Dry Ridge · York & Yorkshire
Ridge tiles fixed mechanically to the roof structure, with proper ventilation built in, meeting current British Standards. So the ridge stops being the reason a Yorkshire storm makes the news.

What we do
A dry ridge system replaces the traditional bed of cement mortar under ridge tiles with a mechanical fixing kit, screws, clips and a ridge roll, that ties each tile directly to the roof structure. It's the current Building Regs and BS 5534 compliant method.
Homeowners with a mortar-bedded ridge that's cracking or lifting, anyone re-roofing (Building Regs now require dry-fix on new work), landlords wanting to close the maintenance loop on their portfolio, and homeowners on exposed sites where the wind keeps testing the ridge.
When mortar is visibly cracked or missing under ridge tiles, when a ridge tile is loose or has come off, when you're re-roofing, or when you want to convert the ridge as a one-time upgrade at the same time as any other roof work.
BS 5534 (British Standard for roofing) requires mechanical fixings on ridge tiles on all new work since 2015. Cement-bedded ridges fail predictably in 20–25 year cycles. Dry ridge is the definitive fix, done once.
What happens if it's ignored
A roof issue left alone compounds quickly. Water tracks, timber rots, and repair scope escalates by season. Here's what we see when a customer waits.
Once mortar under a ridge fails, water gets under the ridge tile itself, wets the batten and rots the roof timbers along the ridge line. It's a leak that hides, often only visible in the loft.
Cement-bedded ridge tiles are held by their own weight and the mortar. Once mortar cracks, the wind takes them. On coastal properties, this is a life-safety concern as well as a maintenance one.
Roofs need to breathe. Solid mortar ridges block the ridge-line airflow required in modern cold-roof construction, and condensation builds up in the loft, rotting timbers from the underside.
Any re-roof carried out since 2015 that has a cement-bedded ridge does not meet current BS 5534. Increasingly this is being flagged in homebuyer surveys and treated as a defect.
Our process
We measure the ridge length, count the tiles, check the tile profile and confirm ventilation requirements based on the roof build-up.
A written fixed-price quote within 6 hours, kit, tiles, scaffold and any ventilation upgrades priced fixed.
Ridge tiles lifted, old mortar raked out completely, and any damaged ridge tiles set aside for replacement.
Ridge roll (breathable, ventilating) laid over the apex, batten fitted where required, and each ridge tile mechanically fixed with a system-approved screw and clip to BS 5534.
Ridge line checked for straightness and weather-tightness, scaffold down, and the 10-year written workmanship guarantee in writing.
Why homeowners pick us
Every install meets the current British Standard for slating and tiling, the same standard required on all new roofs and re-roofs since 2015.
Mechanically fixed dry ridge components carry a 20+ year manufacturer warranty and real-world service life beyond 50 years, matching or exceeding the tiles below.
Modern dry ridge systems provide continuous ridge-line ventilation as part of the ridge roll, meeting Part F Building Regs and preventing condensation in the loft.
A dry ridge conversion costs about the same as two rounds of mortar re-bedding. After that, it's pure saving, plus no more mid-cycle failures.
Each ridge tile independently fixed to the batten by an approved screw and clip, rated for wind loadings well beyond mortar-only bedding.
A typical semi-detached or detached property is dry-ridged in a single day; longer terraces and complex hip-plus-ridge arrangements in two.
The detail
Dry ridge is a small system in area but a critical one in function. Below is how we approach it across the housing stock of Yorkshire.
The ridge roll is a breathable, corrugated strip that seats over the apex, forms the ventilation gap and shields the ridge tile fixings. We specify Klober, Manthorpe, Cromar or Ubbink systems depending on the tile profile and the ventilation requirement.
Each ridge tile is mechanically fixed to a batten screwed to the roof structure. We use manufacturer-matched screws and clips, torqued to spec, not generic hardware. This is what makes dry ridge wind-uplift compliant.
Modern roofs need airflow to remove moisture from the loft. Where the eaves are already vented, ridge ventilation completes the airflow path. Where the eaves are sealed, ridge ventilation alone can be inadequate, we survey and specify the right combination.
Hipped roofs need matching dry-hip components, a continuous system that also seals and mechanically fixes the hip tiles. We fit dry hip alongside dry ridge as one job, or convert one and leave the other where budget dictates.
On new-build roofs, dry ridge is Building Regs standard. On retrofit conversions, we're replacing a failing mortar bed with a compliant mechanical system, same effect, longer service life. Both processes are similar; the retrofit adds the strip-out phase.
Domestic dry ridge is nearly always on standard pitched roofs, houses, extensions, garages. Commercial dry ridge extends to workshops, church roofs, agricultural buildings and light-industrial pitched roofs, where extended ridge lengths take a continuous system for cost.
FAQ
A typical semi-detached or terraced conversion sits between £550–£950 including scaffold or tower. Detached houses with longer ridge lines are usually £850–£1,600. Fixed price on the quote.
Yes, any re-roof covering more than 25% of the roof triggers BS 5534 compliance, which requires mechanical fixings on ridge tiles. Dry ridge is the standard route to compliance.
Usually yes, if they're structurally sound they lift, get cleaned and re-seat on the dry system with the new mechanical fixings. Cracked or spalling ridge tiles are replaced with matched stock.
Very slightly, the ridge line is a fraction thicker with the roll underneath, and the tile-to-tile joint is dry rather than mortared. From ground level and in matched colour, it reads as a normal ridge.
Yes, the ridge roll is designed to provide the continuous ridge-line ventilation required by current Part F Building Regs. Combined with eaves ventilation, it gives a modern cross-flow airflow path.
Real-world service life is 50+ years. Ridge rolls carry 20-year manufacturer warranties, and the fixings are corrosion-rated for the design life of the roof itself.
Yes, and it's the most efficient way to do both. Same scaffold, same day, one fixed price.
Yes, full 10-year written workmanship guarantee. The manufacturer warranty on the components sits on top of that.
