What the scheme covers

Not all roof refurbishment work is covered by the Competent Person Scheme. A roof that is being replaced or refurbished, on a like for like basis, is covered by the scheme and can be self-certified. A new roof or a change to the roof structure must be registered with building control.

What is covered by the NFRC Competent Person Scheme?

Registered contractors can self-certify their roof refurbishment work when 50% or more of the roof is being refurbished, for the following roofing categories:
  • Slating and Tiling and all other pitched works (including Shingles and Shakes).
  • Felt, Single Ply and GRP.
  • Fully supported lead, copper, zinc and standing-seam aluminium.
  • Liquid Applied Waterproofing.
  • Mastic Asphalt (incl. Hot Melt).
  • Reinforced Bitumen Membranes.
  • Sheeting.
  • Provision of roof lights—provided they are only inserted between rafters or on a like-for-like basis.

The following types of roof refurbishment work are not covered by the Competent Person Scheme and must go through local authority building control.

  • Where less than 50% of the roof is being replaced, as this falls out of the scope of Approved Document L1B
  • Any solar or photovoltaic installation
  • The following areas which fall under the remit of Building Control:
    • Work on trussed rafters.
    • Any structural glazed roof such as atriums.
    • New build work.
    • Structural work, unless like-for-like, e.g. rafters.
