Modified Bitumen Roofing

Modified Bitumen Is An Ideal Choice For Flat or low-sloped Roofs

Protect Your Flat Roof Year-Round

Modified bitumen roofs are designed to handle temperature fluctuations, heavy rain, and UV exposure. Its multi-layered construction prevents cracking and punctures, ensuring long-lasting protection for flat roof systems.

Keep Your Roof Leak-Free

One of the key benefits of modified bitumen roofing is its seamless waterproofing. Its self-adhering or heat-welded application creates a watertight seal that prevents leaks and pooling, which are common issues with flat roofs.

When and Where to Use Modified Bitumen Roofing

Roofs of essential buildings

For buildings that need to stay open and operational at all times, BUR is a solution that has been used for over 100 years. The redundant applications allow for increased protection against damage and leaks.

Roofs that need extra reliability

APP is a redundant asphaltic system without the odor and labor required for hot mopping. APP is often used in smaller commercial roofing jobs, especially in urban areas.

Roofs that need more flexible application methods

For roofs requiring the reliability of asphalt with more flexible application methods, SBS roofs are an excellent choice. SBS can be applied in a variety of other ways including hot-mopped, cold-applied or self-adhered.

Buildings that require certification

For buildings that require ENERGY Star® or LEED® certification, utilize an EnergyCap™ sheet with any BUR, APP, and SBS system. This is ideal for projects requiring asphalt roofing reliability along with Energy Star® LEED® certified solutions.
