Salt, wind and corrosion on coastal roofs
Salt spray speeds up corrosion on metal parts such as nails, screws, vent caps, drip edges and flashing. Using materials rated for coastal conditions makes a difference, and so does detailed work at edges, where wind tries to peel the roof up first. On tile roofs, mortar and fasteners are tested by gusts and pounding rain.
Roads such as Federal Highway, Atlantic Boulevard and I-95 pass through, and wind driven rain can reach parts of roofs that sit dry elsewhere. Flat and low-slope roofs near the water often show bare spots where the coating has been scoured by sun and salt. We look at edges, penetrations and metal parts closely on every coastal call.
