Crumbs ... already wincing at the thought of that bill. We also bank with UBS but used the Kantonalbank (Zürich in our case) for our mortgages. We found them much more flexible and have also made some preliminary enquiries on borrowing money for house renovation.
Did you look at roof renovation rather than replacement?
I don't know if this is a possibility in Switzerland, in other countries this is a much cheaper option, especially if you are older and do not want to build a solution that is good for 80 years.
Yes, getting several estimates with different 'levels' of renovation. Scafolding alone is huge! And swapping copper for zinc makes huge difference. But still talking about large sum! 75-100K.
Are you on a fixed term or a variable rate mortgage with UBS? If it’s the former then other lenders aren’t going to be interested in lending to you, as what you would effectively be doing is adding another tranche to your mortgage and banks don’t like splitting the mortgages between each other. Hence your only realistic option is UBS until your fixed term ends (all of them if you have multiple tranches). If it’s a variable rate, consult the market comparators recommended above.
Why would an old and tired roof be covered by insurance ?
Solar panels are a good idea, depending on the orientation of your roof, the cost will be recovered in the selling price of the house.
Banks do not split mortgages between themselves, if you are with UBS then you will either have to stay with them or change the full mortgage to another provider.
Depending on your circumstances this maybe difficult, pensioners with little revenue do not excite banks to increase the debt ration unfortunately.
Scaffolding costs what it costs, irrelevant if you use zinc or copper flashing. It you try and do a cheap job, that is what it will look like and you will not regain any of this when you come to sell but by doing the work properly and to a high standard, this will be reflected in the eventual sales price.
You could maybe consider selling and down-sizing.
You could possibly consider selling as a Viager property via Savinter.ch. This would allow you to stay in your house and give you some capital to use now.
If the roof was damaged by some external factor then there would be insurance coverage, if it started to leak due to age and wear and tear then the insurance will not cover it.
i've no reason to guess whether OP's roof is damaged or just old. it wasn't specified. hence the perfectly reasonable question of whether it was covered by insurance.
swiss house insurance covers a lot more than in most other countries, no questions asked, so i thought it's worth pointing it out!
House insurance don't cover ageing rooves. Our house dates from the 16C and the last roof was probably 1940s. Just needs constant repairs and tiles have become thin and easily broken.
We have thought about doing part of the roof in solar panels, integrated- to cut down on roofing cost, but strangely enough it would be even more expensive and if we add solar panels, as we have SW orientation- it would be on top.
