Slate Roofs


Natural Slate is one of the oldest roof coverings throughout history, and it's still being specified today.

This is testament to its sleek, smooth appearance and proven track record in keeping buildings secure and dry.

Even today, we are stripping off slate roofs that are 150 years old, and the slate itself is re-usable and strong enough to last another 50 years at least.

It's stunning good looks and tough finish are a winning formula that compliment buildings of all types whether old or new.

Each new roof is laid onto a solid 50mm x 25mm graded tanalised timber batten which will resist any moisture in the atmosphere, and in the worst case, any water ingress during the life of the roof.

The slates are fixed with non-ferrous fixings such as copper nails or aluminum-alloy nails that are designed to last many decades before perishing and weakening.

The old slate roofs we come across nowadays are usually failing because the nails used in the old days were not non-ferrous, which means they rot and eventually break. The timber battens are usually untreated timber and these weaken too.

This is what causes most slate roofs to fail -not the slate itself.

Laying slates, especially around detail areas such as valleys, chimneys and roof windows, is best left to the experts. It's not a case of putting a couple of nails in and hoping for the best, a good slater will spend just as long preparing and sorting his slates into different thicknesses and grades as he does fixing them onto the roof.

Special tools and practices are used when cutting and fitting around detail to ensure the slate isn't weakened and that it's going to stay put for the lifespan of the roof.

Slate Roofs, when professionally installed by enthusiastic fitters (who love nothing more than to stand back at the end of each roof and admire their own work), WILL 100% make your property look amazing.

It compliments all types of building, brick, stone, metal, timber cladded and compliments any building colour.

Add that to the fact that you will most likely never need to have this roof replaced again, it's worth doing it properly the first time.

We guarantee our slate roofs for 15 years, although we estimate that the roof should last in excess of 50 years if correctly fitted with the best materials.
  • Do you have a roof that has a lot of detail going on? Steps, parapet walls, rooflights, pipe penetrations?
  • Can you see your new roof from anywhere else?
  • A window, your garden or drive?
  • Can your neighbours see it?
We all want our houses to look as amazing as possible and you will not be disappointed with the stunning good looks of your shiny new slate roof.

We have been fitting these slate roofs since 1999 and we still always look for improvements in the fitting process every year as technology advances.

Since 1999 we have created a fitting process that is as perfect as it possibly can be.

It's not all plain slating though. Here's some things to look out for:

Watch out for cheap slates

Some Spanish and Chinese slates do not carry the CE / EN 12326 standards: A1-S1-T1 accreditation. This measures the Absorption, Carbon content and Thermal cycle resistance of the slate. This means that the slate could absorb more water than is recommended, when this water freezes and expands, it damages the slate by causing the outer layer to delaminate over a period of bad weather, seriously diminishing it's lifespan.

Cheap slates can also carry a high carbonate content and have shiny minerals embedded into it. Larger mineral deposits can rust when on the roof, in some cases, holes have developed in the slate due to the sheer size of the mineral content.

Discoloration on cheaper slates is also common, the roof will end up looking like a patchwork quilt when some slates discolour and fade.

Poor workmanship or lack of preparation

If your slater does not sort through the slates before putting them on the roof, you will end up with different thickness slates being laid next to each other giving a very uneven roof surface with gaps under most slates.
They should be graded into thick, medium and thin slates and laid together in their sorts.

Twisted and buckled slates should also be taken out of the piles and cut up for bottom or top courses.

Other specialist slates such as Welsh Tonnie, Swithland, Burlington, Cornish, Collyweston slates are usually classed as heritage roof coverings and these will be graded differently to a standard house slate.

Slate roofs are very time consuming to lay and the material cost per square metre can be high when compared to a man made slate or tile.

A bigger outlay is then required with a slate roof, but the stunning appearance of the building means it's a very wise investment.

Stace Roofing has been successfully slating since 1997.
