Slate re-roofing in Crickhowell

Slate on almost everything, on old rubble-stone walls, with stone-slate and older coverings on some of the farmhouses in the valley. A slate roof in Crickhowell that has lasted this long has not failed; its nails and battens have. Re-slating puts the same covering back on new fixings, and we put you in touch with a Crickhowell roofer who does it properly.

Re-slating a Crickhowell roof

Grading the originals

Every slate comes off and is tapped. Sound Welsh slate is re-laid on the front elevation; delaminated slate goes. On a typical older Crickhowell house a third to a half comes back.

Matching the new

New Welsh slate matches the originals and is what the conservation officer expects where there is one. Spanish slate is the cheaper option on the back or on a house outside the constraints, and the roofer should show you both.

Fixings and coursing

Copper or stainless nails, battens gauged to each course, and the diminishing coursing kept where the roof has it.

Exposure in Crickhowell

The valley is sheltered compared with Brecon but the Black Mountains and the Sugar Loaf catch the rain, and the town floods from the Usk in a bad winter. BS 5534 sets the headlap and fixings by exposure, and Crickhowell sits in a demanding category, so ask the roofer what they have specified.

Slate and the planning position

Inside Bannau Brycheiniog National Park with a conservation area covering the centre, so natural slate and traditional detailing are expected.
