Heavy Rain, Heavy Risk: Protect Your Commercial Roof After Extreme Weather

Over the past few days, our area has been hit with an incredible 6–8 inches of rain in a very short time. While that’s great for lawns and landscaping, it’s a real stress test for commercial roofing systems—and one many buildings aren’t designed to pass without some issues.

If you own or manage a commercial property, you may start noticing leaks appearing right about now. This isn’t necessarily because your roof “suddenly went bad,” but rather because commercial roofs aren’t built to handle this much water at once—especially when drainage systems are overwhelmed.

Why Heavy Rain Creates Immediate Risk

Commercial roofs, particularly flat or low-slope designs, rely on a carefully engineered drainage system to shed water quickly. But during record rainfall:

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

• Debris—leaves, branches, and trash—blocks scuppers and downspouts.

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

• Prolonged saturation exposes hidden vulnerabilities that aren’t normally an issue during lighter rains.

Your Best Move Right Now

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:

• Damage to insulation and the roof deck.

• Mold growth inside your building.

• Disrupted operations and potential safety hazards.

• Costly structural repairs down the road.
