Types of Residential and Commercial Flat Roofing Systems

To the inexperienced eye, most flat roofing systems look exactly alike. However, the knowledgeable Edmonton roofers at A. Clark Roofing & Siding LP are well aware that many forms of flat roofing exist, and we will personally ensure we install the best roofing system according to your property’s functional and climatic requirements. Here are a few different types of common flat roofing systems.

Built Up Roofing System (BUR)

Currently, the most common type of flat roofing system, Built Up Roofs are most popularly referred to as “tar and gravel roofs” (although tar is no longer used due to its carcinogenic properties).

In reality, these roofing systems consist of asphalt, glass fiber or mineral surfaced cap sheets, and aggregate (such as gravel). Multiple layers of cap sheet and asphalt are built up for water-and-weather-proofing purposes, and the whole roof is then covered with gravel to reflect the sun’s rays away in order to control temperature. This system’s simplicity and cost-effectiveness, combined with its effectiveness, all contribute to its current popularity.

Single-Ply Membrane System

Single-Ply Membrane Roofing Systems consist of manufactured sheets of either thermoset (EPDM) or thermoplastic TPO or PVC).

There are many benefits to either of these materials. For instance, EPDM is well-known in the industry for being highly dependable, as well as cost-efficient, due to its low maintenance requirements, low installation labour costs, and generally long warranties; while TPO and PVC offer a wide range of versatility because they can be repeatedly softened and hardened, which make repairs simple and affordable.

Modified Bitumen System

Sometimes referred to as “rubber roofs”, these polymer-modified roof membranes are typically manufactured into rolls and applied in layers to your rooftop, and often finished with aggregate, mineral, metal foil-laminate, or smooth liquid-applied surfacing.

These types of roofing systems are very durable, weather resistant, flexible, as well as easy to repair and install, ensuring quality control.
