Storm-Ready Vinyl Roof Soffits

Bob looks at storm-ready features on the Punta Gorda house, starting with the front door that is outswinging with a stop to prevent blow-in. He also points out the impact-resistant glass that is being used throughout the house. Leslie Chapman-Henderson talks with Bob about soffit details that are being incorporated in the storm-ready house. The problem with poor soffits is that during a storm wind-driven rain and wind force their way up under the roof, into the attic where wind force attacks the structure and rain soaks the insulation and walls. In humid climates wet insulation and wallboard begin to grow mold within hours. Closing the soffit to penetration is not currently a code requirement but is critical to smart building in storm zones. Joe Breese from Alcoa shows Bob the vinyl soffit that is being used in the Punta Gorda house. The locking panel system means that wind will force the panels to grip tighter to one another rather than pull apart. The panels are connected to a j-channel that is attached to the wall. They are installed with 5/8-inch stub nails spaced every 16 inches. The soffit panels are cut to fit and stapled in place. There are no ventilation grilles evident on these vinyl panels. All air moves through the grooves in the panels to ventilate the roof and attic space. Still, these panels have about 80 percent more ventilation capacity than standard vinyl soffit panels.
