Everything You Must Know about Modified Bitumen Roofing

Everything You Need to Know About Modified Bitumen Roofing

Modified Bitumen roofing has been around since the 1960s when it was first developed as an improvement on built-up roof (BUR) systems. Since then, it has become increasingly popular due to its long lifespan, flexibility, and resistance against extreme weather conditions such as hail or high winds. 

So if you’re looking for an efficient way to protect your home or business building from harsh elements without breaking the bank – modified bitumen may be exactly what you’re looking for! Read on for more information about this type of roofing system and how it can benefit you in the long run.

What is Modified Bitumen Roofing?

Modified bitumen roofing is an advanced form of asphalt-based roofing. It combines traditional bitumen with polymers, creating a reinforced material that’s much more durable than regular asphalt and other waterproofing materials. This type of roofing provides superior protection against the elements, making it ideal for many commercial applications. The installation process is also simpler compared to other roofing materials, providing added convenience for those who need to replace or repair their roofs quickly.

Unlike some other forms of modified roofing, modified bitumen does not require any additional coating after installation. This makes it both cost-effective and easier to install since there’s no extra step involved in the process. Additionally, because of its corrosion resistance properties, modified bitumen can last up to 30 years if correctly installed on a flat surface area. Moreover, this type of membrane has excellent adhesion qualities, allowing it to be applied directly onto substrates such as concrete or metal sheets without needing additional primers or sealants.

Benefits of Modified Bitumen Roofing

Modified bitumen is a popular roofing choice for many commercial and industrial spaces due to its numerous benefits.

  • Durability

    Modified bitumen is designed to withstand harsh weather conditions such as heavy rain, strong winds, and hail. This is because it is made with polymer-modified asphalt, which gives it increased flexibility and resilience. Additionally, it is reinforced with fiberglass or polyester to improve its strength and durability. These features make this roofing a long-lasting and cost-effective roofing solution for commercial and industrial buildings.

  • Flexibility

    It is very flexible, which allows it to conform to a variety of roof shapes and sizes. It can be installed on flat or sloping roofs, making it ideal for buildings with complex roof designs. Additionally, it can be applied using a variety of installation methods, including torching, hot-mopping, and cold adhesive, making it a versatile roofing material.

  • Energy Efficiency

    This type of roofing is resistant to the growth of mold and mildew, which minimizes the need for frequent cleaning. This can help to lower energy costs by reducing the amount of air conditioning needed to cool the building. Reflective coatings can also be added to further improve its energy efficiency.

  • Low Maintenance

    Bitumen roofing requires minimal maintenance, making it a popular choice for commercial and industrial buildings. It’s also resistant to the growth of mold and mildew, which minimizes the need for frequent cleaning. Additionally, its smooth surface makes it easy to clean when necessary, making it low-maintenance and cost-effective roofing solution.

  • Easy Repairs

    In the event that a modified bitumen roof is damaged, it is easy to repair using patching materials. This can save building owners the cost of a full roof replacement. Additionally, it can be overlaid with new roofing material, which can extend its lifespan even further. These features make it a practical and cost-effective roofing solution that is easy to repair and maintain.

Different Types of Systems

Everything You Need to Know About Modified Bitumen Roofing1

Bitumen roofing systems are highly popular among commercial and industrial buildings. There are several different types of modified bitumen membranes available, each with its own pros and cons.

Styrene Butadiene Styrene (SBS)

SBS roofing is typically manufactured with a rubber-like material, which delivers greater flexibility and durability. This type of roofing is often utilized for low-slope roofs and can be installed through several techniques, such as torching, hot-mopping, and cold adhesive.

Atactic Polypropylene (APP)

APP roofing is a type of roofing system designed to improve the performance of traditional asphalt roofing. It is made by adding APP to a standard asphalt mix, which creates a plastic-like material that provides increased resistance to UV rays and high temperatures.

Hybrid

Hybrid modified bitumen is also a popular choice for commercial and industrial buildings due to its durability and high resistance to UV rays and high temperatures. It has the features of both APP and SBS roofing, which makes it an excellent option for many.

Self-Adhering

This roofing is designed to be self-adhering, eliminating the need for torching or hot-mopping during the installation process. It is commonly used on low-slope roofs and can be applied directly to the roof deck using a peel-and-stick method.

Cold-Applied

Cold-applied roofing is applied using a cold adhesive, also eliminating the need for torching or hot-mopping during installation. It is commonly used on low-slope roofs and can be applied directly to the roof deck using a brush or roller.

Installation Process

When it comes to roofing installation, the process is surprisingly easy. It’s a straightforward system that requires few tools and minimal labor, but a help from Sarasota’s Top Roofing Company will make a long mile. The installation process for this type of roofing typically involves the following steps:

  1. Prepare the roof surface: To guarantee proper adhesion of this roofing system, the roof surface must be thoroughly cleaned and prepared. This step may involve eliminating any pre-existing roofing material, fixing any impaired areas, and verifying that the roof is free of debris and moisture.
  2. Install the base sheet: A base sheet is typically installed to provide a smooth surface for the roofing system to adhere to. The base sheet can be attached using various methods, including hot-mopping, torching, or cold adhesive.
  3. Install flashing and other roof accessories: Flashing and other roof accessories, such as drip edges and roof vents, are then installed to provide additional protection against water intrusion and to ensure proper ventilation.
  4. Apply the membrane: The roofing membrane is then applied to the base sheet using the appropriate installation method for the specific roofing system being used. This may involve torching, hot-mopping, or cold adhesive.
  5. Inspect and finish the roof: Once the roofing system is installed, it is important to inspect the roof to ensure that it is properly sealed and that all components are functioning properly. The roof may then be finished with a reflective coating or other protective layers to increase its energy efficiency and longevity.

Maintenance Repair

Bitumen roofing requires regular maintenance and repair for optimal performance. Maintenance should be performed at least once a year or as soon as any signs of damage are visible to avoid costly repairs further down the line. Bitumen roof maintenance typically involves an inspection of all components, including flashing, fasteners, and sealants. Any issues that arise must be addressed promptly in order to prevent them from becoming bigger problems.

When it comes to modified bitumen roof repair, there is no one-size-fits-all solution; the type of repair required depends on the specific issue being faced. For example, if a crack has appeared in the membrane, then patching may be necessary; however, if a puncture has occurred due to debris falling onto the surface of the roof, then replacement may be needed. In either case, proper installation techniques must always be followed when carrying out repairs to ensure that they last long-term. Additionally, it’s important to use products specifically designed for bitumen roofs in order to guarantee maximum protection against water infiltration and other damages.

Final Thoughts

When it comes to roofing, modified bitumen is an excellent choice. It’s durable and cost-effective, while also providing good protection against the elements. As with any type of roofing system, there are a few key considerations you need to keep in mind when choosing this option. You’ll want to look at different types of modified bitumen systems, as well as weigh up installation costs and maintenance requirements.
