Why a roof replacement can be regulated
GOV.UK’s current Building Regulations guidance specifically lists replacing roof coverings on pitched and flat roofs among projects that might need approval. The exact requirements depend on the work and building.
What to establish before work
• Whether Building Regulations approval is required.
• Who will deal with building control.
• Whether insulation or ventilation must be upgraded.
• Whether structural repairs change the scope.
• What completion or compliance evidence you will receive.
Planning is separate
A job that does not need planning permission can still need Building Regulations approval, and vice versa. Check both where the project changes appearance, structure or a protected building.
