How Roofs are Damaged by Wind

How Roofs are Damaged by Wind

The highest wind speed ever recorded in Florida occurred on Labor Day in 1935 when sustained winds blew at 185 miles per hour. While it is very unlikely that very many roofs were not damaged on that day, there are many different factors that determine how well your roof survives the next wind event. Learning about these factors may help you plan a roof that will sustain little wind damage.

Wind Speed

Generally, most roofs are not damaged by sustained winds under 45 miles per hour. Winds over that speed can start to do damage if your roof is not in great condition. Winds over 58 miles per hour have removed three-tab shingles while winds over 75 miles per hour can do severe damage. Normally, the first areas of the roof to suffer damage are corners and valleys. You can help prevent some roof damage by making sure that the roof is properly secured to the lower part of the home and by designing a roof allowing the wind to go up and over your home’s structure. Adding reinforcements in gable areas can help lower wind damage to roofs.

Type

Some types of roofs suffer wind damage easier than others. Generally, single-tab and three-tab asphalt shingles will suffer wind damage sooner than other roofing choices. Architectural fiberglass shingles are a great choice for those who need to stay within a lower budget. The State of Florida Division of Emergency Management proved that cement s-shaped tiles were able to withstand windspeeds up to 120 miles per hour and hail up to 1-inch diameter without suffering any damage. Clay roofing can withstand winds up to 125 miles per hour.

Age

Older roofs generally suffer more damage than roofs put on more recently because older roofs become more brittle. Many insurance companies require homes with roofs older than 15 years to get a roof inspection before their insurance will be renewed. Furthermore, many companies will prorate the value of a roof that is older than 20 years. Therefore, if you put on a roof that is supposed to last 40 years, but you need to replace it after 20 years, you will only get 50 percent of the cost to replace your roof.

Location

The location of the roof can make a big difference. While you will want to keep all your trees trimmed back from your roof, you cannot always control what flies from your neighbor’s property during a high-wind event. Nevertheless, try to fasten down any heavy or large objects that might end up on the roof that you own.
