A flat roof is an almost level roof consisting of a horizontal base installed to the joints of the ceiling. This base is covered with a waterproof membrane. Despite the name, most flat roofs do have a slight pitch to help water drain away easier. The standard pitch of the flat roof is never greater than 10-15° to the horizontal. This type of roof is often installed on small outbuildings, extensions, garages or carports.
One of the biggest reasons why flat roofs are gaining popularity is due to their affordability. These roofs keep the cost of building projects down. As a result, many property owners across the UK have added a conservatory's or an additional room to the upper floor, and with a flat roof has proven to be much less expensive than a pitched roof extension. And aside from awkward installation, the repair process of pitched roof extensions makes them more expensive than flat roofs.
Modified bitumen is a relatively cost-effective flat roofing material due to its short lifespan of 10-20 years. It is reasonably durable and can withstand extreme temperature changes. Apart from that, it can reduce the heat flow on flat roof surfaces.
