What is it?
Flat roof insulation is achieved by installing a rigid insulation board on top of a roof's existing weatherproof layer. It is also possible to insulate a flat roof from underneath if this option is not possible.
How does it work?
In an uninsulated home as much as 25% of all the heat produced is lost through the roof. The insulation material applied on top of the flat roof reduces this heat loss.
Flat roofs are most commonly found in top floor flats and apartments where the roof is jointly owned by all residents. In this situation, permission will need to be gained from all residents in the dwelling before work commences.
Flat roof insulation reduces energy bills, keeps a home warmer and lowers CO2 emissions.
According to the Energy Saving Trust, the potential annual savings on a home with a flat roof could be up to £180.
