A roofer is a worker with the professional knowledge in the construction of a roof. Roofers ensure that the process of roofing is done appropriately both in the commercial and residential construction through extensive monitoring and evaluation. Commercial roofing jobs involve projects which are larger in size compared to the residential roofing jobs. In commercial roofing, there may be higher compliance and reporting steps involved than in residential roofing.

Roofers make an analysis of the construction plans, following a step by step plan with strict supervision, to ensure that the construction meets the original design of the project. Apart from the analysis, roofers equally establish the substrates, materials and supportive accessories to be used in the installation process. Roofers decide which specifications of the trusses, rafters, and beams on which the roofs are to be installed. This ensures that all the needed materials for the roofing are available before the process kicks off.

Roles of roofers include working on new installations, making repairs, roof cleaning and renovating roofs which are both new and those that already exist. At times, roofers go to the extent of replacing old materials with new, solid structures. Roofers deal with a wide range of variety of materials such as polymer, rubber, metal, tile and asbestos, with the materials having a widespread application in the domestic sectors as well as in industries.

Most builders prefer rubber roofs when dealing with commercial buildings. Due to the complexity of rubber roof installation, the process has to be managed only with the assistance of experienced roofers. Some rubber roof renovations force roofers to take up the responsibility of mopping the whole flat area of the roof in a uniform way using a warm melted tar coat. The installation process of the rubber sheet involves measuring and cutting of protrusions such as skylights, vent pipes, and heating units.

There are considerations taken in place by roofers before roofing; the roofers have to inspect whether the existing roof needs repair or making an identity of the project if it involves a new building. Roofers are usually forced to remove the existing materials before they lay down a layer of fresh tar paper and installing of new materials by either using staples or nails. Roofers have to do this when dealing with jobs that involve shingle, metal and tile roofing.

The most common jobs performed by roofers include tile removal, tar application, shingle installation, rubber roof installing and job estimating. Of all the jobs done by roofers, the most important one is job estimating. The role of the roofing job estimator is to make estimates at the expense anticipated in the installation of a new roof.

When making the estimate, the roofer has to have the ability to formulate accurately and realistically estimates, which is very significant for both parties. The company provides a written estimate stating exactly the services to be provided with what expenses.

The company states the timeline needed for the construction together with the number of constructors that will carry out the job. If the estimate is too high, a there roofing company may lose the contract to its competitors’ who make low bids.likewise, if the company quotes too low, there is a high chance the company will not make profits.Therefore, the role of the estimator is critical for roofing companies.
