Ridge tile failure is the most common roofing problem across Chichester's Victorian, Edwardian and interwar housing stock. The original mortar bedding on most pre-war properties has now reached or passed the end of its service life. We re-bed ridges in the appropriate mortar specification for each property type, with mechanical fixings on exposed elevations.

Walk down any Victorian terrace in St Pancras or Whyke and look up at the ridges. On properties where the mortar bedding has not been renewed in the past 20 years, you will typically see cracked mortar, gaps between the ridge tile and the main roof covering, and tiles that are visibly rocking on their beds. These are not cosmetic problems — open ridge mortar allows wind-driven rain directly into the roof space and provides the entry point for the freeze-thaw damage that opens the gaps further each winter.
The correct mortar specification for ridge re-bedding depends on the age of the property and its position. For Victorian and Edwardian properties with clay plain tile roofs — the majority of the heritage stock in St Pancras, Whyke and the city centre — a lime-based mortar is the appropriate specification. Portland cement mortar is too rigid for the differential movement of clay tile roofs and causes edge spalling on the tiles it contacts. For post-war concrete tile roofs, a well-gauged sand and cement mortar at 3:1 is standard. We always specify the mortar to the property, not to the job rate.
On exposed roof elevations in Chichester — south and west-facing ridges, properties in Selsey and East Wittering, and anything above the general roofline of the surrounding buildings — mortar bedding alone is not sufficient for ridges. Wind uplift on a fully mortar-bedded ridge with no mechanical fixing can displace tiles despite visually sound bedding. We specify aluminium ridge clips (dry-fix brackets) as supplementary fixing on all exposed ridges. These clips lock the ridge tile to the batten and prevent uplift without requiring the ridge to be dry-fixed throughout, which can cause movement issues on older roofs.

📞 01243 278085Modern construction typically uses full dry-fix ridge systems — polypropylene ventilated ridges with mechanical clips and no mortar. This system eliminates the maintenance cycle associated with mortar bedding and provides better ventilation of the roof space. For re-roofing work on post-war and modern properties in Chichester, full dry-fix ridge is our standard recommendation. On Victorian and Edwardian properties, mortar bedding with clips is usually more appropriate to the character of the building.
Hip tiles — the tiles running diagonally up the corners of hipped roof sections — fail for the same reason as ridge tiles and are often overlooked because they are less visible from the street. On Chichester's Edwardian semis and detached properties in Stockbridge and Summersdale, hip tile failure is a consistent finding on survey. We re-bed hip tiles to the same specification as ridges, with mechanical clips on exposed positions.
"Ridge had been gradually opening up for years. Full re-bed in lime mortar with clips on the exposed west elevation. Done properly, no shortcuts."
"Three ridge tiles off in the October storm. Emergency repair same day, permanent re-bed completed within the week. Very professional."
"Hip tiles were loose on both corners of the Edwardian semi. Didn't know until the survey. Re-bedded and clipped — no more rattling in the wind."
Ridge problems in Chichester show as loose or slipped ridge tiles and crumbling mortar along the apex — worst on the exposed coastal and peninsula properties.
When it is not the answer: If the underlying covering is sound and the problem is localised, a targeted repair is the honest answer rather than a larger job. Read the full guide.

Wet or high-wind days can pause work at height — we build weather margin into every Chichester booking.
Access is by tower, ladder or scaffold depending on the job and the property; scaffold is always itemised in the written quote. Scaffold is specified for: any job needing safe standing time at height - always itemised in your written quote, never a hidden extra, and we arrange it.
The Georgian streets inside the city walls — The Pallants, the Cathedral Close, Little London — mean tight access and permit-controlled pavement space, with conservation constraints on visible scaffold. Pavement scaffold and skip permits go through Chichester District Council; allow a few working days on streets like The Pallants, North Pallant, Little London where space is tight.

Worked example: A rear valley rebuild on a 1930s Summersdale semi: around £680 including tower access and waste removal.
No deposit on repairs under £500. You never pay before the work is done and inspected. Re-roofing over £5,000 is staged — nothing up front before materials are on site. Reduced 5% VAT usually applies to re-roofs; confirmed in writing.
Covering PO18, PO19, PO20 and surrounding postcodes.
Workmanship is covered for 10 years in writing, with manufacturer warranties on any materials on top.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
We keep disruption to a minimum, protect the area below the work, and clear everything before we leave. You do not need to stay home for external work - we just need power and access agreed in advance.
Most work runs year-round; temporary weatherproofing goes on the same day if rain interrupts. Chichester's coastal-plain position brings salt-laden south-westerlies and harbour humidity that slow drying times.
Visible cracked or missing mortar between the ridge tile and the main tile covering, ridge tiles that visibly rock when pressed (if you can safely access them), and damp patches on the ceiling directly below the ridge line are all indicators. After a storm, displaced ridge tiles are sometimes visible from the pavement. We include ridge condition in all survey visits.
Re-bedding on a standard semi-detached in Chichester costs £600 to £1,400 for a full ridge run, depending on length and access. Per-metre rates of £40 to £70 apply for shorter sections. Hip tile re-bedding is £400 to £900 depending on length. Written quotes after a free survey.
The mortar specification depends on the property. Lime mortar for Victorian and Edwardian clay tile roofs; well-gauged sand and cement for post-war concrete tile roofs. We never use undiluted Portland cement on a clay tile property — it causes tile edge damage and is too rigid for the movement characteristics of clay construction.
On exposed elevations — south and west-facing ridges, coastal and exposed positions — yes. Mortar bedding alone can fail under extreme wind uplift even when the mortar is sound. We specify aluminium ridge clips as supplementary fixing on all exposed ridges as standard.
A properly bedded ridge with mechanical clips in the right mortar specification should last 20 to 30 years. A dry-fix system on a post-war property should last the life of the roof. Mortar bedding without clips on an exposed Chichester roof might last 10 to 15 years before the next re-bed is needed.
For a two-storey property, yes — scaffold is required for safe access and to allow the mortar work to be done properly. For single-storey garage or outbuilding ridges, a ladder and roof ladder can be sufficient. We confirm access requirements in the quote.
Mortar work should not be carried out in frost conditions. We avoid ridge repointing in cold snaps from November to March on exposed sites. In practice, Chichester has relatively mild winters and dry working days are often available. We advise on timing at the quote stage and schedule work around weather forecasts.
Ridge repointing is weather-dependent. Mortar work should not be carried out in frost conditions — mortar applied in sub-zero temperatures fails to cure correctly and will deteriorate rapidly. We avoid ridge repointing in cold snaps from November to March on exposed sites. In practice, Chichester's mild maritime winters mean dry working days are available for much of the year, and we schedule around weather forecasts to ensure the correct conditions. We also avoid working in high winds — ridge tile placement requires conditions where the tile can be positioned accurately and the mortar can be pointed without wind interference. We confirm programme timing at the quote stage and adjust to conditions as needed. The alternative — carrying out mortar work in the wrong conditions to meet a date — is something we never do.
