Dry Verge Systems › Cardiff › Guide
The verge is where the roof stops at a gable wall, and for generations it was finished with a bed of mortar. A dry verge does the same job with fixed units and no wet mix. Cardiff has gable ends of every age, from Victorian terrace ends to 1930s semis, so the choice comes up often.
What a mortar verge is and how it ages
A mortar verge beds the edge tiles on a strip of mortar, often with the tile ends pointed over the top. Done well it looks traditional and sits neatly. But mortar shrinks, cracks and absorbs water, and frost does the rest. On older Cardiff houses we regularly find verges that have lost chunks of mortar and let the edge tiles rock loose.
What a dry verge is
A dry verge replaces the mortar with mechanically fixed verge units and tile ends or caps. They are fixed to the tile maker's guidance, so the edge is held by fixings rather than by a bed of cement that can crack. Nothing wet is used, which means nothing to shrink, and the roof edge stays closed to weather, birds and insects.
- Edge tiles are fixed rather than bedded.
- No mortar to shrink, crack or fall out.
- Units close the roof edge against birds and insects.
- Fixings give the edge better wind resistance.
Which suits Cardiff houses better
Exposed gables on 1930s semis in Heath, Llanishen and Cyncoed take driven rain and wind off the Channel, and a dry verge copes with that better. On a Victorian terrace end in Roath or Canton, the choice is also about looks: some owners prefer the traditional line of mortar, and some dry systems copy it closely. Neither is wrong for every house.
When we would not recommend a dry verge
A dry verge only works if it suits the tile profile, so on some older or unusual tiles the units simply will not sit right. It also will not rescue a roof that is failing elsewhere, such as worn battens or tired tiles. We check on site, and if mortar is the sensible choice for that roof we say so.
What to ask before deciding
Ask what the verge is made from, how the units are fixed and whether they suit your tile profile. Ask what happens to the tiles at the edge, and what else the roof edge needs. The work may need planning or Building Regulations checks — we advise before work starts. A fair quote explains the system rather than just naming it.
- Do the units suit my tile profile?
- How are the edge tiles fixed down?
- What happens to the existing mortar and debris?
- Is anything else on the roof failing?

Common Questions
Is a dry verge more expensive than mortar?
We do not give figures in a guide, because it depends on the roof. The edge length, the tile type and the access all change the work. We look at the gable, explain the choice in plain terms and only then talk about the quote.
Can I switch from mortar to dry verge later?
Yes, usually. We remove the failed mortar, check the edge tiles and fit the dry system. The tile profile has to be compatible, which we check on site before saying yes, and we point out anything else at the edge that needs attention.
Will a dry verge look different from mortar?
Slightly, yes. A good dry verge sits neatly with a clean line, and some systems are made to resemble a mortar finish. We show you the options so you can judge how it will look on your house.
