Hello,

since my parents find re-roofing their house including the garage with Berliner wave tiles (roof tiles are not an option) too expensive (260sqm for 30,000 euros), my father wants to renovate the garage himself because its size is still manageable (about 50sqm).

Currently, Eternit Wave 5 is installed there, directly on the rafters, which have a spacing of about 50cm. Inside the garage, the ceiling consists of drywall panels.

Now we thought: what has lasted for 30 years can’t be so wrong.
So we would simply replace the Eternit panels, again directly on the rafters, and replace the drywall panels inside with Farmacell panels.
In other words, Eternit panel -> rafters -> Farmacell panel.

Roofers would of course do the whole thing more professionally, with counter battens, roof battens, and underlay membrane. Honestly, I don’t know if we could manage that ourselves.
Therefore, we would just replace it 1 to 1.

Alternatively, one could also use trapezoidal sheet metal with fleece, but I don’t know if that is possible without a substructure. Also, it has a different look compared to the residential house.

What do you think? Completely crazy idea? Or a cost-effective renovation option?

take some photos ... sounds like a cold roof ...

Rigips -> Rigips (or GK or plasterboard)
and Fermacell (Fermacell sounds as if the pharmaceutical industry is sniffing into the construction sector)

Upon reading it again, I also noticed it… happens when you type too fast on the phone ;-) I will take photos tomorrow morning.

If I see it correctly, the moisture has quite affected the GK. There is nothing against doing it better. For example, with an underlay membrane.

What is missing from the Eternit panels?

The Eternit panels are now 30 years old and have occasional cracks, through which moisture has entered. Not much and not noticeable, but visible due to the wavy panels. There are no damp spots. Visually, they are also no longer really appealing after all this time. Is a roof and counter battens required for an underlay membrane?
