Property exposure at the roofing contractor’s own location is generally limited to those of an office, shop, and storage of materials, equipment, and vehicles. Solvents, chemicals, or sealants used in roofing operations may be flammable, requiring proper storage and separation from combustibles. If repair work on owned vehicles and equipment is done in the building, fire hazards may be high due to the presence of oils, fuels, and other combustibles. When hot built-up roofing is done, any preparation work with hot tar and asphalt heated at the yard site increases the fire potential for both the insured and to neighbouring properties. Equipment, materials, and supplies stored in the yard have higher exposures to wind, vandalism, and theft.
