Dry Verge Systems › St Mellons
The verge is the edge of the roof at a gable end, and on older mortar-bedded roofs it is often the first part to fail. Mortar cracks, shrinks and drops out, leaving tile ends loose and the roof edge open to wind and weather. A dry verge replaces that mortar with fixed units.
Many St Mellons estates have gable-ended houses and end-of-terrace homes with long verges exposed on one side. We fit dry verge on new roofs, on re-roofs and as a repair where mortar has failed, always following the tile maker's guidance and checking the tile profile on site first.

Verges on St Mellons houses
Houses built from the 1970s to the 2000s in Old St Mellons, Pontprennau and Castleton often have concrete tiles with a mortar-bedded verge. Decades of wind and frost leave hairline cracks, then gaps, and you can see crumbs of mortar on paths or in the gutter below the gable. That is the usual sign the verge needs attention. We look at that first when we visit.
East Cardiff is open and breezy, with the Severn Estuary air coming in over flat ground, and gable ends take the full force. Estates such as Rumney, Trowbridge and Llanrumney have many end-of-terrace and semi-detached homes where the verge faces the weather directly. We see this on most gable-ended house types. We check those first.
Where the mortar has failed, birds and insects can get in at the roof edge, and wind can start lifting the tile ends. A dry verge cures that edge. It is not a fix for a roof that is failing elsewhere, and we tell you if the tiles or battens need attention first. Caught early, a failing edge is a simpler job, which is why we look at it closely. Ask us.
Dry verge work we do in St Mellons
- New roof dry verge — On a new roof we fix the verge units and tile ends as the tiles go on, so the edge is wind-resistant from day one.
- Re-roof verge fitting — When we re-roof a gable-ended house we replace the old mortar bedding with a dry verge so the new edge matches the new covering.
- Repair of failed mortar verges — Where mortar has cracked or fallen out, we strip the old bedding and fit dry verge units along the affected edges.
- Verge unit and tile-end replacement — Cracked, slipped or missing verge tiles and end caps are replaced and fixed mechanically rather than just re-bedded in mortar.
- Checking tile compatibility — Dry verge depends on the tile profile, so we measure up on site and tell you whether the system suits your roof.
- Gable edge and bargeboard checks — We look at the fascia, bargeboards and sarking at the gable edge, and report anything that needs attention before the verge is fitted.
How we fit a dry verge here
We start with a close look at the gable edge from the ground and then on the roof. We check the tile type, the condition of the battens and how much of the old mortar has gone, then explain whether a dry verge will fit your tiles. Nothing is started without your say-so.
The old mortar is removed, the verge units and tile ends are fixed mechanically to the tile maker's guidance, and the edge is finished neat and clean. Nothing wet goes in, so there is no mortar to crack later. We clear all debris from the gutter and drive before we leave. Everything is left tidy.
Dry Verge Systems Guides for St Mellons
Dry Verge Systems in St Mellons — Common Questions
Why does the verge on my St Mellons house keep cracking?
Mortar shrinks and cracks with wind, rain and frost, and east Cardiff gable ends are well exposed. Once cracks open, water gets in and the tile ends loosen. A dry verge removes the mortar, so there is nothing left to crack.
Can a dry verge be fitted to my existing roof?
Often, yes, but it depends on the tile profile and the state of the roof edge. We check on site and tell you whether a dry verge suits your tiles, or whether other work should be done first.
Will a dry verge stop birds and insects getting in?
It helps a lot. Failed mortar leaves gaps at the roof edge where birds and insects can enter. Dry verge units close that edge off, though a roof failing elsewhere would need its own repairs.
Is a dry verge better in the wind?
It resists wind well at the edge, where roofs take the most uplift. The units and tile ends are mechanically fixed to the maker's guidance, so they do not rely on mortar staying bonded to the tile.
Do I need planning permission for a dry verge?
Usually a like-for-like repair is straightforward, but a dry verge may need planning or Building Regulations checks, and we advise before work starts. Call us for a proper look and we will talk it through.
