Asphalt shingles are one of the most popular roofing materials in the United States due to their affordability, durability, and versatility. However, they are not immune to the effects of wind damage, which can compromise the integrity of the shingles and lead to leaks, water damage, and even structural issues. In this blog post, we will discuss the causes and signs of wind damage to asphalt shingles and what homeowners can do to prevent and address this problem.
Causes of Wind Damage to Asphalt Shingles
Wind damage to asphalt shingles can be caused by a number of factors, including:
- Age: As asphalt shingles age, they become more brittle and prone to cracking, breaking, or lifting in high winds.
- Installation: Improper installation of shingles, such as using too few nails, inadequate sealing, or improper ventilation, can make them more susceptible to wind damage.
- Wind speed: The higher the wind speed, the more likely it is that shingles will be damaged or blown off.
- Direction of wind: The direction of the wind can also play a role in the type of damage that occurs. For example, if the wind is blowing in a direction perpendicular to the roof edge, it can cause shingles to lift or curl, while winds that blow parallel to the roof can cause shingles to break or tear.
Signs of Wind Damage to Asphalt Shingles
Homeowners can look for the following signs of wind damage to asphalt shingles:
- Missing or cracked shingles: High winds can cause shingles to be blown off or cracked, leaving the roof vulnerable to leaks and water damage.
- Curling or lifting shingles: Strong winds can cause shingles to lift or curl at the edges, exposing the roof deck and making it more susceptible to water damage.
- Granule loss: Wind damage can cause the granules on shingles to be dislodged, which can reduce the shingles’ ability to protect the roof from UV rays and water damage.
- Leaks: Wind damage to shingles can create gaps and spaces that allow water to seep into the roof and cause leaks.
Preventing and Addressing Wind Damage to Asphalt Shingles
Prevention is the best way to avoid wind damage to asphalt shingles. Homeowners can take the following steps to prevent wind damage:
- Choose the right shingles: When selecting asphalt shingles, homeowners should choose those that are rated for high-wind speeds and that have been tested to withstand wind damage.
- Proper installation: Shingles should be installed properly by a licensed and experienced roofing contractor. This includes using the correct number of nails, adequate sealing, and proper ventilation.
- Regular maintenance: Regular roof inspections and maintenance can help identify and address potential wind damage before it becomes a major problem.
If wind damage has already occurred, homeowners should take action to address it as soon as possible to avoid further damage. This may include repairing or replacing damaged shingles, sealing gaps and spaces, and addressing any underlying structural issues that may be contributing to the problem.
Wind damage is a common problem for asphalt shingle roofs, but with the right preventative measures and prompt action when damage occurs, homeowners can ensure the longevity and integrity of their roofs. If you suspect wind damage to your asphalt shingle roof, contact a licensed roofing contractor to schedule an inspection and address any issues that may be present.
