Did very reasonable job, though was surprised that the lead is stuck on with what looks like bathroom sealant, at least its waterproof. Also had to convince one of the boys to reduce the width of the lead for aesthetic reasons as it would have looked just silly. Anyway, from the loft, no leaks visible so all good, and compared to the previous lot, much much better job. Lot of cowboys in this trade but this lot can be trusted. Contact with "the office" a little hit and miss, we still haven't got the written guarantee after nearly 4 months or had the loose tile looked at, but the result looks great and no problems with it.
