Garage Roof Repairs/Replacement West Yorkshire

[Erijaso]

My garage roof needs some repair/replacement. I've got a couple of names from the yellow pages, but wonder if anyone had used a company in the West Yorkshire area, who they can recommend.

It's 30 foot by 40 foot and it looks like asbestos (ouch that will cost to dispose) corrugated sheeting.

Any recommendations, or people in the trade could give me an indication for full replacement?
