Modified Bitumen SBS Roofing

Guard Your Business With Iron Shield


When it comes to protecting your business property, you need a roofing team who is thoroughly versed in the ins and outs of commercial roofing. After all, commercial roofs are different not only in size and scope, but in their fundamental structure, as they are often flat.

Due to this particular aspect of commercial roofing systems, one of the most popular options is using an SBS-modified bitumen roofing system as they are a reasonably-priced option with great longevity and durability against harsh weather.

At Iron Shield Roofing, we can apply this commercial roofing system using either a torch or cold application, depending on what’s best for your particular roofing needs. To get started with a roofing consultation, simply give us a call today.  We’ll go over all the different commercial roofing options and help you pick one that works best for your business.

We Have A Wide Range Of Commercial Roofing Capabilities

At Iron Shield Roofing, we put our expertise to work on a variety of different commercial roofing projects. Many businesses (such as restaurants or manufacturing warehouses) have vastly different roofing needs, and our team is here to help guide you in the right direction.

Generally speaking, Iron Shield services these types of commercial properties:

  • Business parks

  • Restaurants

  • Hotels and motels

  • Strip malls

  • Retail stores

  • Warehouses

However, if you don’t find your specific type of building here, don’t hesitate to give us a call anyway. Chances are, we can still help you out. If not, we can at least point you in the right direction.


A bitumen roof is, in essence, made up of different layers of ABS plastic that are topped with a bitumen and polyester blended gravel adding system for additional strength. This type of roofing system is designed with a low-slope (aka flat) roofing system in mind. 

At Iron Shield, we use an SBS (styrene-butadiene-styrene) modified bitumen system. Putting the jargon aside, what this means is that you’ll have a flexible roofing membrane with greater expansion and contraction capabilities. The synthetic rubber used also ensures increased flexibility. It has the ability to stretch up to six times the length of regular modified bitumen, all while not losing its elasticity.


Benefits of Modified Bitumen

As we said earlier, modified bitumen is one of the most popular choices for commercial roof replacements, and for good reason. These roofs have a plethora of benefits that make them great choices for most commercial properties. Here are few:

Thanks to its elastic nature modified bitumen roofs have great resistance to extreme changes in temperature, making them an especially good choice in Edmonton, Alberta, and the surrounding areas. Not only that, but their flexibility also allows them to accommodate minor structural shifts from the building itself.

Dealing with potential water damage is especially important for commercial roofs. Low-slope or flat roofs have the added danger of giving water the opportunity to pool and leak. When you install a modified bitumen roof, you can rest assured that you are getting one of the most water-resistant roofs available on the market.

Modified bitumen’s water and air tight nature doesn’t just provide great protection against water damage, it also has great insulation properties that lead to increased energy efficiency for your entire building. This not only affects your energy bill, but it also puts less strain on your heating and cooling unit, saving you money all around.

Another test of a roof’s durability is how well it stands up against harsh weather conditions. When subjected to hail, wind, and fire damage tests, modified bitumen systems get consistently high rankings. They stand up well against fierce storms and ensure your assets, and more importantly, your people, are well protected.

These roofs are designed to last between 15 and 20 years. They can last even longer with proper maintenance and care. On top of that, repairs are easily accomplished through bitumen patches. High-quality installation work will also ensure that seals and flashing stay secure and leak-free.

Modified Bitumen Installation Methods

When using a heat method for installing a modified bitumen roof, we generally follow this installation process:


  • A complete commercial roof inspection, including removal of the old roof to inspect the substrate

  • Make any necessary changes to ventilation, substrate, etc. before roof construction begins

  • Lay down ABS plastic paper and particle board

  • Apply the first layer of bitumen and polyester gravel using a roofing torch (the first layer alone is sufficient for waterproofing)

  • Add a granule-covered layer cap to protect the coating from UV light

  • Add additional roofing elements, like flashing, to complete the installation


On the other hand, cold adhesive techniques utilize specialized solvents that, when they evaporate from the adhesive, allows the components to bond to the membrane, creating a sort of solvent weld.
