Bitumenhuovat

Bitumenhuovat, also known as asphalt shingles or bitumen roofing felt, are a common roofing material. They are manufactured from a base material, typically fiberglass or organic felt, which is saturated with bitumen. Bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. The base material is coated on both sides with a weathering asphalt layer, and the top surface is usually covered with mineral granules. These granules provide protection against UV radiation, impact, and contribute to the aesthetic appearance of the roof by offering a variety of colors.

The manufacturing process involves impregnating the felt mat with hot bitumen, followed by coating it with a more durable asphalt layer. Finally, the mineral granules are applied to the upper surface while the asphalt is still warm, and a release material, such as sand, is applied to the underside to prevent sticking. Bitumenhuovat are popular due to their relatively low cost, ease of installation, and good water resistance. They are available in various forms, including single-layer and multi-layer options, which can affect their durability and performance.

The lifespan of bitumenhuovat can vary depending on the quality of the materials, installation, and local climate conditions, typically ranging from 15 to 30 years. They are suitable for a wide range of roof slopes and are a widely used roofing solution in many parts of the world. Maintenance generally involves periodic inspection for damage, such as curling, cracking, or missing granules, and making necessary repairs.
