In his presentation, “It’s Not a Cover-Up!” Roofing 2.0: What You Need to Know about Modern Commercial Roofing Applications, Richard provides an overview of:
Overall, roofs share the same basic elements, including slope, step flashing, available materials suitable for a particular type of project, and the basic need for shelter.
One of the most important factors is how a roofing system works with a building to achieve the project’s overall specifications and goals. Conventional roofing systems are changing, and thanks to advances in technology, they are safer, easier to install and last longer.
Richard walks us through the top two commercial roofing systems in use today: built-up and single-ply roofing.
Asphaltic and bitumen systems have performed well, despite few technological updates for more than 100 years. Built-up systems require at least two to four layers. Modified bitumen can offer many installation options. Richard warns us of the drawbacks to these systems:
Single-ply roofing is an inexpensive alternative to built-up systems. Single-ply also comes in two types, thermoset and thermoplastic. They have been engineered for easier and quicker application, have a higher puncture resistance, are easier to tape seams, and more. Some types of single-ply can be applied when it’s as cold as -6 °C, compared to other systems which require higher temperatures for installation. This means that for crews that tent to apply to roofs, they can lengthen their roofing season. Single-ply systems also offer the greatest variety of membrane and installation options.
The single-ply system today owns 80% of the market, and Richard believes this number will continue to grow for many reasons, including:
Watch the video to learn more about how these two systems compare, to gain a more technical understanding of the single-ply roofing systems, installation and trends.
