The Complete Guide to the Different Types of Commercial Roof Systems

Has your commercial roof run its course? Looking to install commercial roofing for the first time? If so, you have a number of systems to choose from. 

These commercial roof systems differ not only in terms of durability but in terms of maintenance, insulation, and a variety of other characteristics as well. Looking to learn more about them? Then read on.

This is a complete guide to the different types of commercial roofing systems. 

Silicone Roofing

At the top of our list for a reason, silicone roof coating provides tremendous value. Whether you are installing a brand new roof or renewing a weathered one, silicone roof coating is a proven way to extend the life of your commercial roof. The material is very strong and durable, and creates a layer of protection between your roof and the elements. 

Silicon coating applications can often last between 15-20 years, saving you money on future roof repairs and replacements. It also provides protection against ponding on flat roofs. Metal roofs are commonly restored using Silicon roofing systems as well.

Additional benefits of a silicone roof system include quick cure time, low odor, and no need for prior tear off as it can go directly over existing surfaces. These roofing systems are also CRRC compliant, which helps save on energy as well.

Elastomeric Acrylic

Elastomeric Acrylic coatings are formulated to increase seamless protection to your commercial roof. It’s a lighter material and very durable to withstand bad weather, leaks, sunlight wear and tear and ultimately restores your commercial roof to its full potential.

It is a watertight seal which covers everything including flashings, vents, and protrusions. Even better, it does not contain any VOCs. Elastomeric Acrylic Systems have a general life span of 10 to 20 years.

Built-up Roofing

Sometimes called BUR, built-up roofing is a form of roofing which consists of layers of tar, gravel, and ply sheet. The more layers that are added, the more durable (and insulative) the roofing becomes. Easy to fix and maintain, it offers a great deal of versatility throughout the years. 

BUR has been used for years and is one of the most common flat roofing materials around. Fire-resistant, crack-resistant, and waterproof, it’s both protective and tough. It’s also one of the cheapest commercial roofing materials in existence, making it perfect for those on a budget.

The downside to built-up roofing? It’s heavy. As such, it can put quite a bit of stress on a roofing structure. 

Modified Bitumen

Modified bitumen is similar to built-up roofing in that it’s layered. However, whereas built-up roofing consists of 5 or more layers, modified bitumen consists of two. Plus, whereas built-up roofing is systematically installed one layer at a time, modified bitumen comes in ready-to-install strips. 

Performance-wise, the materials are similar as well. Both designed for low-slope commercial roofs, they’re resistant to water damage, sun damage, and cracking. 

Note, however, that modified bitumen possesses greater tensile strength than does built-up roofing. As such, it’s more appropriate for situations in which it’s experiencing regular stress (ie. people walking on it). Plus, it holds up better through severe temperature changes. 

Cost-wise, modified bitumen exceeds built-up roofing (though not by much). That said, it also tends to last longer. Therefore, it generally provides more bang for its buck in the long-run. 

TPO Roofing

Also known as a thermoplastic roof membrane, TPO roofing is a roll-on material that can be installed quickly and efficiently. Possessing strong seams, it’s durable and easy to maintain. 

TPO roofing is resistant to essentially everything that comes toward it, including but not limited to sunlight, water, fire, chemicals, animal-based oils and fats, heat, and cold. Its resistance to animal oils and fats, in particular, makes it ideal for use on the tops of restaurants. 

In addition to its superb resistance capabilities, TPO roofing is also highly reflective of sunlight. As such, it offers excellent insulation in warm climates. 

The biggest issue with TPO roofing is that it’s on the expensive side. That said, it’s not much more expensive than EPDM roofing.
