What is the main difference between Commercial and Residential Roofing?

While all roofs have the same primary function of providing security and shelter, but they all are not the same! There are several different considerations, including construction, materials, maintenance, and installation, between commercial and residential roofs that make each one distinct. Slope, size, and complexity of work are the main variations between Commercial roofing and residential roofing.


In commercial and residential roofing, design is a significant distinction. Residential roofs, on the other hand, are typically built to suit a certain aesthetic, whereas commercial roofs are built to work. The majority of commercial roofs have a low slope or are almost flat. Furthermore, industrial roofs are much larger than residential roofs. Flat roofs maximize the use of interior rooms, making them a realistic choice for business owners. Additional features such as airflow mechanisms, smokestacks, exterior piping, and more can be incorporated into the construction of a commercial roof. The majority of residential roofs are pitched, which means they have a slope to them.


The materials used to cover your roof can be determined by the kind of roof you have. Here are a few options in the residential roof:

  • Asphalt Shingles
  • Wood Shakes and Shingles
  • Luxury Asphalt Shingles
  • Concrete Tile Roofing
  • Clay Tile Roofing
  • Copper Roofing

Because of their mid-to-high pitches, “classic” roofing materials like the ones mentioned above are commonly used for residential properties. Before adding any of the above alternatives on a residential roof, plywood is usually nailed to wooden rafters to build a secure underlayment.


Roofs, both industrial and domestic, need some maintenance. Commercial roofs are more difficult to maintain because of their flat surface and wide square feet. Flat roofs necessitate more repairs to maintain them in decent working order, as troublesome cracks can seep through if not properly maintained. Flat roof owners in places where there is a lot of rain and snow should inspect their roofs daily to avoid leakage. Fortunately, flat roofs are walkable, making inspections easy.

Unlike flat roofs, the slope on residential roofs allows rain, snow, and other debris to wash off and away from the structure.

Cost & Installation

The cost of a commercial roof is determined by the total square feet, the use of specialized machinery, safety devices, and materials, labor, and time. Such costs are factored into the price of a commercial roof, which is typically greater than a residential roof.

Since residential roofs are smaller, they are simpler to build and less expensive. Residential roofs will usually be completed in a few days.
