Property owners and developers require commercial roofs that deliver three things — energy efficiency, cost-effectiveness, and longevity. In the commercial roofing sector, those factors add up to a trifecta of benefits.
Unfortunately, business leaders outside the commercial roofing trades too often get bogged down in the wide-reaching differences between the styles and materials. But by understanding the fundamentals aspects of a commercial roofing system, owners and investors can make informed decisions and enjoy the benefits they deserve. The experienced professionals at Davidoff Roofing in London, Ontario, hope this information proves useful.
Common Types of Commercial Roofing Systems
There is no one-type-fits-all solution to maximizing the advantages of an outstanding roof system. The materials for a roof in one region may not necessarily serve the interest of owners and commercial tenants in another. The best commercial roofs are those that seamlessly match regional conditions, budgetary concerns, and long-term goals. These are benefits commonly enjoyed from the following materials and commercial roofs.
Metal Roofing
As a commercial roofing system, metal provides cost-effective retrofitting benefits. This material extends the life of existing commercial roofs by sidestepping the cost of complete replacements. Metal roofs have enjoyed widespread popularity in recent years due to design improvements, colour options, and increased longevity.
Thermoset Roof Membrane
This material ranks among the most preferred systems in areas that require enhanced protection from severe weather. Its ability to withstand hail and high winds makes it an excellent deterrent to damage and sometimes expensive repairs. Commercial roofs made from thermoset roof membranes also enjoy energy efficiency because the material resists heat.
Thermoplastic Roof Membrane
Typically used in low-sloping commercial roofs, this type employs reinforced sheet materials that may be welded together for enhanced energy efficiency and water resistance. Also called Thermoplastic Polyolefin or simply TPO, the sheets are comprised of polypropylene and ethylene-propylene rubber and may be selected in a variety of colours.
Built-Up Roofing Membrane
This commercial roofing system has already passed the test of time after more than 100 years. Built-up roofing membrane installations are typically comprised of 3-5 layers that deftly handle wide-reaching temperature and climate conditions. Sometimes referred to as BUR by industry insiders, it can outpace other systems in terms of longevity.
Modified Bitumen Roofing
This complex commercial roofing system employs a combination of asphalt and polymer materials to create flexible layers that can be installed in a variety of ways. The commercial roofs may involve sheets, hot asphalt, or adhesives applied through heat or cold methods. One of the unique benefits this system offers property owners and developers is that it can be installed year-round.
Green Roofing Systems
Property owners and developers who want to leverage sustainable building materials and designs have embraced green roofing systems. These commercial roofs employ layers and different materials that include vapour controls, waterproof membranes, decking, and others to construct commercial roofs that allow grass and other plant life to grow. After securing a multi-layer build, green roofs maximize rainwater usage and account for drainage. These commercial roofing systems replace much of the flora that once grew where commercial buildings now stand.
The Longevity of Commercial Roofs
When property owners and investors consider the best commercial roofing system for their needs, longevity ranks among the most important factors. How long your commercial roof lasts will likely be determined by matching the materials and design to weather conditions and temperature shifts. When commercial roofing materials are deployed under the right conditions, property owners can generally anticipate the following lifespans:
- Metal Roofing: 40-60 years
- Thermoset Roof Membrane: 20-30 years
- Thermoplastic Roof Membrane: 20 years or longer
- Built-Up Roofing Membrane: 15-20 years
- Modified Bitumen Roofing: 10-20 years
- Green Roofing Systems: 30-50 years
These estimates are generally based on selecting roofing materials and designs that benefit the building while accounting for local factors. To maximize its lifespan, decision-makers would be well-served to consult with a commercial roofing specialist.
