Ridge, verge and roofline work
Re-bedding and re-pointing ridge tiles, dry-ridge and dry-verge systems, and repairs to the roof edges.
The problem
Ridge and verge tiles are held on with mortar, and mortar has a shorter life than the roof under it. When it lets go, the wind gets under a ridge tile and takes it — usually onto a car or a neighbour's garden.
Modern practice is to move away from mortar-only ridges. A dry-ridge system clamps each tile to a batten with a ventilated roll underneath, so it does not rely on mortar and it lets the roof space breathe.
It is a good upgrade to do while a scaffold is already up for other work, and on an exposed roof — anything facing the prevailing south-westerly off the Channel — it is worth doing on its own.
What the job involves
- Check every ridge, hip and verge tile for movement by hand
- Strip the loose mortar bedding along the affected runs
- Refit tiles on a mechanical dry-ridge system — clamped, not just bedded
- Point up with a flexible compound rather than sand and cement where suitable
- Renew cracked or missing ridge and hip tiles with a match
- Seal the verges with a dry-verge unit or re-bed and undercloak the gable edge
