The Processes of Your Commercial Roof Installation in Illinois

by | Apr 17, 2018 | Roofing

Commercial roofing systems vary, as do commercial roofing contractors. The process isn’t as straightforward as residential roofing installation with asphalt shingles. There are different installation methods depending on what type of roofing system you decide on. Choosing your commercial roof installation in Illinois doesn’t have to be filled with guesswork. Knowing the basic processes of some of the more popular roofing systems will not only help you choose the right roof for your business but help you in selecting the right contractor to do the job.


If you want to give your business a new look, sprayed polyurethane foam for your roof might be what you need. It’s one of the more simpler choices for your commercial roof installation in Illinois. The process is usually in 3 steps–cleaning the roof, spraying foam on the roof surface, and lastly, applying a protectant on top of the foam. This last step is important because the polyurethane foam needs to be protected from the elements.


Another route you might want to go for your commercial roof installation in Illinois is single-ply. It’s a pretty uncomplicated process. However it can be more time-consuming. After a contractor rolls out the material, it will then be attached to the roof with glues, tapes, or other methods depending on the roofing material. The material can be made of various elements. Some of the more popular choices are Thermoplastic Olefin, (TPO), Polyvinyl Chloride, (PVC), and Ethylene Propylene Diene Monomer, (EPDM).

Built-Up Roof

This is a very common type of process because it is relatively inexpensive. It is a roofing system that has many layers, is a great insulator, and the top coat is typically gravel. However, there is a downside if you decide to go this route as your commercial roof installation in Illinois. The many layers can cause the roof to be very heavy, and may require joists to be placed in any existing roof to compensate for the weight–and this of course can increase the price.
