Adapted from an article written by Julie Zeidnerfor Coastlines, a maga- zine published by the New York Sea Grant Institute. Homeowners Should Screw Down Roofing Material to Thwart Hurricane Damage Hurricanes that rage through coastal communities often wreak the most havoc for homeowners by ripping apart their roofs. Many folks respond by pounding in more nails, but a South Carolina Sea Grant researcher has found that a screwdriver, not a hammer, is the best defense against high winds. Timothy Reinhold, professor of civil engineering, and other researchers at Clemson University used their wind- research facility to compare the effectiveness of screws and nails when holding down roof sheathing. Roofing material secured properly with screws withstood up to five times more wind pressure than material held in place by nails only. The American Society of Civil Engineers established guidelines after Hurricane Andrew devastated Florida. They required that roof sheathing be held in place with nails every three inches on edges and at corners. How- ever, nails driven this close to each ! other could cause rafters to split and thus weaken the roof's ability to withstand high winds. Reinhold recommends that homeowners use No. 8 screws to attach the plywood underlayer to the rafters when they reroof and that they space the screws 12 inches apart. According to Reinhold, homeowners will spend less than $300 on the modifications for a 2,000- square-foot roof.
