Should we insulate between roof rafters?

We are renovating a 1930's semi which has a tiled pitched roof with no felt. Should we insulate between the rafters with kingspan etc as well as using Rockwool in the loft floor to gain a better U rating? The loft is only to be used for storage. Thanks

No you are wasting money and could potentially cause condensation.

So long as you have the required depth of insulation between and over rafters you will not gain much by increasing the existing set up.
