A Cornwall-based roofing specialist has carried out a tricky contract this week, which required the closure of one of the UK's busiest motorways. 7858 JR Flat Roofing, based in Redruth, secured a contract with a longstanding client, Moto Hospitality, the UK's biggest provider of motorway service areas. The company worked from scaffolding which was specially designed to sit on a truck, in order for it to be situated on the motorway lane. The footbridge over the busy M1 required some repairs and the contractor was brought in to carry out the work. But to ensure safety for the site staff, the motorway had to be closed to traffic temporarily.
