The Ultimate Guide to BUR Roofing: What You Need to Know
When it comes to commercial and industrial roofing, durability, reliability, and cost-effectiveness are top priorities. One of the most trusted solutions for decades has been BUR roofing, or Built-Up Roofing. Known for its long lifespan, exceptional waterproofing, and ability to withstand harsh weather, BUR roofing is a go-to choice for property owners across Northeast Ohio, including Youngstown, Cleveland, Akron, and surrounding areas.
At S&K Construction and Remodeling LLC, we specialize in BUR roofing installation, repair, and maintenance. In this comprehensive guide, we’ll cover everything you need to know about BUR roofing, including its structure, benefits, drawbacks, installation process, costs, maintenance, and why it remains a preferred option for commercial buildings.
1. What Is BUR Roofing?
BUR (Built-Up Roofing) is a traditional roofing system that has been around for more than a century. Often called tar and gravel roofing, BUR is constructed from multiple layers of asphalt or coal tar alternated with ply sheets (typically felt). A layer of gravel or aggregate is applied on top to protect the roof from UV rays and weather damage.
How BUR Roofing Works
BUR roofing relies on the combination of layers to provide:
- Waterproofing: Asphalt layers create a seamless, watertight surface.
- Durability: Multiple plies increase resistance to punctures, wind, and heavy foot traffic.
- UV Protection: The gravel layer reflects sunlight, reducing roof degradation.
Where BUR Roofing Is Used
BUR roofing is ideal for low-slope commercial and industrial roofs, including:
- Warehouses
- Schools
- Hospitals
- Manufacturing facilities
- Retail centers
Its versatility and proven performance make it a staple in the commercial roofing industry.
2. Components of a BUR Roof
A typical BUR roof consists of several critical components:
- Roof Deck: The foundation of the roof, often made of concrete, metal, or plywood.
- Base Sheet: The first layer of felt applied directly to the deck.
- Asphalt Layers: Alternating layers of asphalt or coal tar provide waterproofing.
- Ply Sheets: Reinforcing fabrics placed between asphalt layers to add strength.
- Surfacing Material: Gravel or mineral granules protect the asphalt from UV rays, heat, and mechanical damage.
Some BUR roofs also include insulation layers beneath the base sheet to enhance energy efficiency.
3. Benefits of BUR Roofing
BUR roofing offers numerous advantages, making it a popular choice for commercial properties.
3.1 Exceptional Durability
With multiple layers of asphalt and ply sheets, BUR roofs are highly durable and resistant to punctures, heavy foot traffic, and structural stress. A properly maintained BUR roof can last 20–30 years, sometimes longer.
3.2 Waterproofing Excellence
The combination of asphalt and multiple plies creates a watertight barrier, protecting buildings from leaks and water damage even in heavy rain or snow.
3.3 Fire Resistance
BUR roofs are naturally fire-resistant, especially when using coal tar-based asphalt, providing extra safety for commercial buildings.
3.4 UV Protection
The gravel surfacing layer shields the roof from harmful UV rays, slowing the aging process of asphalt and preventing premature deterioration.
3.5 Low Maintenance
BUR roofs are relatively low maintenance compared to other commercial roofing systems. Periodic inspections and minor repairs are typically sufficient to keep the roof in excellent condition.
3.6 Energy Efficiency
Reflective gravel surfaces can help reduce cooling costs by reflecting sunlight and reducing heat absorption, which is particularly beneficial in hot climates.
4. Drawbacks of BUR Roofing
While BUR roofing has many advantages, there are a few considerations to keep in mind:
4.1 Weight
BUR roofing is heavier than other commercial roofing systems, such as single-ply membranes. Buildings must have a strong structural deck to support the additional weight.
4.2 Installation Complexity
Installing BUR roofing requires skilled professionals, as multiple layers must be applied correctly to ensure durability and waterproofing. Improper installation can lead to leaks and premature failure.
