Flat roofs have had a bad press in the past; often regarded as a poor quality, slapdash alternative to sloping roofs - many consider them to be a quick and cheap solution.

However, more and more, flat roofs have come back into fashion thanks to the latest architectural designs that now allow everything from botanical gardens, solar panels and rooftop patios to be built with a real visual flair and originality.

As well as offering a more stylistic approach to roofing, the everyday home owner can also take advantage of the low maintenance, long-lifespan advantages of the flat roof design. So to get you clued-up on what you need to know, Roofing Supplies has put together a list of some of the most important aspects that make up a great flat roof.

Roofing Membranes

Starting off with one of the central functions of roof building, waterproofing the area is absolutely crucial to get right and there are a number of different membrane choices you can choose from to go about sealing your roof off...but where do you start? Roofing Supplies stock both EPDM and Liquid membranes to make the structure completely watertight.

EPDM (ethylene propylene diene terpolymer), is incredibly durable and long-lasting with a fast install time, making it an extremely efficient way off finishing off your roof. It is also a much more eco-friendly choice than other roofing material options - derived from recycled rubber materials such as tires, making it more environment friendly. You cans see our full range of EPDM products here to get you started.

We also stock a wide range of breather membranes, primers and resins to waterproof everything for your new roofing project as well as paint brushes needed to apply your liquid membrane.


Roof Foundation

The roofing foundation is the basis on which the flat roof is completely supported, therefore it has to be resistant to a range of different loads and conditions and must be made to withstand all the stresses and strains of whatever ends up on top of it. The roof joists, if insulated, must be ventilated to a satisfactory level to avoid problems such as damp - air circulation is also incredibly important and must be considered to prevent a build up of moisture.

Dealing With Run-off

One of the issues with flat roofs is the slight impracticalities when it comes to run off. Rain, snow and everything else that ends up on flat roofs doesn't remove itself as quickly as it would on a sloping roof, therefore falls have to be put into the structure of the roof - either cut to falls, tapered firring or tapered roofing insulation before the deck is laid.
