The components of a roof include the rafter framing or trusses, purlins, plywood roof decking, underlayment, and the roof covering.
Image
This home was designed with continuous roof vents and few roof penetrations, allowing more room for the solar shingles that integrate with the asphalt shingles installed to meet IBHS Fortified Roof criteria for increased resistance to high winds and rain
Image
This roof was constructed to meet the IBHS Fortified Roof standard by sealing the decking seams with flashing tape, installing synthetic roof underlayment secured with metal drip edge and nailed every six inches, and using self-adhered starter shingles.
Image
Image

Image
Wrong - This concrete roof was not adequately attached and reinforced and failed in high winds.
Image
Wrong - This roof failed in high winds due to lack of metal attachments to the framing.
Image
Image
Wrong – If roof membrane is not fully adhered, it can flutter and fail due to negative pressure from wind above and positive pressure from air leakage through roof deck below
Image
Image
Wrong – Roof underlayment is not fully adhered and roof deck seams are not sealed so roof is susceptible to high-wind events
Image
Wrong – The clips holding these metal roofing panels were set too far from the roof eave (above red line) and the panels lifted in strong winds
