Commercial and residential roofing differ in its specifications and materials. But with these differences, both also have the same purpose and that is to protect the property from the weather or climate elements. There are many materials and style to choose form for residential roofing. These choices are basically dependent on the design aesthetics and the preferences of the homeowners. However, both commercial and residential roofing have to put into consideration the damage and risk of the construction and the potential repair costs involved in the future. Basically these differences between commercial and residential roof, and these lie in consideration of the materials and design.


Let us talk about what are common to commercial and residential roofs. Each type may have a roof made of asphalt or slate, tile, ceramic or wood shakes. Both could have the modern solar or built-up roofs. The differences of the two types could be in the angle or slope of the roof. Commercial roofs usually have flat roofs while residential roofs are more inclined or steep.


Another difference is that the size of the commercial roof is much bigger than residential, and so the scope of the project requires more skilled workers and time of the project. It is seldom to find roofers performing both types of roof. The commercial roofing repairs companies employ more skilled and experienced workers.


The design of the building plays a great part in the cost of the project. Commercial roofs are generally flat while residential roofs are usually steeper. The size of the building also is another difference. With the size, comes consideration on the installation factors. Flat roofs usually needs regular repairs and proper maintenance since this type is more susceptible to leaks. Plus commercial roofs have to be able to hold more weight, and this means more costs.


It is a fact that residential roofs are easy to install, and repair and maintenance are also not as tedious as the commercial ones. The roofers have smaller features to consider like chimneys or few vents. While commercial roofs, have several considerations of the features of the building like smoke stacks, air flow systems, and external pipes found only in commercial buildings.


Material in commercial roof is distinct and is still the same over the years in its procedure. The material is coated with hot tar substance and is generally water proof and strong. As technology improves, commercial roof has improved in its substance to increase protection in insulation and improve energy efficiency. There is also a procedure of spraying this new material or coatings and this can considerably save old materials and eliminate replacement of the roof.



Most homeowners know little about their roof and so they leave the repairs and maintenance to the home roofing contractors professionals. The shape of the roof is a challenge and concern in residential roofs. Because of the slope, damages are not easily detected and only when the damage is great that the problem is noticed.
