Common Flat Roof Issues

Repairing a flat roof can be a daunting task, but understanding the common issues that arise can make the job much easier. Flat roofs, while practical and space-efficient, come with their own set of problems. Recognizing these issues early can save you time, money, and a lot of headaches. Here, we will discuss two of the most common problems: ponding water and cracks and blisters.

Ponding Water

Ponding water is a frequent issue on flat roofs. Unlike sloped roofs, flat roofs do not naturally drain water. This can lead to water pooling in certain areas. Over time, this standing water can cause significant damage.

Why is Ponding Water a Problem?

Structural Damage: Prolonged water exposure can weaken the roof structure.
Leaks: Water can seep through small cracks, leading to leaks inside the building.
Mold Growth: Standing water can promote mold and mildew growth, posing health risks.

Inspect the Roof: Check for any visible dips or low areas where water collects.
Improve Drainage: Add extra drains or improve the existing drainage system.
Add Tapered Insulation: Install tapered insulation to direct water towards drains.
Regular Maintenance: Ensure drains are clear of debris to prevent water buildup.

Cracks And Blisters

Cracks and blisters are other common problems on flat roofs. These issues can compromise the roof’s integrity and lead to leaks and further damage.

Why Do Cracks and Blisters Occur?

Sun Exposure: UV rays can cause the roofing material to deteriorate and crack.
Temperature Fluctuations: Extreme temperatures can lead to expansion and contraction, causing blisters.
Poor Installation: Incorrect installation can result in weak spots prone to cracking and blistering.

Identify the Problem Areas: Inspect the roof for any visible cracks or blisters.
Clean the Surface: Remove any debris or dirt around the damaged area.
Cut Out Blisters: Carefully cut away the blistered area without damaging the underlying layers.
Apply Roofing Cement: Use a high-quality roofing cement to seal the cracks and fill the cut-out blisters.
Add a Patch: Place a patch over the repaired area to reinforce the fix.
Regular Inspections: Schedule regular inspections to catch and repair new cracks or blisters early.
