 A flat roof describes a horizontal or gently sloping roof surface. Flat roofs are commonly found on commercial and industrial buildings but can also be installed on residential properties too. They can be built with a variety of different materials, including asphalt, tar and gravel, single-ply membranes, metal, and concrete. Because flat roofs don’t have an angle to them that means they often require additional measures to help with drainage, to stop water from pooling on the roof.
Advantages
Cost-effective: Flat roofs are generally cheaper to install than pitched roofs, as they require less expensive materials and take less time to build.
Multi-use: Flat roofs offer a practical surface to use as a garden and for solar panels.
Easy access: Flat roofs are quick and simple to access and maintain.
Contemporary styling: Flat roofs look clean and minimal, they are much more modern than a pitched roof.
Energy-efficient: Flat roofs can be designed to provide better insulation, which leads to reduced energy consumption.
Drawbacks
Drainage: Flat roofs are prone to drainage issues, because water is not directed away from their surface. Standing water can then lead to leaks.
Reduced durability: Flat roofs typically have a shorter lifespan than that of pitched roofs.
Vandalism: Flat roofs can be easy to access, therefore measures must be taken to prevent criminals from gaining access to flat Roofing.
Regular maintenance: Flat roofs require regular maintenance and inspection to ensure they remain in good condition.
Insulating Flat Roofing
Flat roof foam insulation (SPF) is a very effective method of insulating and waterproofing flat roofs. Flat roof foam insulation involves spraying a layer of polyurethane foam directly onto the roof surface, which then expands to create a seamless layer of insulation which prevents leaks and helps to protect roofing from harmful UV rays.
Flat roof foam insulation can also help to prevent air leakage and moisture infiltration, which could otherwise cause mold to build up. When installed correctly, flat foam roof insulation can last for many years with only a minimal level of maintenance required, and because insulation is made from recyclable materials, and due to the fact that it reduces energy consumption, flat roof foam insulation can help to cut carbon emissions.
