Whether you are a homeowner or a contractor, this article will serve as a valuable resource to help you make informed decisions when it comes to built-up roofs. So, let's dive into the world of built-up roofs and discover why they are a top choice for flat roofing. Welcome to our guide on built-up roofs! Whether you're looking for a roofing contractor, researching materials, or seeking information on specific types of roofs, we've got you covered. In this article, we'll cover everything you need to know about built-up roofs and why they may be the right choice for your roofing needs. Built-up roofs, also known as BURs, are one of the oldest and most traditional forms of roofing.
They consist of multiple layers of roofing felt, bitumen, and a top layer of gravel or mineral cap sheets. This creates a strong and durable roof that can withstand harsh weather conditions. One of the main differences between built-up roofs and other roofing materials is their composition. Built-up roofs are made up of several layers, which contribute to their strength and durability.
On the other hand, single-ply roofing systems are made up of only one layer, making them less durable than built-up roofs. Built-up roofs also have the advantage of being fire-resistant. The multiple layers of bitumen and gravel or mineral cap sheets provide a barrier against fire, making them a safer choice for your home or building. Additionally, built-up roofs have excellent insulation properties, helping to regulate temperature and reduce energy costs. Another benefit of built-up roofs is their versatility in terms of installation. They can be installed on flat or low-sloped roofs, making them a popular choice for commercial buildings.
They can also be customized to fit the specific needs and requirements of different structures. In conclusion, built-up roofs are a reliable and durable roofing option that has stood the test of time. Their multiple layers, fire-resistant properties, and insulation benefits make them a popular choice for both residential and commercial buildings. We hope this guide has provided you with valuable information on built-up roofs and helped you understand why they may be the right choice for your roofing needs.
Installation Process
When it comes to installing a built-up roof, the process can vary depending on the specific type of built-up roof being installed. However, there are some general steps that are typically followed in the installation process. The first step is to prepare the roof surface by cleaning and removing any debris or old roofing materials.This is important in order to ensure a smooth and stable surface for the new built-up roof. Next, a base layer of insulation is usually installed to provide added protection and insulation for the building. This can help improve energy efficiency and reduce heating and cooling costs. After the insulation, layers of roofing felt are applied using hot asphalt or other adhesive materials. These layers are then topped with a layer of gravel or mineral surfacing to help protect against UV rays and provide additional waterproofing. The final step is to install the cap sheet, which is typically made of a waterproof material such as modified bitumen or EPDM rubber. This layer serves as the topmost layer of the built-up roof and provides the final layer of protection against the elements. Overall, the installation process for a built-up roof can be time-consuming and labor-intensive, but the end result is a durable and long-lasting roofing system that can provide excellent protection for your building.
Cost Considerations
When considering a new roof for your home or building, one of the most important factors to take into account is cost.After all, your roof is a major investment and you want to make sure you are getting the best value for your money. So, how does a built-up roof stack up when it comes to cost?Compared to other roofing materials, built-up roofs can be a cost-effective option. While prices can vary depending on factors such as location and the size of the roof, built-up roofs are generally less expensive than materials like metal or tile. This is because built-up roofs use layers of tar and gravel or asphalt and felt to create a durable and waterproof surface, rather than more expensive materials. Another advantage of built-up roofs is that they have a longer lifespan compared to some other roofing materials.
This means that while the initial cost may be slightly higher than other options, you will save money in the long run by not having to replace your roof as often. It is important to keep in mind that while built-up roofs may be more affordable compared to other materials, the cost can still vary significantly depending on factors such as the size of the roof, the number of layers needed, and the type of materials used. It is always best to consult with a roofing professional to get an accurate estimate for your specific project.
Benefits of Built-Up Roofs
A built-up roof, also known as a BUR, is a popular roofing option for flat or low-sloped roofs. It is made up of multiple layers of materials such as felt, asphalt, and gravel or other aggregates. These layers are fused together to create a durable and long-lasting roofing system. So, why should you consider a built-up roof for your next roofing project? Here are some of the main benefits:- Durability: Built-up roofs are known for their durability and can last up to 25 years with proper maintenance.
The multiple layers provide added strength and protection against harsh weather conditions.
- Waterproofing: The layers of materials used in built-up roofs create a waterproof barrier, making it an ideal choice for flat roofs that are prone to water pooling.
- Cost-effective: Due to its long lifespan and low maintenance costs, a built-up roof can be a cost-effective option in the long run.
- Fire-resistant: The layers of asphalt used in built-up roofs make them highly fire-resistant, adding an extra layer of safety to your property.
Maintenance and Repair
Built-up roofs are known for their durability and longevity, but like any roofing material, they still require regular maintenance and occasional repairs to ensure their optimal performance. Here are some key maintenance and repair considerations to keep in mind:Inspections: Regular inspections are crucial for catching any potential issues with your built-up roof before they become major problems.These inspections should be done at least twice a year by a professional roofing contractor.
Cleaning:
Built-up roofs should be cleaned at least once a year to remove any debris, dirt, or algae that may have accumulated. This not only keeps your roof looking clean and well-maintained, but it also helps prevent any potential damage from occurring.Repairs:
If any damage is found during an inspection or cleaning, it is important to address it promptly to prevent further damage. This may include patching up small holes or tears, resealing seams, or replacing damaged layers of the roof.Drainage Maintenance:
Proper drainage is essential for built-up roofs, as standing water can cause damage over time. Regular maintenance of gutters, downspouts, and other drainage systems is necessary to ensure proper water flow off the roof. By following these maintenance and repair practices, you can prolong the lifespan of your built-up roof and keep it functioning at its best.Remember to always consult a professional roofing contractor for any major repairs or concerns about your built-up roof.
Types of Built-Up Roofs
Built-up roofs, also known as BUR, are a popular choice for flat roofs due to their durability and longevity. This type of roof is made up of multiple layers of bitumen and reinforcing fabrics, such as fiberglass or organic mats. The top layer is then coated with a layer of gravel or mineral granules to protect against UV rays and provide additional insulation. There are three main types of built-up roofs: asphalt, coal tar, and cold-applied adhesive. Each type offers its own unique benefits and is suitable for different environments and budgets.Asphalt Built-Up Roof
The most common type of built-up roof is the asphalt BUR.It is made up of layers of hot or cold-applied asphalt and reinforcing fabrics. This type of roof is known for its flexibility and ability to withstand extreme temperatures. It is also relatively inexpensive compared to other types of built-up roofs.
Coal Tar Built-Up Roof
A coal tar BUR is made up of layers of coal tar and reinforcing fabrics. This type of roof is known for its resistance to water and chemicals, making it a popular choice for industrial buildings.It also has a longer lifespan compared to asphalt BURs but can be more expensive.
Cold-Applied Adhesive Built-Up Roof
As the name suggests, this type of built-up roof is installed using cold-applied adhesives rather than hot asphalt or coal tar. It is a more environmentally-friendly option as it does not require the use of heat during installation. However, it may not be as durable as other types of built-up roofs. In conclusion, built-up roofs are a reliable and cost-effective option for both residential and commercial properties. With their long lifespan, durability, and fire resistance, they are a popular choice among roofing contractors and property owners.If you're in need of roofing services, consider a built-up roof for your next project.
