Top 3 Roofing Issues That Happen in Summer—and How to Prevent Them

Summer means sunshine, longer days… and heat-related roofing problems that can sneak up on you if you’re not looking.

At C&R Roofing, we see certain issues peak during July and August—especially on flat and low-slope commercial roofs. Here are the top 3 we watch out for (and how we help clients prevent them):

1. Roof Blisters & Bubbles

These are pockets of air or moisture trapped under your roof membrane, and they’re made worse by heat. When the sun beats down on your roof, those pockets expand, sometimes causing visible bubbling or surface damage.

🔧 Prevention:

• Regular inspections

• Addressing even small punctures quickly

• Proper venting and moisture control during installation

2. Cracked or Lifting Flashing

Flashing protects roof edges, vents, skylights, and HVAC units. In summer, metal flashing expands and contracts daily due to heat, eventually causing it to pull away from the surface.

⚠️ Why it’s dangerous:

• Exposes seams and edges to water

• Can lead to leaks even in dry weather (via condensation)

🔧 Prevention:

• Seasonal flashings check-up

• High-quality materials that resist UV fatigue

3. Ponding Water from Summer Storms

A common myth is that flat roofs should hold water. In reality, standing water for more than 48 hours is a red flag. It can weaken your roof membrane and lead to mold, algae growth, or structural damage.

💧 Prevention:

• Clear drains and scuppers every season

• Add tapered insulation to improve slope

• Schedule routine maintenance in late summer to prep for fall

☀️ Stay One Step Ahead of the Heat

Don’t wait for damage to show up in your ceiling tiles. With a quick inspection and summer prep, you can protect your building and your bottom line.
