What to Consider When Installing Pitch Roof Insulation

When a building has a pitched roof, it is often best to insulate at rafter level rather than ceiling. This is the most popular and cost-effective way of insulating a pitched roof.

It is essential that a proper ventilation gap is left under the insulation to prevent moisture ingress and condensation which could cause timber damage and lead to rot.

There are various types of warm insulation materials that can be used in a pitched roof including mineral or glass wool, polystyrene slabs and spray foams. When installed correctly, these can help reduce up to 25% of heat loss from a roof and stabilise indoor temperatures throughout the year.

In addition to reducing heating bills, well-insulated pitched roofs can also reduce the amount of energy used by the building and therefore have a positive impact on the environment. In particular, insulated buildings can substantially cut carbon emissions and significantly reduce the demand for heating and cooling systems which can be sourced from fossil fuels.

The most important factor when insulating a pitched roof is to ensure that the construction of the roof is suitable. This is particularly important for older, traditional buildings which typically use permeable roofing materials such as tiles and slates to allow water vapor to escape. If this breathable quality is not retained when an insulated pitch roof is installed, it will likely not achieve the U value target set out in Building Regulations. Spray foam insulation
