HOME ABOUT ROOFING CONSTRUCTION OUR PROJECTS SECTORS CONTACT US Drainage M&J Group (Construction & Roofing)Drainage Drainage All roofing works will connect up to the ground drainage system, either through internal downpipes or external guttering and downpipes. The flow of rainwater to the below ground drainage is always a crucial part of any roofing and cladding project, and as such needs to be carefully considered. Quite often clients believe they have a roof problem, when in fact it is their drainage (or lack of) that is causing their water ingress. M&J can provide full drainage surveys to assess the drainage condition of all buildings, and even provide rainwater attenuation waterproofing systems that reduce the rainwater run off at roof level, reducing the impact on the local drainage network.
