Residential vs. Commercial Roofing: What’s the Difference?

Helping Oklahomans Choose the Right Roof for Every Property

When it comes to roofing, one size definitely does not fit all. A roof that works well for a home may not be the right fit for a business property, and vice versa. At Statewide Roofing, we’ve been serving both homeowners and business owners across Oklahoma for decades, and one of the most common questions we hear is: “What’s the difference between residential and commercial roofing?”

Understanding these differences can help you make informed decisions, whether you’re replacing a roof on your home, repairing storm damage on your business, or exploring roofing options for new construction. In this guide, we’ll break down the major differences between residential and commercial roofing so you know what to expect when it’s time to invest in your property.

Design and Structure

Residential Roofing

Most residential roofs are pitched (sloped), which allows rain and snow to run off easily. Asphalt shingles are the most common material, but homeowners also have the option to choose from metal, tile, or wood shingles, depending on their style preferences and budget. Residential roofs are designed not only for protection but also for curb appeal; they’re a visible part of your home’s character.

Commercial Roofing

Commercial roofs, on the other hand, are usually flat or have a very low slope. This design facilitates the installation of HVAC systems, solar panels, or other equipment. Due to their large surface area, commercial roofs are typically designed with durability and functionality in mind, rather than aesthetics. Materials like TPO, EPDM, and modified bitumen are most commonly used because they withstand heavy use and exposure well.

Materials Used

Residential Roofing

• Asphalt shingles: Affordable, versatile, and widely used.
• Metal roofing: Long-lasting and energy efficient.
• Clay or concrete tiles: Durable yet heavier, often featured in specific architectural styles.
• Wood shakes: Attractive and natural, but require more maintenance.

‍Commercial Roofing

• TPO (Thermoplastic Polyolefin): Popular for energy efficiency and cost-effectiveness.
• EPDM (Ethylene Propylene Diene Monomer): A synthetic rubber membrane with excellent durability.
• Modified Bitumen: Known for weather resistance and flexibility.
• Metal Panels: Common in warehouses and industrial buildings for strength and longevity.

Installation Methods

Residential Roofing

Residential roofs are generally smaller and quicker to install. Depending on size and materials, many residential roofing projects can be completed in just a few days. Installation usually involves layering shingles or panels over underlayment and decking.

Commercial Roofing

Commercial roof installation is often more complex due to size and design. Flat roofs require careful attention to drainage, insulation, and sealing to prevent leaks and maintain their integrity. Depending on the materials, the process may involve adhesives, heat welding, or multi-layer systems, making installation more time-intensive.

Maintenance and Lifespan

Residential Roofing

Residential roofs require regular inspections, particularly after severe weather events. Shingle replacement, gutter cleaning, and minor repairs are the most common maintenance tasks. Lifespans vary by material: asphalt shingles may last 20–30 years, while metal or tile can last much longer with proper care.

Commercial Roofing

Due to their flat design, commercial roofs necessitate more frequent inspections and maintenance. Water pooling, punctures, and membrane damage are common concerns. With consistent maintenance, many commercial roofing systems can last 20–40 years, depending on the material used.

Storm Damage Considerations

Living in Oklahoma, storm preparedness is critical for both residential and commercial roofs. High winds, hail, and heavy rain can cause severe damage regardless of the roofing system. 

However, the types of damage often differ:

• Residential roofs: Missing shingles, leaks in the attic, or cracked tiles.
• Commercial roofs: Membrane punctures, pooling water, or damage to rooftop equipment.
