The Impact of Heavy Rain on Commercial Roofing Systems

Understanding Commercial Roof Vulnerabilities

Commercial roofs, particularly flat or low-slope designs, rely on a carefully engineered drainage system to shed water quickly. However, during record rainfall, several factors come into play that can compromise their integrity:

• Drainage Overload: Drains can’t keep up with the sheer volume of water.

• Debris Blockage: Leaves, branches, and trash can block scuppers and downspouts.

• Ponding Water: Standing water builds up, adding weight and finding weak points in seams or flashing.

• Prolonged Saturation: Extended exposure to water can reveal hidden vulnerabilities that aren’t normally an issue during lighter rains.

  
  

Immediate Actions to Take

After this kind of weather, time is of the essence. Here’s what you should do immediately to protect your property:

✅ Check Your Drains: Make sure they’re clear of leaves, sticks, or any other debris.

✅ Remove Standing Water: Even a small amount can cause major damage if left too long.

✅ Inspect the Roof Surface: Look for signs of membrane stress, lifted seams, or debris buildup.

✅ Document Conditions: Take pictures for your records and insurance purposes.

Why Acting Fast Matters

Ignoring water on your roof can lead to severe consequences, including:

• Damage to Insulation and Roof Deck: Water can seep into the insulation, compromising its effectiveness.

• Mold Growth: Moisture can lead to mold growth inside your building, posing health risks.

• Disrupted Operations: Water damage can disrupt business operations and create safety hazards.

• Costly Structural Repairs: Delaying action can result in expensive repairs down the road.
