Understanding Flat Roof Systems

Flat roofs are a popular choice for commercial buildings and modern residential homes in Denver. Unlike pitched or hip roofs, flat roofs offer usable space for solar panels, HVAC systems, or even a garden deck. But they also require proper waterproofing, drainage, and insulation.

Let’s break down the three most common flat roofing systems.

Built-Up Roofing (BUR)

BUR systems are one of the oldest and most reliable forms of flat roofing. They're made of layers of tar paper, bitumen, gravel, and fiberglass.

Advantages of Built-Up Roofs

• Known for long lifespan and durability

• Great waterproofing protection

• Resistant to ultraviolet rays and foot traffic

Drawbacks of Built-Up Roofs

• Heavier weight adds stress to your building

• Takes longer to install compared to other systems

• Usually higher upfront cost

Modified Bitumen Roofing (MBR)

Modified Bitumen is a flexible, asphalt-based system reinforced with polymer layers like styrene-butadiene-styrene (SBS) or atactic polypropylene (APP).

Advantages of Modified Bitumen Roofing

• Performs well in extreme heat and cold

• Easy to install with torch or self-adhering methods

• Good elasticity and flexibility

Drawbacks of Modified Bitumen Roofs

• Can scuff or tear under heavy foot traffic

• May have a shorter life expectancy than other options

Rubber Membrane Roofing (EPDM)

EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane known for its cost-effectiveness and flexibility.

Advantages of EPDM Roofing

• Lightweight and easier to install

• Resistant to ozone, hail, and UV rays

• Long-lasting with proper maintenance

Drawbacks of EPDM Roofs

• Seams can leak if not properly sealed

• Vulnerable to punctures from debris or tools

Comparing Flat Roof Costs

Wondering how much flat roofing in Denver costs? Here's a general breakdown:

• EPDM Rubber: $4–$8 per square foot

• Modified Bitumen: $5–$10 per square foot

• Built-Up (BUR): $6–$12 per square foot

These prices can vary based on roof size, materials, insulation, drainage design, and local labor rates. We offer competitive rates and will always work with your budget.

Lifespan and Warranty Considerations for Flat Roofs

Each roofing system has its own expected life:

• BUR: 20–30 years

• Modified Bitumen: 15–25 years

• EPDM: 20–30 years

Maintenance Requirements for Different Flat Roof Types

Routine flat roof maintenance helps prevent bigger issues down the road.
Here’s how to keep yours in good shape:

BUR Maintenance

• Check for cracks in bitumen or bald spots in gravel coat

• Inspect rain gutters and drains to prevent water pooling

Modified Bitumen Maintenance

• Watch for worn areas, especially around seams and flashing

• Clean off debris like sticks or gravel buildup

EPDM Maintenance

• Clear off leaves and snow to prevent moisture

• Check seams and edges for signs of adhesion issues
