Dry Verge Systems

The gable edge, mechanically fixed — no mortar left to crack and fall.

The verge is the roof's edge along a gable, and traditionally the end tiles there were bedded on mortar. It's the same story as mortared ridges: rigid mortar on a moving roof, worked by frost until it cracks, then chunks in the garden and gaps at the tile edges — into which wind gets a purchase and birds get a home. Cracked verges are among the most common defects we see on gable-ended houses.

A dry verge system ends the cycle: interlocking uPVC caps fix over each end tile mechanically — screwed, not stuck — sealing the edge against wind uplift, rain and wildlife with nothing that can crack, and giving a clean continuous line to the gable. It's why every volume housebuilder fits dry verge as standard, and has for years; retrofitting brings an older roof up to the same detail.

The natural pairing is dry ridge: if your verges' mortar has failed, the ridge mortar is usually of the same vintage, and one access setup does both.

Repair options

Repair or replace

The traditional alternative — repointing the verge in fresh mortar — remains right for conservation contexts and looks the part on period gables, at the cost of being a repeating job. On an ordinary house the arithmetic favours dry verge decisively: comparable cost to a proper repoint, and you pay it once. What we won't do is the half-measure of mortar smeared over the old bedding — it's the shortest-lived repair on the roof. If tiles at your verge have already slipped from failed bedding, that's a tile refix done as part of the same job.

Common questions

Frequently asked

Will dry verge fit my roof? +

Systems exist for the vast majority of tile profiles and for slate; the survey confirms which. The occasional exceptions are unusual tile shapes and some interloc profiles, where a hybrid or traditional detail is the honest answer — we'll tell you either way from the first look.

Does dry verge look plastic and modern on an older house? +

From the ground, a colour-matched dry verge reads as a neat shadow line — most people never notice the change except that the crumbling mortar has gone. On a genuinely characterful gable where the mortar detail matters visually, we'll say so and quote traditional repointing instead.

Can just one gable be done? +

Certainly — verges fail with exposure, so the weather-side gable often goes years before its sheltered twin. That said, access is the main cost, so if both sides' mortar is the same age, doing both (and often the ridge) in one visit is where the value sits.
