Can You Fit Dry Verge Yourself?

At a gable end the roof stops just short of the end wall, and the strip of tiles that finishes that slope is the verge. A dry verge dresses it with caps or long lengths held on by screws or clips, so there is no mortar to mix. That sounds like a tidy afternoon with a drill. The trouble is where the work happens: every fixing goes in at the outermost edge of a sloping roof, with the ground right beside you.

A ladder leant on the gable cannot reach the whole line, and it leaves you nothing to hold while both hands are busy. The edge tiles are also the least supported on the roof, so they shift or crack under a boot. On a two-storey house the sensible way up is scaffold or a proper tower with edge protection, which is why access can cost as much as the parts. One slip at the verge ends on the path below. Our answer on dry verge without scaffolding looks at which houses can manage with less.

The parts you can see are only half the job. Beneath the old mortar sits the undercloak, a slim board, fibre cement strip or tile slip that carries the last row of tiles and gives the new system something firm to sit on. If it has rotted or cracked, the new verge will rattle or lift however well it is screwed down. Behind it are the batten ends, and these have to be sound enough to take a fixing too.

Finding these faults means stripping the old edge, looking closely and deciding what to renew before anything new goes on. Each maker has its own parts, its own fixing pattern and its own instructions, and a mix of brands rarely works. BS 8612 sets out the tests a dry system must pass at verge, hip and ridge, so a roofer can point to a tested product. Marley adds that installing to BS 5534 is not required by law, but a roofer chooses to work to that code of practice because it is the recognised method for fixing tiles. Guessing at these details from a ladder is how a verge ends up loose within a season.

As a national guide, Checkatrade's September 2026 dry verge page gives approximately £10 to £25 per linear metre, parts and labour together, with a semi-detached house coming to about £875 in all. Treat that as a yardstick only. On your own house the price moves with the length of verge, the height of the eaves, what the survey finds under the old mortar and how the roof is reached. Check whether any quote includes VAT.

Scaffold is the biggest variable. Checkatrade's September 2026 fascia and soffit table shows roughly £300 to £600 a week to scaffold one elevation. Poles that stand over the pavement or road call for a licence from the highway authority, which we sort out alongside the scaffolder, while your own drive or garden needs no licence. The gutters, fascias or ridge may share the same scaffold, so ask whether anything nearby is worth doing while it is up. A tower costs less than full scaffold but only suits a short, low edge.

We look at the roof first, share photos of the verge and what sits beneath it, and give one written total price afterwards.

There is useful work to do without leaving the garden. Stroll round the outside and study each gable edge in turn. Note any mortar that has cracked, dropped or gone green, any edge tile that sits proud or looks loose, and any gap where light or birds could get in. A phone photo from the ground, zoomed in, lets a roofer see the pattern before the survey.

Measure each verge if you can, from ridge down to eaves, and mention anything that leaks inside, such as a stain on the gable wall in the loft. Find out whether the original roof has a warranty, since a repair by someone else can affect it, and look out for spare tiles stored in the garage or shed, since a roofer can use them to match the edge. Keep any photos of the house taken before the work, as they show how the verge looked.

All of this saves time on the day and keeps you off the roof. Our guide to what a dry verge system is explains the parts, and the dry ridge and dry verge page covers the wider work.
