ᐅ Inlet too close to the parapet – designed by the architect

Hello everyone,

We noticed that the inlet/outlet of our flat roof is about 12 cm (5 inches) away from the parapet. According to flat roof guidelines, this distance should be at least 30 cm (12 inches). The roofer pointed this out, but the architect is downplaying it.

What should we do? I’m inclined to inform the architect in writing that the guideline must be followed and that they would be liable for any damages. What happens if the drain only becomes faulty after 10 years due to this planning error?

What do you think?

Thanks for any advice and best regards,
Alex

Can't it simply be corrected during construction?

The roof is finished, and the pipes run through the exterior wall. Because of this, making corrections is no longer really feasible. At most, the drain could be drilled in a completely different location, which would, of course, be quite an extensive effort. It is also the only drain on the entire roof (besides the emergency drain, of course), and the tapered insulation (which was just approved by the architect) directs the water flow precisely to this point.

Did the roofer inform you this late, or are you just responding this late?

The topic only came up during the roofer’s inspection; I wasn’t aware of it and assumed the architect had some experience with it.... The architect has now also given the roofer the "go-ahead" by email ....
