Cost: roof frame strengthening or repair
The price must relate to a designed solution following assessment. Separate investigation, calculations, temporary safety measures, repair and reinstatement. The number of visible members alone cannot classify a project as a simple or major repair.
Editorial update on 18 September 2026
Price investigation and design
Check visits, inspection openings, measurements, reporting and calculations. Assign reinstatement of openings. Distinguish an initial estimate from the works price after investigation.
Compare structural scope
Request member identification, materials, connections and support work. Check temporary safety measures, stripping and roof reinstatement. Agree handling of further findings before execution.
Include building consequences
Separate insulation, ceilings, finishes, access and waste. Clarify occupation restrictions and phasing. Compare solutions for the same future use, not only the currently visible defect.

Frequently asked questions
Does a crack require beam replacement?
Appearance alone cannot decide. Have the member, connections and context assessed.
Is an engineer only needed above a certain member count?
No member-count threshold is given here. Define expertise and investigation around the actual issue.
Can I stay beneath the work area?
Do not assume so. Site managers must establish access and occupation restrictions.
Does timber treatment replace strengthening?
No. Treating an infestation and establishing structural resistance answer different questions.
