Expert ridge tile replacement and dry-fix ridge conversion across Canterbury and East Kent. Permanent solution — no more mortar failure. Free no-obligation surveys.
Most Canterbury roof problems show up as a damp patch, a dislodged tile visible from the street, or grit from the roof in the gutters. Here is how to tell a repair from something bigger.
When it is not the answer: If more than about a third of the covering has failed — widespread nail sickness across a whole slope — repairing tile-by-tile is money wasted. Read the full guide.
We trace the leak to its real source — often a metre up-slope of the internal stain — rather than patching the symptom.
A fixed price with the cause, the fix and any access clearly listed. No call-out fee.
Non-urgent repairs booked within a few days; genuine leaks made weathertight same-day.
The failed element is renewed in matched materials and the surrounding area checked.
Debris cleared, work shown to you, and the repair guaranteed in writing.
| Job | Typical duration |
|---|---|
| Slipped or cracked tiles | 1–2 hours |
| Lead flashing renewal | Half a day |
| Rear valley rebuild | 2–3 days |
| Chimney flashing | Half to one day |
Wet or high-wind days pause tiling; we build weather margin into every booking and make leaks safe first.
Most Canterbury repairs run from a tower or roof ladder; scaffold is quoted only where the job needs safe standing time at height. Scaffold is specified for: chimney-side repairs, full valley rebuilds and anything beyond a day at height - always itemised in your written quote, never a hidden extra, and we arrange it.
Canterbury’s medieval core and the Victorian terraces off Wincheap and St Dunstan’s often mean tight frontages, shared rear access and conservation-street constraints, so scaffold and skip placement take planning. Pavement scaffold and skip permits go through Canterbury City Council; allow a few working days on streets like Palace Street, Burgate, St Dunstan’s Street where space is tight.
Dry-fix conversion · Mortar re-bed · 30-year product guarantee
Canterbury's damp Stour valley climate is particularly hard on traditional mortar-bedded ridge tiles. The above-average winter moisture and repeated freeze-thaw cycles crack cement bedding faster than in drier inland locations — typically every 10–15 years on exposed Canterbury roofs, compared to 20+ years in sheltered inland conditions. The result is that ridge mortar failure is one of the most common roofing repairs across the city, on housing stock from the Victorian terraces of St Dunstan's to the 1970s semis of Barton and Rough Common.
We strongly recommend dry-fix mechanical ridge conversion over mortar re-bedding as a permanent solution. Modern dry-fix systems use polypropylene clips and a flexible EPDM bedding strip that accommodates the thermal movement Canterbury roofs experience through the seasons. The ridge tiles are mechanically secured, the system is fully breathable, and the 30-year product guarantee means you will not need to revisit the ridge in your lifetime.
Cracked or missing mortar beds on Victorian and Edwardian terraces in Wincheap, St Dunstan's and the Old Dover Road corridor, where the original lime-bedded ridges were later re-pointed in cement. Shifted ridge tiles on 1960s–70s concrete tile estates in Barton and Rough Common where the original mortar specification was minimal. Full mortar blow-out on exposed north-facing ridges after severe frost events. Ridge tiles displaced by wind on elevated Harbledown properties.
“Ridge had been re-pointed twice by other companies and kept cracking. Canterbury Roofing converted the whole ridge to dry-fix. Permanent solution, no more mortar, 30-year guarantee on the system. Should have done this years ago.”
“Ridge tiles on our 1960s semi had shifted on three sections. Full dry-fix conversion in a day. Properly done, good clear explanation of what they were fitting.”
“Partial ridge repair on our Victorian terrace — only one section had failed. They repaired the affected section rather than pushing us to replace everything. Honest approach.”

Worked example: Three slipped tiles and a loose ridge section on a 1930s semi in Hales Place: about £280 in a single visit.
No deposit on repairs under £500. Nothing paid before materials are on site. Itemised VAT invoice on completion.
Covering CT1, CT2, CT3, CT4 and surrounding postcodes.
Workmanship on the repaired section is covered for 10 years in writing; any replacement tiles carry their manufacturer warranties on top.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Usually a day of ladder or tower work and a little tile debris — we sheet below the work area and clear before we leave. You do not need to stay home for external work - we just need power and access agreed in advance.
Repairs run year-round; temporary weatherproofing goes on the same day if rain stops work. The Stour valley holds humidity, so drying times lengthen in autumn and moss returns fast on north-facing and tree-shaded roofs.
A full ridge re-bed on a standard 3-bed semi in Canterbury — stripping the old mortar-bedded ridge and installing a mechanically fixed dry-fix system — typically costs £600–£1,200. Traditional mortar re-bed on smaller sections runs £200–£500. Dry-fix ridge conversion is the recommended permanent solution as it eliminates future mortar failure. Free no-obligation quotes on all work.
A dry-fix ridge system secures ridge tiles with mechanical clips and a flexible bedding strip rather than traditional mortar. In Canterbury's damp valley climate, standard cement mortar beds crack as moisture freezes and expands in winter, requiring re-pointing every 10–15 years. Dry-fix systems are fully weathertight, allow thermal movement without cracking, and carry a 30-year product guarantee. We recommend dry-fix on all Canterbury re-ridge work.
Signs include visible cracking or missing sections of mortar around the ridge base, ridge tiles that rock slightly when pushed from ladder height, ridge tiles that have shifted position, recurring leaks at the ceiling top-floor junction, or debris from crumbling mortar in the gutters. Nail sickness ridges can also cause tiles to move out of line. Any of these warrant a free survey.
Traditional mortar bedding should not be carried out in freezing temperatures as the mortar will fail before it cures. Dry-fix ridge conversion can be carried out at any time of year and is the preferred option for winter work. We advise on the right method for the time of year when surveying.
Both. If only a section of ridge has failed we carry out a targeted repair. If the entire ridge is mortar-bedded and cracking, a full dry-fix conversion makes more long-term sense. We give an honest assessment and cost comparison on the free survey.
