insulation for the roof can significantly reduce heating and cooling costs, as well as the wear and tear on your HVAC system. It is therefore an important part of any home improvement project and should be done by a trained professional if possible.

The type of insulation for your roof depends on the design and structure of the roof, as well as your energy efficiency goals. For example, the presence of attic spaces, dormers and skylights may require insulation techniques that are different from those used for pitched or flat roofs. It is also a good idea to consider your climate zone when choosing an insulation material. Insulation with a higher R-value is suitable for colder climates.

Effective Strategies: Insulation for the Roof

Depending on the design of your roof, you can choose to insulate it either from the inside or the outside. In this case, you can opt for mineral wool (either glass or rock wool) or cellulose fiber insulation boards. These are usually hung on battens of wood attached to and across the rafters. Polystyrene slabs that are sometimes foil-covered can also be fitted, although they must be cut to size.

Another option is to use closed-cell spray polyurethane foam on the underside of the attic ceiling sheathing. This creates a conditioned attic and is highly effective in every climate. It is also water-resistant and does not attract rodents. It is recommended to always consult the instructions provided by your chosen spray insulation product before applying it.
