Also is your roofer accredited? Does he know what he is talking about? There are a lot of cowboys out there who will tell you things need doing on your roof, knowing full well you are not going to go up a ladder to inspect the roof for yourself. In what way are they "in a bad way"? Are they cracked, or have they slipped? You should be able to see for yourself from the ground - borrow a pair of binoculars from a friend to have a good look.
