Flat Roof Types: What You Should Know About Modified Bitumen Roofs

Without a doubt, modified bitumen is one of the most popular flat roof materials in the market. Although it wasn’t a pioneer, it has evolved from an innovative solution to one of the expected top rankers for many households in the international roofing community.

There are several reasons behind this fame. Understanding the phenomenon of modified bitumen roofs will help you feel natural in choosing from numerous roof systems, no matter how many square feet you will need to cover with a selected material. Let’s get straight into the topic!

What Is Modified Bitumen?

There are several related terms that can describe such roofing systems, which can only lead to more confusion among end users:

  • In the most typical case, this membrane roof system consists of two plies, which lets people consider it one of the simplest styles of BUR building roofs. Although the latter usually has more layers and asphalt as its main material, both of them are high-ranked flat roof types.
  • Modified bitumen is the next generation of built-up roofing systems, which are great for flat and low-scoped surfaces. Contrary to their predecessor, more modern flat roof materials are used in this case — from waterproof membranes to fiberglass reinforced coatings. With the help of extra coatings as additional protective layers, this solution can reflect heat better and be less prone to premature breakdowns because of the exposure to ever-changing weather conditions.

Benefits of Modified Bitumen Flat Roofing

Let’s take a closer look at what features has allowed such surfaces to be a frontrunner in the modern market for flat roofing systems:

  • The analyzed construction is known for its tear resistance. So despite what weather conditions it might face, this surface isn’t prone to immediate damage and can last for decades. What’s more, modified bitumen flat roof types are recognizable for their ability to withstand pretty heavy foot traffic, which is a significant problem for some alternative versions, where your access has to be minimized.
  • Water damage is one of the significant challenges for owners of flat roofs, but modified bitumen helps to minimize risks thanks to its natural waterproof characteristics. If you contribute to its efficiency by removing debris, then you have nothing to worry about.
  • Since it doesn’t lose its integrity in the long run, you won’t have to take care of repair or reinstallation in the nearest future after the project is ready. The less hassle, the better. If you still face problems like leaks, they can be fixed really fast and don’t cause damage to the entire construction.
  • When it comes to how well this flat roof type can reflect heat, end users are usually surprised when they see their energy bills — modified bitumen surfaces are surely best friends of people from this perspective.

DIY vs. Professional Contractors’ Assistance

It is possible to install modified bitumen flat roof systems on your own, but this process will be quite a hassle for beginners and amateurs. However, working with experts will definitely bring more positive results at the end of the day:

  • Whether you need to reinforce the system with uniform slabs for membrane roof systems or get rid of the water damage consequences, applying for local roof contractors’ assistance is a smart choice.
  • Professional third parties can help in selecting certain specifications to install in your flat roof system. Compared to other flat roof types, modified bitumen constructions are extremely durable. So it is quite disappointing to lose this potential because of the lack of knowledge and non-taking into account all the needed details. For instance, specialists come in handy when you need to pick up the most efficient installation method. The torch approach will require different technologies and gear than roof roofs based on cold adhesives or asphalts.
  • There are several additional services, where the assistance of local roof contractors is more than just sufficient. For example, it is a nice way to take care of the drainage system of the roof and ensure you won’t reduce its water resistance because of side factors.

Final Thoughts: Are Modified Bitumen Flat Roofing Systems Worth It?

The answer won’t be surprising. Despite how many individual factors might be present and influence your decision-making, it is clear that such surfaces are definitely durable and reliable choices. Not only aren’t they complicated to maintain in the long run, but they also don’t require huge flat roof replacement costs and repair expenditures.
