Given how fundamentally important roofing is in keeping us safe, sheltered and comfortable, it stands to reason that there are a lot of questions asked about roofing projects, in terms of repairs, replacements and extensions.

As well as providing high-quality installation, flat roof specialists are also ideal experts to ask any questions you may have about flat roofing, but here are just some of the most frequently asked enquiries.

Are Flat Roofs More Energy Efficient?

Given the increases in energy prices, many people are looking at ways they can make their homes more energy-efficient and reduce their power and heating bills.

With that in mind, flat roofs are generally more energy-efficient than sloped and pitched roofs, although to what extent can depend on the age of the roof, the materials used and the insulation. Flat roofs inherently had a smaller surface area and so allow for less heat loss.

Does A Flat Roof Allow For Water Runoff?

Yes. One of the most interesting facts about flat roof designs is that they are not truly flat. Approved Document H of the building regulations requires a slight incline (typically a ratio of 1:80) to stop water from building up and causing damage.

Is Standing Water On A Flat Roof A Cause For Concern?

Not necessarily, depending on the design of the flat roof. Some flat roofs intentionally hold water as a cooling mechanism, and when a flat roof has a low incline, it can sometimes appear as if there is standing water when it is slowly draining.

For an adequately constructed and effectively waterproofed roof, standing water is not necessarily a concern, and typically this excess water will either drain away, can be swept off or will simply evaporate when the weather improves.

However, larger pools and sags can sometimes be an indicator of more fundamental issues with a roof and it is always worth asking an expert if you have any concerns.
