Roofing in the Rhymney Valley
K Williams Roofing works the full length of the Rhymney Valley — from Caerphilly and Ystrad Mynach at the bottom, through Bargoed and the mid-valley towns, up to Rhymney and Pontlottyn at the head. Pitched roofs, flat roofs, industrial roofing and emergency callouts, with the same free written quote wherever the job is.

The whole valley, one local team
The Rhymney Valley runs about 20 miles from the Heads of the Valleys down to the M4. We cover all of it — Caerphilly, Bedwas, Llanbradach, Ystrad Mynach, Hengoed, Bargoed, Aberbargoed, Gilfach, New Tredegar, Pontlottyn, Rhymney and the villages in between. Whether you are on a Victorian terrace in Bargoed or a post-war estate in Caerphilly, the roofs and the weather here are ones we know well.
Industrial and commercial roofing across the Rhymney Valley
The valley has a long industrial history and plenty of working units — the estates at Pontygwindy, Bedwas House, Woodfieldside and Rhymney all have commercial roofs we maintain and repair. We handle profiled metal sheeting, built-up felt and single-ply flat systems, gutter lining, over-roofing and planned maintenance for factories, warehouses and agricultural buildings, with fixed-price quotes and out-of-hours work where production cannot stop.
Pitched-roof housing stock
Most homes in the valley are on natural slate or concrete tile, much of it original. The common jobs are slipped slates after a gale off the tops, cracked ridge and verge mortar, failed chimney flashing and tired felt on rear extensions. We repair where a repair makes sense and re-roof properly when it does not.
