Obvious Signs of Damage in Flat Roofs

Updated: Jun 27


Water Pooling on the flat roofs

Any flat roof in Cambridge, Ontario has to be able to stand up to the range of harsh weather the region has to offer. From scorching heat to bone-cracking cold, Cambridge can see temperature variances of more than 70°C over the course of a year, from -30°C to nearly 40°C in the summer.


Over time, a flat roof can wear out and suffer damage. If you don’t repair the damage immediately, it can lead to much greater problems. This blog outlines signs you should watch out for that indicate damage to your flat roof.


Signs You Should Not Ignore


Water Pooling

One of the biggest problems any flat roof repair company comes across is the pooling of water on the surface after rain or from melting snow. While flat roofs are designed to withstand some pooling, persistent water pools can cause wear over time if they aren’t draining properly.

 

Water continually pooling in the same spots means your low slope flat roof is not as flat as it may seem. Over time, your building may shift or settle. That’s perfectly natural. However, it can lead to water gathering in the same spot over and over, which puts stress on your roof, erodes roofing materials and puts it at risk for more damage. Further, water allows for the growth of algae, moss and vegetation which stains and damages roof membranes.


Flashing Problems

The flashing is a thin sheet of material that’s meant to prevent water from seeping through your roof. It’s not always easy to see the full extent of flashing problems, which can make them easier to ignore.

 

This is a mistake.

 

If these problems are left unresolved, it can lead to catastrophic damage to your flat roof. Flashing can pull away from the edges of your roof as time passes. Asphalt flat roofs will expand and contract with the heat and moisture changes of the Cambridge weather.

 

Topcoat Damage

Topcoat is the membrane covering your flat roof to give it a nicer cosmetic finish, plus provides an important watertight seal.

 

The most obvious sign of topcoat damage that you should keep an eye out for is a fluttering noise. When you’re outside your building, and sometimes even inside, listen for a constant fluttering noise. This is especially noticeable during high winds and can mean your topcoat has been damaged and is coming away from the rest of the roof.

 

This leads to gradual damage, leaks and exposure of the roofing layers under the top membrane to the elements.


Leaks and Moisture Problems

Cracks and leaks are the most obvious sign that your flat roof is in need of fixing or replacing.

 

As with any other roof, flat roofs can be vulnerable to unwanted moisture. Moisture from long-term pooling can make cracks appear and cause them to become worse over time.

 

The biggest issues that come with excess moisture are mould and structural damage. No one wants to have to deal with either issue as they can mean big expenses.
