Flat Roofing Cambridge – EPDM – Hills Road
Flat Roofing Cambridge
Cambridge Roofers were asked to carry out a survey and provide recommendations for the refurbishment of a failed asphalt flat roof on Hills road Cambridge. The client had instructed previous contractors to refurbish the roof with a liquid overlay but there was no evidence of this and it had clearly failed.
The client was given a full explanation of their options and decided to recover the roof with a single ply EPDM and 120mm insulation board. Due to the low position of the window sill, a gulley had to be formed to ensure that a minimum 150mm upstand could be maintained.
