KM Roofing Edinburgh, Roofers Edinburgh – fitting a replacement Velux window unit. The new window unit our roofers fitted is supplied with a white uPvc finish as it is for a bathroom, to help prevent mildew and staining from condensation & aid ease of cleaning. Our roofers stripped out the clay roof tiles, removed the old Velux window unit & flashing kit and fitted the new window with correct flashing kit for the roof pitch. The roof was then tiled back in around the new Velux window. All roofing work by KM Roofing Edinburgh. KM Roofing Edinburgh are members of the National Federation of Roofing Contractors- NFRC and Flat Roofing Alliance (FRA).
