Bird nests under the roof - What to do?

Hello everyone,

we have a house from the company Schwörerhaus, which is now about 8 years old.

In the last 4-5 years, we have had more and more problems with bird nests under the roof and under the roof tiles. The roof tiles of the cross brace (see photos) unfortunately do not close on the side, which therefore provides nesting space for birds, which is being used. Do you know if this is normal (so far I have not seen a house with open tiles) and what could be done about it?

Another problem is that the roof under the gutter is also not properly closed (see photo with red arrows). Birds are nesting here as well. Does anyone know if this incomplete closure is necessary or if it is a construction defect? The main problem, unfortunately, is the large amount of bird droppings. I am seriously concerned that the aggressive bird droppings could cause damage under the roof and it is certainly not great for the health of my small children. What could be done here?

The company Schwörerhaus did not help us further.

Thanks for your help and best regards,

Marco

Take any grid and stuff it in there. Or you just check every few days and destroy the nest early. Nest building takes several weeks for many species...

After the nesting season remove the nests and close the entrances, partially bend the grids back, stretch bird protection nets over them. Caution, do not get bird droppings in your eyes, wear protective glasses

Thanks already for the previous answers!

Unfortunately, the house is very tall. The mentioned position is at a height of 8 meters and is only very difficult to access.

Legally, it is problematic to remove nests. Do you have neighbors who do not like you, or a watchman in the area?

Do you know if this is normal (so far I haven’t seen any house with the bricks exposed) and what could be done here?

My neighbors have a 7-year-old Schwörer house, and the bricks look the same there.

or if it might be a construction defect? The main problem is unfortunately the large amount of bird droppings.

I can’t imagine it being a construction defect. A house often offers possibilities for animals. If you then have animals that take possession of it, it is simply nature and/or personal bad luck.
Our neighbors’ sparrows also like to sit on the gutter, while ours prefer the chimney and the flagpole; nests are built in the carport and we let them be. It’s only a rather short time of the year, and bird droppings certainly appear on many paths and terraces.
That’s nature. Ants are annoying too, and I believe they are the ones who really rule the world anyway :)
Swallows are even more annoying…

You can buy or rent scaffolding. In my opinion, you should get something like this anyway for a two-story house. There is always a reason to set it up. Or you can have someone do it. But that costs.
