MIL needs the felt on her 20+ year old flat roof replacing. Underlying timber is apparently sound, just needs felt and bitumen (or whatever the best way to do it is). What sort of price per square metre should she be looking at?
Also, of the two people that have had a look already, one says "I don't put stones on top", the other says "You must have stones on top". Not sure what they mean by that (the gritty stuff on top?). Is it necessary or for visual appeal only?
