The roof is essential to a building’s exterior. While all roofing systems serve the same purpose, metal roofs stand out from the rest. They are more durable and cost-efficient, which makes them suitable for residential and commercial properties. Although these roofing options may look similar, there are distinct differences between the two. 

From roof design to material choices, commercial and residential metal roofs are different in several aspects. Whether you’re a homeowner or a business owner, this blog post will help you make an informed decision for your next roofing project.

The Design

One of the main distinctions between residential and commercial metal roofing is the design. Metal roofs used for homes often mimic the appearance of roof shingles and tiles. In addition, residential metal roofs are available in a variety of colors. From shades of gray to brown, you can find your desired color that matches the aesthetic of your neighborhood. 

On the other hand, commercial metal roofs tend to have a more sleek and modern appearance. Metal panels used in commercial buildings are larger in square footage. They are also compatible with most roof accessories like ventilation systems, skylights, and blowers. Some businesses have solar panels installed on their metal roofs. This is a smart investment for business owners looking to generate excess electricity and reduce their energy costs.

The Slope

Also known as pitch, the slope refers to the angle of the roof surface above the horizontal plane. Residential homes typically have pitched roofs to help redirect rainwater off the roof. In general, a steep slope allows efficient shedding and better attic ventilation. This style of the metal roof also gives you more attic space for storage purposes.

The slope of commercial metal roofs is quite different from residential ones. Commercial roofs are considered low-slope roofing. They often have nearly flat slopes, which helps maximize the space and functionality of the building. Due to its flat roof design, HVAC units and solar panels can be easily installed at the top of the metal roof. 


Another difference between a commercial and residential metal roof is the installation process. Roof installations in offices and warehouses are significantly different from residential homes. Depending on the size of the property, residential roof installation can be done within days to one week. 

In contrast, a commercial metal roof may take at least one month to erect. Due to its size and complex design, a commercial roof is a huge undertaking. It requires more materials and much extensive labor. Commercial buildings need to undergo strict building codes, which can lead to a more complex installation process. 


Due to the amount of labor and materials needed, commercial metal roofs tend to be more expensive than residential ones. You can expect a higher overall cost when tackling a commercial roofing project. Before you start any work, request quotes from various roofing contractors to see which one fits your budget.

Whether it’s for commercial or domestic purposes, here are several factors that can affect the cost of metal roofing:

  • Location
  • Size of the Roof
  • Roof Pitch
  • Type of Metal Used
  • The Complexity of the Design
  • Roof Accessories and Add-On Features


Commercial and residential buildings have varying roof maintenance requirements. Since office buildings and commercial centers cover larger square footage, they require more upkeep. Commercial metal roofs need a scheduled inspection at least every six months. Doing so will prevent roof issues from getting worse. Any damage to the roof can potentially affect the operation of the business.

On the contrary, houses with metal roofs only require inspections once or twice a year. Residential metal roofs only need minimal cleaning and maintenance. They are easier to maintain because they’re smaller in size. Since inspections are not extensive, homeowners can definitely save more money on roof repairs and maintenance.
