This will give additional stability to the roof structure. So whether your new flat roof is to be made of timber concrete or felt or a combination of these materials you need to comply with flat roof building regulations.

For additional stability you can also use steel joists that are built into one or both of the walls. When installing or repairing a flat roof you must adhere to building regulations. Oak is considered a premium building material so an extension built with it will cost from 2 400 per m2. Expect to pay from around 1 800 per m2.
