Flat roofing is an affordable, easy to maintain and adaptable roof style of choice for those drawn to the appeal of a minimalist design aesthetic or the convenience of a cheaper, more manageable roof covering. However, the most important aspect of installing a flat roof is ensuring that it's properly sealed to prevent damp, moisture ingress and more serious problems such as leaks and water damage.
Although waterproofing must never be overlooked - no matter what type of roof covering you're considering - the upward-facing flat roof surface is particularly susceptible to the harsh, and often relentless exposure of rain, wind and sun damage. You may also have to contend with the more extreme headline-grabbing weather events that are increasingly becoming the norm across Britain. Therefore, preventing structural and visual damage, as well as extending the lifespan of your flat roof, are vital factors to consider in maintaining and protecting it against frequent and costly repairs.
Luckily, there are a multitude of flat roof waterproofing products out there that are designed to seal, fix, reinforce and even rapidly absorb water in the event of urgent maintenance work. Whether you're looking to coat asphalt, bitumen, concrete, brickwork, slate, metal or plastic roof materials in your domestic or industrial project, we've got everything you need to make your next flat roof waterproofing project simple, seamless and as straightforward as possible.
