Most modern roofs can support solar panels, which typically add only 2-4 pounds per square foot. Key factors include roof age, material type (tile vs. shingle), structural condition, and proper weight. . Dead loads represent the permanent, static weight of the solar installation itself. This includes every component that adds to the roof's burden. When calculating the necessary load capacity of a roof, you need to figure in what's known as the dead load along with live loads or environmental loads. Typical dimensions are about 65 inches by 39 inches, resulting in roughly 17.
