If you want to carry out repairs to, or to recover, less than 25 per cent of the surface area of a pitched or flat roof you will not normally require Building Regulations approval, unless you carry out any of the following works:
- use a new covering material which increases the weight of the roof covering by 15 per cent or more
- Structural alterations
- use a new covering that will have a significantly different performance to that of the existing covering in the event of a fire.

If you are replacing/repairing more than 25 per cent of the roof area, the thermal insulation to the roof would normally have to be improved so you would need to submit an application.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to the relevant Competent Person Schemes.

Protected Species
