ᐅ Flat Roof – What Are Your Experiences and Would You Do It Again?

Hello everyone,

We are in the final stages of negotiations and have decided on a flat roof that will need to be extensively greened.

There isn’t much positive information about flat roofs, although most reports date back to the 1960s and 1970s. I assume this issue has largely been resolved by now.
Still, I’m curious if anyone here has built a flat roof or purchased a house with a flat roof and what your experiences have been. Would you choose it again? Any problems? How do you maintain the roof? And how is maintenance done on a green flat roof?

Thanks a lot!
Best regards

Has no one had any experience?

But I do, quite a lot. However, this probably isn’t the information you were hoping to hear.

Regards, Bauexperte

I'm not an expert, but... An extensive green roof should be inspected once or twice a year. During this, you remove any unwanted plants and ensure that the drainage system is clear and functioning properly. That’s basically it.

Otherwise, I consider flat roofs to be no big issue nowadays if they are installed correctly. Even more so when they are green!

I guess my bosses thought the same.... but unfortunately, at our workplace, the flat roof leaks every 2 years and the contractors have to come...

I’m not an expert either... but my gut feeling tells me that a flat roof will eventually develop leaks sooner or later.

Countless other flat roofs demonstrate that it can also be made watertight.
