Roofs in wind.

The cost of the roofs with a wind resistance is higher than the average one. Start with good structural design. Specifically here are five tips that can help you make sure your home has the best roof for high winds. High winds can lift roofing material away or damage it with debris blown from elsewhere.

Low resistance cost about 1 000 dollars extra and the high resistance about 3 000 dollars. The roof is an easy target for one of mother nature s most unpredictable and powerful forces wind. The main concern from florida building code is that any structures or vents that may reside on the flat roof must be properly fastened and sealed. High winds can cause damage to your roof even without hail or other harmful weather.

Your home s floor plan is the first thing to consider. Wind uplift is created when the air pressure below the roofing system is higher than the air pressure above the roof. 6b the roof is of 10 roof slope and out of all the incident wind angles the maximum pressure coefficient is found to be as 0 57 which is less than the maximum pressure coefficient of 0 98 by wind tunnel experimental study and the maximum pressure coefficient of 0 91 by cfd simulation study on pyramidal roof of 10 roof slope without opening as described by roy et al. Strong winds can cause sudden devastating roof damage when a severe storm moves through but asphalt roof shingles can also be negatively impacted on windy days when there s no rain hail sleet or snow in the forecast.

Shingles roofs especially take a beating during high winds despite most being rated to withstand 90 mph winds. There are several types of damage high winds can cause to your roof including leaks missing shingles and gutter problems. In addition metal roofs don t need the periodic costly maintenance that other roofing materials often require. It all depends on the quality of the chosen material and the amount of the resistance against the wind.

Some metal roofs can sustain wind gusts up to 140 miles per hour will not corrode or crack and may be impact resistant depending on which metal you choose. Roof design wind loads are the wind pressures and resulting uplift forces for which the roof structure is designed. An intelligent floor plan can reduce the wind load on the roofing system of your home making it less likely to fail. The most common roofing materials for pitched roofs are asphalt or composition shingles metal slate wood shingles and tile.

Keep in mind that the roofing system includes the surface materials and the fasteners used to attach them to the roof deck. Each has different wind resistance characteristics.
