Building work

We live next door to a boarding kennel and they have started reroofing a derelict "building" which butts onto our garden wall. They've been working on it several days now and I expected to see a lot of progress today as there's been lots of hammering but when I went and looked from our roof it doesn't look any different from yesterday!

We're hoping they are going to replace the whole roof as the red bit has lots of holes and looks quite an eyesore from our bedroom.
