Natural slate is the premium roof covering — a properly laid Welsh or Spanish slate roof can last 150+ years. We supply and install natural slate for new roofs and re-slating projects, source reclaimed Welsh slate for period property repairs, and work with reconstituted slate where budget or planning constraints apply.
Northwood has a significant stock of Victorian and Edwardian properties originally roofed in Welsh slate. After 100-120 years, even the best slate begins to delaminate. We source reclaimed Welsh slate from demolition projects across the UK to provide the closest visual and dimensional match for repair work.
Welsh slate (now quarried at Penrhyn and Cwt-y-Bugail) is the finest natural roofing slate in the world — dense, consistent, and virtually imperishable. Spanish slate is more affordable but varies in quality. Reconstituted slate (fibre-cement) gives the appearance at a fraction of the cost but lasts 30-40 years versus 100+.
If your Northwood property is in a conservation area, replacement slate must match the original in size, colour, texture and source where possible. We work with conservation officers to agree specifications before work begins, avoiding costly re-work.

Hillingdon's roofing character is defined by the Metroland era. When the Metropolitan Railway reached Uxbridge in 1904, developers transformed farmland into the semi-detached suburban landscape that defines Ruislip, Eastcote, Ickenham and Northwood today. The houses built between 1920 and 1939 share common roofing characteristics — hipped roofs with plain concrete tiles, multiple valleys at hip junctions, and chimney stacks that are now approaching a century of weather exposure.
Hillingdon sits at Greater London's western edge where the urban heat island weakens and rural weather patterns take over. Ground frosts start earlier in autumn and persist longer in spring than in central boroughs — an extra 15-20 frost days per year that accelerates mortar deterioration and tile surface damage. The Colne Valley channels cold air across Uxbridge and the northern suburbs, creating frost pockets where ice can persist in shaded valleys and gutters for days.
Northwood and Eastcote properties command premium prices driven partly by their generous plots and period character. A complete re-roof on a large detached Northwood property can cost £15,000-25,000, but the alternative — visible deterioration reducing kerb appeal in an area where buyers expect immaculate presentation — costs more in the long run.
Every job follows our standard quality process: free inspection and assessment, written quote with full scope of work, professional installation by our own team using specified materials, post-completion inspection with photographic record, and a written guarantee. This process applies to every job regardless of size — a £200 repair gets the same professional approach as a £15,000 re-roof.
