How it should be recorded
Photographs and a clear area measurement help show why extra work is needed.
Local repair versus wider replacement
The choice depends on how far decay spreads and whether surrounding boards can hold fixings safely.

Questions about this topic
Can roof photographs answer every question about damaged sarking?
No. Clear photographs help, but hidden underlay, fixings, deck and water routes may still need close inspection.
Should I inspect damaged sarking by climbing onto the roof?
No. Roof work is dangerous even when the check seems quick. Photograph damaged sarking from ground level or a safe window and leave close access to trained people with the right equipment.
When should I request a written quote for damaged sarking?
Ask for a written quote after damaged sarking and the access needs have been assessed. It should set out the work, materials, exclusions and any likely extras.
