19 Mar What materials are used in flat roofing?
Flat roofing requires a different approach to regular roofing. This is because flat roofing has a tougher job getting rid of moisture, which over time can cause corrosion.
Flat roofing has actually advanced significantly over the past fifty years and the materials used in flat roofing are so good that they can have a 25-year guarantee, a level of guarantee that was unheard of just ten years ago.
At Roundhay Roofing, we don’t choose the materials used in flat roofing. Our customers do – based on the invaluable information we give them about each option. A lot of the decision-making process with regard to flat roofing involves budgeting, because roofing can be notoriously expensive, depending on the materials used. We have worked on flat roofs for garages and outbuildings, dormers and extensions. Our aim is to provide you with a flat roof that best suits your needs, and a flat roof that’ll perform adequately throughout its life.
We use one of two materials in the creation of flat roofing:
1. Torch-on felt roofing
Felt roofing is waterproof and highly resilient to the elements. Most flat roofs will have felt on them. When roofing a flat roof, at least 3 layers of felt are needed one with a solar reflective property. The process of installing felt roofing is a dangerous one, due to the nature of how it is sealed onto the roof. However, we are highly experienced with torch-on felt roofing and we’d be happy to come round to your property to see how we can help you.
2. Topseal GRP
Topseal GRP is the latest innovation in flat roofing. It’s a proven way of waterproofing a flat roof. It’s basically a certified range of liquid-applied fiberglass flat roofing that dries quickly into a solid, and then provides complete protection from the weather. It’s great for garages, offices and factories because it’s extremely durable – more so than felt. However, this is not a product DIYers’ can master so it’s worth getting a professional to install it for you.
Other materials that are used in flat roofing around the world include asphalt, Ethylene propylene diene monomer rubber (EPDM), Turbo Seal, Modified Bitumen, cold-applied liquid membranes, PVC vinyl and flexible thermos-polyolefin (FTPO). The material a lot of people will be familiar with because of films like The Shawshank Redemption, is coal-tar – this material is actually a carcinogen and is not recommended by us at all. However once it is dry, the carcinogen affects it can have are largely minimised.
Do you need new flat roofing?
If your garage, outbuilding, extension or other flat-roofed building is leaking water, you will likely need a new flat roof laying. At Roundhay Roofing we have over 30 years of experience working on flat roofing and can offer our Topseal GRP service with a 25-year guarantee.
