Flat Roof Leaks: Causes, Fixes & Why You Need a Pro

Flat roofs are a popular choice for both residential and commercial properties across Mexborough, South Yorkshire. Their modern appearance and practical use of space make them attractive, but they can be prone to leaking if not properly maintained. At ATY Roofing Mexborough, we regularly assist homeowners and business owners dealing with flat roof leaks, offering fast, effective, and long-lasting solutions.

Common Causes of Flat Roof Leaks

Understanding what causes a flat roof to leak is the first step in preventing or resolving the issue. Some of the most frequent causes include:

• Ponding water – Flat roofs often lack sufficient drainage, allowing water to collect and eventually find its way through cracks or seams.
  
• Damaged membrane – Over time, weathering, UV exposure, and foot traffic can damage the waterproof membrane, leading to leaks.
  
• Cracks or splits – Temperature changes can cause materials to expand and contract, resulting in cracks or splits in the surface.
  
• Poor installation – Substandard workmanship or use of cheap materials increases the likelihood of early failure.
  
• Blocked outlets or gutters – Debris build-up can prevent water from draining properly, creating pressure on weak points in the roof.
  

How to Spot a Flat Roof Leak Early

Catching a leak early can save you significant repair costs. Keep an eye out for:

• Damp patches on ceilings or walls
  
• Mould or mildew growth indoors
  
• Bubbling or blistering on the roof surface
  
• A musty smell in rooms below the roof
  
• Water pooling on the roof for extended periods
  

If you notice any of these signs, it’s best to have your roof inspected by a professional without delay.

How Flat Roof Leaks Are Repaired

At ATY Roofing Mexborough, we take a thorough and methodical approach to fixing flat roof leaks for properties across Mexborough, South Yorkshire. Here’s how the repair process typically works:

Step 1: Full Roof Inspection

We begin with a detailed survey to identify the leak source, assess the extent of the damage, and determine whether it’s isolated or more widespread.

Step 2: Determine the Best Repair Option

Depending on the roof’s condition, we may recommend one of the following:

• Patch repair – For small cracks or localised damage
  
• Overlay system – Applying a new waterproof layer over the existing roof
  
• Full replacement – When the roof is extensively damaged or at the end of its lifespan
  

Step 3: Professional Repair Work

All repairs are carried out using high-grade materials and proven techniques. We ensure proper sealing of joints, flashing, and outlets to prevent recurrence.

Step 4: Preventative Measures

After the repair, we may advise:

• Regular maintenance checks
  
• Gutter and drainage cleaning
  
• Roof coating to protect from UV and weather damage
