Commercial and Residential Roofing – What is the Difference Between the Two?

[ad_1]

Before a roofing job contract is made, one of the most basic questions a builder would probably ask you is whether the contract offer is for commercial roofing or residential roofing. But have you really wondered what exactly differentiates one from the other? To know the answer read ahead…

One of the most important points of difference between commercial and residential roofing is that though they are ultimately meant to serve the same purpose at the end of the day, they are still meant to serve on different kinds of roofs. In other words the design structures of the roofs they are expected to be constructed upon vary greatly.

Take for example window sidings. Can you imagine two differently designed windows having exactly the same sidings? Same is the case of roofing styles. Now we all are well aware of the difference in architectural designs of a typical housing building and a commercial building. For many it may be surprising to know that there is more to the difference in the design pattern of the roofs of such buildings than what meets the eyes. The two different roofing categories are meant to facilitate the specific requirements of these building designs.

Apart from the roof structure design, the size of the roofing also plays a very important role. In most of the cases it is seen that while residential roofing requires only a single or two workers on the job, commercial roofing requires an entire crew to be working together.

Another very important difference between commercial and residential roofing is that residential buildings usually tend to have less number of protrusions as compared to the commercial buildings. For instance, while most residential houses would be expected to have one protrusion for a single chimney, commercial buildings have to consider projections and lips for everything, starting from ventilation systems, smoke stacks, pipes, roof entrances, mechanical wirings, skylights, etc.

Besides, often the constructing agent might need to take into account serious specifications while selecting the roofing materials for commercial buildings (such as heat discharge from heavy machinery, chemical nature of the substances in use, etc), whereas, in case of residential houses, the only important specifications are personal choices about appearance, durability and maintenance.

Often because of these above stated factors, the small roof builders tend to consider commercial roofing as a more difficult job. Since it is not rare for commercial roofing contracts to come with large number of specifications, small builders might even hesitate to take up the job, unsure of whether they can promise enough manpower and handle the tools required for the purpose.

Other factors like unions to which the commercial builder and the commercial buildings belong can also play a significant role while commercial roofing. Needless to say, these complications are easily averted while roofing for a residential complex.

While these were the most basic differences between commercial and residential roofing, there are various other factors too that matter a lot not only to the builder but also the service receiver. Therefore, next time a constructor enquires whether you need commercial or residential roofing remember that this casual sounding question is actually what determines the very foundation of the entire job.
