Top Causes of Commercial Roof Storm Damage and How to Address Them

commercial roof hail damage

Storms can be a commercial property killer. Just one significant weather event can result in leaks, weakened materials, and unexpected repair bills. Some damage is evident, but some remains concealed and is not discovered until water begins to pour into the residence.

By learning about the top causes of roof damage, property owners can take measures sooner to mitigate damage and avoid costly repairs in the long term. The earlier a problem is resolved, the more successful you will be at protecting your building and maintaining the flow of business.

The Importance of Acting Quickly After Storm Damage

Commercial roofs are designed to withstand fluctuating weather, but if storms occur too many times, even the strongest systems can give out. Risks from heavy rain, hail, strong winds, and debris become compounded when ignored.

Ignoring early signs of warning may cause:

  • Interior leaks
  • Damaged insulation
  • Mold growth
  • Structural concerns
  • Higher repair expenses

This is what makes the timeliness of action after a storm important. Major roofing problems start small and become major headaches.

Hail Damage Is More Serious Than You Think 

There are several causes of roofing trouble, and hailstorms are among the most common. When the roof looks good from ground level, damage may already be lurking beneath the surface.

Hailstones capable of denting metal roofing, cracking protective coating, or puncturing the membrane can occur. All these damaged places create an entryway for moisture over the years to come, which leads such locations to failure and causes damage to the entire roofing system.

Hidden commercial roof hail damage happens with many commercial buildings, and property owners do not discover it until indoor leaks start to form.

Dealing With Damage Due To Hail

Fast action after a hailstorm saves expensive repairs down the line.

Recommended steps include:

  • Schedule a professional roof inspection
  • Take photos of the damage for insurance
  • Repairs to cracks and punctures
  • Consider impact-resistant materials for roofing

Due to the fact that most of the damage is not instantly visible, a professional assessment is required.

Wind Forces and Upliftment of Roof Materials

High winds tend to loosen or rip away roof materials. During extreme weather, ventilation flashings and roof edges/ seams are particularly mush sensitive.

Never mind that when the wind lifts even a portion of the roofing system, it is very easy for rainwater to be brought under what is left. This triggers a domino effect of moisture damage and destruction.

One of the most common causes of commercial roof storm damage is high winds, but they are even more damaging on old or improperly maintained roofs.

Dealing with Wind Damage

Never ignore wind damage.

Property owners should:

  • Inspect roof edges after storms
  • Promptly replace any missing or loose materials
  • Reinforce weak seams and flashing
  • Secure rooftop equipment and attachments

Regular inspections and maintenance enhance the roof’s resistance against windstorms.

Drainage and Standing Water Issues

Drainage systems also fail during heavy rain, turning the disaster into a minor one.

Drains, gutters, and the correct slope allow water to flow away from commercial roofs. When debris clogs these systems, water starts to accumulate on the stones at the roof’s surface.

The weight of standing water also exerts pressure on roofing materials and slowly breaks them down over time. It can also tear up insulation and cause leak hazards.

Another common type of commercial roof storm damage that typically occurs after an extended period of a storm is drainage failure.

How to Fix Drainage Problems

A stitch in time saves nine, they say in one of the old idioms.

To reduce ponding water:

  • Clean drains and gutters regularly
  • Remove leaves and debris
  • Examine low-lying areas where water pools
  • Schedule inspections before storm season

Proper draining extends the life of a roof and reduces repair costs.

Flying Debris and Impact Damage

Storm winds rarely travel empty-handed. Many branches, construction debris, and nearby items can return with intensity on commercial roofs.

These impacts can cause tears in membranes, fracture skylights, or damage rooftop equipment. Even smaller impacts can strip away protective layers, exposing roof assembly materials.

Because roof hail damage often ranges from debris impacts, commercial roofing problems are more serious.

Debris Damage and What to Do about It

Reducing other existing hazards can minimize storm risks.

Property owners should:

  • Trim nearby trees
  • Secure outdoor equipment and signage
  • Get rid of loose debris around the house
  • Keep up with inspections after storms

Quick cleanup and restoration of the area lessens the risk of further damage.

Preventive Maintenance Works the Best

While not all storm damage can be avoided, much of it does not need to lead to major loss. On a regular basis, seasonal maintenance and inspections can identify weak areas before the storms roll in.

It saves money and reduces the impact of disruption to normal business processes through a proactive approach.

Key Maintenance Practices

Make your commercial roof last longer by:

  • Scheduling routine inspections
  • Addressing minor repairs quickly
  • Maintaining drainage systems
  • Tracking storm impacts during the year

Often, the best defense against expensive roof failures is preparation.
