Jason refelted my shed roof in a couple of hours, supplying all the materials to do so. Very curteous and the workmanship appears sound (since it's a waterproofing for a roof, time will tell how successful it was!).
Only two very minor gripes prevent a 5 rating: 1. His original quote did not include a 'sourcing fee' for the materials (this was ?20 extra); 2. He did not remove the remnants of the old felt, etc. after the job was finished.
Otherwise, very good job and I would recommend.
