What Is Bitumen Roofing?
What is bitumen roofing? It’s a type of asphalt roofing that’s a mixture of bitumen and a synthetic polymer called Atactic Polypropylene. During application, it creates a strong bond with the asphalt and the base support layer. It’s typically applied through torch-down methods and provides a tougher membrane. SBS, or synthetic rubber, is also added to the bitumen to improve energy efficiency. It’s also highly reflective, reducing heat absorption and stress on the HVAC system. roofing supplies
Modified bitumen is an asphalt-based roofing system that originated in the 1960s. Because of its weather-resistant nature and low-maintenance, it is an excellent choice for flat roofs. It’s available in two basic varieties: single-ply and multiple-ply. The application method depends on the type of bitumen, but most of them are installed in two layers. You can install it hot or cold, but be aware that it doesn’t tolerate excessive heat.
Modified bitumen membranes use polymers to make them more durable and tough. This type of membrane is suited for cold-weather installations, as it eliminates the need for heat sources during installation. The material is also highly energy-efficient and tear-resistant. Its flexibility allows it to withstand stresses and is incredibly waterproof. A bitumen roof can last for many years. If your roof has a leaking problem, you may be able to repair it with a bitumen patch.
Modified bitumen is available in a variety of colors and textures, as the granules in the cap sheets are compatible with the color of your shingles. Modified bitumen comes in rolled sheets that are up to 36 feet long. These sheets are placed over the base sheet membrane. Modified bitumen can also be applied to damaged roofs with minimal effort. Modified bitumen is eco-friendly, as it can be recycled.
Modified bitumen is the most affordable of the three types of asphalt roofing. It’s the easiest to install, as the material is typically installed in 33-foot long rolls. The roll is nailed at regular intervals along its length. Each course should overlap the previous one by four inches. Each course should then be sealed with roofing cement. Modified bitumen can last for up to 15 years, which is an excellent lifespan for an asphalt roofing system.
Modified bitumen roofing is a type of asphalt roofing that’s made for flat and sloped roofs. It’s also a great choice if you’re looking for a low-maintenance option for a new home or an existing structure. Because it’s eco-friendly and recyclable, it’s one of the most eco-friendly options available. But if you don’t know what bitumen is, you’ll need to consult a roofing professional.
Modified bitumen roofing is often used on flat, low-slope commercial roofs. It can be installed in two layers, or as a multi-ply system. It first appeared in the commercial roofing industry during the 1960s in Europe. Previously, most commercial structures used a built-up roofing system consisting of alternating layers of asphalt and fabric. Afterwards, bitumen was widely used as a roofing material.
