Work on the Roof

You do not normally need to apply for planning permission to re-roof your house or to insert roof lights or skylights.

New rules apply from 1 October 2008. These allow for roof alterations without the need for planning permission, subject to the following limits and conditions:

  • Any alteration to project no more than 150 millimetres from the existing roof plane.
  • No alteration to be higher than the highest part of the roof.
  • Side facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
