As the name implies, flat roofs are a flat surface roof construction, very distinct from the slanted roof. Flat roofs are constructed using various building materials, which often dictate the structure you get. Making an informed decision concerning the flat roof type you want is easier if you are familiar with the many available styles. Depending on the cost-effectiveness and availability of materials, you can decide what kind of commercial flat roof you require. Here are details of the different flat roof varieties.
Rubber EPDM Flat Roofs
Rubber is a typical component of flat roof construction. The rubber membrane is installed on the roof using thin sheet construction materials. Dense stones weigh the sheet down for stability. Sometimes the constructors may prefer bonding the rubber membrane or binding it. The polymer and rubber material achieve the flexibility and elasticity of this type of roof. The rubber type of flat roof construction can respond to temperature changes and impact thanks to its elasticity. Compared to other flat roofs, rubber installations are lighter and more robust.
Spray Foam Flat Roofs
Spray foam flat roof installation entails coating the roof surface with high-density polyurethane. A waterproofing coat is sprayed over the foam. The top coat boosts the roof's longevity by assisting in the reduction of water retention. Spray foam installation is quick and very affordable. This type of installation is easy to recognize because the foam patterns can be visible when the coat wears off.
BUR flat roofs are common and have been existential for a long time. These flat roof types entail the use of tar and gravel. Gravel serves as ballast and is sandwiched between the tar and plywood sheets. The gravel layers make the roof very durable and able to withstand extreme weather conditions. The major drawback is that the roof structure presents a challenge when it comes to replacement, as removing it isn't easy.
Altered Bitumen Roofs
Bitumen flat roofs are constructed using asphalt. Rolls of asphalt are mounted on the roof's surface in two layers which include the base sheet and the top sheet. It is relatively easy for you to mount the asphalt layers as there are self-adhering materials that do not require torching. Bitumen roofs have a light color and reflect solar radiation, saving HVAC costs.
Understanding the different kinds of commercial flat roofs is crucial so you can choose one that best suits your needs. It is advisable to consult a commercial roofing expert to gain a thorough grasp of the flat roof type you select and whether it will meet your needs.
