Minnesota Roofing Options: 3 Types of Commercial Roofs
The commercial roofing system is critical to protecting the entire building, and with Minnesota's weather patterns, you need something durable and long-lasting.
Narrowing down your options starts with understanding the three types of commercial roofing systems available, and our expert team has a breakdown of what they offer below.
Metal Systems
With building design trends in today's construction, more individuals need dynamic options with high durability, and metal offers both. A commercial metal roof can last up to 50 years or longer with the right care.
Metal performs the best on pitched roofs that exceed 3:12 or if you're looking to install over existing materials like shingles because they can accommodate uneven spaces.
Some of the most popular brands are McElroy, EDCO, Custom Bilt Metals, and MBCI Metal Roofing. They are an energy-efficient and eco-friendly choice and come in several different types of systems available, with the most common ones being:
- Standing Seam: Raised seam system that runs vertically from the roof and is attached to the decking with hidden fasteners and clips.
- Corrugated: This design is ribbed or wavy and is durable, lightweight, and inexpensive.
- R-Panel: This is multi-ribbed roofing with exposed fasteners that are easy to install.
Metal Roofing Cons
One of the most inherent characteristics of metal roofs is oil canning, which can be difficult to define and measure. Essentially, it's when a standing seam gets overstressed and can't hold a flat form, which can create visible waves in the roofing system. Scratching and scuffing, as well as corrosion, are another concern; however, both of these can be mitigated with a specialized protective coat.
Metal is also prone to being louder than other materials in rainstorms, but this can be mitigated with proper insulation. For some, the cost can be an initial issue. However, the materials last longer than traditional alternatives, and pay for themselves in increased value and fewer replacements.
BUR
BUR, or built-up roofing systems, started in the 1800s and are made of multiple layers of surface materials, including bitumen material and ply sheets with alternating layers of asphalt and fabric. Once the covering is completed, a final layer of gravel is laid on the surface. This option works well for low slopes and flat roofs and has a strong seal for continuous protection from UV rays.
This style works great for low-sloped and flat roofing designs that need to handle foot traffic and require good weather and fire resistance. A few of the best built-up roofing manufacturers are Barrett Company, GAF Materials Corporation, Henry Company, and CertainTeed, all of which deliver exceptional and durable finishes.
BUR Drawbacks
When working with BUR roofing systems, blisters, waves, cracks, and open joints are the biggest concerns. These most often occur from weather, inadequate or incorrect installation, or projectiles hitting them. In a best-case scenario, you'll have a highly efficient protective coating, but regular inspections can help reduce some of the risk of larger damage.
Hazardous fumes can be released while the roof is being installed, making it less eco-friendly, and BUR roofing is more expensive than other flat roofing options like TPO or PVC.
TPO
TPO, or thermoplastic polyolefin, is one of the most popular roofing systems for low-slope and flat roofs. With the correct maintenance, it can last up to 30 years. Its performance and durability make it a great value. TPO is designed to resist long-term heat and UV rays.
While EPDM is another affordable and flexible option, it is not as resistant to the elements and damages more easily. TPO is puncture-resistant, more durable, and has higher energy efficiency properties, making it an efficient and money-saving option. A few popular brand names are GAF, Elevate TPO, and GENFLEX; each one delivers high-quality results depending on your needs.
TPO Drawbacks
One of the biggest concerns with TPO roofing or seam failures is when two sheets of membranes don't join together properly or come apart. They can also be at risk of punctures and tears, ponding water, UV damage, and weathering. In most cases, keeping up with regular maintenance, repairs, and inspecting the material can prove valuable in preventing structural damage.
TPO also comes at a higher cost than similar roofing materials and is best installed if you have a roof with a steepness below 2:12 on low slope and flat roofing systems.
