Commercial Roofing Hail, Snow & Storm Damage
It’s a business owner’s nightmare. A strong storm rolls through and brings damaging hail or heavy snowfall. Cleanup hassles, insurance inquiries, building inspections and repairs need to happen. Business operations could slow or stop. It’s a headache – you want to avoid the trouble.
Roofing is always a vulnerable target, so choosing the right commercial roofing material is a critical decision. Here at Roofed Right America, we’ll help you make the right choice for your roofing needs.

Types of Commercial Roofing
Roofed Right America offers four types of commercial roofing materials:
These options vary in functionality, but the good news is Roofed Right America’s experts make the selection process smooth.
Roofed Right America’s experts offer some of the toughest materials available with energy-saving benefits. Our crews are experts at metal roofing jobs and don’t shy away from the tough work. Insurance companies sometimes offer reduced rates for a building’s metal roofing because of the metal’s durable qualities.
It’s hard to beat the quality and longevity of metal roofing. We have the design capabilities to make your metal roof look outstanding, too.
Benefits and Problems of Metal Roofing for Hail
It’s intuitive that metal roofing offers some of the best protection against hail damage. It’s a strong, reinforceable material. Still, metal roofs can be dinged or dented during large hail events – luckily, those types of damages are easily repaired. Hail punctures are far less common, especially when dealing with larger gauge metals.
The benefits of metal roofing for hail protection far outweigh the drawbacks (which are few to none).
Benefits and Problems of Metal Roofing for Snow
A strong blizzard can dump feet of snow within a short period of time. It’s a common worry for commercial and industrial structures alike. Dampen the concern with a metal roof. Benefits of metal roofing for snow include:
Resistance to snow accumulation.
Unlike asphalt roofs, many metal roofs usually don’t need to be shoveled off. The slippery surface of the metal is less likely to become stuck with snowfall. However, many commercial buildings are low-slope or flat-surfaced, which makes this benefit less effective than in residential structures.
- Angled roofs that shed snow create a hazard for anything below. Luckily, metal roofs can be equipped with guards against these “avalanche” events.
Improved energy retention.
If it’s snowing, it’s cold. Metal roofs – when properly designed and installed – catch heat energy before it escapes. Rooms stay warmer and snow melts faster.
Modified Bitumen Roofing
Modified bitumen roofing provides great protection from regular roofing wear-and-tear, including hail and snow damage. With an asphalt base mixed with plastic or rubber, modified bitumen roofing is durable yet flexible.
Designed for “flat” roofing concepts, modified bitumen roofing is often an ideal choice for large commercial structures. The layered, tried-and-true concept of modified bitumen roofing is capable of handling a host of environments.
Benefits and Problems of Modified Bitumen Roofing for Hail
Typically, only large hail – about 2.25” in diameter or larger – can cause damage to modified bitumen roofing.
Larger hail may cause:
- Blunt-force damage to surface granules
- Impact depressions
- Cracks in reinforcement mats
- Delaminated membranes
In most cases, the top layer of modified bitumen roofing is adequate protection for the lower layers.
Benefits and Problems of Modified Bitumen Roofing for Snow
Modified bitumen roofing is one of the most dependable roofing materials. It is relatively easy to install, maintain, replace and repair. Because of its durable layered design, modified bitumen roofing is a great choice for commercial buildings affected by heavy snowfall. The modified bitumen roofing may need to be shoveled during heavy snowfall events to protect against degradation or collapse.
PVC roofing, or polyvinyl chloride roofing, is a common roofing material for flat-surfaced commercial and industrial buildings. Because the material is puncture-resistant and watertight, PVC roofing is another great option if you live in a state where heavy snowfalls and hail storms occur.
Benefits and Problems of PVC Roofing for Hail
Medium-sized hail has difficulty puncturing the PVC roofing membrane. PVC is extremely waterproof, so the chances of a leak occurring during a hail or snowstorm are small. Much of PVC roofing’s hail resistance has to do with the hardness of the supporting surface below it – the harder the surface, the more impenetrable the PVC roofing is.
However, PVC roofing can crack due to large hail strikes. Water can fill those cracks and increase their size due to freeze/thaw cycles, especially if you haven't maintained your PVC roof properly.
Benefits and Problems of PVC Roofing for Snow
Snow does not affect PVC roofing to any great extent.
They are designed for a variety of weather conditions and stand up well over an extended period of time. However, quality installation is crucial – poor PVC roof seaming leads to expensive rewelding.
TPO (thermoplastic polyolefin) roofing materials are made of rubber and are commonly used for flat-roofed commercial buildings. The white surface of TPO roofing also comes with cost-saving benefits – UV rays bounce off the roof. It should be noted that some studies indicate TPO roofing tends to be susceptible to weathering when it’s exposed to high-heat UV rays.
Benefits and Problems of TPO Roofing for Hail
TPO roofing materials are single-ply, meaning they’re weaker than many other material options. Newer TPO roofs stand up to hail damage better than older roofs, so it’s important to check older roofs and schedule a replacement when necessary.
Benefits and Problems of TPO Roofing for Snow
Snow generally shouldn’t have an effect on a TPO roofing membrane, but it’s important to keep excess weight off the roof by shoveling. If the material has prior damage, water leaks could occur in the damaged areas.
