In this article, we discuss some of the key differences between different roofing membranes, helping you decide which roofing membranes might be the best fit for your project.

Five Considerations When Selecting Roofing Membranes

Accurate roof specification is critical to the performance, lifespan and maintenance requirements of the whole building. Understanding the factors that can optimise roof specifications, aligned to the specific requirements and objectives of the project, can deliver cost and sustainability benefits.

Understanding Roof Specifications

Waterproofing a roof with felt involves using a roofing system where a layer of bituminous felt, often saturated with bitumen or asphalt, acts as a protective barrier against water infiltration. This type of roofing system, commonly known as a built-up roof (BUR) or modified bitumen roof, is ideal for flat or low-slope roofs.

By preventing water damage, felt membrane waterproofing contributes to the overall health and longevity of your building. Whether you're a homeowner, a construction professional, or a government authority, understanding the benefits of felt membrane waterproofing can help you make informed decisions about protecting your property.

In this blog post, we'll delve into the specifics of felt membrane waterproofing, focusing on the innovative SURE-MELT® bituminous system by CARLISLE®. We'll explore how this robust and versatile system can provide long-lasting protection for your roof, from flat roofs to green roofs.
