How long does dry ridge last?

A dry-fixed ridge swaps the mortar bed for a mechanical system. A rail or batten is screwed along the apex of the roof, clips or brackets hold each capping tile to it, and a roll or strip beneath the capping closes the gap while letting the roof void breathe. A cap at each end finishes the run. The capping is generally the same kind of tile as the rest of the roof.

Dry-fixed ridge, hip and verge products have a test standard of their own, BS 8612, which sets performance requirements and test methods. It tells you a system has been assessed, not how many winters one installation will see. Some products add a vented section for roofs that need airflow at the top, and the data sheet lists which tile profiles each part fits. Years of service are a separate matter, settled by the maker's data sheet, the fixing and the weather the roof meets.

Think of a dry ridge as two layers of life. The capping is a roofing tile, and published expectations for roof tiles run long. Marley gives around 60 years for concrete tiles and adds that it is not something the maker is promising. The minimum Marley cites from the Building Research Establishment for clay is also 60 years, though old peg-tile roofs often tell a different story, and a reclaimed tile may be older than any figure.

The fittings are another matter. Clips, screws and seals differ from one product to the next, and the manufacturer's data sheet is where their expected performance is stated. Written cover from the maker or the contractor sets out what they will repair and the period it runs. It is no forecast of service life. Ask for the product name on the quote so you can look up its details yourself.

Three things count most. The first is the right system for the tile: a dry ridge made for one profile should not be forced onto another, and the data sheet says what each product suits. The second is the fixing. Every piece is held mechanically, to the maker's instructions, not left to rest on gravity and a snug fit. The third is the finish at ends and junctions, where the line of capping meets a verge, a hip or a chimney stack.

Aftercare is light, though not nil. Glance at the ridge from the ground after a gale, as you would any ridge. A rattle, a cap that has shifted or a gap at the end are all prompts for a check. A dry ridge does not rot or crumble the way mortar does, but it can loosen. Our guide to dry ridge systems shows how the parts go together.

With no mortar to crack, the warning signs look different. Listen for tapping or rattling in wind, which can mean a fixing has worked loose. Look for a capping piece sitting out of true, an end cap that has gone missing, or a skyline that no longer runs straight. A gap you can see daylight through along the join deserves a visit too.

None of this usually means the system has run its course. More often one fixing needs tightening, a clip needs replacing or a single piece needs renewing, which is a modest repair done in a short visit. If repeated trouble points to the wrong product or a poor fit for the tile, the survey will say so and suggest what would work better on that roof.

The case for dry ridge is that it removes the part that tires first, the mortar bed, and secures each piece mechanically. The case against is that on many roofs it costs more at the outset and changes the look of the apex a little. Checkatrade's guide, with a table updated September 2026, puts dry ridge on a typical semi-detached house at around £800 as a UK figure.

Which proves better value over time depends on the roof and on how it fails. You get the survey, then a written quote with a single total to weigh. A mortar ridge can be patched in small stages for years, while a dry system is usually kept going by renewing parts, and neither route is cheaper on every roof.
