Flat roof Brighton
Mineral roof felt is a type of roofing material commonly used on low-slope or flat roofs. It is made of a combination of bitumen (a sticky, tar-like substance), reinforcing materials such as fiberglass or polyester felt, and mineral granules. Here are the basic steps involved in the installation of a mineral roof felt: Roof Deck 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. Felt Layer: A layer of felt is installed onto the insulation, typically using a hot mop or torch. The felt is carefully laid out and cut to size before being secured to the roof deck. Mineral Granules: A layer of mineral granules is applied to the top layer of the felt to provide additional protection against the elements. The granules are typically embedded into a layer of hot asphalt that is applied to the felt. Repeat Layers: Additional layers of felt and granules 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 more mineral granules, is applied to the top layer of the roof to protect the felt and provide additional protection against the elements. It is important to note that the installation of a mineral roof felt is a complex process that requires specialized knowledge and skill. It is recommended to hire a professional roofing contractor with experience in mineral 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.