4.3 Limited Aesthetic Options
Because BUR roofs are covered with gravel or aggregate, there are fewer aesthetic options compared to metal or single-ply roofs. However, for industrial and commercial properties, functionality usually outweighs appearance.
4.4 Longer Installation Time
Applying multiple layers means installation can take longer than single-ply systems, which can be a factor for businesses needing a quick turnaround.
5. BUR Roofing vs. Other Commercial Roof Types
Comparing BUR roofing to other popular commercial roofing systems can help you determine if it’s the right choice for your building.
| Roof Type | Lifespan | Maintenance | Cost | Advantages |
|---|---|---|---|---|
| BUR Roofing | 20–30 years | Low | $5–$10 per sq. ft. | Durable, waterproof, fire-resistant, UV protection |
| Modified Bitumen | 15–20 years | Moderate | $6–$12 per sq. ft. | Flexible, easy to repair |
| TPO | 20–25 years | Low | $6–$12 per sq. ft. | Reflective, lightweight, energy-efficient |
| EPDM | 15–20 years | Low | $5–$10 per sq. ft. | Cost-effective, flexible, easy installation |
| Metal Roofing | 40–70 years | Low | $8–$20 per sq. ft. | Extremely durable, low maintenance, long lifespan |
BUR roofing is ideal for low-slope roofs requiring durability, fire resistance, and excellent waterproofing.
6. BUR Roofing Installation Process
Proper installation is crucial for BUR roof performance. At S&K Construction and Remodeling LLC, we follow industry best practices to ensure long-lasting results.
Step 1: Roof Deck Preparation
The roof deck must be clean, dry, and structurally sound. Any damage is repaired before installation.
Step 2: Apply Base Sheet
A base sheet of felt or fiberglass is attached to the deck, providing a foundation for asphalt layers.
Step 3: Apply Asphalt Layers
Alternating layers of hot or cold asphalt are applied. Asphalt acts as a waterproofing membrane.
Step 4: Add Ply Sheets
Ply sheets (reinforcing fabrics) are embedded between asphalt layers to strengthen the roof.
Step 5: Apply Surfacing Material
A layer of gravel, crushed stone, or mineral granules is embedded into the top asphalt layer to protect against UV rays, wind, and foot traffic.
Step 6: Inspection
A final inspection ensures all layers are properly installed, seams are sealed, and the roof is watertight.
7. BUR Roof Maintenance Tips
Maintaining your BUR roof can extend its lifespan and prevent costly repairs.
7.1 Schedule Regular Inspections
- Inspect your roof twice a year, ideally in spring and fall
- Check for cracks, blisters, leaks, and loose gravel
7.2 Keep the Roof Clean
- Remove debris, leaves, and dirt to prevent water pooling
- Ensure gutters and drains are clear
7.3 Address Damage Promptly
- Repair small leaks or cracks immediately
- Replenish gravel if it becomes thin or uneven
7.4 Maintain Flashing and Seals
- Check flashing around roof penetrations, edges, and skylights
- Reapply sealants as needed
7.5 Consider Preventative Maintenance Plans
- Many commercial roofing companies offer maintenance plans to prolong roof life and reduce emergency repair costs
8. Cost of BUR Roofing
The cost of a BUR roof depends on several factors, including roof size, number of plies, materials, and labor.
Average Costs per Square Foot:
- BUR Roofing: $5–$10 per sq. ft.
- Installation: $7–$12 per sq. ft. for multi-ply systems
- Maintenance: $200–$500 per year for inspections and minor repairs
Long-Term Value:
While BUR roofing may have higher upfront costs compared to EPDM or TPO, its durability and low maintenance make it a cost-effective choice over 20–30 years.
9. Signs Your BUR Roof Needs Repair or Replacement
Even the most durable BUR roof eventually needs attention. Look for these warning signs:
- Water leaks inside the building
- Blistering or bubbling asphalt layers
- Cracks or splits in the surface
- Missing or displaced gravel
- Excessive wear around roof penetrations and flashing
If you notice any of these issues, contact a professional commercial roofing contractor immediately to prevent further damage.
