Flat Roof (Built-Up Roof) Replacement

At GreenGo Roofing, we specialize in high-quality, energy-efficient flat roof replacements designed to protect your property while maximizing energy efficiency. Built-up roofing (BUR) is one of the most reliable and long-lasting flat roofing systems, commonly used for both residential and commercial buildings. However, like any roofing system, BURs require replacement over time due to wear and tear, water damage, and aging materials.

Understanding Built-Up Roofing (BUR)

What Is a Built-Up Roof (BUR)?

A built-up roof (BUR) is a layered roofing system composed of asphalt, tar, gravel, and reinforcing materials. It’s one of the oldest and most reliable flat roofing methods, offering excellent protection against weather elements, UV rays, and water damage.

Key Benefits of a Built-Up Roof

  • Durability: BUR systems are known for their long lifespan, typically lasting 20 to 30 years or more with proper maintenance.
  • Waterproofing: The multiple layers enhance waterproofing, reducing the risk of leaks and water damage.
  • Energy Efficiency: Reflective coatings help reduce energy costs by reflecting sunlight and reducing heat absorption.
  • Fire Resistance: The reflective coatings add a layer of fire resistance, enhancing the overall safety of your property.

Layers of a BUR System

A well-constructed BUR consists of several layers, each playing a crucial role in its durability and efficiency:

  1. Base Layer
  • Installed directly over the roof deck for structural support and insulation.
  • Enhances the stability and energy efficiency of the roofing system.
  1. Multiple Ply Layers
  • Composed of roofing felt or fiberglass sheets alternated with layers of bitumen.
  • Adds strength and durability, enhancing resistance to harsh weather conditions.
  1. Asphalt or Bitumen Layer
  • Acts as a waterproofing agent, sealing the roof from moisture infiltration.
  • Applied using hot-mopped asphalt, cold-applied adhesives, or coal tar pitch.
  1. Emulsion, Primer, and Highly-Reflective Coatings
  • Release any trapped gases from the newly built roof and allow reflective coatings to cure properly.
  • These coatings provide UV protection to help prevent damage to the new roof.
  • Shields the roof from UV damage, physical wear, and fire hazards.
  • Improves energy efficiency by reflecting sunlight and reducing heat absorption.

Signs You Need a Built-Up Roof Replacement

A deteriorating BUR roof can lead to severe structural damage if not addressed promptly. Watch for these key warning signs:

  1. Persistent Leaks and Water Damage
  • Water stains on ceilings or walls indicate a failing BUR system.
  • Ignoring leaks can lead to significant structural damage and costly repairs.
  1. Blistering, Cracking, or Bubbling of the Roof Surface
  • Extreme temperature changes cause roof materials to expand and contract, leading to cracks, blisters, and bubbling.
  • These defects compromise the roof’s waterproofing and overall durability.
  1. Ponding Water Issues
  • Standing water on your flat roof for more than 48 hours can weaken materials, cause leaks, and result in structural damage.
  • Effective drainage solutions are crucial to prevent ponding water problems.
  1. Increased Energy Bills Due to Poor Insulation
  • A deteriorating BUR system leads to poor insulation, making your HVAC system work harder and increasing energy costs.
  • Replacing your BUR roof restores energy efficiency and reduces utility expenses.
  1. Roof Aging and Wear Over Time
  • If your built-up roof is over 20-30 years old, it’s likely reaching the end of its lifespan.
  • Proactively replacing an aging BUR system prevents significant damage and costly repairs.
