Know These Basic Differences Between Commercial and a Residential Roofing
There are key differences between a residential and a commercial roofing even if they serve the same purpose, and so take note that the first question a roofing contractor will ask you is if you are in need of a residential or a commercial roofing job. Note that from design to the structural elements, their materials and costs, would differ in commercial to that of a residential roofing.

Imagine for example the size of the roof of your house compared to the size of the roof of department store, where the load requirements, fixtures and materials will definitely vary. Because of the materials necessary in the construction, a commercial roof has to have a larger load-bearing capacity than that of a residential roofing. Since the size of a commercial roofing is bigger than residential roofs, you would need a much larger crew to mobilize your job.
Compared to a residential roofing, commercial roofs have the tendency to have more protrusions with regards to the function of the roof. A commercial roofing will have to consider several protrusions like ventilation system, smoke stacks, pipes, roof entrances and other mechanical needs, aside from the usual skylights, or chimneys that a residential roofing usually only has. Both commercial and residential roofing could have some specialized construction specifications depending on the needs. It could be a reason of the function of the building, like if a building is for a heavy machinery establishment, then the roofing must be able to withstand the discharge of heat. In residential roofing, the construction on the other hand would depend on the personal preferences of its homeowners, from the choice of appearance, durability and maintenance.
With the size and scope of the project for either commercial or residential, you have to consider too the specialized knowledge and skills of your potential roofers. There are matters to be taken into account for both roofers, like the function of a commercial building for a commercial roofer, and the special needs of a homeowner for a residential roofer.
