The roof deck should be well attached to the rafters or trusses. Inspect these connections when the old roof cover and underlayments are torn off. It will be easier to see the spacing of the fasteners attaching the roof deck to the roof framing below and to install additional nails to strengthen the roof deck uplift connection.
During extreme weather events, the roof is one of the most vulnerable areas of a home. However, many roofing materials are not strong enough to withstand harsh weather conditions. More homeowners are turning to metal roofing to protect their homes and prevent costs like repairs and damages.
Metal roofing has a 140-mph wind rating, meaning it can withstand wind gusts up to 140 miles per hour. Metal roofing materials interlock, forming a protective barrier that other roofing materials do not provide. These interlocking tiles make metal roofs stronger and more resistant to high winds.
Under high wind conditions, says architect Jim Mitchell, "Metal roofing systems have wind resistance and uplift resistance that is above the new building code requirement. That gives us a sense of relief in that we can use the best material to meet those criteria."
