Walk from Richmond Market Place down to the Swale and you will see Welsh slate, heavy stone slates and red clay pantiles within a few streets, so there is no single right answer for a roof here. The better choice depends on what your house was built to carry, how exposed it is, and whether the planners have a say. Here is how the two compare for homes in and around Richmond.
Richmond's older properties tell you a lot about what works locally. Georgian and Victorian houses around Newbiggin, Frenchgate and the Market Place are mostly Welsh slate or local sandstone slates laid in diminishing courses. Cottages and outbuildings towards Brompton on Swale, Skeeby and Catterick Village often carry clay pantiles, which are traditional across the Vale of Mowbray.
Post-war and newer estates are different again. Most were built with concrete interlocking tiles, and the roof timbers were sized for that weight. Knowing which group your home falls into is the starting point, because it shapes both what will look right and what the structure can take.
Richmond sits on the edge of the Dales, so roofs here get wind-driven rain from the west and more frost than the lower ground towards Northallerton. Both materials cope well if they are fixed properly, but they behave differently over time.
Pitch matters too. Natural slate generally needs around 22 to 25 degrees or steeper depending on slate size and overlap, while traditional pantiles want about 30 degrees or more. Some modern interlocking tiles are rated down to about 15 degrees, which can make them the only sensible option on a shallow extension roof.
Slate costs more, mainly because of labour. Each slate is sorted, holed and fixed individually, whereas large interlocking tiles cover a roof far faster. As a rough guide for a typical three bedroom semi around Richmond, a full re-roof in concrete tiles might fall somewhere between £6,000 and £9,000, with natural slate more often between £9,000 and £15,000. Clay pantiles usually sit in between.
Those figures depend heavily on roof size and shape, the number of valleys, hips and chimneys, scaffold access on tight streets, and the condition of the timbers once the old covering is off. If your existing slates are sound and only the fixings have failed, reusing them with new battens and membrane can bring a slate roof much closer to tile prices.
Much of central Richmond is a conservation area with many listed buildings, and the Yorkshire Dales National Park begins just to the west. On a listed building you will need consent to change the roof covering, and you will normally be expected to replace like for like. In the conservation area, swapping slate for concrete tiles can also need permission, so check with North Yorkshire Council before ordering anything.
Building control applies wherever you live. Re-covering more than half of a roof normally needs sign-off and can trigger an insulation upgrade. Moving from slate to a heavier concrete tile also means the rafters and purlins should be checked first.
If your home was built with slate, stay with slate where the budget allows. It suits the structure, keeps the character of the street and will usually outlast a tile roof by decades. If it was built with concrete tiles, a like for like tile replacement is usually the sensible, economical choice, and the timbers are already sized for it.
For pantiled cottages, new or reclaimed clay pantiles are worth the extra over concrete copies. Whichever you pick, the quality of the fixing, the battens and the leadwork will decide how long the roof really lasts.
Often yes, but not always. Listed buildings and many properties in the Richmond conservation area will need consent from North Yorkshire Council, and the roof timbers should be checked because concrete tiles are heavier than slate.
The best Spanish slate is a sound, long lasting product at a lower price, but quality varies far more between quarries and grades. Ask which grade is being quoted and expect a shorter life than top Welsh slate.
Frequently they can. On many Richmond roofs it is the nails and battens that have failed rather than the slate, so sound slates can be stripped, sorted and relaid, with reclaimed ones making up the shortfall.
