Not all Part Q Rooflights are the same

What is Part Q?

Part Q Building Regulation details that any new build property should have in place reasonable provision to resist unauthorised access to (a) any dwelling; (b) any part of a building from which access can be gain to a flat within the building.

Within the Part Q document it defines easily accessible as:

  • A window within 2m vertically of a flat or sloping roof (with a pitch of less than 30 degrees) that is within 3.5m of ground level.
  • A window or doorway, any part of which is within 2m vertically of an accessible level surface such as ground or basement level, or an access balcony.

Part Q and Rooflights

Generally if a roof window is installed on a pitched roof it will fall outside of the guidelines of ‘easily accessible’, however for rooflights this is not the case.

If the property has a flat roof extension it is more likely that the flat roof will be easily accessible and therefore any rooflights installed must meet the security testing required.
