The roof serves as an important protective layer for your commercial establishment. It protects your employees, customers, and equipment from the winter chill, the downpour during wet months, and the heat of the sun.

Extreme weather conditions, however, can threaten the durability of your roofing system. It’s a good idea, therefore, to learn how these natural forces affect your roof, so you know what issues to look out for during a maintenance check.

Here are a few weather conditions that can undermine your roof’s stability.

Heavy Rain

Something as common as rain can be detrimental to the durability of your roof. A heavy downpour infiltrates the weakest spots and compromises the overall structure.

It may also result in moisture damage. This happens when rainwater accumulates on an area of your rooftop.

Additionally, long-term rainfall doesn’t give your roof enough time to dry properly. It could weaken the structural integrity of the shingles and tiles.


Hail is worse than rain.

One good storm causes widespread damage, especially if your commercial building is in a climate that gets unfavorable hailstorm weather conditions.

Fast-hitting hailstones, for instance, can damage your shingles by tearing away their underlay.

Extreme Heat

Scorching heat causes premature aging, which damages both your roof’s interior and exterior. Prolonged exposure to this heat can destroy certain roofing materials.

Tiles and shingles, for instance, tend to shrink, curl, wrap, or crack under blistering temperatures.

Strong Winds

Windstorms, such as hurricanes and tornadoes, are dangerous for your roof.

Powerful winds can tear away your roofing materials, especially when they’re loose or old.

On top of that, strong windstorms can hurl tree branches and other destructive debris, as well as cause tears and punctures on the rooftop.

Snow and Ice

Snow, in some ways, may not look like a major problem on your roofing system. It can serve as a barrier for protection. Plus, it takes large amounts of snow to cause a roof collapse.

Unfortunately, it becomes a problem when the snow melts.

Melted snow trickles down the slope, refreezes, and turns into ice dams. These ridges of ice can force water through the shingles and cause leaks, wear down fragile roof materials, damage the insulation, soak the ceiling, and compromise the structure of your commercial establishment.

Since snow tends to cover any visible damage, you may not notice any roofing problems until you begin seeing leaks.

While these weather conditions are unavoidable, fortifying your roofing system will help minimize the damage.

You can give your roof added protection from the elements with the help of A & L Foam Insulation, Inc. We use Spray Polyurethane Foam (SPF) to create an insulated barrier to your roofing system.

And when replacement becomes necessary, you won’t need to get rid of the entire roof. You can have the small, damaged roof sections taken out, and then have SPF reapplied to the affected section.

Reach out to us to learn how our SPF helps resolve any building, insulation, or roofing issues you might currently have.
