However, with so many roofing contractors out there, it can be challenging to find the right one to install or maintain your modified bitumen roof. In this article, we will guide you on how to choose the best roofing contractor for your modified bitumen roof, ensuring a successful and long-lasting investment.

So, if you want to make an informed decision and get the most out of your roof, keep reading!Modified bitumen roofs are a popular choice for commercial buildings due to their durability and waterproofing capabilities. These roofs are made from a combination of asphalt and rubber modifiers, making them highly resistant to extreme weather conditions. But what exactly is a modified bitumen roof and how does it differ from other types of roofs?To put it simply, a modified bitumen roof is a type of built-up roofing system that is designed to provide superior protection against water intrusion. It is composed of multiple layers of roofing felt, coated with a layer of bitumen and reinforced with fiberglass or polyester.

This combination of materials gives modified bitumen roofs their strength and flexibility, making them ideal for flat or low-sloped roofs. Now that we have a better understanding of what modified bitumen roofs are, let's take a closer look at the materials used in their construction. The most common materials include asphalt, rubber modifiers, and reinforcements such as fiberglass or polyester. Asphalt is the main component of these roofs and provides the waterproofing properties that make them so effective. Rubber modifiers, on the other hand, add elasticity to the asphalt, making it more resistant to cracking and tearing.

Lastly, reinforcements help to improve the overall strength and durability of the roof. One of the main benefits of modified bitumen roofs is their versatility. There are three main types: SBS, APP, and hybrid. SBS (Styrene Butadiene Styrene) roofs are made with rubber modifiers that give them enhanced flexibility and are best suited for areas with extreme temperature variations. APP (Atactic Polypropylene) roofs are made with plastic modifiers that give them excellent UV resistance and are ideal for warmer climates.

Hybrid roofs combine both SBS and APP modifiers to create a well-rounded roofing system that can withstand a variety of weather conditions. When it comes to choosing the right type of modified bitumen roof for your commercial building, it's important to consider factors such as climate, building structure, and budget. Consulting with a roofing professional can help you determine which type of roof will best suit your specific needs. Proper installation is crucial when it comes to ensuring the longevity and effectiveness of your modified bitumen roof. It's important to choose a reputable and experienced roofing contractor who has a thorough understanding of the installation process and uses high-quality materials. Don't be afraid to ask for references or to see examples of their work before making a decision. Maintenance and inspections are also key in keeping your modified bitumen roof in top condition.

Regularly checking for any signs of damage or wear and tear can help catch and prevent any potential issues before they become major problems. Additionally, investing in proper waterproofing techniques can greatly extend the lifespan of your roof and protect against water intrusion. In conclusion, when it comes to choosing the right roofing contractor for your modified bitumen roof, it's important to do your research and consider all aspects of the roof's construction, type, installation, and maintenance. By following these tips and guidelines, you can ensure that your commercial building has a reliable and long-lasting roof that will protect it for years to come.

Maintenance, Inspections, and Waterproofing

Keep Your Roof in Top ConditionTo ensure the longevity of your modified bitumen roof, regular maintenance, inspections, and waterproofing are crucial. These tasks should be performed by a professional roofing contractor who is experienced in working with this type of roofing material. Maintenance should include removing debris, cleaning gutters, and checking for any damage or wear and tear.

Any issues should be addressed promptly to prevent further damage. Regular inspections can also help identify potential problems early on, allowing for timely repairs and avoiding costly replacements. Another important aspect of maintaining a modified bitumen roof is proper waterproofing. This involves applying a protective layer to prevent water from seeping into the roofing material and causing damage. The type of waterproofing used will depend on the specific type of modified bitumen roof and the materials used in its construction. By keeping up with maintenance, inspections, and waterproofing, you can ensure that your modified bitumen roof stays in top condition and provides long-lasting protection for your commercial building.

Types of Modified Bitumen Roofs

Modified bitumen roofs are a popular choice for commercial buildings due to their durability, affordability, and ease of installation.

