Built-Up Roofing Systems and Single-Ply Membranes Compared

Choosing the right roofing system for your commercial property is incredibly important. The type of building and the demands of your local climate are two major factors that will determine what type of roofing system would best serve your needs. In this article, Northern Pacific Roofing, the leading roofing contractor in our local area, compares built-up roofing systems to single-ply roofing membranes.

Built-Up Roofing Systems

Built-up roofing systems are made up of three to five laminated layers, hot tar, roofing felt, a layer of bitumen and an aggregate top layer. Built-up roofing systems are reliable, which is why they have been used for over a century. A commercial built-up roof can last for up to 40 years as long as it was properly installed and maintained. 

Built-up roofs also require very little maintenance after installation. They can reflect UV rays away from your building, improving energy efficiency. However, built-up roofs are complicated to install and add significant weight to the building structure. As a commercial roofing expert, we can help you determine if a built up roof is the right choice for your building.

Single-Ply Membrane Pros and Cons

Single-ply membrane roofing systems were developed more recently than built-up roofing systems. There are two types: thermoset membranes and thermoplastic membranes. Single-ply roofing systems are highly reflective, helping improve the building’s energy efficiency. They can be installed quickly and they allow you your choice of insulation. A single-ply membrane roof has seams, however, and it does not have a hard top layer to protect it.
