About this deal

Most flat roofing problems can be solved proactively – just make sure you use a professional and experienced roofer to install your roof, use the most suitable materials for your building, and ensure regular inspection and maintenance are undertaken to prevent any small issues from becoming much bigger problems. A flat roof is never truly flat. It must be designed to include a fall to allow water to be evacuated effectively from the roof. Building regulations suggest a minimum fall of 1:40 for a flat roof. Different waterproofing finishes will require a different flat roof fall. For example sheet metal materials can be laid with a fall of between 1:60 and 1:80. It is best to consult wit the manufacturer of the waterproofing solution chosen to ensure the correct fall is designed into the flat roof. Cut the blistered material up to the point that it is attached tightly to the roof still. Step two: Apply new membrane material Single-layer torch-applied overlay membrane specificallyfor refurbishment projects to lengthen the operationallifespan of the existing waterproofing.

Within our bitumen membrane waterproofing systems we have the following EPD certificates for our membranes and PIR insulation:Flat roof technology has come a long way since the 60s and 70s. Thanks to modern materials and stylish glazing, today’s flat roofs are the epitome of architectural style. Some are even being used in new and unusual ways, from sun terraces and balconies to green roofs for budding urban gardeners. Have you heard of the ‘urban heat island’ effect? Green roofing reduces the impact of the summer heatwaves forecast to be an increasing problem in the future. The fact they are a great natural insulator will save money and reduce energy costs. Green roofs and roof terraces must be specifically designed to carry the additional loads that they will receive. As you can use System 15 on practically any existing roof membrane, it means you won’t have to replace any roof structures. That’s perfect for commercial properties as it means the business can carry on as usual. How to apply Acrypol System 15:

The sound-reducing properties of a green roof means they are chosen to provide more peace and quiet. Not only do they provide protection from noisy aircraft/traffic, but also heavy rainfall or hail, which can cause problems on a flat roof. Taking on a flat roof construction, repair, overlay or replacement? It's critical that you choose the best flat roof material. Read on to understand the different types of flat roof covering, their advantages, and the various installation methods availableWhen considering the best flat roof material, your priorities and budget will factor considerably in your decision. Hopefully, the various flat roof covering options outlined above will give you a clearer idea of what you need for your project. The most common flat roof joist sizes tend to be 150 x 50mm, 175 x 50mm and 200 x 50mm. The spacing will depend on the span and loads, but usually we can see flat roof joist spacing between 400mm and 600mm centres.

Compared to pitched roofing, flat roofs do not drain very well. As such, they commonly develop ponding water – defined as water that stands in a puddle on a roof for 48 hours or more. The flat roof can be given a fall by the structure by laying the joists at a slope using supporting tapered beams. This will create a slope in the roof both externally and internally. If you’re a business owner and need a large-scale solution for your industrial property, Acrypol 15 is perfect for the job. Like Acrypol System 10, it’s fast and easy to install, but it also comes with added features that make it even more long-lasting.

Limit access to your roof unless it’s been designed to take regular footfall. If you need to walk on it, use temporary boards Try to do your flat roof inspection after a period of rain. This will help you spot any areas of ponding (big puddles) and highlight any drainage issues.
