As homeowners, we often take comfort in the shelter of our houses, trusting that they will protect us from the elements. However, when it comes to severe weather events like tornadoes, the vulnerability of our roofs can be a sobering reality. While direct hits from tornadoes are obviously destructive, what many may not realize is that even indirect windstorms associated with tornado warnings can wreak havoc on roofs, particularly those with shingle coverings.
Shingle roofs, ubiquitous in many residential areas, are especially susceptible to damage from high winds. Unlike metal or tile roofs, which may offer better resistance, shingle roofs can suffer significant harm even from winds that don't directly hit them. Let's delve into why shingle roofs are vulnerable and what homeowners can do to mitigate the risks.
The Fragility of Shingle Roofs
Shingle roofs consist of overlapping layers of individual shingles, typically made from materials like asphalt or fiberglass. While they provide adequate protection under normal weather conditions, they can be easily compromised by strong winds, especially when those winds create uplift forces.
During an indirect windstorm associated with a tornado warning, the wind patterns can become erratic and turbulent. Even if the tornado itself doesn't touch down, the surrounding winds can still reach high speeds and change direction suddenly. These turbulent winds can create upward pressure beneath the shingles, causing them to lift, crack, or tear away from the roof deck.
Additionally, shingles can become brittle over time due to exposure to sunlight, temperature fluctuations, and other environmental factors. This brittleness makes them more prone to damage from high winds, as they are less flexible and more likely to break upon impact.
Common Types of Damage
Indirect windstorms associated with tornado warnings can cause various types of damage to shingle roofs:
1. Shingle Loss:
High winds can lift shingles and tear them away from the roof, leaving the underlying structure exposed to the elements.
2. Shingle Creasing:
When strong winds can cause shingles to bend up and down, creating ridges. The singles may also push against each other, causing creases in the upper shingle.
3. Shingle Damage:
Flying debris carried by the wind can impact shingles, causing cracks, dents, or tears. Once damaged, shingles are less effective at repelling water, increasing the risk of leaks and water damage inside the home.
4. Loosening of Fasteners:
The force of the wind can loosen the nails or adhesive strips that hold the shingles in place, compromising the integrity of the entire roof system.
5. Granule Loss:
High winds can strip away the protective granules on the surface of asphalt shingles, reducing their durability and lifespan.
Mitigating the Risks
While it's impossible to completely eliminate the risk of damage to shingle roofs during severe weather events, there are steps homeowners can take to reduce the likelihood and severity of damage:
1. Regular Inspections:
Conduct routine inspections of your roof to identify and address any signs of wear and tear before they escalate into larger issues.
2. Reinforcement:
Consider reinforcing your roof with additional fasteners or adhesive to improve its resistance to uplift forces.
3. Trimming Trees:
Trim back overhanging branches that could potentially damage your roof during a windstorm.
4. Upgrading Shingles:
Invest in high-quality, impact-resistant shingles that are designed to withstand strong winds and flying debris.
5. Professional Installation:
Ensure that your shingles are installed properly by hiring experienced roofing professionals who follow manufacturer guidelines.
