Slate re-roofing in Machynlleth
Welsh slate re-roofing in Machynlleth: original slate graded and re-laid, new slate matched. One local roofer, a written quote, free to use.
This is slate country: the town and the valley around it were roofed from the Corris and Aberllefenni quarries a few miles up the road, and most roofs here are still natural slate on old timbers. A slate roof in Machynlleth 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 Machynlleth roofer who does it properly.
Re-slating a Machynlleth 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 Machynlleth 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 Machynlleth
The Dyfi valley opens straight onto Cardigan Bay, so the town gets Atlantic weather first: driving rain, salt in the wind and some of the highest rainfall in Wales. BS 5534 sets the headlap and fixings by exposure, and Machynlleth sits in a demanding category, so ask the roofer what they have specified.
Slate and the planning position
Machynlleth sits just outside the Eryri (Snowdonia) National Park boundary, but much of the surrounding countryside is inside it, where the park authority expects natural slate on any visible roof.

Slate re-roofing in Machynlleth: common questions
What does slate re-roofing cost in Machynlleth?
MyJobQuote's 2026 guide gives Welsh natural slate at £100 to £150 a square metre installed and Spanish at £70 to £93. Re-laying your own sound slate brings the material cost down. The Machynlleth roofer prices the actual roof after looking at it.
Must I use Welsh slate in Machynlleth?
Machynlleth sits just outside the Eryri (Snowdonia) National Park boundary, but much of the surrounding countryside is inside it, where the park authority expects natural slate on any visible roof. Outside those constraints it is your choice, and many roofers lay Welsh on the front and Spanish on the back.
