David reroof using existing tiles

The project is to reroof the house.
Use as many ok tiles of the Stafforshire Blues as possible.
length and width of house is 6.6 Mts x 8.90 Mts (1.2) = 69.69 Mts
Could do with a U value and condensation report for the use of the most appropiate Super FOIL.
Also a cost of delivery.
Specification sheet and suggested means of application to pass onto our roofers.
I use an Imac and apple phone for photos does the system allow them to be dowloaded?
