What You Need to Know about Commercial and Residential Roofing
As you start to look for a roofing contractor, be aware that the first question the professional will ask you is if you are in need of a residential or a commercial roofing contractor, because even if the purpose of these two is the same, conducting each project will be different. Note that from design to the structural elements, their materials and costs, would differ in commercial to that of a residential roofing.
Obviously, the structural needs of a commercial roof is different from that of a residential roof because of the size involved itself. 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. In the same manner that you would need more number of crew when installing a commercial roof because it is a bigger job compared to a residential roof.
With regards to the function of the roof, compared to residential roofs, a commercial roofing has more protrusions in comparison. Note that not only will a commercial roofing accommodate ventilation system, smoke stacks, pipes, roof entrances and other mechanical needs, it could still need to entertain positioning of skylights, chimneys and others that residential roofing only has and can only accommodate. Depending on the needs, there could be some special construction specifications that could occur for a commercial and residential roofing. 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.
These differences of roofing projects would put also the two different roofers having different needs to complete the work. Generally, of the two roofing contractors, the commercial roofer is considered as a much more involved and more difficult job in terms of finding skilled workers and the number of people to do the job, and because of this, they will be charging you a different cost because of the scope of the job.
