@EmoIsntDead I've had a slight roof leak in two places for two years, no dripping just small damp patches. I've had various roofers round to quote, - it was never urgent, so I bided my time.
I had four come round, all of them agreed it was due to disrepair of flashing around the chimney stack and also along one side of the roof slope (terraced house). All of them said it'd have to be full scaffold front and back.
Two of the four didn't get as far as a quote. One said he was too busy and another forgot to quote and said he'd have to return for another look. The two who did quote, it was in the region of £5,000.
And I thought WTF, it's just a bit of flashing and patching up with concrete.
So I waited.
Then, this year, I was recommended a roofer, by someone who said he'd gone to school with the roofer, and was shocked at the £5K quotes.
This roofer quoted £950 (no VAT), didn't need full scaffold, just a scaffold platform on top of a flat roof at the back. Scaffold cost £400, roofer labour £550.
He did the work in a day and a half.
Anyway, just to say, quotes can often be wildly unreasonable.
(A neighbour a few doors down [elderly female] stupidly paid £7K for repair of a small roof leak, the job took two days, she paid, and the roof still leaks).
