We are looking for quotes to re-seal a flat roof on our third storey extension. The area is approximately 4.5m by 3.5m. Previous survey completed in February 2010 suggests the overall roofing condition is good, but the severe weather at the beginning of the year has lifted the edges of some of the felt panels allowing water to leak through during heavy rainfall. It was suggested at the time that all we should need is the felt re-sealing, although we are open to the option of simply fitting the felt anew. The roof area is at the rear of a mid-terrace house. Access would be either by ladder from the rear of the house using a neighbours garden (conservatory below won't allow access directly from our garden) or via the front of the house either by scaffold or ladder up and over the front roof which remains sloped/tiled.
