Dry ridge systems use mechanical fixings and ventilated profiles that eliminate the cracking issues common to mortared ridges. They're now the default choice for new-build and re-ridge work across the UK.

The problem with mortared ridges

Traditional mortar bedding cracks. UK freeze-thaw cycles are relentless, and even well-executed mortar work typically needs re-pointing every 15–25 years. Cracked ridge mortar is a leading source of water ingress on older roofs.

How dry ridge works

Mechanically-fixed ridge tiles clip into an aluminium or plastic profile with an integrated ventilation strip. No mortar is used. The result is a permanent, ventilated ridge that doesn't crack and doesn't need re-pointing.

Retrofit considerations

Converting an existing mortared ridge to dry ridge is straightforward on most roofs. Typical cost is £30–£60 per linear metre. Best combined with a full roof clean while access equipment is on site.

Building regulations

Since 2015 UK building regulations effectively require dry ridge on new work — mortar bedding alone no longer meets the mechanical fixing requirement in BS 5534.

Frequently asked questions

How much does the work discussed in this guide typically cost in Nottingham?
For most Nottingham properties, a full soft wash with moss removal and biocide falls between £400 and £950. Biocide-only treatments start around £250. Restoration work with re-colouring is a separate service and starts around £1,600. We provide fixed written pricing after a free inspection.
What treatment schedule keeps moss under control in Nottinghamshire?
A full clean every 3–5 years is standard. Roofs under tree cover, on north-facing slopes, or in the wetter west of the county often benefit from a biocide top-up at 24 months to hold results between full cleans.
Should I choose soft wash or pressure washing?
Soft wash. Pressure washing damages the tile surface, voids many manufacturer warranties, and forces water into places it doesn't belong. Soft wash is slower but preserves roof life and delivers longer-lasting cleanliness — the only method we use on domestic tile and slate.
How long will results last on my Nottingham roof?
Expect 3–5 years of visibly clean tiles and up to 5–7 years of heavy-moss control with a mid-cycle biocide top-up. Regular gutter clearance and trimming overhanging branches extend results further.
