If you’re sitting in your windowless office wondering what the weather is like outside, it may be time to assess the health of your commercial roofing system. Choosing a new roof can be a daunting task, as there are many factors to consider, such as the longevity of the roof, typical weather variations, and energy efficiency.
In this article, we’ll explore the seven most common commercial roof types and the environments they are best suited for. Whether you’re a property owner, architect, or business owner in the hospitality or restaurant industry, understanding the pros and cons of each option can help you make an informed decision for your building.
Durability, Energy Efficiency and Cost
When it comes to purchasing a new commercial roof, durability, energy efficiency, and cost are the three most important factors to consider. A well-installed and maintained commercial roof system can last anywhere from a decade to over 50 years. However, climate and sub-roof conditions can greatly affect the lifespan of the roof.
Energy efficiency is an essential consideration for business owners since it can save a significant amount of money in the long run. Many cities have added energy efficiency parameters to their permit process, making it a buzzword for years.
The overall cost of a new or replacement roofing system is also a crucial factor to consider. While some systems may cost less to install, it is essential to ensure that durability and efficiency are not compromised to save a few pennies upfront.
In summary, when selecting a commercial roofing system, it is important to weigh the durability, energy efficiency, and cost of the system to make an informed decision that meets your specific needs.
Commercial Roof Types
1. Metal Roofing
Metal roofing is a popular commercial roof type due to its durability and long lifespan of 40 to 60 years. There are several types of metal roofing systems available, including corrugated galvanized steel, aluminum, zinc, and tin, tile sheets, copper, coated or stainless steel. Some metal roofs even come with integrated solar or integrated snow removal systems.
Metal roofing has a finished look, strong fire resistance ratings, and is stronger and more sustainable than many other options. However, metal is susceptible to corrosion, so modern metal roofs have protective surface layers added to manage damage from exposure, moisture, pollution, and other environmental factors.
2. Built-up Roofing Membrane
Built-up roofing (BUR) membrane is one of the oldest and most flexible roof types. It is made by alternating layers of tar and gravel and has a lifespan of 20 years or more with care. The number of layers affects durability and cost. BUR roofing is inexpensive and easy to repair. It holds up well to foot traffic but depends on its stable understructure to carry the weight and vibrations of movement. It is UV-resistant and may be coated to reflect heat. The downside of BUR roofing is that its lifespan is one of the shortest around, and it can be difficult to identify the source of a leak as the roof ages.
3. Green Roof
Green roofing is a sustainable masterpiece that can last from 30 to 50 years. It consists of a tough waterproof membrane covered completely by green plants. Green roofs improve air quality and often add a green space for relaxation and rest for employees.
Advantages of green roofs include protection from the elements, possible utility and government incentives, and improved aesthetics. Often they have sophisticated water and drainage management, climate control, and sensor capabilities.
The downside of green roofs is that they require ongoing maintenance and monitoring.
4. Spray-On Roofing
Spray Polyurethane Foam (SPF) roofing is an eco-friendly roofing material that begins as a liquid spray that instantly expands into a foam, which hardens into a solid layer. This roofing system waterproofs and adds an insulating factor. It can be used in any climate and will last up to 50 years with correct installation and maintenance.
The downside of SPF roofing is that the installation window is limited to favorable weather conditions (no snow, no ice, no water), and once installed, SPF roofing should be inspected once or twice a year.
5. Thermoset EPDM Membrane
Thermoset EPDM membrane is a durable synthetic rubber roofing membrane that offers strong resistance to sunlight and pollution. It’s long-lasting, versatile, and easy to install. EPDM comes in white and black rolls, and in addition to sun and pollution resistance, this single-ply rubber is durable in the face of many common solvents like alcohol or acids.
The downside of EPDM is that it is not necessarily the “prettiest” option on the market, and it can puncture easily (think falling debris or people walking on the roof).
6. Thermoplastic PVC and TPO Roof Membranes
Thermoplastic PVC and TPO roofing systems are adverse conditions resistant. UV light, chemicals including fats and oils, or bacterial growth are all slow to damage these types of roof membranes. They are lightweight, heat-reflective, and puncture resistant.
Other benefits include strong air-welded seams, fire-resistance, and tolerance of both high temperatures and high winds.
The downside of TPO roofing is that you should beware of cheap, poorly made products. Since TPO has become so popular, many small manufacturers have tried to create their product lines, allowing quality to slip through the cracks. Be sure to purchase this type of product from a reputable manufacturer.
7. Shingle
Shingles are commonly seen on residential buildings but are also used on commercial properties, typically ones that have steep roof lines. Shingles come in numerous materials, including asphalt, architectural, slate, plastic, and ceramic.
Shingle roofing is relatively easy to install, affordable, and versatile. However, depending on the brand used, lifespan isn’t as long as some of the other commercial roofing types. Shingles are also susceptible to mildew and moss if your building is located in a shaded area.
What’s the Right Roof?
When choosing the right roof for your commercial property, it is essential to consider several factors such as the roof’s visibility, foot traffic, exposure to chemicals, wind, and temperature extremes. Different climates and building usage should also influence your roofing material choices.
It is crucial to consider the longevity of the roof and its annual maintenance costs. In addition, you should also think about the energy costs of the various types and colors of roofing materials. For instance, a dark-colored roof may reduce heating bills in cold weather climates, while warm climate offices may require a white roof to limit the strain on their air conditioner.
It is also essential to consider warranties when choosing the right roof. Look for a roofing contractor who offers a warranty for their work and the materials used. This will ensure that you are protected in case of any issues with your new roof.
Overall, selecting the right roof for your commercial property requires careful consideration of several factors. By taking the time to evaluate your options, you can choose a roof that meets your needs and provides long-lasting protection for your property.
