Difference Between Commercial and Residential Roofing

FLOYD MASON • Dec 22, 2021

While you may assume that a roof is just a roof, residential and commercial roofs have critical differences. They differ widely in material, design, maintenance, as well as in installation costs.

Differences in Commercial and Residential Roof Design

Think about the size of a commercial building. They are often much larger than a residential home in terms of square footage. This means that the commercial roofs are designed to support the size and extra weight of a commercial building. The roof design for a commercial roof also needs to take on the weight of equipment and the potential snow load. Commercial roofs are typically designed to have a low slope or are completely flat.

Residential homes do not have the same structural concerns and are typically designed with a pitched roof and a higher slope.

Materials Used for Commercial Roofs vs. Residential Roofs

When it comes to materials used for commercial and residential roofs, costs, appropriate product application, and life expectancy will all vary widely. Typically, commercial roofs and residential roofs need to be made from durable material to ensure they can handle the elements and other factors.

The materials also need to support the design. For example, if you plan to have AC and ventilation in your commercial building, the roof materials will need to be able to accommodate that. For a commercial roof, you can expect to see a flat or nearly flat roof membrane, asphalt shingles, or metal roof. Residential roofs have several material options and are steeper than commercial roofs.

At ACR1, we provide a monolithic roofing system , meaning it is one complete piece with no seams. This durable system is 3-4 times thicker than competitor materials and is flexible to the movement of the roofing structure to prevent damage. It also has highly reflective properties to lower energy costs. This durable material has no seams, so it is not prone to leaks like with traditional commercial roof materials.

Maintenance for Commercial Roofs vs. Residential Roofs

Since commercial roofs are larger than residential roofs, maintenance can be more extensive, and regular inspections are needed to prevent smaller issues from becoming major, more expensive problems. For commercial roofs, it is crucial to keep gutters clean at all times to prevent blockages. Depending on the roof material you have, the roof shingles or metal roofing can begin to disintegrate due to exposure to the elements, which is why regular inspections are critical to ensure it is in proper working order.

Residential roofs are not as extensive as commercial roofs, and since they are smaller in size, maintenance is far less complicated. It is easier to inspect residential roofs for damage, and in many cases, the homeowner can replace shingles or clean the gutters on their own, whereas a commercial roof will require the help of a professional roof contractor.

Commercial Roof Installation and Cost

Two major differences between commercial roofs and residential roofs are the installation and the cost of the roof. As mentioned earlier in the article, the size of the commercial roof plays a big role in the difference in design, materials, and maintenance when compared to a residential roof. The size of a commercial roof also affects the installation process and the cost of the commercial roof installation.

A residential roof is a more straightforward installation process that can be done by a local roofing contractor, whereas a commercial roof should be installed by experienced commercial roofing contractors at ACR1.

Prior to starting any work on your commercial roof, it is important to speak with the experts at ACR1 to ensure you are getting the best roofing system for your building at the best price. You can expect your commercial roof to be more expensive than a residential roof due to the amount of labor, type and amount of materials, size of the roof, and the protection equipment that is required for a successful commercial roof installation.

Commercial Roof Repairs and Replacement

Just like with the initial installation, a commercial roof replacement or repair will typically cost more than a residential roof replacement due to labor and materials. If your commercial roof has been damaged due to falling debris or harsh weather and has leaks, drafts, or standing water, you will need to have your roofing system repaired.

We can evaluate your commercial roof to see if repairs are possible or if a roof replacement is necessary to preserve the structural integrity of your building. We remain updated on all of the complexities of commercial roofing, offering you the latest roof replacement methods and technology.

Flat roofs can be a great choice for buildings due to their affordability and durability. However, if not done correctly, flat roofs are prone to water damage. Proper drainage is essential for the longevity of a flat roof, and selecting the correct drainage system is critical. Here we will discuss three common flat roof drainage systems - gutters, interior drains, and scuppers - as well as their pros and cons. Gutters Gutters are the most common form of flat roof drainage because they are low-cost and efficient when it comes to redirecting water off the roof. Gutters should be installed at a certain angle (approximately 1/4” per foot) to ensure proper water drainage. Gutters also need to be maintained over the years, as debris and leaves from storms or rain water can clog them up and create standing water. Pros: Low-cost installation and maintenance Easy to install Can direct water away from the foundation of the building Cons: Prone to clogging Requires periodic maintenance and cleaning Overflow from rain storms can cause damage to surrounding areas Interior Drains Interior drains are often seen as the higher-cost alternative to gutters. They are installed directly into the flat roof’s membrane and include a network of pipes that drain water off the roof into a downspout. Pros: Low maintenance More reliable than gutters in terms of preventing roofing damage Can be adjusted to fit any size of flat roof Cons: Expensive installation and maintenance costs compared to gutters May require frequent adjustments depending on the environment surrounding the building Can be difficult to install if the roof does not have the right slope Scuppers Scuppers are metal or plastic openings that allow water to drain off flat roofs. They generally come in square or rectangular shapes and are installed along the perimeter of a roof. The size and shape of scuppers should be adjusted accordingly in order to prevent water from overflowing onto the sides of a building. Pros: Easy and cost-effective installation Low maintenance costs compared to gutters or interior drains Can be adjusted to fit any size of flat roof Cons: Prone to clogging due to debris and leaves Overflow from rainstorms can cause damage to surrounding areas Can be difficult to install correctly if the roof does not have the right slope When it comes to selecting the best drainage system for your flat roof, there are a few things to consider. Gutters, interior drains, and scuppers all offer their own advantages and disadvantages. It is important to select the right drainage system for your needs in order to ensure the longevity of your roof and protect it from water damage.
