To measure a roof, start by safely accessing it with a ladder and measuring tape. Note the length and width of each rectangular section, then multiply for area. For triangular sections, measure the base and height, then take half of that product. Add all sections together for total square footage, multiplying by a pitch factor if the roof is steep to account for slope. Always work with a partner and use proper fall protection.
