Many areas in the country are prone to hail and hurricanes. To protect roofing systems from both, it’s a good idea to look for wind- and impact-rated roofs. Wind ratings should conform to ASTM International standards. Impact ratings should conform to UL 2218. Ask your roofing specialists for these types of materials when undertaking a roofing project. Here are our recommendations.
Wind clips or storm anchors are better in high-wind or seismic areas. Two screws per tile give the highest wind uplift resistance, which keeps them from shifting. Installation is critical for hip and ridge tiles in high-wind areas. A high-quality, water resistant-underlayment is a must.
Clips or cleats instead of exposed fasteners are perfect for metal. They aren’t exposed to weather and allow the metal to expand and contract. This reduces the opportunity for buckling. If using exposed fasteners, your storm damage repair experts recommend that they should be corrosion-resistant and be able to penetrate the sheathing.
Wood Shingles and Shakes
For a roof replacement, your contractor should not install new shingles over old ones. The contractor must inspect the sheathing and make any repairs necessary. The first course of shingles should be sealed to the starter strip with roof cement. If your building is within 3,000 feet of saltwater, the nails or screws should be stainless steel.
Slate should be always attached with flat head copper-wire slating nails. In high-wind areas, roof cement or polyurethane sealant should secure the slate. Four nails per slate are necessary. We recommend high-quality, durable underlayment for installation or any roof repair.
