Trip: Not if they are installed correctly.

The racking system joins the solar panels to your roof. A hole must be created in the rafter to secure the racking system. To prevent water from getting through the new hole, the bolt will be surrounded by flashing, which is a metal or plastic shield that fits under existing roof tiles. This flashing is additionally sealed with tar or comparable material. The lag bolt hole is also filled with a sealant to protect against water drainage in your roof.

Solar panels actually serve as a barrier to protect your roof from sun, rain, snow, and hail. The panels are made to withstand exposure to various weather conditions.

In addition to providing a barrier from harmful weather, rooftop solar arrays allow air flow between the roof and the solar panels, which increases airflow and adds a cooling effect of the solar array. In turn, the cooling helps the efficiency of solar panels.

Rooftop solar can turn your roof from a liability to an asset. Your rooftop goes unused without solar. Rooftop solar can produce your own energy with the option to net meter unused energy.
