Insulating a pitched roof above the rafters is the common method chosen for new builds and re roofing existing detached buildings as it provides superior thermal performance for the building.

Namely the insulation layers. In a warm pitched roof construction the thermal insulation is placed in the rafter line. When used in roofs tyvek and airguard membranes provide optimal protection of the thermal insulation and reduce the risk of interstitial condensation enhancing the energy efficiency of the building. An architect makes the usual decision of the pitch.

A cold deck roof is where the insulation is placed between the joists rafters or in between the ceiling joists in the case of a pitch roof. In a cold roof the insulation is applied between the rafters but in a warm roof the insulation is applied on top of the existing roof surface. The position of the insulation can be wholly above or partially between and above the rafter. This is where you consider the ventilation and sealing of the roof.

A typical roof pitch in the uk for a traditional house will be 40 50 but at most it can go up to 70. Covers an overview of flat and pitched roofs.
