Re-roofing and aluminium guttering

FifiMoor

Hi there, I was wondering if people think that this quote seems fair for the work. I am in Manchester. We have a double story extension and added onto that a single story lean to (kitchen extension). The lean to section (measuring approx. 9m2) needs reroofing, using the old slates but new battons, lead flashing an felting. Plus we want aluminium powder coated guttering, 2 lengths, 1 of approx. 2.5m and one 3m plus aluminium hoppers and down pipes (of around 2.5m and 5m). We have been quoted approx. £2K. Does this seem about right?
Thanks in advance.
