Types of Commercial Roofs: A Guide for Business Owners

When it comes to commercial buildings, the type of roof you choose plays a critical role in energy efficiency, maintenance costs, and the longevity of your property. Understanding the different types of commercial roofs available can help you make a smart, long-term investment for your business.

In this guide, we’ll break down the most common commercial roofing systems, their benefits, and how to choose the best one for your needs.

1. Built-Up Roofing (BUR)

Best for: Flat or low-slope roofs

Overview: Built-up roofing, also known as “tar and gravel” roofing, consists of multiple layers of bitumen and reinforcing fabrics. The top layer typically features a gravel or reflective coating.

Pros:

• Durable and long-lasting
• Excellent UV and waterproof protection
• Low-maintenance

Cons:

• Heavy material requires strong structural support
• Longer installation time

2. Metal Roofing

Best for: Sloped or low-slope commercial buildings

Overview: Commercial metal roofs are typically made from galvanized steel, aluminum, copper, or zinc. They’re known for their strength and longevity.

Pros:

• Extremely durable (40+ years lifespan)
• Fire-resistant and recyclable
• Modern, clean look

Cons:

• Higher upfront cost
• Can be noisy without insulation

3. Modified Bitumen Roofing

Best for: Low-slope or flat roofs

Overview: Modified bitumen roofs are similar to BUR systems but use polymer-modified asphalt to improve flexibility and temperature resistance.

Pros:

• Easy to install and repair
• Good for extreme weather conditions
• Tear-resistant

Cons:

• Shorter lifespan compared to metal
• Can be prone to leaks if not installed properly

4. Thermoplastic (TPO) Roofing

Best for: Flat roofs needing energy efficiency

Overview: TPO (Thermoplastic Olefin) is a single-ply membrane roofing system that’s heat-welded at the seams and highly reflective.

Pros:

• Energy-efficient (reflects UV rays)
• Resistant to mold, tears, and dirt
• Environmentally friendly

Cons:

• Quality varies by manufacturer
• Needs proper installation for best results

5. PVC Roofing

Best for: Restaurants, factories, and commercial roofs exposed to chemicals or grease

Overview: PVC (Polyvinyl Chloride) is another single-ply roofing material similar to TPO, but with enhanced chemical resistance.

Pros:

• Strong chemical and fire resistance
• Long-lasting and low-maintenance
• Heat-welded seams for added durability

Cons:

• Higher material cost
• Can become brittle in cold climates over time

6. EPDM Roofing (Rubber Roof)

Best for: Budget-conscious flat roof projects

Overview: EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber roofing membrane known for its durability and ease of installation.

Pros:

• Affordable and lightweight
• UV and weather resistant
• Easy to maintain

Cons:

• Not as puncture-resistant as other options
• Typically black, which can absorb heat (white versions available)

Choosing the Right Commercial Roofing System

The best roofing solution depends on several factors:

• Your building’s structure and slope
• Local climate and weather conditions
• Energy efficiency goals
• Budget
• Desired lifespan and maintenance needs

A professional commercial roofing contractor can help assess your needs and recommend the most cost-effective and durable solution.
