Roofers in Northamptonshire

Roofing in Northamptonshire

Northamptonshire sits on a band of ironstone and Jurassic limestone, and that geology still dictates what the older roofs are made of. Villages across the north and east of the county carry Collyweston stone slate, quarried and frost-split just over the Welland from Stamford, laid in diminishing courses and pegged rather than nailed. It is genuinely rare, genuinely valuable, and a shocking amount of it has been lost over the years to owners who were told it was cheaper to strip and tile. If a roofer offers to take your Collyweston away as part of the job, get a second opinion first.

The towns tell a different story. Northampton, Kettering, Wellingborough, Rushden and Desborough all expanded rapidly on boots and shoes in the late nineteenth century, leaving dense grids of terraces roofed in Welsh slate at shallow pitch. Corby is later and quite distinct, built out for the steelworks from the 1930s with a large Scottish workforce and expanded again in the post-war decades, so its stock is mostly interwar and 1950s housing carrying its first or second generation of concrete tiles. Much of the county sits on Lias and Oxford clay, which shrinks in dry summers, and the resulting seasonal movement shows up as cracked haunching and leaning stacks well before it shows in the walls.

Chimneys deserve particular attention here, since terraces with shared stacks and open flues are everywhere and abandoned flues left uncapped are a persistent damp source. Of the 119 roofers listed across Northamptonshire, roughly one in four names roof repairs as a core service, so smaller remedial jobs are well covered.
