Different materials are used in the construction of a roof but usually the finishing is done by using roof tiles.

The pitch of the roof is decided based on the weather conditions.
Insulating the roof above the rafters is known as warm roof insulation as the rafters are brought into the insulated envelope of the building.
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.
For example in the areas of high snowfall and rainfall the roof pitch can be significantly longer as this will allow the snow to fall off the roof the roof.

Ventilation is required for these roofs.
A warm roof building will make the entire structure of the building warm in an attempt to avoid any cold bridging.
There are many benefits to this type of construction including making a home more energy efficient and minimizing the thermal bridge at the eaves.
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.
