Commercial Roof Hurricane Prep Guide

31 July, 2024

As hurricane season approaches, it’s crucial for businesses to ensure that their commercial roofs are ready to withstand the fierce storms that can hit. While hurricanes are a natural part of the weather cycle in many regions, the damage they can inflict on commercial properties is anything but predictable. Proper preparation can save businesses from significant financial losses and operational disruptions. Here’s a comprehensive guide on key considerations for preparing commercial roofs for hurricane season.

1. Conduct a Thorough Roof Inspection

Before hurricane season hits, schedule a detailed inspection of your commercial roof. This should be done by a professional roofing contractor who can identify potential weaknesses such as damaged shingles, loose flashing, or compromised seams. Look for the following:

  • Damage to Roof Covering: Check for missing or damaged shingles, tiles, or membranes.
  • Flashing and Sealant Integrity: Ensure that all flashing and sealants around roof penetrations (vents, skylights, etc.) are intact.
  • Gutter and Downspout Condition: Clear any debris and ensure that gutters and downspouts are securely fastened and free-flowing.

2. Reinforce Roof Structure

Strong winds can uplift or damage even the most well-maintained roofs. Reinforcing the structure of your roof can prevent catastrophic failures:

  • Strengthen Roof Decking: Ensure that the roof deck is securely attached to the underlying structure. In some cases, additional fasteners or reinforcements might be necessary.
  • Upgrade Roof Fasteners: Use high-quality, corrosion-resistant fasteners for any roof components, and ensure they are adequately spaced and secured.
  • Consider Impact-Resistant Materials: For new roofs or replacements, consider impact-resistant materials that can better withstand debris and high winds.

3. Secure Roof Accessories

Roof accessories such as HVAC units, antennas, and satellite dishes can become projectiles in high winds. Secure them properly to minimize the risk of them causing damage:

  • Anchor Roof Equipment: Ensure that all rooftop equipment is securely anchored to the roof structure.
  • Protective Covers: Use protective covers or shields to guard against wind and debris damage.
  • Regular Maintenance: Keep roof accessories well-maintained and replace any worn or damaged parts.

4. Evaluate and Upgrade Drainage Systems

Proper drainage is crucial to prevent water accumulation and potential leaks:

  • Clean Drains and Gutters: Regularly clean roof drains, gutters, and downspouts to ensure they are free of debris.
  • Check for Proper Slope: Ensure that the roof has a proper slope to facilitate efficient water runoff.
  • Inspect Flashing Around Drains: Make sure that the flashing around roof drains and other penetrations is in good condition.

5. Implement Emergency Preparedness Plans

Having a plan in place can make a significant difference in how quickly you can respond to damage:

  • Develop an Emergency Response Plan: Outline procedures for handling roof damage and emergency repairs.
  • Train Staff: Ensure that your team is familiar with the emergency procedures and knows whom to contact in case of a roofing emergency.
  • Stock Essential Supplies: Keep a supply of emergency repair materials and tools readily available.

6. Insurance Considerations

Verify that your insurance policy covers hurricane-related damages and that you have the right type and amount of coverage:

  • Review Your Policy: Check the details of your commercial property insurance policy to understand what is covered and any exclusions.
  • Document Roof Condition: Keep detailed records and photographs of your roof’s condition before and after inspections or repairs. This can be helpful for insurance claims.

7. Consider Roof Upgrades

If your roof is aging or showing signs of significant wear and tear, consider upgrading to materials that offer better hurricane resistance:

  • TPO or PVC Roofing: These materials are highly durable and resistant to high winds.
  • Metal Roofing: Metal roofs can provide excellent protection against high winds and flying debris.
  • Impact-Resistant Shingles: If you prefer shingles, opt for impact-resistant varieties that are designed to withstand harsh conditions.

Conclusion

Preparing your commercial roof for hurricane season involves a combination of proactive maintenance, structural reinforcement, and emergency planning. By taking these key considerations seriously, you can significantly reduce the risk of severe damage and ensure your business remains operational even in the face of a storm. As always, consult with roofing professionals to tailor a preparation strategy specific to your roof’s condition and your business’s needs. With the right precautions, you can weather the storm and keep your business safe and secure.
