Widely different roofing quotes. What's a reasonable price?

[Colin Green]

We discovered a leaking roof last night and have had two quotes so far (two more to come). £1800 and £4700, which is confusing.

A bit of the front of the house sticks out and has a gable end, so there are two valleys. Both quotes are to replace the tile valleys with plastic and replace the felt, then reuse the same tiles and replace any that break. Both said a scaffold tower would be about £300. The roof is probably 4m wide including the overhangs and sticks out by 1m.

What would be a fair price for the job, and so which one is off the mark? I'm in the midlands.

I got two quotes from two roofing companies to replace some rotten sections of sofits and fascias, pvc cladding, new guttering and downpipe. One quote was £3500, one was £1250. I went with cheapest and they did a good job.
