Getting a dormer roof added to your property is a great way to add extra space with a loft conversion. The structures add plenty of extra natural light, extra head height and a sense of openness to the room. 

Dormer roofs are structural extensions, which are formed outwards on the existing sloping roof. Their multiple benefits make them an extremely popular choice - and for good reason. 

Dormer Roof FAQs

Do I need to get planning permission for a dormer roof?

There are some reasons which mean that you would need planning permission. For example, if your dormer roof exceeds the size that falls under permitted development, you would need to apply for planning permission. Or, if it faces a highway or the materials don’t match up with the other properties in the area. 

Will I need to follow building regulations?

Yes, all construction work including extensions and conversions must follow building regulations. Your site will be visited by an inspector at multiple points of the process, and they will be making sure that you are following the correct procedures for health and safety and best practice.
