Hi Gerard, It is in your interest to see the roofing companies up to date insurance documents, this should be a combined liability policy, covering employers liability and public liability. If they can not provide you with details, I would advise you to get another couple of quotes from other roofing contractors. The insurance for Roofers does not come cheap, due to the high risks involved, which is relative to the amount of cover provided by the insurance company. I would also check their Health and Safety policy. Good luck.
