Expert ridge tile replacement and dry-fix ridge conversion across Canterbury and East Kent. Permanent solution — no more mortar failure. Free no-obligation surveys.
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.”

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.

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.
