The Difference Between Residential and Commercial Roofing

February 15, 2023

Roofs play an equally important role in commercial and residential buildings – protecting people and objects. Even though the two share some basic similarities, residential and commercial roofing differ from each other in many ways. Design, materials, maintenance, and installation costs are some of the differences between the two types of roofing. In this article, we have compiled a list of the differences.

Roofing Material 

Durable material should be used regardless if it is for a commercial or residential roof. Material is chosen based on size, design, exposure to natural elements and other factors. Generally, commercial roofing materials are larger and heavier than residential roofing materials due to the larger roof size. 

For residential and commercial roofs, you can choose ceramic, wood shakes, solar shingles, and metal roofing. All these materials are durable and maximize the lifespan of the roof. However, to select the best one for your needs, you should consult a professional roofing contractor. 

Roofing Design 

Design is the main difference between the two roofing styles. Commercial buildings are much larger in square footage compared to residential properties. Therefore, commercial roofing is designed to cover the extensive area and size of the building. Commercial buildings require a stronger and sturdier roofing structure due to high foot traffic, equipment, and HVAC units.

Residential buildings often have gentler roof slopes, while commercial buildings may have flatter slopes to accommodate HVAC systems and large equipment. Residential buildings have pitched roofs with a higher slope that is easier to install. In conclusion, choosing the right roofing contractor is crucial so you do not end up with low-quality or wrong work.

Maintenance Requirements

Residential and commercial roofs require maintenance, but they often need different levels of attention. Maintenance of commercial roofing is more demanding. Regular inspections and preventative maintenance are necessary for commercial roofs rather than for residential roofs. Hire a professional roofing contractor for a commercial roofing inspection. Professional roofing contractors ensure that gutters and downspouts are clear and identify problems of all sizes before they grow into much bigger ones. 

As residential roofs are smaller and easier to inspect for damage, they are easier to maintain. A homeowner should conduct regular visual inspections from the ground, looking for wind-damaged or missing shingles, especially after a storm. Residential properties are small homeowners can replace broken shingles themselves and, if necessary, unblock the gutters. However, the best approach is to hire a professional roofing contractor for inspection and maintenance. 

Construction and Cost

Construction and the total cost is the most significant difference between the two roofings. Commercial roofing projects that are bigger and more complex cost more than residential ones. Unlike residential roofs, commercial roofs are usually bigger, have more access points, and require different materials and installation methods. 

As a result of the large size of a commercial roof and the specialized equipment and tools needed to install and maintain a safe, high-quality commercial roof, these are more expensive than residential roofs. Furthermore, commercial buildings are often subject to more stringent building codes and regulations, which can also increase costs.
