Loose tiles at the very top of the roof/ridge, about 4 or 5 tiles need re-ciminting, it's a detached house.
I have a spinning stainless steel cowl which has become very noisy. I would like it serviced/repaired/replaced.
Remove roofing boards, insulate, replace boards, tar seal aon flat roof and garage roof.
Leaking roof to flat roof extension, may need to be re-done rather than repaired. Extension must be at least 20ft x 30ft and about 20 years old. Apparently walls have insulation, not sure about the roof...it's cold in there.
