Without adequate insulation, a quarter of heat can leak through the roof. In this article, we explore the importance of insulation and how a homeowner can identify whether their roof is meeting adequate insulation standards.


Why We Insulate

Insulation slows the transfer of heat, which is useful for both hot and cold climates. On hot days, it slows the entrance of heat into the building. On cold days, it slows the departure of heat from the building.

When it comes to our roofs, lofts and attics, we insulate to control the transfer of heat, which is an affordable and effective way to reduce energy loss and heating bills.


Is Your Roof Leaking?

If your roof isn’t providing adequate insulation, there are a few ways to find out. If your home is often going from cold to hot, especially with different temperatures in different rooms, it is likely your home is not well insulated. Effective insulation also reduces energy bills. If your energy bills are exuberant, it is likely that there is a leak somewhere in your home.

Not only does poor insulation let heat of your home, but it also doesn’t protect against the elements. If your roof has water leaks, it is likely a symptom of poor insulation.


How to Insulate Your Roof

Once you identify whether your roof requires insulation, the next step is to insulate it. Roof insulation involves creating a barrier of material in your roof space laid either between the joists or the rafters.

The type of roof you have impacts the insulation it will need. Flat and dormer roofs are challenging to insulate, whereas sloping roofs are more straightforward. From there, there is a decision between having a cold or a warm loft. A cold loft involves insulating above the ceiling of the top storey, whereas a warm loft insulates just under the roof. A warm loft is generally more expensive, but also more effective with heat retention.

The cold loft option is easiest to install as a DIY project, however, if you are interested in a warm loft and your roof is not sloped, it is recommended that you ask a professional to carry out the insulation for you.

This especially applies if your roof is damp or difficult to enter.



Insulating your roof can be expensive, but it will pay itself back over the coming years. Considering that up to 25% of heat leaks from your roof if it isn’t well-insulated, it is truly worth the investment.
