Asphalt Shingle Roofs
The solar industry came up with solutions for installing solar panels on nearly all roof materials including asphalt shingle roofs on residential homes. Typical asphalt shingles that cover many of the homes in America, or sturdy commercial-grade metal roofs, there’s likely a tried and true way to securely install the panels.
Solar panels have been mounted to hundreds of thousands of homes across the United States using a lag bolt and flashing. The bolt is attached to the rafters of the roof, tightly securing the solar panels and the racking system.
To ensure there is no possibility of leaking, a piece of flashing is placed underneath the shingle.
