Watertight

We have a new roof! It was supposed to go on a couple of weeks ago but the rains delayed things. This morning, however, Tom the roofer and ten of his best men turned up bright and early to begin stripping off the old roof. This is the bit where you hold your breath in case they discover soggy boards or other costly problems but we were fine. Fine that is until the police turned up and ordered them to stop work. It seems we woke someone up with all the banging and they complained and it transpires that there is an ordinance prohibiting work on a Saturday in our village. Unfortunately, nobody told us about this policy.
Anyway by the time the police got here (we are two doors down from the police station) the roof was off and there was no way that Tom was leaving us exposed to the elements over the weekend. So, a call to the Chief of Police and another to the neighbour who made the complaint and Tom got a citation but work resumed. Can I just say to the person we annoyed that we are truly sorry. If the police had let us know who it was we would have apologised in person and sent you a bottle of champagne. Why don't they give you a rule-book when you move to a new area? It would make life so much simpler. We apologised to all the neighbors who came out to look at the new roof but they disclaimed responsibility and only a couple knew about the no work on Saturday rule.
The roof looks great; pewter grey shingles that match the bluestone around the house, not too blue and not so dark it looks squat. We have had some rain since and high winds and we seem to be watertight and windproof, which is what we were aiming for. It also seems to be quieter when it rains. Can anyone explain that to me?
