Roof tiles: Clay or concrete - Does clay tile really last that much longer?

Hello,

things are getting serious here, the first small step towards renovation is about to take place and we are currently collecting offers from roofers.

I keep coming across the question of clay or concrete. We are currently getting offers for clay because originally clay was planned, but personally it bothers me (as always) that, in my opinion, not enough consideration has been given to the alternative.

Appearance does not matter here. Only what makes the most sense so that in the end it is the cheapest. And possibly what kind of "effort" the roof will cause in the long run should also be considered.

I hear different things. Some say clay and concrete are now equally durable. That concrete nowadays is just as good. Then elsewhere it is said that clay lasts easily 10-20 years longer. Then, clay is a few thousand € more expensive (but it lasts 10-20 years longer after all).

Concrete is said to look less nice more quickly because moss or similar can form faster. As long as it is only a visual limitation, we don't care. It is only interesting for us if we would have to regularly remove such things.

I am currently trying to absorb what the roofers are trying to push on me and what I can read on the internet. Unfortunately, the more I hear and read, the less I understand.

I would therefore be very grateful for your experiences and opinions.

And I would be even more grateful if no one would tear me apart or be unfriendly now because I don’t know enough or should have informed myself beforehand, etc. It is very complicated here ([Erbengemeinschaft, schwerkranke darunter, Diskussionen, usw.]). A renovation was actually not planned anytime soon.

I would very much appreciate a nice, factual, and helpful exchange and would be very grateful to you for that.

Best regards

Engobed clay roof tiles.

Costs a bit more, but looks clearly better for much longer. Drive to new residential areas that are 5-10 years old.

Concrete quickly looks dull.
Later, sand trickles down into the gutter.
Price difference for me 2800 euros for (280 sqm roof area).

Whoever saves there probably also chooses double-glazed windows.

What does "Sanierung" mean? - How old is the house and why should/must the roof be replaced?

The house is from 1959, the roof is just as old. No insulation, only clay tiles on rafters, with heavy rain moisture already comes through in several places.

Renovation means roof, exterior insulation, ceiling insulation in the basement, new windows (all no longer 100% sealed), new electrical wiring, new water pipes (lead pipes) and cast iron radiators must be at least cleaned from the inside or replaced by other radiators. In addition, small things should be done but are not absolutely necessary (e.g. completely digging up the garden because it can no longer be walked on barefoot, etc.)

In the energy consultation, which we arranged ourselves quickly a few years ago (at that time we had just become part of the joint inheritance community and no one really wanted to deal with it), 255 kWh/m2 came out. :-/

It is a two-family house. Upstairs us (so it also rains inside our part), downstairs the main owner (over 90). The last co-owner lives elsewhere and, according to his own statement, had no interest in the house a few years ago.

I hope this at least provides a small overview. To quote the energy consultant, the foundations are solid, so it is more profitable to renovate than to tear down and rebuild. But that is the only thing, "everything else" needs to be done.

It is not a small project. We are already working on it at every corner. The roof is only currently in focus because 1. it leaks and 2. it is now the first topic to discuss whether the third owner will still cooperate at all or sell his share. Unfortunately, he is now under pressure because we have seriously threatened to move out, which is not in his interest.

below the main owner (over 90)

That already sounds a bit like remaindermen on the horizon. Does anyone over 90 still have an interest in the topic of renovation?

The over 90s owner is not the problem, but the other co-owner :-( It may sound absurd (believe me, we can hardly believe it ourselves) but unfortunately, it is the case.
