Hello everyone,
we have a problem in our new building that ice forms on the ventilation tiles of the sanitary installation at freezing temperatures.
When this then thaws, large ice chunks (approx. 8 cm x 7 cm x 2 cm) slide down the roof and pile up on our parking space with the car. This also happens in the entrance area. Now we are concerned that this could lead to personal injury or property damage.
According to our home builder, this is not a defect and we should have snow guards installed by the local roofer.
What do you think? Is this allowed to happen or is there a standard regulating the execution?
We were never informed about this circumstance.

Thanks in advance for your help!

Your home construction company has shown you the right way. There is no question about that. It is not a defect or your problem if something falls from your roof. The construction company is also not obliged to inform you about all eventualities that come with such a house build.

Ok that's tough that the layperson has to expect life-threatening things. I can still understand snow falling off the roof but something like that .... If this had been discussed during the sampling, we would have had the tiles installed on the garden side or ordered snow guards. Thanks for the quick response.

Yes, it may sound harsh, but unfortunately it is true. A house or household always carries risks, and quite a few people die at home for one reason or another "banal."

Hi,
sorry, but how does ice form there? There is a pressure equalization for the pipes and no overflow. Actually, nothing should form there... No idea if this is a defect, but I would like to understand where the water is coming from.

Apart from that, a snow guard is always a good idea... On our sides without a guard, quite a lot of avalanches come down. You definitely don't want to stand under them.

Best regards,

Andreas

Warm air from inside meets cold outside air, condensate forms ice. Completely normal and not a defect
