Hello everyone, I’d like to hear your opinions on the following issue:
I’m asking on behalf of a friend:
They are currently renovating their house, and the facade company has just applied the insulation. The same company was supposed to do roof renovation as well (cleaning and sealing). The roof is about 50 to 60 years old, and some of the tiles are already broken in several places, with moss and lichens growing on them. The battens underneath seem to be in good condition as far as we can tell. There is no underlay membrane, so wind-driven rain can get through and end up on the fiber cement boards or within the insulation between the rafters. However, it dries out again there, and there are currently no mold issues—also no vapor barrier or similar. The roof space is mostly used for storage. Everything is fairly open except at the dormers and the sloped ceilings on the upper floor. Only one dormer had problems—there we replaced the beams because they had rotted. A gas boiler chimney was apparently incorrectly installed there; it has now been replaced, and everything looks clean again.
Roof pitch is 48 degrees, slightly less—about 20 to 25 degrees—at the dormers.
Roof covering: red tiles.
Now the company is recommending reroofing because the tiles have weathered so much. Cost would be 10,000 to 15,000 euros. The money just isn’t available at the moment, no chance.
Now there is a disagreement:
One party wants to have the roof sealed (around 4,000 euros) and get a 10-year warranty on that. During those 10 years, they want to save money for a new roof.
The other party claims the warranty only covers the paint and doesn’t significantly extend the roof’s lifespan. This party would rather save the money and wait 5 years to have enough for a full reroof when it starts leaking.
What do you think?

The only serious issue is when there is a leak that goes unnoticed and something remains damp for a long time, like what happened with your house.That was problematic because the water ran behind the bathroom tiles and caused the beams to rot. We only discovered it when we demolished the bathroom :-(

We had our now 60-year-old roof inspected by two roofing contractors. Of course, both wanted to replace the roof. One eventually admitted that technically it was not necessary. The connection points should be watertight (chimney, dormers), the tiles free of moss, and everything solid. That’s exactly right – there are two proper professional approaches: A. Replace damaged parts and ensure watertightness. Or B. Complete reroofing. For the homeowner, both are the same, but for the professional, option B is the bigger job.

The same company was supposed to carry out roof renovation (cleaning + sealing). That would be the unprofessional option C: washing, brushing, hairspray – coincidentally priced just under the limit the homeowner can barely negotiate from their bank. There are few fraudsters whose resumes do not include a stint as a roof renovator.
