Winchester properties span 250 years of architectural history. The tile type on your roof defines the maintenance requirements, the repair costs and the conservation area compliance.
Clay plain tiles are the original roofing material on virtually all Winchester Victorian, Edwardian and 1930s properties. Low-profile, nibbed (hooked over battens as well as nailed), typically reddish-brown or terracotta in colour, approximately 265×165mm. They are manufactured from natural clay fired in a kiln — the material has been used in Hampshire since the medieval period.
Correctly maintained clay plain tiles last 80–150+ years. The tiles themselves are typically not the failure point on Winchester period properties — the lead flashings, ridge mortar and felt underlay fail first. Original clay tiles from the 1920s–30s are still performing on hundreds of Winchester properties.
Where found in Winchester: Weeke, Chandler's Ford, Oliver's Battery, Hyde, Fulflood, St Giles Hill, St Cross and all Winchester's interwar and earlier suburbs.
Repair cost: individual clay tile replacement with reclaimed match: £150–£400 including access and sourcing.
Conservation area note: clay plain tiles are required for any re-roofing work in Winchester's conservation areas where the original material is clay plain tile. Concrete alternatives are not compliant.
Concrete interlocking tiles were introduced to UK housebuilding in the 1950s as a faster, cheaper alternative to clay plain tiles. Larger format (typically 380×230mm or 420×330mm), with interlocking side edges that reduce the number of tiles required per square metre and speed installation.
Most of Winchester's post-war housing stock (Stanmore, Winnall, Harestock, Badger Farm, Boyatt Wood in Eastleigh) carries concrete interlocking tiles from the original build — now 50–70 years old.
Design life: 30–50 years. The tiles themselves often outlast this; the iron fixing nails corrode significantly earlier, causing nail sickness.
Repair cost: matching concrete tiles are readily available and low cost. Individual replacement: £150–£350. Nail sickness clip repair: £400–£900 for a full elevation.
Natural Welsh Penrhyn or Ffestiniog slate is found on higher-specification Victorian and Edwardian Winchester properties — the larger detached and semi-detached villas on St Giles Hill, some Hyde properties, and properties built to a higher specification than the standard terrace. Grey, thin (typically 5–8mm), cleaves cleanly and has an extremely long lifespan.
Design life: 80–150+ years for Welsh quarry slate. Original Victorian slate is still performing on Winchester properties after 130 years. Spanish slate (introduced in the 1980s) has a significantly shorter lifespan of 30–50 years.
Repair cost: reclaimed Welsh slate for matching: £150–£600 depending on sourcing and access. A full re-roof in natural Welsh slate: £12,000–£20,000+ on a larger property.
A modern alternative designed to approximate the appearance of clay plain tiles. Slightly thicker than original clay, often with a textured or coloured surface intended to age similarly. Used on some 1980s–90s Winchester re-roofs where clay was specified but concrete was substituted.
Design life: 35–50 years. Surface pigmentation fades more than genuine clay. On Winchester conservation area properties, concrete plain tiles may not satisfy like-for-like requirements.
Available from manufacturers including Marley and Cedral. Designed to replicate the appearance of natural Welsh or Cumbrian slate. Lighter than natural slate, easier to install, consistent dimensions. Used on some Winchester re-roofs where budget or access constraints prevent natural slate specification.
Design life: 40–60 years. Manufacturers typically offer 30–40 year warranties. Not appropriate for Winchester conservation area or listed building work requiring natural slate.
The correct tile for any Winchester re-roof is: for pre-1945 properties — the original tile type (clay plain for most; Welsh slate where original); for post-war properties — concrete interlocking in a profile matching the existing; for conservation areas — confirmed with Winchester City Council before ordering. We survey and specify the correct material for each Winchester property. Free survey — call 01962 809171.
The most common repair specification challenge in Winchester is matching an existing tile for a small repair or section replacement. Clay plain tiles vary by manufacturing era, kiln temperature, clay source and weathering — a 1920s Chandler's Ford semi will have a specific colour range and surface texture that differs from even a close modern equivalent. We bring tile samples to survey and confirm the match before ordering.
For concrete interlocking tiles, the challenge is profile rather than colour. There are dozens of discontinued profiles from the 1960s–80s that are no longer manufactured. Many are available reclaimed through Hampshire builders' merchants and roofing material reclamation specialists. We carry stock of the most common Winchester post-war estate profiles — Redland 49, Marley Modern, Russell Grampian and others — and can source the less common profiles on a 5–10 working day lead time.
The practical advice: if you have a repair that requires tile matching on a Winchester property, call us before assuming the tiles cannot be matched. In most cases they can, with the right sourcing network. Free survey and tile matching confirmation — call 01962 809171.
We carry out free surveys and provide written condition reports across Winchester and all surrounding Hampshire areas. NFRC registered, fully insured, 10-year written guarantee on all work. Same-week appointments available. No call-out fee on any survey or daytime visit.

Clay plain tiles on pre-1945 properties and concrete interlocking tiles on post-war estate properties. Winchester's housing stock spans both eras across different areas of the city.
30–50 years for the tile surface. The iron fixing nails fail before the tiles in most cases — nail sickness emerges after 40–50 years on most Winchester post-war estates.
Yes — where the property is not in a conservation area, material choice for re-roofing is at your discretion. Clay tiles are more expensive but last significantly longer. In Winchester conservation areas, the original material must be retained.
Spanish Pizarra slate has a higher water absorption rate (0.6% vs 0.1–0.3% for Welsh) and a lifespan of 30–50 years rather than 80–150. It is not appropriate for Winchester conservation area or listed building work.
Clay plain tiles are low-profile, relatively thin, typically reddish-brown. Concrete interlocking are thicker with interlocking side edges. Natural slate is grey and thin. We confirm tile type at the free survey visit if you are unsure.
No call-out fee. No obligation. Written condition report.
