Roof

If you want to carry out repairs on or re-cover an existing pitched or flat roof you will not normally need to submit a building control application if:
- Less than 25 per cent of the total ‘building envelope’ (walls, floor, roof, windows, door, roof windows and roof-lights) is affected; and
- Less than 50 per cent of the roof is affected.

However, you will need approval if:
- You exceed the limits stated above (in which case there may also be further considerations that could require work to the entire roof, such as ensuring the thermal insulation is sufficient)
- You carry out structural alterations
- The performance of any new covering will be significantly different to that of the existing covering in the event of a fire.
- You use a new covering material which increases the weight of the roof covering by 15 per cent or more

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