Strong, persistent winds put roof coverings to the test and can cause devastating and costly damage. This is especially true in Florida, which can be prone to extreme winds during hurricane seasons. As such, choosing the best roof for high winds is crucial for protection against high wind scenarios.
Different commercial building roofing options offer varying degrees of high wind resistance. Some types of roofs, when installed correctly and well-maintained by a reputable roofing contractor, can effectively withstand high winds better than others. Below is a comprehensive look into the best types of commercial roofing for high winds.
Flat Roofing Systems: The Best Roof for High Winds
Flat commercial roofing systems are the best choice if you seek maximum protection from strong Florida winds, among the other benefits they offer. Since a flat roof is nearly level, it experiences less wind resistance, reducing its susceptibility to damage and blow-off.
Nonetheless, the resistance of flat roofs to high winds depends on several factors, including type and quality of roofing materials, quality of roof installation, and maintenance. With flat commercial roof systems, you have several options, including:
Built-up roofing (BUR)
BUR is a popular roofing option that consists of rhythmical layers of asphalt and reinforced fabrics known as roofing felts. BUR commercial roofing systems are particularly wind resistant due to their redundancy.
If a layer breaks off, the remaining layers offer immediate protection. They are also less susceptible to wind uplift and scouring. BUR is also tough and durable and features great membrane strength for proven protection against high winds.
Modified bitumen (Mod Bit)
Modified bitumen roof systems consist of factory-fabricated asphalt layers combined with reinforcements for strength and modified with plastic or rubber for flexibility. Today’s reinforcements include fiberglass, scrims, and polyester, while the primary modifiers are APP and SBS (polymers).
Modified bitumen roofs are installed as two or three-ply systems with sealed seams, thus offering significant protection against strong winds.
Thermoplastic Roofing
Thermoplastic roofing offers durability, flexibility, fire resistance, and easy maintenance. These roofing membranes are made from PVC, and you install them by welding the material seams.
Thermoplastic roofing is great for tackling wind-driven pooling water and hail and offers considerable wind resistance.
While a flat roof is the best for high winds, it’s not foolproof. The quality of installation is an integral part of its overall resistance to strong winds, regardless of the roofing material.
A qualified roofing contractor understands the effects of high winds on different flat roofing systems and knows the best ways to navigate around them.
For instance, correct installation can help minimize aspects such as wind uplift and scouring, which tend to affect flat roofing systems. Proper maintenance is also an important factor affecting a flat roof’s ability to withstand extreme winds.
Metal Roofs: A Great Second Choice
Metal roofs are the next best commercial roofing option for high-wind areas. Metal roofing consists of overlapping panels or shingles fastened to a solid substrate or frame. The most common metals used for commercial roofing purposes include aluminum and galvanized steel. Copper, zinc, and tin may also be used.
Metal is a sturdy and highly durable roofing material that can hold its own against powerful winds when installed correctly. Metal roofing is resistant to wind uplift, which can cause significant roof damage.
Metal commercial roof constructions today feature tight seams and fewer overlaps. This limits the number of places where wind can infiltrate and cause havoc via wind uplift.
Metal commercial roofing systems are also resistant to high impacts and are well-rated for hailstorm protection. As with flat roofing systems, quality craftsmanship is crucial. A high-quality professional installation ensures your metal commercial roofing system performs well when facing strong winds.
Maintenance is equally as important, especially for metal roofs. Professional care involves regular inspections and necessary repairs to address roof performance issues.
