Whether you are renovating your old home or designing a new one, there are many different types of roof construction to choose from, including A-frame roofs, butterfly roofs, Gable roofs and M-shaped roofs. But one form of roof construction that is becoming an increasingly popular commercial roofing choice is the flat roof — a design choice reminiscent of Egyptian, Arabian and Persian architecture styles.
A 2018 analysis showed that the UK flat roofing market has been seeing steady growth. While they have traditionally been a popular choice for non-residential buildings for practicality and cost, people are now turning to them to create a cool and modern home — they also have the added advantage that they require fewer materials to cover the same roof span.
While flat roofs do look aesthetically pleasing, there are more practical reasons why a homeowner might opt for flat roofing. Perhaps you can’t get around certain planning permission restrictions with regards to the height of your building. Maybe your neighbours have objections, as a traditional pitched roof might obscure their view or their light. More still might like the idea of having a flat roof so they can convert the space into a balcony or roof garden.
Whatever the case, here at Ploughcroft, we’re fans of flat roofs as they mean lower construction costs for clients, faster installation and more living space. They also provide the option of solar panel installation. Installing solar panels on a flat roof is a great way to reduce your carbon footprint.
Of course, there is a range of flat roof construction methods available. Below, we’ve listed a few you should know about if you’re looking to convert to a flat roof.
Reinforced Bitumen Membranes (RBMs) are two or three layers of waterproof, flexible materials that have been rolled out and bonded together with hot bitumen, resulting in a waterproof membrane.
This flat roof construction method generally requires a protective layer on top of the membrane — commonly gravel or shingle. These materials are bonded to the membrane so that they don’t move. In high winds, this layer provides added protection that holds the membrane down. It also provides protection during the hot summer months or when someone walks on its surface.
A warm flat roof adds extra insulation, resulting in increased thermal efficiency and lower heating bills throughout the year. Warm roofs involve packing insulation into every available void underneath a waterproof membrane to prevent heat from escaping. Warm roof insulation also occurs in pitched roofs.
For large flat roofs, we at Ploughcroft recommend the use of Sika Roof Waterproofing Membranes. This construction material is generally used for the covering of existing flat and pitched roofs. The advantage of using Sika Roof Waterproofing Membranes is that we can apply them without having to remove the existing roof covering. As this method is liquid-applied, it is ideal for complicated roof areas where there is a lot of detail. Liquid roofing is also low maintenance and its application causes minimal disruption. This construction method provides long-lasting elastomeric weatherproof protection, as well as peace of mind.
If your flat roof is relatively small (for example, if you are using a flat roof on your garage or your extension), we recommend opting for the Firestone RubberCover. This environmentally friendly option comes in seamless sheets, and is highly durable and fire-resistant, offering a watertight and long-lasting roofing solution.
