Mounting solar panels on a metal roof.

The type of metal roof will affect the type of solar mounting system needed for a successful install. There are many products on the market that will allow you to mount solar panels. Use the right self drilling screws. Standing seam metal roofs have rails the seams built right in ready for direct attachment of solar panels this integrated and cost free feature makes solar mounting quick and convenient.

Roll insulation under many metal roofs is already crushed at the cross beams and further fastening is an not issue. Each mounting manufacturer has a different design and way to attach to sinusoidal corrugated roofs. Use types that are made for self drilling through a metal roof into wood. See image to the left.

I have solar panel on my corrugated metal roof and not sure if the solar panel roof mounting is to blame as the rubber on top of the bolt is not covering the whole bolt head however there is a rubber between the corrugated sheet and bracket. The shingles must be removed to attach the mounting hardware to the roof then the layers of shingles and flashing are installed with holes to allow the attachment point to stick out. In fact metal roofs are the best type of roof to pair with solar panels.
