Replacing Conservatory Roof With Solid Roof Planning Permission

A change of use occurs when replacing a glass roof for a solid insulated roof as it causes the structure to be classed as permanent rather than temporary.

Replacing conservatory roof with solid roof planning permission.

The simple answer is no you do not planning permission to replace your conservatory roof with a solid tiled roof. In 2010 the planning regulations changed to allow conservatories to have a solid roof without the need for planning permission. When replacing a translucent conservatory roof for a solid roof you must obtain building regulatory approval. Replacing an old glass or polycarbonate conservatory roof with a new solid tiled roof does not require planning permission but it does require building regulatory approval.

This is because adding a solid roof to your conservatory changes its classification from a temporary structure to a permanent one. There are just some limits and conditions regarding placement and size which you can find details of on the government s planning portal. This may necessitate planning permission. Replacing your conservatory roof shouldn t require building regulation approval so long as you are not blocking ladder access to a loft or roof extension window especially if it was designed as a fire escape for example.

Prior to this change in regulation the law stated that to be considered a conservatory 75 of the roof needed to be translucent in order for the building to be constructed without planning permission.
