KM Roofing Edinburgh, Roofers Edinburgh, an example of a blocked downpipe on a property in South Edinburgh. It does not take long for water to start to damage the exterior fabric of the building. The downpipes will need to be cleared and checked for fractures in the cast iron. Unfortunately this issue has been left undetected at the rear of the building for a long period of time and is now causing dampness in the stone work and damaging the lime mortar pointing. This highlights the need for regular roof checks and roof maintenance. KM Roofing Edinburgh are members of the National Federation of Roofing Contractors- NFRC and Flat Roofing Alliance (FRA).
