Currently getting a new extension built to rear of flat roof garage.
Going to get a whole new flat roof, roofer is advising to use felt with 120mm insulation but others have suggested using fibre roof as it will keep the new extension area warm.
Looking for advice on what to go for and costs involved or extra cost on top of felt
