Best Built-Up Roofing (BUR) System Installation Guide

Built-up roofing membrane (BUR) roofs are composed of multiple layers of tar and gravel that form a strong and durable surface. Each layer consists of a different material, which includes bitumen, fabric, adhesive or alternating layers. A BUR roof is easy to repair, but its lifespan is limited to about 20 years. Nevertheless, the upfront cost of a BUR roof is very affordable.

It is important to install the roofing system correctly and in accordance with the manufacturer’s instructions. In general, built-up roofing membrane must be installed parallel to the slope and the cap sheet surface should be installed near-parallel to the slope. This will allow water to shed properly from exposed edges of the cap sheet. It is important to use roofing cement during the application process. This will prevent cracking and minimize the risk of water damage to the built-up roofing system membrane.

Built-up roofing systems should be installed according to manufacturer guidelines and warranty requirements. In particular, BUR should not be installed in adverse weather, such as during the rainy season, when ambient temperatures are too cold or too hot. Moreover, BUR should be applied on a dry and clean deck surface. This will prolong its life and provide a long-term warranty. And when you choose this material, you can be confident that you’ll have a roof that will be resistant to the elements.

Built-up roofing membrane is typically used on low-sloped commercial roofs. It consists of several layers of asphalt and ply sheets. These layers are then typically covered with stone aggregate to add additional protection and aesthetic appeal. This material has a long history of success and is considered the gold standard of flat roofing. However, advances in science and technology have improved it immensely.

Built-up roofing membrane is a flexible type of roofing that can be customized to fit the specifications of your building. It is ideal for low-slope roofs and can be tailored to suit your durability and cost requirements. In addition to its durability, this type of roofing is extremely affordable. With proper design, BUR can help you save on energy costs, too!

BUR roofs offer excellent protection against the elements such as fire, UV rays, and water penetration. Moreover, they feature multiple layers of insulation. Even if one layer is compromised, the system will still keep the building dry. This roof material is a durable and practical option, which pays for itself in the long run with its low maintenance costs.

BUR roofs should be installed in a manner that minimizes water penetration. This material must be properly installed and flashed to avoid leakage. Flashings should extend approximately 100 mm above the membrane, and they must be anchored in accordance with the manufacturer’s instructions. To finish the roof, you need to apply asphalt at a rate of 60 pounds per square foot. Then, you should add a layer of Type IV fiberglass felt to the surface.

When it comes to laying BUR roofs, you should pay attention to the amount of water and bitumen that may leak. If not, you may end up with a ruined finish. If this happens, contact the manufacturer of your roofing membrane to get advice and instructions on cleaning. In addition, you should make sure that you remove excess materials, tools, and wrappings from the installed roofing.

A built-up roof membrane should be installed before applying flood-coating and major roof accessories. Lastly, you need to make sure the built-up membrane is installed properly. You should also consider its edge treatment and set-on accessories. Finally, you should follow the manufacturer’s recommendations and coordinate with other sections of your roof. This will avoid any delays or omissions of related work.

A licensed and certified roof installer is necessary to properly install a built-up roofing membrane. A licensed and certified installer should follow the manufacturer’s requirements and have completed at least two projects with their approved roofing systems for at least 10 years. You should also be aware of the installer’s credentials and insurance.

Whether a contractor uses a BUR or modified bituminous roofing membrane, he or she must follow certain regulations. For example, the roofing membrane must meet the Fire Department’s requirements for external fire resistance. It must also have a permit for storing fuel.
