Hailstorms can cause severe damage to commercial roofs, especially in regions where hail is frequent. However, by choosing the right materials, installation techniques, and conducting regular inspections, you can significantly reduce the risk of costly damage. Here’s how to safeguard your roof:
Understand Your Risk
Your geography plays a critical role in determining the likelihood of hail damage. Areas prone to frequent hailstorms require a proactive approach to roof protection. Using hail risk maps or consulting local weather data can help you understand your building's vulnerability and plan accordingly.
Choose the Proper Roofing Membrane
The type of roofing membrane you select makes a difference in hail resistance:
PVC membranes are excellent for chemical resistance but are more prone to cracking and fracturing as they age, especially under hail impact.
TPO membranes are firmer and less likely to fracture, making them the recommended choice in hail-prone areas. Whether for a new roof, reroof, or recovery project, TPO is often the best option for long-term durability.
Select a Thicker Roofing Membrane
Opting for a thicker roofing membrane is a worthwhile investment. While a 60-mil TPO membrane is standard, upgrading to an 80-mil TPO membrane offers increased resistance to hail impact, a prolonged lifespan, and has a longer manufacturer warranty. Though it involves a higher upfront cost, the added durability can save you from significant repair expenses down the line.
Install a Cover Board
A high-density cover board, such as 1/2-inch DensDeck, adds a rigid layer beneath your roof membrane, protecting it from hail impacts. This additional layer absorbs and distributes the force of hail, reducing the risk of punctures or damage. Cover boards can be installed during new roof construction, reroofing, or recovery projects. Skipping this step, especially in hail-prone areas, can leave your roof vulnerable.
Get Your Roof Inspected
Even if there’s no visible damage after a hailstorm, your roof may still be compromised. Professional inspections are crucial to identifying hidden issues like weakened membranes or damaged insulation. Hail damage can take years to fully manifest, so addressing problems early can save you from costly surprises later.
