Introduction
Navigating commercial roofing can seem overwhelming. There are many options and things to think about. Choosing the right roofing system is very important. It helps to keep your building strong and lasting. In Mobile, AL, built-up roofing is a popular choice among businesses. This article by Commercial Roofing Mobile AL will take a closer look at built-up roofing systems. We will discuss what they are made of, how they are installed, their benefits, drawbacks, and how they compare to other commercial roofing options.
Understanding Built-Up Roofing Systems
Built-up roofing, or BUR for short, has been around since the 19th century. It shows how effective some roofing ideas can be. BUR roofs are made with multiple layers of asphalt, which makes them strong and good at resisting weather.
These roofs are ideal for low-slope or flat roofs. They give a reliable shield against rain and snow. Unlike roofs with a steep pitch that easily let water flow off, flat roofs need a strong roofing option to stop water from collecting and causing leaks. The multi-layer design of BUR systems really helps in this situation.
Key Components and Their Functions
A built-up roofing system is designed for strong performance with its many layers. Each layer has its own job and helps make the system sturdy. Let's look at these important parts:
The base sheet is usually made of fiberglass. It acts like a strong foundation and is the first line of defense against moisture. It provides a steady base for the other layers. It is important for the base sheet to stick well to the roof deck. This helps prevent any weak spots in the system.
Next, we have the layers of bitumen, which are usually made of hot asphalt. Bitumen is the main waterproofing material. It forms a seamless barrier that stops water from getting through. This process involves putting on several layers, with each one placed with care to make sure that everything seals tightly.
Finally, there is the top layer or cap sheet. This layer may be made of gravel or other materials with a mineral surface, including a cover board layer of asphalt. It protects against UV rays, foot traffic, and severe weather conditions. This final touch helps ensure the durability and effectiveness of the whole BUR system.
The Installation Process of Built-Up Roofing
The installation of a built-up roof is a detailed job that needs careful attention to techniques and safety rules.
It starts with a complete check of the roof deck. Workers remove any debris or bumps to create a smooth and sturdy base for the roofing system. When the roof deck is ready, the installation process begins with the careful putting down of the base sheet. This layer is very important because it sets up the other layers and affects how well the roofing system works.
Next, hot asphalt is added, which creates the waterproof layer that is the key feature of BUR systems. This part needs careful skill, as the hot asphalt must be spread out evenly and allowed to cool and cure correctly. If proper steps are not followed, it can weaken the membrane and cause leaks.
Major Advantages of Built-Up Roofing in Mobile AL
Built-up roofing is a popular choice in Mobile, AL. It is favored because it offers many benefits that suit the local climate and building needs. The unique features of BUR systems contribute to these advantages.
Mobile, AL has warm temperatures and sometimes heavy rain. This weather requires a roofing system that can handle these conditions. Built-up roofing meets these needs, making it a good investment for building owners.
Durability and Longevity
One reason built-up roofing is so popular is its great durability. This roofing system is made to last a long time, giving reliable performance for many years.
The strength of a BUR system comes from its layered design. It uses strong materials like bitumen and special fabrics. This helps the roof endure various weather and time challenges. The top layer, often made of gravel or another mineral surface, boosts the durability of the BUR system even more.
When you compare BUR to other roofing options like modified bitumen or single-ply membranes, BUR usually lasts longer. While those other systems can be more flexible, they don't match the strength and long life that built-up roofing offers. This makes BUR a smart choice for building owners who want to reduce maintenance costs and interruptions over time.
Superior Resistance to Water and Weather
Mobile, AL has a climate with heavy rain and high humidity. This makes it important to have a roofing system that resists water very well. Built-up roofing (BUR) is a great choice for this, providing strong protection against water intrusion.
The roof has several layers of bitumen. These layers are put on carefully during the installation process. They work together as a strong barrier against water penetration. If one layer gets a little worn or damaged, the layers underneath still keep out leaks.
Besides being water-resistant, BUR systems are ready for the other problems that come with the climate in Mobile, AL. The reflective coating on the top layer of a BUR system helps to bounce harmful UV rays away. This keeps the building cooler. It also helps save energy because HVAC systems don't have to work as hard, which means lower energy costs.
