Bituminous roofing materials have endured the test of time and have a track record of success in low-slope roofing. Bituminous roofing systems are renowned for their resilience, dependability, and exceptional water resistance. Built-up roofing (BUR) Built-up roofing (BUR) and polymer-modified, multi-ply bitumen are the two most common bituminous roof system types. The two most prevalent polymer-modified bitumen membranes on the market are SBS and APP. BUR systems consist of alternate layers of oxidized bitumen and bitumen-coated membranes, often known as felts or ply sheets. Typically, ply sheets are fortified with high tensile strength, dimensionally stable fiberglass mats. BUR systems are coated with aggregate or a roof coating to strengthen their resistance to the elements, and the robust, multi-ply design provides decades of reliable waterproofing. 
Modified Bitumen Systems (Modbit) Modbit systems include foundation sheets and a cap sheet, and they share the same primary waterproofing advantages as a BUR system. Modbit systems are highly flexible. SBS membrane SBS membranes are comprised of bitumen treated with elastic Styrene-Butadiene-Styrene (SBS) polymers to create a "rubberized" asphalt layer. The coating is applied on a reinforcing carrier made of fiberglass for high tensile strength and stability, polyester for better elongation and tear strength, or a mix of the two materials. Self-adhering SBS membranes are possible, however, they are typically put using sweeping asphalt or cold adhesive. APP membranes APP membranes are composed of bitumen that has been changed with polymeric Atactic Polypropylene (APP) polymers, leading to a covering with the widest temperature range as well as enhanced durability and tensile strength. Due to the malleability of the polymeric bitumen, APP membranes are often applied with a torch. 
modified bitumen roofing installation
The installation process of modified bitumen roofing is as follows:
- Ensure that your flat roof is free of all debris.
- Cover your deck, old roof, or insulation with strong roofing felt. Using cap nails, secure the felt in rows along the top and bottom of the sheets, as well as in the center.
- Install drip edge flashing and prime it so that it will adhere to the roofing material.
- Leave a few inches of overhang on one side of the roof while rolling out a roofing sheet. Allow a few inches of overhang on the roof once again by chopping it.
- Ensure the roof is precisely flat and the flashing has a half-inch overhang. Then, roll the roof up halfway again with care.
- Wearing strong gloves and long sleeves, ignite the propane torch. When bubbles develop, roll the roofing material forward with your foot to complete the installation.
- Repeat with the subsequent sheet, aligning it so that it overlaps the first sheet by a few inches.
- To establish a firm seal, press the seam between the two sheets with your foot and gloved hand. Along the seam, molten asphalt should seep out.
- Continue for the remainder of the roof.
Peel-and-stick roofing is more suitable for the DYI project because there is no risk of fire and no fumes to deal with. Commence the operation following step 5.
- Remove the adhesive film and reattach the roofing with care. Before bonding the material permanently to your flat roof, smooth it out. Continue this technique over the whole length of your roof, leaving a minimum overlap of six inches.
- Roll the entire roof surface using a weighted roller, taking particular attention to the overlap.
- Seal the edges of the modified bitumen roofing using roofing cement and roll the sheets tightly to seal the layers together.
modified bitumen roof system
Modified bitumen is known by several different names, including polymer-modified bitumen and rubberized asphalt. This material is commonly referred to as "mod bit" in the roofing industry. Modified bitumen is "modified" during the manufacturing process when a polymer (a synthetic rubber or plastic) is combined with the asphalt. This is how modified bitumen gets its name. Although the term "bitumen" can technically refer to either asphalt or coal tar pitch, "bitumen" means "roofing asphalt" in Europe, where modified bitumen was first developed and adopted. The production of mod bits does not require the use of coal tar pitch. Asphalt is used to make modified bitumen roofing material. It is compatible with other asphalt-based roofing products such as asphalt roofing cement, mastic, asphalt cutback, asphalt coatings, and so on. Because there is such a wide variety of user-friendly asphalt roofing products, this material has an advantage over many other types of roofing in terms of how easily it can be maintained and repaired. 
Mod bit is made by combining raw asphalt with polymeric additives like synthetic rubber or plastic, which improve the asphalt's resistance to wear and tear as well as its strength and pliability. The amount of polymer additive included in the finished product can range from 3% to 15%, depending on the manufacturer and the type of product made. Modified bit maintains a more consistent level of strength and flexibility across a wider temperature range than unmodified asphalt, which is typically used for built-up roofs. During the manufacturing process, sheets of modified bitumen roofing are produced. Layers of modified asphalt are placed on top of a reinforcement fabric in these sheets. The reinforcement part is made from either fiberglass or polyester, or a combination of the two. The finished mod bit sheets are typically sold in rolls and have a width of about 39 inches (one meter). The length of the rolls is typically between 10 and 25 meters, or 25 and 33 feet. 
modified bitumen vs roll roofing
Customers can now select from a wide range of roofing materials and styles. However, there are some types of roofing that are superior to others. Roll roofing and modified bitumen are two of the most common and widely used types of roofing material on the market today. These two roofing styles are very different from one another, but either one would be an excellent choice for your home's roofing. When it comes to endurance and durability, modified bitumen roofing materials outperform asphalt roll roofing materials. The fact that modified bitumen is long-lasting and can last between 20 and 30 years is the most significant advantage it provides. 
However, one disadvantage is that it is more difficult to install and repair, which results in higher labor costs. As a result, some roofing contractors avoid using products containing modified bitumen. Both roll roofing and modified bitumen are viable options for your roof, and each has advantages. Despite the fact that rolled roofing and modified bitumen are similar in many ways, there are some distinctions between the two types of roofing. If you want to save money, do your own roof installation, or finish your roofing project quickly and easily, rolled roofing is the way to go. However, if you want a long-lasting roof that is resistant to severe weather, you should avoid rolled roofing because it lacks the necessary characteristics. Modified bitumen roofing is a good choice if you want a long-lasting roof that is resistant to damage from severe weather. This material is extremely durable. However, if you want to save money, install your roof yourself, or finish your roofing project quickly and easily, you should not choose modified bitumen roofing.
3 ply modified bitumen roof
Built-up roofing membranes are a popular choice for roof repairs and new construction. A 3-Ply Hybrid BUR membrane is distinguished from other membrane options by its combination of a 1-ply base sheet and two plies of glass felt, which improves membrane performance while reducing the weight of the roofing system. Although this membrane is not a one-size-fits-all solution, a 3-ply roofing system may be an excellent choice for building owners looking for a quick installation period. Here are some of the benefits of 3-ply roofing: There is no flame: A three-ply hybrid system can be installed at any temperature. This means that installations with no or low flame are possible. This is extremely useful when the fire is a concern for the building or structure in question. 
Low Odor Asphalt: When installing a three-ply hybrid BUR membrane, low-odor asphalt is an option. Low-odor asphalt is frequently used in buildings where odor is an issue, or when repairs or replacements are being performed while the facility is still operational. When time is of the essence, 3-ply systems can be installed quickly due to the combination of one SBS base sheet and two plies of glass felt. It is possible to install a waterproof single-ply base sheet. Due to changing weather patterns and other factors, the two layers of glass felt may be added later if necessary. Class A Fire Rating: The use of aggregate cover results in an assembly with a Class A fire rating, which exceeds the building code's Class C fire rating requirements. If your facility is at risk of fire, this could lower your insurance rates and give you peace of mind. Make sure to keep in touch with our professional sales executive for more information.
