Commercial roofs are built to withstand a lot, but even the toughest roofing systems aren’t immune to wind damage. Strong gusts can create problems ranging from minor shingle shifts to catastrophic roof failure, compromising your building’s structure and exposing it to leaks and other issues. In this post, I’ll walk you through how to spot wind damage early, ways to prevent it, and what steps you can take if it occurs.

Understanding Wind Damage: Why It Happens

Wind damage often begins at the most vulnerable points of a roof—such as edges, corners, and seams—where gusts can loosen roofing materials. Once a small piece is compromised, the wind gets under the surface, tearing larger sections away. Here are key factors that determine your roof’s vulnerability to wind:

1. Roof Age: Older roofs lose durability over time, making them more prone to wind damage.
2. Roof Type: Flat roofs may experience “uplift” pressure, while sloped roofs are more susceptible to shingle lifting.
3. Installation Quality: Poor installation leaves gaps and weak spots that wind can easily exploit.
4. Building Height and Location: Taller buildings and those in open areas are more exposed to high wind pressures.

Signs of Wind Damage on Commercial Roofs

Early detection is crucial to prevent minor issues from escalating into expensive repairs. Here’s what to watch for:

1. Lifted or Torn Materials: Look for shingles, metal sheets, or membrane seams that appear loose or out of place.
2. Debris on Roof Surface: Accumulated debris can block drainage systems and indicate nearby wind damage.
3. Visible Gaps or Open Seams: Gaps in roofing materials can let water in, leading to internal damage.
4. Damaged Flashing: Flashing around vents, chimneys, and skylights may be bent or missing.
5. Interior Leaks or Water Stains: Wind damage can lead to leaks, which often show up as ceiling stains or water drips.

Preventing Wind Damage on Your Commercial Roof

Prevention starts long before the wind begins to blow. These steps will help you reduce the chance of damage:

1. Routine Inspections
   Schedule regular roof inspections, especially before and after storm seasons. Inspections help catch small issues before they turn into bigger problems.
2. Reinforce Edges and Flashings
   The edges of your roof are the most vulnerable. Ensure all flashings and fasteners are secure to prevent wind from getting under the surface.
3. Clear Debris Regularly
   Keep your roof free of loose debris that could get blown into drainage systems or puncture the roof surface.
4. Invest in Wind-Resistant Materials
   Use roofing materials designed to withstand high winds, such as impact-resistant shingles or heavy-duty membranes.
5. Maintain HVAC Equipment and Skylights
   Secure any rooftop equipment like HVAC units, skylights, and vents, which could shift or cause damage in high winds.

Steps to Take After Wind Damage

If wind damage occurs, it’s crucial to act quickly to prevent further issues:

1. Document the Damage
   Take photos of any visible damage, both on the roof and inside the building. This documentation is essential for insurance claims.
2. Contact a Roofing Professional
   Reach out to a roofing contractor, like us at Right Now Roofing, for a full inspection. We’ll identify hidden damage and provide a detailed report.
3. Make Temporary Repairs
   If you find any leaks, use a tarp to cover the affected areas temporarily until repairs can be made.
4. File an Insurance Claim
   Submit your documentation to your insurance provider as soon as possible. Make sure you understand your policy coverage to maximize your claim.
5. Plan for Permanent Repairs or Replacement
   Depending on the extent of the damage, we’ll recommend either targeted repairs or a full roof replacement to restore your roof’s integrity.

FAQs: Common Questions About Wind Damage on Commercial Roofs

1. How much wind can a commercial roof withstand?

Most commercial roofs are designed to withstand wind speeds between 90 and 150 mph, depending on the materials used and local building codes. However, the quality of installation and ongoing maintenance play significant roles in how well the roof performs.

2. How often should I inspect my commercial roof for wind damage?

We recommend inspecting your roof at least twice a year—once before storm season and again afterward. Additional inspections should be done after major storms or high-wind events.

3. Does insurance cover wind damage to commercial roofs?

Most commercial property insurance policies cover wind damage. However, it’s important to review your policy details to understand deductibles and coverage limits.

4. What types of roofing materials are best for wind resistance?

Metal roofing, impact-resistant shingles, and heavy-duty membranes are among the best materials for wind resistance. These materials provide enhanced durability in high-wind conditions.

5. Can wind damage lead to leaks?

Yes, wind can loosen or tear roofing materials, creating openings where water can enter. Even minor wind damage can lead to significant leaks over time if left unaddressed.
