A guide identifying and rectifying roof damages caused by windy storms.
A storm that produces no rain or hail can still damage your roof; strong winds can be just as bad a destroying force. Roofs are designed to resist typical winds, however, high winds can create stress points on a roof. These gusts can weaken your roof over time. Replacing missing shingles and fixing initial roof damage quickly is important to prevent further damages such as water leaks and rising energy costs that will result from a compromised roof system.
How Wind Damages Your Roof
The pattern in which wind flows over a roof is not uniform. Certain areas can be more susceptible to higher wind pressures, such as the corners and perimeters. Other areas like the center of the roof are likely to experience wind gusts at lower pressures. Most wind damage starts at the roof's edge. However, anywhere where there is loose roofing material, there is risk for damage. If the wind is able to get below it and push up, the wind can grab more next time and create a chain-like peeling effect. This type of damage usually starts small, but continues to grow over time through repeated exposure.
Once a section of your building's roof is stripped of its protective barrier, water will be able to leak into the building, which can cause mold, rot, staining, and a slue of other undesirable conditions. Homeowners can avoid this type of wind damage by always making sure the corners and edges of their roofs are secure and in good condition.
Flying Debris and Tree Damage
Wind storms also have the potential to move debris which can end up on your roof. Tree branches and other debris can sometimes be more damaging than the wind itself. Inspect your roof after a wind event. Check to see if anything has landed on your roof and in your gutters. If you have any trees near your roof, make sure the branches are trimmed far enough away as to not scratch and tear the roof during windy storms. Falling branches from overhead trees can puncture and damage shingles and other roofing materials.
What to Look for When Inspecting Your Roof for Wind Damage
Perform an outdoor inspection of your roof. Look for missing and damaged shingles. If the damage is localized, a roof repair may be able to address the problem. More widespread damage might require a roof replacement. Be sure to take a look at the chimney and ventilation pipes, as well as flashing and gutters to ensure all are secure. If you suspect your roof may be damaged, consider the type of roofing materials on your roof to determine what type of damage your roof has endured.
Damage to different types of roofs and roof elements will look different. Damaged composite shingles can curl, lose granulation, break, or tear off, whereas wood shingles can appear moldy, decaying, splitting, or curling. Flat roofs will have obvious patches, cracks, tears, and blistering if the wind has taken its toll. If you see any flashing that appears to be torn, buckled or bent, you have a problem on your hands. Be on the look out for crumbling roofing cement, loose soffits and fascia. These roof elements can be an indicator of damage. When looking at your chimney be aware of any cracked bricks, caps, and flashing. If you notice any bending or sagging gutters, inspect them as well as the areas of the roof near them.
Perform an indoor inspection. Look for moisture marks on walls and ceilings, and peeling paint, as these are indicators of a leaking roof. Look for damp rafters and leaks in the attic.
Call a professional. Getting on your roof is not recommended as it can lead to personal injury or injury to personal property. A trained professional has the tools and knowledge to be safe while on the roof.
What to Do Next if Damage is Present
Get it fixed immediately! The roof is an important barrier which protects the house from the eroding effects of outside elements. If you notice your house has sustained wind damage, your best option is to get it fixed as soon as you can to prevent further damages. Contact your insurance agent and they will determine whether or not to file a claim. Thoroughly document damages, and keep receipts (whether you did the work or you hired someone) as many insurance companies will cover these expenses when submitted with a claim.
