Flat roof

A bitumen flat roof, also known as a built-up roof (BUR), is a type of low-slope or flat roofing system that consists of multiple layers of bitumen (a sticky, tar-like substance) and reinforcing materials such as fiberglass or polyester felt. Here are the basic steps involved in the installation of a bitumen flat roof: Roof Preparation: The existing roof surface is cleaned and prepared for the installation of the new roof. This may include the removal of any existing roofing materials, such as shingles or asphalt. Base Layer: A base layer of insulation is installed on the roof deck to provide thermal protection and support for the roofing system. Bitumen Layer: A layer of bitumen is applied to the roof, typically using a hot mop or spray equipment. Reinforcing material, such as fiberglass or polyester felt, is embedded into the bitumen layer to provide additional strength and stability. Repeat Layers: Additional layers of bitumen and reinforcing material are added to the roof to build up the desired thickness and strength. The number of layers will depend on the specific requirements of the roof and the local building codes. Surfacing: A surfacing material, such as gravel or mineral granules, is applied to the top layer of the roof to protect the bitumen and provide additional protection against the elements. It is important to note that the installation of a bitumen flat roof is a complex process that requires specialized knowledge and skill. It is recommended to hire a professional roofing contractor with experience in bitumen roofing to ensure that the job is done properly and safely. Regular maintenance and inspections can help identify issues before they become more significant problems and can extend the life of the roof.
