Tradesmen, to gripe or not?

I don't know if I've got a good deal from the roofers.
They finish the roof barring pointing up to the slates on one of the gables, they where going to quote for the pointing both gable ends. However they left site leaving some scafolding in the front garden.
The breather mebrane is holed in some places and badly fixed also full of slate chippings in parts.
The woodwork around veluxs is shody (certainly not up to my standard and not like the pictures in the fitting instructions)
The wooden gutting at the front of the house and now fallen off, and plastic guttering round the back has a chunck out.
On the plus side, I've not had any leaks and I've still got a £1000 retainer. I think I'll just wait to see if they want there scaffold tower and money before I make my mind up to gripe.
