Flat Roof Repair: 6 Warning Signs of Damage

As the owner of a property with a flat roof, you don’t want anything to go wrong with your building. However, when you notice something amiss, the last thing you should do is ignore the problems, as they’ll likely turn into bigger issues. And that can lead to roof replacement.

While flat roofs offer several advantages over sloped ones, they are susceptible to leaks and damage that other roofing systems aren’t.

To ensure your roof stays in the best possible condition, it’s best to conduct routine inspections and maintenance. Keeping an eye out for the signs mentioned here will pay off by giving you a chance to respond properly instead of looking for quick fixes.

Signs Your Flat Roof Is In Need of Repair

Read our blog to identify the signs of flat roof damage and make repairs when necessary.

1. Damaged Flashing

 

Flat roofing systems typically have metal edge details that run along their perimeter. This ‘flashing’ is an integral part of a flat roof system as it seals joints and other areas regularly exposed to water. It also helps prevent leaks, ensuring the structural integrity of your property and that the system isn’t compromised.

However, there are certain instances when the metal detail may bend, and, in others, you may notice rusting or other types of damage.

If the flashing isn’t sealed properly, it will allow water to seep into other parts of the roof, resulting in its structural integrity being compromised. Left unaddressed, you may need to replace your flat roof sooner than anticipated. But taking care of the issue as it comes to light, you will prevent water damage and protect your flat roof.

 

2. Cracked Tar

As time passes, the tar used on your flat roofing system may shrink and crack. This will eventually lead to the expansion and protrusion of roof joints. Furthermore, changing weather that exposes your flat roof to freezing and thawing may lead to leaks.

If you notice these signs, your flat roof is most likely in need of immediate repairs, especially when visible cracks appear on the tar. In such instances, it’s a good idea to contact a flat roof repair company near you. They will have the expertise and tools required to seal the cracks and minimize damage.

 

3. Cracking, Bubbling, or Blistering

Cracking, bubbling, and blistering, all are signs of the moisture trapped beneath the surface of your flat roof. In most instances, the sun heats the moisture; this results in the membrane expanding and cracking, which allows water to seep into the structure and damage the building. This is generally a recurring cycle that will jeopardize your flat roof’s integrity over time.

 

4. Pooling Water

One of the most common signs that your flat roof requires repair is standing or pooling water. A flat roof actually slopes slightly to allow water to drain properly. This ensures the roof doesn’t accumulate standing water and collapse, as the puddles allow the moisture to enter the inner layers.

If you notice puddles accumulating on your flat roof or that it has begun sagging in certain areas, it’s time to call your contractor. They will be able to determine exactly what is wrong and take the necessary steps to prevent the issue from getting worse.

 

5. Mould and Mildew

Over time, you may notice mould and mildew accumulating on your flat roof in the form of stains, discoloured areas, or black spots.

Moisture is one of the leading causes of this, and it can easily make its way into your interiors and cause significant damage. Along with making the building appear damaged, it may compromise the indoor air quality, leading to a wide range of respiratory issues. This is why the issue must be addressed as soon it’s noticed.

 

6. Interior Water Stains

Some roofing system issues can be detected inside the building. In such instances, you will notice water stains on the walls or ceiling of the upper floors. This means it’s time to investigate the issue and have the roof repaired to prevent further damage.

When it comes to flat roofing systems, small problems may lead to bigger issues that, when left unaddressed, may harm its structural integrity. It’s best to detect these issues when they are still minor to prevent them from spiralling into more expensive and time-consuming repairs, which may also lead to a replacement.
