If planning on having a flat roof installed on a private or commercial property, you are likely to come across a range of options, with the actual materials used varying for a variety of reasons, such as the climate or changing seasons and available finances. Get the facts about flat roof materials
Here are two of the most common flat roof materials that are likely to feature:
Built-Up Roof (BUR)
The built-up roof construction typically refers to the hot tar styled flat roof material which was highly popular and seen as the material of choice for installing flat roofs across the country. It was typically found that the BUR roof material was a very cost-effective option for those in need of a brand-new or replacement roof. The installation process typically involved laying down two or three layers of a water resilient material which had a layer of hot tar placed between each layer. Its top and final layer would be finished with a thick layer of pebbles or similar gravel, which was highly effectively at giving a hard-wearing finish.
Even though this flat roof material is the most cost-effective on the market, it is generally found to be very difficult to maintain to a high standard and avoid the onset of puddles pooling on top of the surface. A roof of his type needs to be laid to a professional standard and given ongoing maintenance to make sure it’s able to remain water resilient for the long-term.
Ethylene Propylene Diene Monomer (EPDM)
The ethylene propylene diene monomer is one of the more modern materials for flat roof construction and is manufactured in a highly resilient rubber type material which has the potential to last up to 50 years. The rubber materials in this roofing system are quite similar to the rubber found in most inner tubes. EPDM roofing can be installed in a choice of three different techniques, which typically refers to using a glue or ballasted system or using high-strength fasteners. This material offers ease in the installation process, mostly due to the fact that it is extremely light in weight and also being very pliable.
Maintenance with this roof material is far-sight easier than the alternative of using the hot tar system as the rubber is very easy to patch in the unlikely event that a leak is detected. The EPDM material is generally very dark in colour which soaks up the sunlight and therefore not always recommended for areas that are prone to receiving extended periods of high temperatures.
