Cost of Pitched Roof Insulation
A lot of homes have pitched roofs. If your home is one of those, you may choose to install a modest loft insulation positioned right on top of the joists.

Sydney roofers Vertec state that to insulate a roof, it is important that you use the right insulation materials to add between the rafters. This addition ensures that there is enough ventilation left behind the insulation to protect the rafters from excessive moisture which could cause some damages if not controlled.
The materials commonly added to the rafters as mentioned above include; polystyrene insulation panels. This is often supported with foil cut to fitting sizes; mineral or fiberglass lagging, which is often held in position with wooden slats; you could also use expanded polystyrene products that unfold to occupy the space. In some unique circumstances, spray foam can serve the same purpose.
On average, insulation panels which are the most popular roof insulation costs about £25 per square meter. Spray foam insulation on the other hand costs £30 per square meter. With these, we estimate about £400 to £500 to be the average on prices for roof insulation in most homes.

One way is to install warm deck insulation on top of the roof decking and underneath the weather-proof pane. Cold deck insulation on the other hand is placed under the joists, with ample space for ventilation.
Another option is inverted roof insulation. Here, you could install the insulation on top of the weather-proof layer, then add a new layer, for instance gravel, on the exterior part of the roof.
