Proper nailing is essential to good performance. To ensure proper nailing during shingle application it is required that you follow the IBC and IRC nail
Read more →Introduction Photovoltaic (PV) systems convert sunlight into electricity. These systems have been successfully installed on residential asphalt shingle roofs for many years. The two common attachment methods are rack-mounted and roofintegrated: The latter method is sometimes referred to as building integrated photovoltaics. Framed rigid PV panels/modules are commonly mounted on
