Therefore, we’ve curated this detailed guide to navigate the expanse of commercial roofing systems, their types, and their unique advantages.

Types of Commercial Roofing Systems

1. Single Ply Roofing

Single ply roofing consists of a singular layer of thermosetting or thermoplastic material.

Given their flexibility and strength, they are a popular choice amongst the roofing companies in Columbia MD.

Benefits of Single Ply Roofing:

  • Durability: These systems are UV resistant and can withstand various environmental factors.
  • Installation: Their installation process, as mastered by Roofer Columbia MD experts like Kanga Roof, ensures swift project completion.
  • Energy Efficiency: Reflective materials in single ply roofing contribute to cooler roof surfaces and reduced energy expenses.

2. Built-Up Roofing (BUR)

Built-Up Roofing or BUR is one of the most time-tested roofing solutions. Comprising multiple layers of bitumen and reinforcing fabrics, BUR offers an unparalleled protection shield against leaks.

Benefits of Built-Up Roofing:

  • Longevity: With adequate maintenance, BUR systems can function optimally for over 20 years.
  • Versatility: They are apt for both low and steep slope roofs.
  • UV Protection: Gravel or mineral surfaces in the top layer ensure excellent UV protection.

3. Modified Bitumen Roofing

Modified Bitumen roofs involve reinforced roof fabrics as carriers for bitumen, making them a close kin to the BUR system.

Benefits of Modified Bitumen Roofing:

  • Flexibility: In colder climates, this roofing remains resistant to potential cracks and breaks.
  • Tear Resistance: These roofs are particularly durable against both foot traffic and punctures.
  • Ease of Repair: Kanga Roof, being one of the Roofing Companies in Columbia, emphasizes the ease of maintaining and repairing Modified Bitumen roofs.

4. Metal Roofing

Metal roofing systems, comprising materials like steel, aluminum, and copper, stand out for their durability and versatility.

Benefits of Metal Roofing:

  • Durability: They have a potential lifespan ranging between 40 to 70 years, based on the metal type.
  • Safety: Metal roofs are non-combustible, giving them a higher rank in fire resistance.
  • Energy Efficiency: These roofs reflect solar radiant heat, resulting in substantial cooling cost reductions.

5. Green Roofing

Green roofs are a testament to an eco-friendly commitment, characterized by vegetation growth on the roof surface.

Benefits of Green Roofing:

  • Temperature Control: Their insulating properties result in reduced energy consumption.
  • Improved Air Quality: The rooftop vegetation aids in filtering air pollutants.
  • Stormwater Management: By absorbing rainwater, green roofs play a significant role in reducing the stress on sewage systems.
