How should the house dry / roof battens and bad weather

Hello dear forum,

the shell is up.
Only the roof tiles are still missing. The battens have been exposed to bad weather for days.
Do these dry out again or should we possibly expect damage?
And do the battens have to be dry before the tiles can be laid?

Also, we won't get a key to our house until handover.
We are allowed to come by during the day as long as a company is on site,
but otherwise we have no access – so we cannot ventilate now or later.
How does the construction company keep the house dry then?
At the moment, all windows are tilted open day and night. Is that enough?

I would appreciate answers.... Regards

In general, wet wood can be dried again as long as it is not standing in water. A little rain often doesn’t do any harm. However, it should be in the interest of your general contractor to keep everything as dry as possible. That is why such things are usually covered with foil until the roof is covered.
Moreover, it also depends on what is planned for the roof? If it remains a cold roof, it will usually dry later through continuous ventilation... if it is going to be a converted roof, everything must be dry beforehand.
That you are not allowed into the house is the contractor’s legal right... The house belongs to him until handover has taken place. For such construction projects, I would definitely involve a building surveyor for construction supervision and acceptance. Otherwise, you might end up buying a pig in a poke with wallpaper on it. If screed is still being poured, a lot of water will come into the house... then either heating like crazy or using expensive construction dryers will be done... in any case, in theory, the GC is obliged to hand over a dry house to you; how he does it is his problem.

Hello there, okay... that calms me down a bit for now. Thank you for the quick and detailed response!

Regards

WHY does that reassure you? I don't know how the weather is where you are, and how long it will stay open. I was speaking completely generally. You should simply have someone before the acceptance who can tell you whether it is too damp or not. You cannot judge that as a layperson.

I meant, it reassures me that the thing with the keys does not seem to be so uncommon after all.

The roof is now complete.

Thanks for your answers. Regards

It is now unfortunately too late to guarantee with the extra access right.

I will probably have to consult the expert.
