Flat roofs are a popular choice for modern homes and commercial buildings, but they come with their own set of challenges — especially when it comes to leaks. Unlike pitched roofs, water doesn’t run off as easily, which can lead to pooling, deterioration, and eventually, leaks.
In this article, we’ll walk through common causes of flat roof leaks, quick DIY fixes, and when it’s time to call in a professional.
Common Issues That Lead to Flat Roof Leaks
Flat roofs are prone to specific types of wear and tear. Some of the most common problems include:
- Ponding water: Water that doesn’t drain properly adds extra weight and slowly damages roofing materials.
- Cracked membrane or blistering: Over time, exposure to sun and temperature changes can lead to cracks or bubbles.
- Faulty flashing or seams: Poorly installed or aging flashings are often a leak’s origin point.
- Clogged drains and gutters: These prevent proper drainage, leading to water buildup and eventual seepage.
DIY Fixes for Minor Flat Roof Leaks
If the leak is small and you’re comfortable working on your roof, here are some steps you can take:
1. Locate the Source
Carefully inspect your roof for soft spots, bubbling, or visible cracks. Keep in mind that water can travel under the surface before it becomes visible indoors.
2. Clean the Area
Remove dirt, debris, and moisture before making any repair.
3. Use Roofing Cement or Sealant
Apply a roof patch or roofing cement to seal cracks and holes. For small punctures, roofing tape can work temporarily.
4. Install a Temporary Patch
For larger cracks or tears, a roofing fabric patch with bitumen can buy you some time before calling a pro.
Important: These solutions are temporary. They may slow the damage, but rarely solve the root issue completely.
When to Call a Professional
Some situations call for expert assessment:
- The damage is extensive or widespread
- Water is pooling in multiple areas
- You're unsure of the leak’s source
- Temporary fixes didn’t work
- There’s structural damage or insulation is wet
