Reasons Why Flat Roofs Leak | Preventing Roof Leaks

Any buildings that have been built in the latter decades of the 20th century have flat roofs since that was popular around the time. If you want to know why flat roofs leak, you have come to the right place. Let’s get down to it!

1. Age

Depending on the roofing materials you have, the roof may have reached its maximum lifespan. Newer materials have better longevity, so you should get the roof inspected properly. If it has reached the end of its life, you should get it replaced with newer technologies and materials.

2. Solar Gain and Temperature Changes

When asphalt ages, it can become brittle and hardened. Any temperature changes and thermal movement can lead to cracks and splits in the surface that allows more water penetration. This can be one of the reasons why flat roofs leak.

3. Movement in the Roof’s Structure

Building materials can contract and expand because of the heat. Traditional materials may not have a proper membrane system that can accommodate the movement of materials. Modern flat roof materials are designed while taking into account how the heat will affect the roof.

4. Blisters

If your waterproofing has large blisters, it is evidence of moisture and air trapped in the surface. When water enters the structure of the roof, it can impact the humidity and internal temperature of the roof. When the internal temperature increases, it turns the water into vapor that blisters the surface.

5. Delamination

If the membrane layers get condensation, delamination can occur. Delamination is when the membrane layers start to separate, meaning that there isn’t any connection between the layers. This can increase the risk of getting water into the layers, damaging the structure.

6. Poor Detailing and Design

When you are installing a new roof, you need to make sure that you get professionals that know how to have a proper design. For example, if you don’t have proper falls, it can lead to water pooling on the roof and increasing the risk of structural damage. You need to make sure that roofing specialists are planning out the design for the flat roof because it still needs to have adequate planning to ensure it doesn’t develop leaks.

7. Bad Workmanship

One thing that homeowners should always remember is that professional roof installation requires a high level of skill and experience. If it is not installed in the correct manner, it will end up failing and costing you thousands of dollars. This is why it is always important to go for accredited and qualified contractors that can handle your roofing project with competency and efficiency. You should also make sure that your contractors don’t cut corners when it comes to roof installation, and neither do you. Getting the best materials for your home and hiring professional contractors like Utah Roofing will ensure that your roof has a long, long lifespan.

We hope now you know why flat roofs leak and hope that you take measures to stop these leaks from happening in the future.
