Slate Roofs across Greater London

Slate is common on London's older terraces, where Victorian and Edwardian builders used it for its thin profile, modest weight and resistance to water. Many of those roofs still carry their original slates and nails, and the usual sign of age is nail fatigue: slates slipping out of position one after another as the old fixings corrode. When that happens across a whole roof, re-slating is usually better value than chasing individual repairs. Ashlar Roofing renews slate roofs in natural slate and fibre-cement slate, and carries out repairs to existing slate roofs.

Natural slate from Wales or Spain is split from quarried stone and, when well chosen and well fixed, can last well over a century. Welsh slate is valued for its density and colour, while Spanish slate offers a natural finish at a lower cost. Fibre-cement slates are made to a uniform size and thickness, which keeps the price down and makes them quick to lay. We fix slates with copper or stainless nails, or slate hooks where appropriate, at the head lap your roof's pitch and exposure require, and sound original slates can be reused where that suits the job.
