Services/Slating and tiling/

Slate, and what separates one from another.

Slate is sold as though it were one thing. It is not. Where it was quarried, how thick it is and how it is fixed decide whether the roof lasts thirty years or a hundred, and on this coast the fixing matters as much as the stone.

No call-out charge, and the phone is answered 24 hours.

Slate roofing.

Welsh slate is the benchmark, and the reason so many roofs round here were still watertight at ninety years old. It is dense, it splits thin, and it barely moves. It is also the dearest thing on the list, so it tends to go on houses where matching the original matters more than the invoice does.

Most new slate roofs in Cumbria are Spanish, and there is nothing wrong with that as long as you buy the right grade. The good ones are tested to T1 and S1 — the marks that say the slate will not rust-stain or delaminate — and they will see out fifty or sixty years. The cheap ones are the same colour and a different proposition entirely, and telling them apart on a pallet is most of the job.

Then there is the local stone. Westmorland and Burlington green is thicker, heavier and laid in diminishing courses, largest at the eaves and smallest at the ridge. It is a different trade from hanging a uniform slate, it needs a roof structure that can carry the weight, and it is what makes a Lakeland roof look like a Lakeland roof.

What we fit

  • Welsh slate, where the roof is meant to outlast everybody
  • Spanish slate in tested T1 and S1 grades, never the unmarked stuff
  • Reclaimed slate, sorted and graded to match an existing terrace
  • Westmorland and Burlington green in diminishing courses
  • Copper or aluminium nails, never anything that will rust out
  • Slate hooks where the exposure or the pitch calls for them
  • Head laps set for the pitch and the exposure, not to a default
  • Lead valleys, soakers and abutments in code-appropriate lead

Worth knowing.

Welsh or Spanish?
Welsh if you are matching a good original roof or you want a hundred years. A tested Spanish slate if you want sixty and a sensible price. We will quote both.
Nails or hooks
Hooks are not a shortcut. On an exposed roof or a shallow pitch they hold better than nails and make a future repair far less destructive.
Reclaimed slate
Worth it to match a terrace. Every slate gets checked and sounded first — a reclaimed roof is only as good as the sorting that went into it.
What the sea does
Driven rain on this coast gets under a short head lap. We set laps for where your house actually stands, which is why an exposed roof costs a little more in slate.
