When it comes to commercial roofing, built-up roofing (BUR) is a popular choice due to its durability and longevity. However, as a property owner or manager, you may be wondering: how long will a built-up roof last? Get to know it with the biggest roofing company in the us.
The answer depends on a variety of factors. With proper installation and maintenance, a BUR can last anywhere from 20 to 40 years.
One of the main factors that affects the lifespan of a built-up roof is the number of layers, or plies, it has. Each layer can add approximately five years of life to the roof, but no system will have less than three layers.
Additionally, the quality of installation can impact the longevity of the roof. A well-installed BUR system can last up to 30 years, whereas a poorly installed one may only last 10 to 15 years.
It’s also important to note that regular maintenance and inspections can extend the lifespan of a built-up roof. Small issues, such as cracks or leaks, can be addressed before they turn into major problems that require a full roof replacement.
By keeping up with maintenance and addressing issues promptly, you can maximize the lifespan of your BUR and avoid costly repairs down the line.
Fundamentals of Built-Up Roofing
Composition and Types
Built-up roofing (BUR) is a type of roofing system that consists of multiple layers of reinforcing fabric, ply sheets, and bitumen. The layers are typically bonded together with hot asphalt or tar.
The top layer of the roof is usually covered with gravel or other types of aggregate to protect it from the sun and weather.
There are different types of built-up roofing systems, but the most common ones are the traditional and modified bitumen systems.
The traditional BUR system is made up of alternating layers of bitumen and reinforcing fabric. Meanwhile, the modified bitumen system uses a combination of asphalt and rubber modifiers to improve its performance.
Comparing Lifespans of Roofing Materials
When it comes to comparing the lifespans of roofing materials, built-up roofing systems are known to last longer than many other types of roofing materials.
For instance, asphalt shingles typically last between 15 and 30 years, while metal roofs can last up to 50 years.
Concrete and clay tiles can last up to 50 years as well, while slate and wood roofs can last up to 100 years.
Built-up roofing systems, on the other hand, can last up to 30 years or more, depending on the quality of installation and the number of layers (or plies) the roof has. Each layer can add approximately five years of life to the roof, but no system will have less than three layers.
Modified bitumen roofing systems can also last up to 30 years, while single-ply roofing systems such as TPO and EPDM can last up to 20 years.
However, the actual lifespan of a roofing system depends on various factors such as the quality of installation, maintenance, and weather conditions. See biggest roofing company in the us.
Maximizing the Longevity of a Built-Up Roof
To ensure that your built-up roof lasts as long as possible, there are a few key steps you can take. Proper installation and maintenance are crucial, as is recognizing and addressing common issues.
Proper Installation and Maintenance
The quality of installation is one of the most important factors in determining the longevity of your built-up roof. It is essential that you hire a reputable contractor who has experience with this type of roofing system.
Poor installation can lead to a host of problems, including leaks, blisters, and waves.
In addition to proper installation, regular maintenance is key to maximizing the lifespan of your built-up roof.
This includes regular cleaning to remove debris and dirt, as well as inspections to identify any potential issues before they become major problems.
You should also address any necessary repairs promptly to prevent further damage.
Recognizing and Addressing Common Issues
There are several common issues that can affect the lifespan of your built-up roof. These include blisters, cracks, and open joints. These issues can allow water to seep in and cause damage. UV rays and weather conditions can also take a toll on your roof, causing it to deteriorate over time.
To address these issues, have your roof inspected regularly by a professional. They can identify any potential problems and recommend the appropriate repairs. In addition, you may want to consider adding a reflective coating or surfacing materials to your roof to help protect it from the sun’s rays and extend its lifespan.
Proper ventilation and insulation are also important factors in maximizing the longevity of your built-up roof. Attic ventilation can help prevent ice dams and maintain proper temperature and moisture levels. Meanwhile, insulation can help improve energy efficiency and prevent heat loss.
While built-up roofs are known for their durability and longevity, they do require effective care and maintenance to ensure they last as long as possible. By following these tips and working with a reputable contractor, you can help extend the lifespan of your built-up roof and avoid the costs of a new roof for up to 40 years.
