If you have decided on a flat roof for the extension, using rubber rather than felt offers better value for money. Traditional felt is hardy and if installed properly will last for a good few years, yet rubber is installed in a single exercise, and with no joints or seams, the surface is completely waterproof.
Step 1: Removing the old roof – This might be fibreglass or felt, and the roofing is removed down to the timber sheeting, and with a top rated roofing company in Stoke-On-Trent only a call away, the experts are ready to install a new rubber roof.
Step 2: New Plywood Base is fitted, along with insulation – This is the foundation of the roof, and it will not get wet, as there are sealant coatings to prevent dampness coming through. Once a solid platform has been built, the base is ready for the adhesive.
Step 3: Water Based Adhesive is Applied to the Plywood – An even coat is spread onto which the rubber sheeting will be fixed. The special grade rubber is designed to handle the harsh British climate, and will not be affected by either rain or direct sunlight.
Step 4: Rubber Membrane is Fitted – The rubber sheet is carefully laid, along with attractive edging that ensures a total waterproof seal that will last for many years. Rubber roofs are guaranteed to be leak proof for 20 years, while the roof can have a life expectancy of 50 years or more.
Of course, with a new build, the first step of the process is not necessary, and once the roof is installed, it can be walked on.
