Why Michigan Business Owners Choose Modified Bitumen Roofs

As a seasoned roofing professional, I’ve had the privilege of working on numerous commercial roofing projects throughout Michigan. One roofing solution that has consistently proven its worth for businesses is modified bitumen. 

In this blog post, I will share insights into why Michigan business owners prefer this roofing system over others and offer a comprehensive view of its durability, cost-efficiency, and adaptability to the region’s unique climate.

Understanding Modified Bitumen Roofing Systems

Before delving into the numerous benefits of this roofing system, let’s clarify what this roofing material is.

Modified bitumen, or modified asphalt, is a durable and long-lasting roofing solution designed explicitly for low-slope or flat roofs. It’s a single-ply roofing membrane made from asphalt and fortifying materials, which enhance its flexibility and performance. Unlike traditional asphalt rolls and shingles, modified bitumen combines layers of this material with rubber, plastic, and fiberglass to create a highly resilient and watertight surface.

Now, let’s explore the compelling reasons behind Michigan’s preference for this roofing option.

Benefits Of Modified Bitumen Roofs For Michigan Building Owners

From enhanced weather protection and durability to savings, modified bitumen roofs offer multiple benefits to property owners in Michigan.

Modified Bitumen Roofs

#1 High Durability

Michigan’s climate can be fierce, with cold winters and dramatic temperature fluctuations. Modified bitumen membranes are renowned for their average durability of 20 years, which makes them ideally suited to withstand the state’s demanding weather conditions.

#2 Weather Resistance

These roofs are designed to endure extreme temperature variations, from freezing winters to scorching summers. The materials used to make the membrane help it contract and expand without cracking, ensuring protection against temperature-related damage. 

#3 Superior Waterproofing

Modified bitumen roofs offer outstanding waterproofing capabilities. Their multiple layers, often fused with torches or adhesives, create a seamless and impenetrable barrier against rain, snow, and ice. This durability is particularly critical in Michigan, where heavy precipitation can occur.

#4 Snow Load Resistance

Michigan’s heavy snowfall during the winter months can put immense stress on roofs. Modified bitumen’s robust structure and waterproofing capabilities help prevent snow from infiltrating and causing damage, ensuring the structural integrity of the building.

#5 Ice Dam Prevention

The freeze-thaw cycle common in Michigan can lead to ice dam formation on roofs. Modified bitumen’s waterproofing qualities and strong seams reduce the risk of ice dams, preventing potential water damage and leaks.

#6 Easy Installation

Another reason Michigan business owners favor modified bitumen membranes is the relatively straightforward installation process. This roofing system can be installed quickly, minimizing disruption to business operations. It also offers flexibility in terms of installation methods, including torch-applied, cold-applied, and self-adhered systems.

#7 Cost-Efficiency

For business owners, cost-effectiveness is a top priority when investing in roofing solutions. Modified bitumen roofing systems excel in this regard, providing a remarkable return on investment.

The Average Cost Of Modified Bitumen Roofs

The cost of modified bitumen roofing varies between $4.00 and $7.50 per square foot, and these costs are contingent on factors such as the size and shape of the roof, the slope, and whether the project encompasses any repair work or the removal of an existing roof.


The lifespan of a modified bitumen roof typically exceeds that of traditional roofing materials. With proper maintenance, these roofs can last even 25 years, making them a sound financial investment.

Energy Efficiency

Michigan’s climate variations also include hot summers. Though modified bitumen roofs are black in color, you can purchase coatings that allow you to make it reflective, and therefore, more energy efficient. This added energy efficiency contributes to long-term savings, so ensure you get a coating for your modified bitumen roofs.

Easy Maintenance

Maintaining modified bitumen roofs is relatively simple, further reducing long-term costs. Periodic inspections and minor repairs, if necessary, can extend the roof’s lifespan, avoiding the need for premature replacements.

As a roofing professional, I’ve seen the positive impact a new modified bitumen roof has on businesses, providing peace of mind and protection against Michigan’s challenging climate. If you’re a Michigan business owner looking for a roofing solution that combines strength, cost-effectiveness, and reliability, you should consider getting a high-quality modified bitumen roof for your building. Your investment in this roofing system will undoubtedly pay dividends in the years to come. But for that, you need to make sure you are choosing the right manufacturer and installer.
