Metal is often regarded as one of the most hurricane-resistant commercial roofing materials. With styles including standing seam panels, interlocking shingles, and various color coatings, metal roofing combines strength and storm resistance in a sleek, modern aesthetic.

Key Storm Advantages of Metal Roofing:

• High Wind Resistance: Properly installed metal roofs can withstand wind speeds up to 140-180 mph, depending on the material and installation.
• Durability: Metal is resistant to cracks and splits, which can be common with other roofing materials under stress. However, metal can sustain surface-level dents if hit hard enough with debris.
• Fire and Water Resistance: Metal roofing is non-combustible and provides excellent waterproofing.

Metal roofing requires precise installation to ensure that panels or shingles are securely fastened. Incorrect installation can lead to leaking and uplift during high winds, making professional expertise essential. It is also worth noting that metal roofing material may cause extra noise during storms; however, this is rarely a concern because commercial buildings are typically unoccupied during an active hurricane. 

3. Built-Up Roofing (BUR)

Built-up roofing (BUR) is another option frequently used for low-slope roofs in areas that face storm damage. This system consists of alternating layers of bitumen (asphalt or tar) and reinforcing fabrics, topped with a gravel layer or other protective coatings.

Key Storm Advantages of Built-Up Roofing:

• Multi-Layered Durability: The layered construction adds strength and resilience against wind and water.
• Impact Resistance: The gravel top layer provides some protection against flying debris.
• Waterproofing: The layered system offers excellent waterproofing capabilities.

While BUR is a durable choice, it is a heavy system. Proper structural composition and professional installation are critical to ensure it doesn't compromise the building's integrity during a hurricane.

5. Thermoplastic Olefin (TPO) Roofing

TPO roofing is a single-ply membrane roofing material often used on commercial and residential flat roofs. Its light color reflects sunlight, reducing heat absorption for an eco-friendly solution; however, TPO also holds up well in storm-prone areas.

Key Storm Advantages of TPO Roofing:

• Wind Resistance: TPO membranes are durable and can resist high wind speeds when properly installed.
• Waterproofing: The material's seamless installation helps prevent leaks.
• UV Resistance: Its reflective surface resists UV degradation, prolonging its lifespan.
• Cost-Effectiveness: TPO is an affordable option compared to other hurricane-resistant materials.

As with other roofing systems, professional installation is crucial to ensure your TPO roof performs effectively during hurricanes and other extreme weather events.

The Reality of Hurricane-Resistant Roofing

While any of these commercial roofing materials can enhance your building's ability to withstand a hurricane, it's important to note that no roofing system is completely hurricane-proof. The intense forces of a category 4 or 5 hurricane can damage or displace even the most durable materials. However, you can help prepare your building and minimize or prevent damage with a few key considerations:

1. Professional Installation: Always hire licensed and experienced roofing professionals who understand the unique challenges of your region.
2. Regular Maintenance: Routine inspections, cleanings, and minor repairs can prevent small issues from becoming major problems, leaving you vulnerable to storm damage. 
3. Reinforcements: Consider asking your roofing professionals about hurricane ties, straps, or fasteners to strengthen your roof's attachment to the building structure.
4. Necessary Replacement: Over time, even the most well-maintained roofing materials can become weathered, oxidized, torn, or otherwise compromised. Replacing aged roofing components or your entire roofing system when it reaches the end of its lifespan can help better protect your building from storm damage.
