Modified Bitumen (mod bit)

MODIFIED BITUMEN ROOFING SYSTEMS

High-Strength, Multi-Layer Roofing Built for Durability & Long-Term Protection

Modified Bitumen (Mod Bit) roofing is one of the most robust and time-tested commercial roofing systems available. Designed for strength, flexibility, and impact resistance, Mod Bit is ideal for buildings that need maximum durability and multi-layer protection — especially in Colorado’s demanding climate.

L.E. Roofing has installed, repaired, and maintained Modified Bitumen systems across Colorado for more than 30 years, serving commercial, industrial, municipal, and government facilities. Our in-house crews and disciplined installation process ensure every Mod Bit system is engineered to withstand decades of performance, weather events, and operational demands.

If your building requires a tough, reinforced roofing system with proven reliability, Modified Bitumen offers unmatched value.

Why Choose Modified Bitumen for Your Commercial Roof?

Modified Bitumen is known for its durability, strength, and resilience under extreme weather conditions — making it a top choice for Colorado buildings.

Multi-Layer Strength & Redundancy

Unlike single-membrane systems, Mod Bit uses multiple reinforced layers, providing:

  • Increased puncture resistance

  • Superior impact protection

  • Longer lifespan

  • More stability under foot traffic

This makes it an excellent choice for roofs with frequent inspections, HVAC access, or heavy utility activity.

Excellent Performance in Colorado Weather

Modified Bitumen withstands:

  • Hail impact

  • Freeze–thaw cycles

  • High UV exposure

  • Wind uplift

  • Heavy rain & snow

It maintains flexibility in low temperatures and holds its structure during extreme heat — perfect for Colorado’s unpredictable climate.

Strong Waterproofing Capabilities

With heat-welded or cold-applied seams, Mod Bit offers excellent waterproofing performance for:

  • Low-slope roofs

  • Complex roof designs

  • Buildings with drainage challenges

Your building stays protected, even during intense storms.

Long-Term Value & Reliability

Modified Bitumen systems can last 20–30+ years with proper installation and maintenance, offering a strong ROI over the lifespan of the roof.

Our Modified Bitumen Roofing Installation Process

Commercial roofing requires more than material — it requires craftsmanship, engineering discipline, and proven installation methods.

Here’s how L.E. Roofing builds Modified Bitumen systems that last:

1. Roof Assessment & Design

We evaluate:

  • Structural conditions

  • Insulation needs

  • Drainage and slope

  • Penetration points

  • Existing membrane and substrate condition

Every system is custom-engineered for the building.

2. High-Performance Base Layers

A Mod Bit system typically begins with:

  • Base sheets

  • Vapor barriers (if needed)

  • Polyiso insulation

  • Coverboards (DensDeck/Securock)

These components create strength, fire resistance, and thermal stability.

3. Modified Bitumen Application

We install Mod Bit assemblies using:

  • SBS or APP-modified sheets

  • Heat-welded seams or cold-applied adhesives

  • Granulated or smooth surface cap sheets

The system is built layer by layer, providing redundancy and durability.

4. Detailing & Flashing Precision

Professional detailing protects the most vulnerable areas:

  • Parapet walls

  • Drains

  • Scuppers

  • HVAC curbs

  • Skylights

  • Pipes & penetrations

Our in-house metal fabrication ensures exact, watertight transitions.

5. Final QA Inspection

Before completion, your roof undergoes:

  • Seam inspection

  • Lift testing

  • Flashing verification

  • Drainage assessment

  • Perimeter fastening review

Every detail is checked — the L.E. Roofing way.
