Once the area of the roof ’s footprint is known the overall roof area can be found by accounting for the pitch of the roof. In the United States, a run of inches (foot) is use and pitch is measured as the rise of the roof over inches. Enter the diameter of the roof ridge vent gap (1-3) Finally, enter the coverage area (width) of the panels you plan to buy. For instance a panel will have an effective coverage width of 36.
