Flat Roof Repair: 6 Warning Signs of Damage

So, you have recently installed a flat roof for your commercial property.

Good choice! Since they are an ideal cost-effective option. However, like any other roofing system, they are still vulnerable to damage.

As the new owner of a flat roof, you obviously don’t want anything to go wrong with your building. This means you need to keep a close eye on your roof to ensure it stays in the best conditions for as long as possible.

Here is a brief list of the main warning signs of damage you need to watch out for in order to act quickly and acquire the right flat roof repair service you need to help extend your roof´s life

Water Pooling

Pooling water might seem like a minor problem, but it can cause big unresolved issues.

It can end up causing leaks, weakening walls, and making the roof uneven.

So if you notice puddles accumulating on your flat roof, it’s time to call your roofing contractor.

Wall Bubbling

Another sign of damage is the one that takes the form of bubbles.

This happens due to the moisture trapped inside your roof´s structure and the fluctuation in the temperature which swell the roof material.

Be sure to watch out for the weather. If you feel any deterioration on the ceiling surface, it’s best to call a reliable roofing service provider for further inspection.


Usually, flat roofs have a thin sheet of metal (flashing) to prevent water from seeping through your roof. Sadly, it can pull away from the roof’s edges as time passes.

So if the flashing is not sealed correctly, it will cause the water to seep into other parts of the roof, affecting its structural integrity.

It is not ideal to leave this problem for later since it could worsen and lead to more severe problems, and in the worst-case scenario, you will no longer need a roof repair but a roof replacement.


Sometimes, you may notice stains or discolored areas in your roof, which could form over time due to mold.

This happens mainly because of moisture, and it can easily make its way into the interior of your building and cause significant damage and affect the quality of the air inside.

You must address the issue as soon as you notice it.

Small Cracks

This is the most obvious sign you can notice, but you will be surprised how many people ignore it.

Sure, the cracks tend to be small, but they can significantly damage the roof structure.

A flat roof repair company can quickly provide roofing services to identify such small cracks, which can be internal or external.

Top Coat Damage

The Topcoat is a solution that covers the roof to give a pleasant cosmetic finish and a watertight seal.

However, this seal can still suffer damage, which you can notice when you are outside and hear a constant fluttering sound.

Don’t let your flat roof fail because of something as simple as top coat damage.

Although these warning signs of damage may not seem like a big deal at first, they can still seriously affect your budget to a great extent.

To avoid this, it is best to identify the flat roof problems right at the beginning and solve them just as quickly, but you need to have the right roofing contractor for the job.
