Flat roofs are a popular choice for commercial buildings in the St. Louis area due to their affordability, ease of installation, and accessibility. But with great design comes great responsibility—especially during the hot and stormy summer months.

If you manage a commercial property, taking proactive steps in June and beyond can save you from costly repairs down the road. Here’s what you need to know to keep your flat roof performing at its best this summer.

1. Clear Debris from the Roof Surface

Leaves, branches, and other debris can accumulate quickly on flat roofs. Not only do they create tripping hazards for maintenance crews, but they can also block drains and cause water pooling—leading to leaks or even structural damage.

Pro Tip: Schedule a roof cleaning at least once a season, especially after a storm.

2. Inspect and Clean All Drains and Scuppers

Water is your roof’s biggest enemy. Flat roofs are especially vulnerable to ponding water if drainage systems are clogged. Make sure all internal drains, scuppers, and downspouts are clear and functional.

Warning Signs to Watch: Standing water, slow-draining scuppers, and water stains near drainage points.

3. Check for Cracks, Blisters, and Membrane Damage

St. Louis summers bring extreme heat that can cause roofing materials to expand and contract, leading to cracks, bubbles, or open seams—especially in older TPO, EPDM, or built-up roofing systems.

What to Look For:

• Bubbles or blisters on the surface
• Open seams at flashing or edges
• Cracked sealant or caulking

If you notice any of these issues, it’s time to call in a professional for a more thorough assessment.

4. Examine Roof Penetrations and Flashing

HVAC units, vents, and other rooftop equipment are common sources of leaks on flat roofs. Check the flashing and seals around all penetrations to make sure they’re watertight and properly installed.

Summer Tip: The heat can cause flashing materials to dry out or shift, so summer inspections are key.
