What ridge bedding does
Bedding is the mortar base that positions and supports ridge caps along ridges, hips and gables. Crumbling, displaced or hollow bedding may no longer provide a stable base.
- Supports ridge-cap position
- Forms the underlying mortar base
- Must be sound before finishing
What flexible pointing does
Pointing is the exposed flexible finish applied along ridge-cap edges. It helps seal the bedding and accommodate normal roof movement when installed over a suitable base.
- Seals exposed bedding edges
- Creates the visible finish
- Moves more readily than rigid mortar
When rebedding may be required
Loose ridge caps, badly failed mortar or widespread loss of support may require removal and rebedding before new pointing is applied. The extent should be confirmed during inspection.
- Loose or displaced ridge caps
- Crumbling mortar base
- Sections no longer properly supported
What a clear quote should say
The quotation should distinguish full rebedding, local bedding repairs and repointing. It should identify which ridges, hips or gables are included rather than relying on a broad label.
- Areas included
- Bedding work versus pointing only
- Product and workmanship coverage

These completed projects show how the work changes with the roof material and the faults found.
- Doncaster rebedding and repointing
Failed bedding required the ridge and hip caps to be lifted and rebedded before flexible pointing was applied.
