The Anatomy Of A Commercial Flat Roof: Damage Points, Maintenance & Reinforcements

Commercial flat roofs are unique in that they experience a great deal of traffic and weather exposure. It is essential to be aware of the different damage points on your rooftop and maintain them properly. Raleigh Roofers will discuss the anatomy of a commercial flat roof and what you need to know to keep it in good condition!

Anatomy of Flat Roofs

The first thing to understand about commercial flat roofs is that they are not entirely flat. There is a slight slope to them, allowing water and debris to run off. However, over time, this slope can become less pronounced and cause problems with drainage. If you observe water pooling on your roof, you must immediately have it inspected by a professional.

Potential Damage Point on Commercial Flat Roofs


The most common damage point on commercial flat roofs is the seam. These are the areas where two pieces of material come together, such as at the edge of a roof or where two different types of material meet. They may have been damaged due to improper installation, age, or weather exposure. If there are any fissures in your roof seams, repair them immediately to prevent water from leaking in.


Another common damage point on commercial flat roofs is the drains. Drains can become clogged with debris, leaves, and dirt, which can cause water to back up and pool on the top. If your gutters are slowing down or are entirely clogged, getting them clean out as soon as possible is essential.

Solutions to Flat Roof Damages

Regular maintenance is the best remedy to prevent your commercial flat roof damage. It should include an annual inspection by a professional roofer to check for any signs of wear or tear. It is also vital to clean gutters and drains regularly to prevent clogging.

If your commercial flat roof does sustain damage, it is essential to have it repaired as soon as possible. More minor repairs can often be made on your own, but more extensive damage will require the help of a professional roofer.

Here are a few solutions to reinforce your commercial flat roof and prevent future damage.

Metal Flashing

First, consider installing metal flashing around drains and gutters. It will help to prevent leaves and debris from clogging them.


Second, you may want to install a thicker insulation layer to help protect against extreme temperatures.


Lastly, consider adding a layer of protection such as a tarp or membrane over the top of your roof.

Ending Note

A commercial flat roof experiences considerable traffic and weather exposure. Damage can occur at various points on the top, so it’s essential to be aware of these areas and take steps to prevent damage. Additionally, regular maintenance is necessary to keep your roof in good condition.
