A roof replacement is an opportunity to enhance roof deck attachment, roof framing connections, roofing underlayment, and flashing as needed to meet new standards and building codes. Homes located in coastal high-wind areas including hurricane-prone regions (defined in the IRC as areas along the Atlantic and Gulf Coasts where wind velocity is >115 mph, and Hawaii, Puerto Rico, Guam, the Virgin Islands, and American Samoa) generally require products and attachments that can withstand greater wind speeds than the rest of the country (see the wind map from the IRC in the Climate tab). Metal roofing is also fire resistant.īuilding codes require roofing to be rated for the local wind zone. Impact-resistant roofing is also available to help protect against damage by windborne debris and hail. Metal roofing that is selected and installed for high-wind applications is much less likely to be damaged or blown off the roof during a storm. Figure 1. The clips holding these metal roofing panels were set too far from the roof eave (above the red line) and the panels lifted in strong winds (Source: FEMA 2009). Unsealed joints or penetrations in the roof sheathing or storm damage can allow rainwater to enter the building causing severe damage, including saturation of insulation and ceiling drywall, potentially leading to collapsed ceilings and extensive damage to interior finishes and household contents. Exposed sheathing will eventually succumb to water damage. See the Compliance Tab for related codes and standards requirements, and criteria to meet national programs such as DOE’s Zero Energy Ready Home program, ENERGY STAR Certified Homes, and Indoor airPLUS.ĭuring a hurricane, tornado, high winds, or hailstorms, metal roofing can be damaged or blown off the roof, exposing the underlayment, flashing, and sheathing as the only protection against rainwater.

Install flashing at roof penetrations and wall-intersections, properly integrated with roofing and wall underpayments and coverings.Install metal roofing in accordance with manufacturer’s installation instructions, all applicable building codes, and selected best practices.Install metal roof panels and other roofing products that provide uplift resistance equal to or greater than the design uplift pressure for the roof based on the site design wind speed and exposure category, as required by the IBHS Fortified Home Hurricane and High Wind Standards.install a two-layer #30 felt underlayment system (recommended best practice).install a nominal 4-inch wide roof deck flashing tape over all roof sheathing panel seams and cover with #30 felt or equivalent synthetic underlayment.install a self-adhered (peel and stick) membrane over the entire roof deck (recommend a #15 felt bond break between membrane and shingles).Seal the roof deck using one of the following three options, per the IBHS Fortified Hurricane and High Wind Standards:.Enhance roof deck attachment and roof framing attachments, as needed (roof replacement).
