For both residences and commercial property, flat roofs are often the most popular and affordable. However, flat roofs are more prone to issues than sloped roofs, making it crucial to detect roof repair problems early. Ignoring these warning signs can result in costly damage and even safety hazards. Here are 5 important signs you shouldn’t ignore, and take action before the problem worsens, namely call flat roof repair services immediately.

1. Collection of Water on Your Flat Roof

The drainage of a flat roof should function properly to avoid pooling water. However, one of the most frequent indications of flat roof damage is pooling water. Standing water can cause severe structural problems over time. That water will eventually soak into the roofing materials, weakening the entire area.

What to Do: Check your roof for pooling during heavy rain or storms. If water is standing, immediate emergency roof repair is necessary before it gets worse.

Causes of Pooling Water:

  • Poor drainage installation
  • Sagging areas on the roof
  • Blocked drainpipes by rubbish

2. Cracks and Splits in Your Roof Membrane

Flat roofs often use membranes like EPDM or TPO, which can wear out and crack due to extreme weather conditions. It is one of the main roof repair signs that should not be ignored.  These cracks allow water to get in, which can lead to significant structural damage. These cracks are often small and hard to spot unless the roof is regularly inspected.

Solution for Cracks: Look for any cracks, and consult with a professional contractor to install patches or replace the membrane as needed.

3. Blistering or Bubbling of the Roof Surface

Blisters or bubbles on the roof indicate trapped air or moisture between layers of roofing materials, often caused by high temperatures or poor installation. Over time, these blisters can grow larger, leading to punctures and roof weakening. Spotting blistering early can save you from expensive flat roof repair costs in the future.

Solution for Blisters: Check for raised or fluid-filled sections, and call a roofer for an inspection if needed.

4. Stains or Wet Spots Inside the Building

Water stains on your building’s interior indicate that the roof is already leaking. If untreated, leaks can harm both the roof and the structure inside, fostering mold, weakening ceilings, and creating electrical issues.

Common Water Stain Locations:

  • Ceiling corners
  • Around skylights
  • Near windows or doors

5. Roof Sagging or Drooping

A flat roof should be level, so sagging is a significant cause for concern. This could be due to poor construction, pooling water, or excess weight from snow or debris. Sagging suggests a weakened roof structure and poses safety hazards.

First Steps: Remove debris or excess weight, and call a roofer for an inspection to recommend repairs or re-roofing.

When to Call a Professional

Recognizing these signs of roof repair early can save you from costly repairs and safety hazards. Pooling water, cracks, and other issues are early indicators, and a qualified roofer can assess and recommend the necessary repair steps.
