answer is NO!
Installing solar panels on most roofs will not void the manufacturer warranty. Most roofing manufacturers these days want to be “solar friendly” and have written instructions on how to install PV solar panels on their roofing systems.
Some roofing manufacturers have even produced their own hardware to mount solar panels on their roofing systems!
Solar panel installations have exploded across the USA and roofing manufacturers are working to cooperate with solar installations.
What Roofing Manufacturers Say About Solar
Some roofing manufacturers are more friendly to solar than others. Roofing manufacturers like GAF and CertainTeed have started producing their own solar shingles and roofing systems.
Certain shingle manufacturers like Owens Corning and GAF have technical bulletins stating that installing solar panels on their shingles will NOT void the warranty. It is very helpful when manufacturers are this direct and have documentation to backup what they are saying.
Other manufacturers like Atlas and IKO also have documentation showing that installing PV solar will NOT void their warranties.
The only shingle manufacturer that does not have any documentation online about installing solar is Tamko. I called a local rep for Tamko and discussed it with him. He said installing solar panels on a Tamko shingle will NOT void the warranty.
Solar panels can also be installed on tile, metal, stone coated steel, and some synthetics/composites.
