Triple layer bitumen felt system
Time: 9 weeks
This Grade 2 listed building in the centre of Blackburn had been neglected for a number of years and was suffering from large scale water ingress.
The roof had previously been overlaid, however these had been unsuccessful. Following an extensive intrusive survey, a new triple layer bitumen felt system was specified with a 25mm insulation board, due to height restrictions. This was backed up by a 20 year single point warranty.
