Cost: traditional timber roof frame
Compare a defined project: design, specified timber, fabrication, connections, anchors, lifting and installation. Separate framing, covering, insulation and interior conversion. For partial renovation, identify affected members rather than applying an average to the entire roof area.
Editorial update on 18 September 2026
Compare the proposed frame
Request design scope, timber references, fabricated members and connections. Check that the same openings and intended loads are included.
Price renovation by intervention
Map retained, repaired and replaced members with access conditions. Separate temporary supports, stripping and reinstatement of roofing opened for the work.
Identify additional work
Check whether covering, insulation, floor, stairs and finishes are included. Clarify transport, lifting, protection and waste. Area prices require the same measurement basis and scope.

Frequently asked questions
Does a traditional frame make the loft habitable?
Not automatically. Assess space, floor, access and the complete conversion.
Is oak always best?
Selection must suit project requirements and exposure, not a universal species ranking.
Must all new timber be treated?
Ask for protection to be justified for the timber and use; do not select treatment by default.
Is repair always cheaper than replacement?
Compare options after assessment, including access, temporary support and related work.
