Hello everyone,
I am currently building my own home with a flat roof. It needs to be greened, which I would like to do myself. Most things are clear to me, but I still need some advice on one point: How should I deal with our external drainage (the spot where a pipe passes through the parapet)? I probably shouldn’t put gravel directly in front of it. But should I simply leave a gap in the gravel, or would it be better to install a barrier made from L-profiles?
I hope I was able to explain my concern clearly enough.
Best regards,
Daniel

In our neighborhood, there are two houses with green pitched roofs. They look great. The slope... well, definitely less than 45° (45 degrees). Sure, no question it’s possible. The question was whether the effort is greater: it is, and a green roof carries more risk of leaks. Everything else is a matter of perspective. Green roofs = environmentally friendly, expensive, and riskier! With pitched roofs – which is why I phrased it carefully earlier – the effort is significantly higher because the roof structure is completely different and more complex.
