R.S.M Roofing are specialists when it comes to flat roofing systems in Bristol. We offer all the latest options and types of flat roof covering for flat roof construction, repair or replacement.
We’ll make sure your flat-roofed garage, home extension, porch, shed or summerhouse looks smart and stays watertight with an efficient warm deck or cold deck roof installation, depending on your preference and thermal insulation requirements.
A cold roof has insulation tucked in between the roof deck rafters, so cold will inevitably seep through the unprotected wooden rafters into the space below. A warm deck roof has a thick layer of insulation installed on top of the roof deck itself, meaning the entire roof structure is insulated before the covering is applied, making it more thermally efficient.
The traditional and most common favourite flat roofing material of felt blow-torched on with bitumen (tar) remains an affordable, robust solution for waterproofing a flat roof, which we often use when our clients request it.
Alternative flat-roofing materials are:
Whatever you use to cover your flat roof it will only perform its best if the underlying flat roof structure is sound and in good repair.
When we install a new flat roof we provide a strong structural deck made of plywood, timber board or oriented strand board of appropriate thickness. The roof deck must have a slope (minimum 1:80 according to building regulations) to allow rainfall runoff so water doesn’t pool on the surface.
Once insulated and covered in waterproof flat roofing materials the deck should not need replacing for decades, and can be recovered as and when necessary.
If you’re confused about which type of flat-roofing would best suit your budget, the purpose of your building and the structure itself our experts will be happy to explain all the options and advise you which flat roof covering would be right for your requirements.
We are qualified and competent to undertake any and all installation and repair work related to pitched or flat roofing, including guttering and leadwork.
