Is roof renovation for an old roof sensible?

The only problem is when it's leaking and you don't notice it and something stays permanently damp, like with your house once.

That was problematic because it ran down behind the bathroom tiles and the beams rotted. We only noticed when we knocked out the bathroom :-(

We also had our now 60-year-old roof inspected by two roofers. Of course, both wanted to reroof it. One eventually admitted that, technically, it was not necessary. The connection points should be sealed (chimney, dormers), the tiles not moss-covered, and everything secure.

That's exactly right – there are two professional ways: A. Replacement of damaged parts, ensuring tightness. Or B. Complete reroofing. For the homeowner, both are the same; for the professional, B. is the bigger job.

The same company was also supposed to carry out roof refurbishment (cleaning + sealing).

That would then be the unprofessional way C.: washing, brushing, hairspray – coincidentally priced just below the limit that the homeowner can still squeeze out of their savings bank. There are only a few fraudsters whose life stories do not include the chapter of roof refurbishers.
