ALT Re-roofing of St. Andrew's in Ufford, Cambridgeshire with Collyweston slate (c) James Brennan Associates Collyweston stone slate is a traditional roofing material local to Northamptonshire, Cambridgeshire, Lincolnshire and Rutland. Collyweston Slate is not a true slate, but is actually a lime stone and roof tiles were traditionally created from it by leaving the stone slabs to go through a cycle of freezing and thawing over several winters that would reveal layers that could be broken into flat slates.
ALT Wooden crates of Collyweston Slate for re-roofing of St. Andrew's (c) James Brennan Associates Due to #climatechange the natural conditions for the freeze-thaw cycle needed to break down the stone slabs into slates no longer exist. Thankfully, heritage building specialists Messenger Construction, following a research and trial process with English Heritage and Sheffield Hallam University were able to revive this traditional process using large commercial freezers.