Common Challenges with Built-Up Roofing Systems
Built-up roofing has many benefits, but it's important to know its possible downsides too. Like other roofing systems, BUR has some things to consider.
Still, it’s crucial to look at these challenges from both sides. Many problems linked to BUR can be reduced or even stopped with smart actions and quick help from skilled roofing experts.
Potential for Blisters and Splitting
One main worry with BUR roofing is the risk of blistering and splitting as the system gets older or wears down.
Blistering can happen when moisture gets trapped between the BUR layers. This may be due to several reasons, like not enough ventilation in the roof deck, bad installation practices, or damage to the roofing membrane that lets water in. When temperatures change, the moisture trapped inside expands and contracts. This causes noticeable blisters on the surface of the roof. While these blisters might look bad, they can harm the system’s strength if not fixed.
Besides blisters, BUR roofing can also develop splitting or cracking over time. This often happens because of extreme temperatures, especially in places like Mobile, AL, where the sun can really heat things up. The ongoing expansion and contraction of the roofing materials, along with UV exposure, can slowly damage them, which leads to cracks or splits.
Maintenance Requirements
Keeping a built-up roofing system in good shape depends on regular maintenance.
BUR is well-known for lasting long, but skipping inspections and care can cause quick damage. This could lead to expensive repairs later. How often you should check your roof can change. It depends on how old the roof is, the weather it faces, and the overall state of the roofing materials.
A vital part of BUR maintenance is to keep the roof surface clear of debris. Things like leaves and branches can trap water, block drainage, and invite pests. Regularly sweeping or blowing off the roof helps prevent these problems, making the BUR system last longer. Also, look carefully at spots where the roofing membrane has vents, pipes, or other fixtures going through it.
Comparing Built-Up Roofing to Other Commercial Roofing Options
When choosing the best roofing system for a commercial building, it's important to look at the pros and cons of different options, including commercial roofing systems. Built-up roofing has been around for a long time and is often compared to newer choices available today.
By knowing the details of each option, building owners can make smart decisions that fit their budget, how long they want it to last, and what it should look like.
Built-Up Roofing vs. Single-Ply Membranes
Single-ply membranes, especially those made from materials like TPO (thermoplastic polyolefin) and ply sheet options, are becoming popular in commercial roofing. They are lightweight and energy-efficient compared to traditional BUR systems, often costing less per square foot. However, there are some downsides.
One main reason building owners like single-ply membranes is their ease of application. Installing them is quicker and requires less skilled labor than the multi-layer process of BUR. This means lower installation costs, which makes single-ply a good choice for some building owners.
Still, the simpler design of single-ply membranes, while great for installation, can make them more vulnerable. | Feature | Built-Up Roofing | Single-Ply Membrane | |---|---|---| | Durability | Extremely Durable | Moderately Durable | | Installation | Labor-intensive | Easier to Install | | Lifespan | 20-30 Years | 15-25 Years | | Cost | Lower | Higher |
Built-Up Roofing vs. Metal Roofing Systems
Metal roofing is well-known for lasting a long time and looking good. It is a strong choice in the commercial roofing market. When you compare the pluses and minuses of metal roofs and built-up roofing, you find clear differences between these two common options.
Metal roofs are great because they resist fire, wind uplift, and impact damage. They are also very lightweight, which puts less pressure on a building's structure than the heavier, multi-layered BUR system. This lighter weight makes metal roofing a good option for updating older buildings. It adds less stress to the existing structure.
Still, one big drawback of metal roofing is the price. Metal roofing systems are usually more expensive at first. However, their long lifespan may help balance out this initial cost. Moreover, metal roofs often need special mechanical fasteners to hold them to the roof deck.
Conclusion
Built-up roofing systems are known for their strength and ability to resist harsh weather in Mobile, AL. While there can be issues like blistering, they last a long time and need little upkeep, making them a popular option. When compared to single-ply membranes and metal roofing, built-up roofing is more reliable. For the safety of your business property, think about the benefits of built-up roofing. If you are in Mobile, AL, check out quotes from experts to see the advantages yourself. Choose a roofing solution that offers lasting performance against tough environmental conditions.