However, not all modified bitumen roofs are created equal. There are different types of modified bitumen roofs available, each with their own unique characteristics and benefits. The first type is the traditional multi-ply modified bitumen roof, which consists of multiple layers of bitumen and reinforcing fabrics. These roofs are known for their strength and longevity, making them a great option for high-traffic areas. They also offer excellent waterproofing capabilities. The second type is the single-ply modified bitumen roof, which is made up of a single layer of bitumen and a polymer modifier.

This type of roof is more flexible and lightweight compared to the traditional multi-ply, making it easier to install and repair. It also offers good resistance to UV rays and can be installed with a self-adhesive backing for added convenience. The third type is the cold-applied modified bitumen roof, which eliminates the need for hot asphalt during installation. This makes it a safer and more environmentally friendly option. It also offers excellent waterproofing capabilities and can be applied in a variety of temperatures. When deciding which type of modified bitumen roof is right for you, consider factors such as your budget, climate, and building's needs.

If you have a high-traffic area that requires extra durability, a traditional multi-ply roof may be the best option. If you're looking for a more lightweight and easy to install option, a single-ply roof may be a better fit. And if you want an environmentally friendly option, the cold-applied roof may be the way to go.

Materials Used in Construction

When it comes to modified bitumen roofs, there are various materials used in construction. These materials play a crucial role in determining the durability, performance, and overall quality of your roof.

Here are some of the benefits and drawbacks of the most commonly used materials for modified bitumen roofs.


Asphalt is a popular choice for modified bitumen roofs due to its affordability and easy installation process. It is also highly resistant to UV rays and provides excellent waterproofing properties. However, asphalt can be prone to cracking and damage over time, especially in extreme weather conditions.


Rubber is another commonly used material for modified bitumen roofs. It is highly flexible, making it ideal for roofs with complex shapes and structures.

It also has excellent waterproofing properties and can withstand extreme temperatures. However, rubber can be more expensive than other materials and may not be suitable for all types of roofs.


Plastic is a lightweight and cost-effective material that is often used in modified bitumen roofs. It is resistant to UV rays and can withstand harsh weather conditions. However, plastic may not be as durable as other materials and may require more maintenance over time.


Fiberglass is a strong and lightweight material that is commonly used as a reinforcement layer in modified bitumen roofs.

It provides added strength and stability to the roof, making it more resistant to damage. However, fiberglass can be expensive and may not be suitable for all types of roofs. Overall, each material has its own benefits and drawbacks, so it's important to consider your specific roofing needs and budget when choosing the right material for your modified bitumen roof. Consulting with a reputable roofing contractor can also help you make an informed decision and ensure that your roof is installed using high-quality materials.

Choosing a Reliable Contractor

When it comes to getting your modified bitumen roof repaired, installed, replaced, or inspected, it's important to find a reliable and reputable contractor for the job. With so many options out there, it can be overwhelming to choose the right one.

But by considering these important factors, you can ensure that you make the best decision for your commercial roofing needs.

1.Experience and Expertise

One of the most crucial factors to consider when choosing a contractor is their experience and expertise in dealing with modified bitumen roofs. Look for a company that has a proven track record of successfully completing similar projects and has a team of skilled professionals who are knowledgeable about different types of roofs and materials used in construction.

2.Reputation and Reviews

Another important aspect to consider is the reputation of the contractor. Check online reviews and ask for references from previous clients to get an idea of their work quality and customer service. A reputable contractor will have positive reviews and satisfied customers who can vouch for their services.

3.License and Insurance

It's crucial to choose a contractor who is licensed and insured.

This ensures that they have met all the necessary requirements and have the proper training and qualifications to work on your roof. Insurance also protects you from any liability in case of accidents or damages during the project.

4.Communication and Customer Service

A reliable contractor should have good communication skills and provide excellent customer service. They should be responsive to your inquiries and keep you informed throughout the project. This shows that they value their clients and are committed to providing a positive experience.

5.Cost and Contract

Finally, consider the cost and contract before making a decision.

While it's important to stay within your budget, don't automatically go for the cheapest option. Look for a contractor who offers a fair price for their services and has a well-written and detailed contract that outlines the scope of work, timeline, and payment terms.
