With exterior insulation the tiles come off and an insulation package goes on top of the structure, after which the covering returns. The attic stays fully usable and the roof frame remains visible — the clean solution for a lived-in attic.

As a standalone job expect ± € 100 to € 180 per m² of roof surface; for a complete home € 6,000 to € 16,000. Combined with a roof replacement, double scaffolding and stripping work disappears and the surcharge drops sharply.

Insulation lowers heating costs permanently. Subsidy schemes also exist for insulation measures — ask the roofer or your municipality about current options before you sign.
