Commercial Roofing Basics Property Owners Need To Know

Many think that commercial roofing is just the same as residential roofing, however, these two industries are not the same in many aspects. The installation of commercial roofing is different from the installation of residential roofing. The problems, applications, and solutions are also very different.

Systems Available

One of the most striking differences between residential and commercial roofing is the systems available. Residential roofing systems are usually concrete tile or asphalt shingle and it varies based on the climate. Property owners have more roofing system options in commercial settings. Typically, a commercial roofing minneapolis company includes restoration coatings, sprayed polyurethane foam, single-ply, concrete, tar and gravel, modified bitumen, and many others.


In addition to the systems available, another difference between commercial roofing and residential roofing is their installation. Commercial roofs can take more than a month to install while the majority of residential roofs can be installed in just a couple of days. The difference in the time frame between these two roofing systems is due to the size of the building or property. Commercial buildings are much larger compared to residential properties. Additionally, commercial roofs are more complex and far more difficult to install compared to residential roofs. The installation requires several days for curing, settling, gluing, and several other time-consuming tasks required in the installation process.

How Problems Are Solved

Residential roofs differ from commercial roofs in terms of how common roofing problems are solved. A leak in a residential roofing system will only require a patch where the leak comes from. In the commercial roofing system, you not only patch the portion where the leak comes from you also apply the coating to the entire roof. It is possible that the leak is an indication of a bigger problem that may require roof replacement or new flashings.
