A Brief Rundown of Roofing

What You Need to Know about Commercial and 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.

The first thing to mention is the size difference in constructing a commercial roof from that of a residential roof and thus the structural needs differ. As an example, take the size of the roof of your house compared to that of the roofing of a commercial building, which the load requirements, fixtures and materials will of course differ. 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.

As to the function of the roof, note that commercial roofs have more protrusions compared to a residential roofing. 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. One reason is the function of the building, as for instance, if a commercial roofing is for an establishment meant for heavy machinery, then its roofing must be able to withstand heat discharge. While a residential roof may be constructed based on the personal preferences of the homeowners as in its appearance, maintenance and durability.

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. While a commercial roofer has to take into account the function of the commercial building, the residential roofer on the other hand has to take into consideration the special needs of the homeowners.

The above mentioned general differences of the two roofing contractors scope of job will also find them needing different requirements as well. Of the two contractors, the commercial roofing contractor is viewed to be more difficult and more involved in the job because of the scope of the job, and in turn affecting the fact that it is difficult to find skilled workers and the number of this skilled people, which in turn would affect the cost they will give you of the project.
