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. Be aware that the differences between a commercial and a residential roofing project are very much different, from the design, structural elements, to the materials and costs.
Obviously, the structural needs of a commercial roof is different from that of a residential roof because of the size involved itself. 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. The fact that the materials involved in each construction differ, imagine that the commercial roofs have a larger load bearing capacity compared to that of a residential roofing. Consequently, a much larger crew is needed for the installation of a commercial roof because of the size of the job against 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. The function of the building to have the commercial roofing is a reason, which for example if the premise if for a heavy machinery production, the discharge of heat must be coped well with the commercial roofing Houston specifications. While a residential roof may be constructed based on the personal preferences of the homeowners as in its appearance, maintenance and durability.
The specialized knowledge and skills of the roofers in prospect have to be considered too considering the scope of the project for both commercial and residential. 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.
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 Houston roofing inspection 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.
