A leaking roof prompted me to worry a lot about my house; worries not made easier by have to be away so much. It was clear the problem could be much worse than one loose tile, and I had to find a roofer`I could trust (I once had one nick the lead strip that sealed my sky-light). After a lot of searching I got a good roofer called Mick, who fixed the leak yesterday. I need to spend a lot more money on getting all the slates re-laid at some point, but at least I know the full measure and rough price of it now.
