Hi Nonick,

You did not specify if is an industrial building, storage building  or residential building.  A lot rides on the building superstructure supporting the roof, which will determine which insulation is the easiest to install.

The least expensive insulation is fiberglass batt, its available in various "R" ratings and is relatively easy to install, if you can live with those itchy fiberglass fibers.

Rigid polystyrene insulation offers high "R" values and is easier to install but more expensive. If the insulation is to be exposed, it makes for a much neater job.

If its a large area, consider spray foam insulation, spray foam offers the best coverage and is the easiest to install , just spray it on, however this job is best left to a professional who has the expertise and equipment to do the job right.
