Hello,
On our attached structures (garage), we have standing water for an extended period (24-36 hours) after rain showers. I estimate about 5 cm (2 inches) and plan to inspect the roof soon.
The developer says this is completely acceptable for a flat roof or even good because of the waterproofing.
I’m having a hard time with that 😳

I remember your builder as a reliable and competent partner – are you sure there is actually 5 cm (2 inches) of standing water? Our eyes can sometimes deceive us.
If this is indeed the case, it could mean that the required slope of 2% on the flat roof was not properly implemented ... assuming, of course, that the drains are not the cause, for example, clogged with leaves.
Best regards, Bauexperte

for me, it means going up onto the roof with a spirit level. I hope it’s not 5cm (2 inches). In the meantime, we had a good conversation. I will keep you updated.

The roof also has a slight slope, but only up to the corner where the gutter is installed. At that point, the roof is level again. Therefore, the remaining 1.5 cm (0.6 inches) of water can never drain off.
It’s somewhat comparable to a shower tray (I hope you understand what I mean).
Now, of course, the question is whether this is harmful or not.....

toxicmolotof26 Feb 2015 08:15How large is the puddle? I believe it’s probably harmless, BUT I’m not a roofer.
We also have small areas, roughly 20cm by 80cm (8 inches by 31 inches), where about 1cm (0.4 inches) of water tends to collect.

Water is standing between 0.7–1 cm (0.3–0.4 inches)....
The roof insulation makes the situation a bit misleading.
Now the question is whether to take action or not. I have always learned that water finds its way... but it could also be that everything above is sealed.
