Periodic flat roof maintenance: what should you be aware of?


Since a damaged roof can cause major problems, it is a good idea to inspect your flat roof on a regular basis. First and foremost, make sure you climb up onto the roof safely. But apart from safety, what is also important during periodic flat roof maintenance? We would like to give you a brief explanation.


Inspecting your roof every year is certainly not an unnecessary luxury. A poorly maintained roof can fall into disrepair more quickly, especially in rainfall during the winter, or summer downpours. Seeping moisture due to heavy rain, hail or snow is the biggest culprit, and can cause considerable damage. But moss and algae also affect the quality of your roof.

It is therefore best to plan an inspection before the winter, after the leaves have fallen, and then after the winter, to check for any frost damage. This gives you enough time to carry out any repairs before the weather turns worse again in the autumn.

For a flat roof, checking the roof twice a year is sufficient. You can choose to climb onto the roof yourself to carry out a check, but this is always risky. Do you want peace of mind about the state of your roof, while also keeping both feet firmly on the ground? Then it’s a good idea to have an inspection carried out by a professional roofer.


If you decide to climb up onto the roof yourself, make sure you always put your safety first! Make sure that the ladder is completely stable, and use an anti-slip mat, so the ladder has even more stability. There are also a number of other things to watch out for. Please note: the following attention points are a good place to start for the roof inspection, but they are not a comprehensive checklist. A roofer can always give professional advice.

1. The state of the roof covering

First of all, check the state of the roof covering, regardless of the type of material. Any damage or loose elements should ring an alarm bell straightaway. Also thoroughly check any roof details, such as the sealing around a chimney, roof uprights or roof windows. These are often weak links on a flat roof, where leaks can occur more easily.

2. Load-bearing elements

Also check the load-bearing elements of the roof construction. Check that the wood has not been affected by insects or water seepage.

3. Gutters

Regularly remove all leaves, branches and detritus from the gutters. These can prevent water drainage, and can cause serious damage to your roof. Also check that the gutters are not damaged, and have a feel to see if they are still firmly attached.

4. Moss on roof

Moss, lichen, algae and possible plant growth should be removed immediately. Please note: never use bleach or chlorine to remove moss, and don’t just pull out rooted plants. That might result in leaks occurring. It’s best to leave these plants where they are, and ask a professional for help. Using a high-pressure cleaner can also damage the roof covering. They increase the risk of water seepage. To maintain green roofs, you should ideally contact the installer of your green roof.
