How are the solar modules attached to the roof, and what effect do they have on the roof shingles?

The aluminum support structure which is underneath the modules are attached directly into the roof rafters of the home.

They are guaranteed to withstand 90-125 mile per hour winds and the weight of the modules is evenly distributed. The modules place a distributed load of less than 3 pounds per square foot on the roof, which is well within roof loading requirements of local building codes. The modules will actually protect the roof shingles under them from the sun, which is the force which cause roof shingles to dry up and curl. In addition, the solar modules block hot summer sun from hitting the shingles, which leads to cooler attic temperatures and decreased cooling costs.

An asphalt-based sealant is placed between the shingle and aluminum support structure to prevent leaks from occurring.
