Got a guy on the roof at the moment fixing some tiles that came off with the recent gales we've had. He was hired by my Mum after he cold-called at the house offering his services.
He wasn't here 10 minutes, when he starts telling my Mum how "unsafe the chimney stack is", and how he can fix it £580! (A bit of a jump from the £150 job he was hired for!

) And my poor Mum was talked into it!
Thankfully, my Dad came home before he could start work on the chimney and brought the additions to a screeching halt, so he's only doing, (and probably botching), the job he was hired for.
This is not going to end well!

So in preparation for the inevitable cock-up, can anyone here recommend a good roofer please?
