Roofs of commercial buildings require periodic inspection to ensure that they "serve to protect the building" as required by the International Building Code. Inspections could take into account the buildup of water on the roof, which could compromise steel roof decks and insulation, and other parts such as flashing and skylights to prevent water damage during storms with strong winds. Roofing contractors should be hired for a thorough inspection that complies with safety standards.
