Dry Verge Systems › Maesteg › Guide
Mortar verges are common on Maesteg terraces and older houses, and many have been standing for decades. Mortar is hard and rigid, while a roof moves with heat, frost and wind, so cracks are only a matter of time. What matters is what happens once the bedding starts to go.
How a mortar verge starts to fail
Hairline cracks appear first, usually where the mortar meets the tile. Rain gets into them, and in a valley with plenty of frost the water freezes and widens the gap. Over a few winters pieces drop away, and you may find crumbs of grey mortar in the yard or on the path. The cracking is quicker on gable ends that face the prevailing weather up the valley.
What follows once it has gone
With the bedding gone, the edge tiles lose their support. Wind can lift them and rain can blow in behind them. Water enters the roof edge, soaks the timber at the gable and can show as damp staining on the bedroom wall below. Birds and insects also use the gap to get into the roof edge, and a loose verge tile can slide off in a gale, which is a risk to anyone walking beneath.
What you can check from the ground
You do not need to go anywhere near the roof. Look up from the pavement or garden at the gable end. If the line of the verge looks wavy, if there is a visible gap, or if you can see daylight or loose pieces, it is time to call us for a proper look.
- Gaps or cracks along the gable edge
- Mortar crumbs on the path or ground
- Damp marks on the gable wall inside
- A tile sitting out of line at the edge
Repair or replace
Small, local failures can sometimes be re-bedded, but if the mortar is failing along the whole edge it usually makes sense to replace it. A dry verge, fixed mechanically with verge units and tile-ends, removes the mortar altogether, so the same problem does not return. We give you the choice and say plainly which one we would put on our own roof.
What we do on site
We remove the loose bedding, check the edge tiles and the timber below, and fit the new verge. If the tile profile does not suit a dry system we say so and propose another way. Any wider roof faults we spot, we tell you about before they become leaks. The whole edge is left tidy, with the old bedding taken away from the site.

Common Questions
How quickly should a failed mortar verge be repaired?
Sooner is better. Once mortar is cracked, frost and rain widen the damage each winter, and the edge tiles become loose. A prompt repair is simpler and easier to carry out than waiting until tiles come away in a storm.
Can a mortar verge just be patched?
A small patch may hold if the failure is limited to one spot. If the cracking runs along much of the edge, patching tends to be short-lived, and replacing the whole verge with a dry system is the sounder choice.
Is a loose verge dangerous?
It can be. Loose edge tiles can slip in high wind and fall to the ground below. If you see tiles hanging at a gable end, keep clear of the area beneath and call us so we can make it safe.
