Flat Roof Insulation

Why insulate?

A quarter of heat is lost through the roof in an uninsulated home. Insulating your flat roof is an effective way to reduce heat loss and reduce your heating bills.

Flat roofs are most easily insulated from above the existing roof structure. A surveyor will assess the flat roof’s condition to determine if the insultation is suitable.

How is it installed?

Firstly, scaffolding is erected around the roof to allow access. The installer then removes the original guttering and will build a new timber frame around the roof to accommodate for the height of new insulation boards. Once the frame is fitted, the installer then fits new soffits, fascia and guttering to weatherproof the new layer. Thick insulation boards will then be laid on top of the existing roof felt, which acts as a ‘vapour barrier’ to ensure the roof can breathe to minimise any risk of condensation and moisture. Finally, the new insulation boards are covered by a protective weatherproof layer called a ‘membrane’. This layer will expand and contract with temperature changes, offering better performance and a longer lifespan than traditional felts.

How long does it take to install?

The installation process typically takes 2 to 3 days and once installed, will be guaranteed for 25 years.

What will it cost me?

If you are an owner-occupier and meet the grant criteria, then it will cost you absolutely nothing. The grant will cover the complete cost of the installation.

Where’s the catch?

There isn’t one. Any enquiry you make will be without obligation, you don’t have to have the work done until you are completely happy with the plan.
