How Strong Does Wind Have to Be to Damage Roof Shingles: 6 Key Indicators

An important factor to consider when evaluating the condition of your roof is the impact of wind. Wind can cause damage to shingles, especially those that are older or in poor condition. Wind speeds as low as 40–50 mph can cause issues, while higher speeds can lead to severe damage or even the removal of the roof.

In this article, we will scrutinize the relationship between wind speed and the likelihood of damage to asphalt shingle roofs, examine signs of wind damage, and explore best practices for safeguarding your roof from such issues.

Understanding the Effects of Wind Speed on Roof Shingles

To understand how wind speed affects roof shingles, one must look at the roof’s age and condition. Wind speeds of 40–50 mph can already cause damage to asphalt shingle roofs, especially if they are older or in poor condition. However, it’s usually when wind speeds reach at least 75 mph that significant damage to a roof occurs. In fact, wind speeds over 100 mph are more likely to cause substantial damage, including the complete removal of a roof.

There are several signs that indicate wind damage to a roof. These include missing shingles, peeling shingles, curling shingles, slightly raised shingle edges, narrow lines near the shingle edges, scratch marks across the roof field, and damaged ridge or soffit vents. These signs serve as visual cues for homeowners to assess the condition of their roofs after a strong wind event.

The age of a roof can also have an impact on its ability to withstand strong winds. Older roofs may be more susceptible to wind damage due to wear and tear over time. Therefore, homeowners with older roofs should exercise extra caution and consider regular inspections and maintenance to guarantee that their roofs can withstand windy conditions.

In areas prone to tornadoes or hurricanes, it might be wise to opt for a metal roof. Metal roofs are known for their durability and ability to combat high winds. They can withstand wind speeds of up to 140 miles per hour, providing homeowners with an added sense of security during severe weather events.

6 Key Indicators of Wind Damage on Roof Shingles

1. Missing Shingles

If you notice missing shingles on your roof after a strong wind event, it’s a clear indication of wind damage. Missing shingles expose the underlying structure of the roof, leaving it vulnerable to water leaks and further damage. You’ll need to address this issue promptly by replacing the missing shingles to maintain the integrity of your roof. Remember to use matching shingles to ensure a seamless appearance and proper protection.

2. Peeling Shingles

Peeling shingles are another sign of wind damage. When shingles start to lift or peel, it compromises their ability to protect your roof from moisture and other elements. If you come across peeling shingles, you might want to have a professional roofer assess the extent of the damage and recommend appropriate repairs. Ignoring this issue can lead to more severe problems, such as leaks and rotting wood beneath the shingles.

3. Curling Shingles

Curling shingles, where the edges of the shingles turn upward or downward, can indicate wind damage as well. This curling effect can compromise the shingle’s ability to provide a secure barrier against water infiltration. If you notice curling shingles on your roof, it’s essential to address them promptly. A professional roofer can determine whether the shingles can be repaired or if replacement is necessary.

4. Slightly Raised Shingle Edges

When wind exerts force on roof shingles, it can cause the edges of the shingles to lift slightly. While this may seem like a minor issue, it can still lead to water penetration and subsequent damage. If you observe slightly raised shingle edges, you might want to have them inspected by a professional roofer. They can assess the extent of the lifting and recommend appropriate repairs to prevent further complications.

5. Narrow Lines Near Shingle Edges

Narrow lines near the edges of the shingles, often referred to as “crease lines,” can be an indication of wind damage. These lines occur when the wind exerts pressure on the shingles, causing them to bend or fold slightly. While these lines may not always lead to immediate leakage, they weaken the shingle’s integrity over time. It’s essential to address this issue by having a professional roofer evaluate the affected area and determine if any repairs or replacements are necessary.

6. Scratch Marks Across the Roof Field

Scratch marks across the roof field can provide evidence of wind damage. These marks occur when debris or other objects carried by the wind come into contact with the roof surface, leaving visible scratches or scuff marks. If you discover scratch marks on your roof, it’s recommended to have a professional roofer inspect the area thoroughly. They can assess the extent of the damage and recommend appropriate measures to prevent further deterioration.

The Influence of Roof Age on Wind Damage Potential

The age of a roof can play a significant role in its susceptibility to wind damage. Over time, roofs naturally experience wear and tear, making them more vulnerable to the impact of strong winds. Older roofs may have weakened shingles, compromised structural integrity, or deteriorated fasteners, all of which can increase the risk of wind-related damage.

For example, shingles that have become brittle or lost their flexibility due to aging are more likely to crack or break when exposed to high winds. Older shingles may have deteriorated adhesive seals, making them more prone to lifting or tearing off by strong gusts.

Therefore, homeowners with older roofs should be particularly mindful of the potential effects of wind and consider regular roof inspections and maintenance to verify their roofs are in good condition and able to withstand windy conditions.
