Difference Between Residential Or Commercial Flat Roofs

Aug 16

One roof would seem to be the same as another. Commercial roofs are often quite different from residential ones. There are three main differences between residential and commercial roofs: design, material choice, and installation requirements.

Roof Design

The most noticeable difference between residential and commercial roofs is the design. Commercial roofs tend to have a shallow slope or flat surface. These roofs are often found in factories, shops, restaurants, and warehouses. This roof is typically more significant than a residential roof. The roof's surface can house heavy items such as large HVAC blowers or industrial pipes. Multiple openings can be made for smokestacks, blower outlets and skylights.

Residential roofs tend to be higher pitched than commercial roofs. In most cases, it is smaller than commercial roofing. Except for solar cells, there is almost nothing directly on the surface. The roof has very few openings. They are usually limited to skylights, vent stacks and chimneys.

Roof Materials

The materials used for commercial and residential roofs will vary depending on their design, cost, and weather conditions. A commercial roofer can help you determine the best materials to use for your roof. Asphalt shingles are the most preferred roofing material for residential properties. These shingles are very easy to install and cost-effective. Wood shakes, metal panels and slate are all standard options for residential properties. Tile, ceramic, and tile are also popular choices.

The most common method for constructing a residential roof is to attach plywood to wooden beams, creating the roof deck. After laying the plywood, the roofer will apply a protective underlayment before installing shingles or shakes.

Low-pitched or flat commercial roofs are not suitable for residential roofing materials. These roofs are commonly covered with modified bitumen, tar, gravel, single-ply covers (PVC TPO, EPDM), spray polyurethane foam, or other commercial roofing materials.

A commercial roof requires multiple layers. These include insulation, decking and a protective coating. The type of roofing used will determine the exact number of layers.


Commercial roofing materials are more diverse than residential. Property managers and owners must find a commercial roofer who is qualified and experienced in repairs and installation.

Roof Repair and Installation

Residential and commercial properties have different requirements for installation and repairs. A commercial roof, for example, can take up to a month to install due to its sheer size and the many layers. Because it is simpler to construct, a residential roof can be installed in a few days.

Commercial roof repairs can be a huge undertaking. The entire roof should be evaluated if water penetrates the layers. The roof repair may be limited to one area of the roof. Or it could involve major repairs and reapplying layers over a large portion of the roof. Simple leaks can cost a lot.

Leakages can occur when flashing or shingles become loose on a residential roof. Most of the work can be completed in just a few hours. A residential roof can leak, which can indicate serious problems. But, this is usually less common than isolated leaks caused by minor problems.

Commercial and residential roofers have different skills. Commercial roofers must recognize the many options available and how to fix them. A residential roofer requires a lower level of skill. These roofers work primarily with asphalt shingle roofs, which require less skill than a commercial roof.

The fourth distinction between residential and commercial roofing is how they are maintained. The homeowner usually only needs to inspect a residential roof once a year. The homeowner inspects the roof from ground level and looks for damage caused by storms or other circumstances. Missing shingles and detached gutters are indicators of damage.

A professional roofer is responsible for inspecting and maintaining commercial roofing. The contractor must inspect leaks and other signs of damage. Professional inspections are more common for flat roofs on commercial buildings. An inspector should be called upon regularly. After mechanical equipment contractors have been working there, the inspector must inspect the roof surface to ensure no damage.


A roof can enhance a home's curb appeal and not only protect it from the elements. A roof is an essential part of residential design. A roof can make a house more attractive to buyers by being visible from the outside and to passersby.

Flat design is a characteristic of commercial building roofs. They are often not visible to passersby. The slope is usually not more than the minimum required to allow water drainage and prevent water pooling. Flat roofs are often referred to as low-slope roofing because of their slight but not noticeable slope.

Commercial and residential roofs serve different purposes. Commercial roofing is often designed to serve a specific purpose, rather than using patterns, colors, or decorative designs like residential roofs. Commercial roofs can also be extended over more extensive areas using rooftop measurements. This is because they apply a lot of pressure to the structure. Residential roofs are smaller and don't create as much structural pressure.
