Commercial Roofing Material Comparison
Commercial roofs often use different materials when compared to residential roofs. When evaluating materials, you’ll start by reviewing which roof type you have: low or steep slope. Low slope is more common and is classified as a slope with a pitch that is less than 3-in-12.
Property managers should understand both roofing types for the best understanding of commercial roofing. Commonly, steep slope roofs are present on multifamily and condominium properties.
Low-Slope Roofing Materials
You’ll find these roofs on shopping centers, office buildings and many industrial facilities. Here’s a look at the options for low-slope roofs.
TPO: Dating back to 1991, TPO roofing is short for thermoplastic polyolefin. It is a single membrane material. This durable roofing material is quite popular and roofers like it because it is easy to install. It’s also an affordable option.
EPDM: This type of ply membrane roofing is sometimes called rubber roofing. It is another very common commercial roofing material that is widely used on roofs. It can be designed to hold gravel, which can protect the roofing membrane and help make the roof fireproof.
Built Up: You might see this roofing material shortened to BUR. It uses a method of layers of reinforcing fabric and bitumen. It then gets a layer of ballast (gravel) on top. The top gravel layer helps protect the roof and provide fireproofing.
Modified Bitumen: This asphalt-based roofing material is similar to a built-up roof. The process starts with an insulation layer and then alternates modified bitumen membrane layers. It is one of the most waterproof roofing options, which makes it a popular option in moist climates or properties that face harsh weather.
Metal: One of the most durable and low-maintenance roofing options is metal. The most common roofs you’ll find these on include industrial properties and warehouses. Sometimes there’s only a small section of metal roofing as a design element. Before going with this material, make sure your contractor has the skill set and experience to install these roofs.
PVC: This single-ply membrane roofing is similar to TPO and EPDM. Many commercial properties use these roofs because they are durable, energy-efficient and last a few decades. However, it is more expensive than TPO or EPDM in most cases.
You have many options for steep slope roofs. Take a look to familiarize yourself with your options before embarking on a project.
Asphalt: If you’re a homeowner, you’re likely familiar with asphalt roofs. You’ll encounter these roofs if you manage apartments or condos or other small commercial buildings. This roofing process involves a plywood sub-roof, a moisture barrier and then nailing down shingles in layers.
Metal: You’ll find metal roofs on both low and steep slope roofs. You’ll commonly see these on industrial buildings, self-storage facilities and as an accent or design element on a variety of roof styles.
Tile: You won’t find these roofs very often in Washington. They are far more common in the southwest. Tile roofs can be made from clay, slate, terracotta or concrete. Because these roofs are rare, make sure your contractor is up for the job and has the skillset to install these roofs. If you can afford the roof, it is good for fire resistance and durability.
Explanation of Commercial Roofing Services
Commercial roofing includes an array of services. Your roofing team can help with everything from inspections to replacements. Here’s a look at some services a commercial roofer can provide.
Roof inspections: It’s a good idea to complete annual roof inspections. That way, you learn of any issues before they become dire. Many roofers can now complete these inspections via drones or even satellite imaging. An inspection can help you file an insurance claim after a storm. That’s because you’ll have documented proof of the roof’s status before the storm and can show that the damage is not usual wear and tear.
Roof repairs: As your roof ages, your annual inspection will likely show the need for repairs. Identifying these needs early can help prevent full roof replacement. Roofs often start to lose shingles as they age and might need gutter fixes or membrane repairs due to punctures. Prevent leaks by completing recommended repairs quickly.
Roof coating: This can help extend the life of your roof and improve its energy efficiency. Coatings can be in silicone, polyurethane, acrylic and asphalt. This is a more specialized service that you might need to shop around for because many commercial roofers do not provide it.
Insurance claims: When severe storms hit your area, a commercial roofing contractor can aid in your insurance claim for storm damage. Navigating the insurance claim process can be complex and having a good contractor alongside you can be a true asset when dealing with insurance adjusters.
Roof replacements: No matter the commercial roofing materials you use on your building, the day will come when it’s time to replace the materials. Many commercial roofs are large and require a great deal of capital. You should be budgeting and planning for this throughout the life of your roof. The project could take up to a week depending on the size of the building. Counsel your roofing contractor to learn more about what to expect and how to prepare your tenants or business partners.
