Whether homeowners live in hurricane-prone areas or not, wind is a residential roof's biggest threat, causing $9 billion of damage each year and affecting 60 percent of homes across the country. To keep homes safe during hurricanes and devastating wind storms, the roofing industry has spent the past decade developing better wind-resistant materials. Fortunately, these new building techniques, retrofitting practices and improved materials can be incorporated into existing roofs and re-roofing projects by trusted Charleston roofing experts.

One of the most destructive forces during hurricanes, tropical storms and tornadoes is wind uplift, which causes the majority of roof failures. This danger is especially strong at the roof's edges and in spots where the roofing material is not securely attached to the structure.

Consumers who are re-roofing their homes can find out how well their prospective shingles resist wind and uplift by checking their labeled ratings. Shingles that offer the least wind resistance are rated as Class A for 60 mph winds. Class D shingles can resist winds up to 90 mph, and Class F shingles are wind-resistant at 110 mph. The highest rating is Class H, which signifies wind and uplift resistance at 150 mph.

If the consumer is re-roofing and wind safety is an issue, the roofer will most likely tear off the old roof entirely. This allows the consistent application of highly wind-resistant materials and creates a more uniform, intact surface. Roof edges will be sealed with metal drip edges to prevent wind-driven rain from damaging soffits and eaves. Shingles will overlap horizontal flashing and will be adhered with a special cement. Even the number of nails used to secure the shingles, the nail placement and the method of nail application are governed by wind-resistance standards.

Homeowners who aren't ready for new roofs may want to consider some proven retrofit measures to ensure roof safety during wind storms. To increase wind uplift resistance that is three times stronger than traditional roofs, experienced roofers apply a quarter-inch strip of wood adhesive where the roof deck meets the trusses and supports. Hurricane straps are attached to secure the roof to the building foundation. Overhangs are minimized or reinforced, and gable-end walls are braced.

Whether consumers are considering re-roofing or retrofitting, it's always best to address roofing issues early. Calling in a qualified roofer to handle the job before storm season hits allows homeowners to concentrate on other last-minute preparations and finding a safe place to wait out the storm.
