Why Choose KJ Roofing & Building for Flat Roofing?
Flat Roofs On Wrexham Extensions, Garages And Outbuildings
Across Wrexham, flat roofs usually turn up where a house has been extended or a garage, porch or outbuilding has been added. That means a lot of different ages and builds, from older rear extensions on village properties in Gresford and Coedpoeth to newer additions on the housing developments around Acton.
An older flat roof often needs a proper look at the deck, edges and outlets before deciding whether a repair is enough or a full renewal makes more sense. Where the building next to it is a period property, we keep the finished roof tidy and in keeping with the rest of the house.
