3 Things To Consider When It Comes To Commercial Roofing

Posted on: 31 December 2017

Replacing the roof on a commercial building tends to be different than replacing the roof on a private residence. Commercial buildings, whether it's an office building or a warehouse facility, tend to be much larger than most residences. The materials used often differ from what is commonly used for roofs in private residences as well. The construction process also tends to be different since the roof is so much larger. When replacing the roof on a commercial building, here are three things to keep in mind.

Choose Roofing Contractors Carefully

When replacing the roof on a commercial building, choosing the right commercial roofers is key. A new roof on a commercial building is a big project. Choosing a contractor that is not experienced or able to handle the scope of the project can spell disaster down the line. It's important to look for roofers with both experience and good reputations. Comparison shopping is also important. Extremely low bids should be looked at with suspicion since it can indicate a lack of experience. Another thing to ask for is the roofing contractor's Experience Modifier Rate, or EMR. An EMR above 1.0 indicates that the company is safer than average and also tends to perform better than other companies.

Roof Type

In general, most commercial buildings have flat roofs. Flat roofs do have a slight slope to allow for draining of rain and snow. These types of roofs are more cost-efficient than pitched roofs for large buildings. When it comes to flat roofs, there are plenty of options to choose from. Some common materials include metal, asphalt rolls, sprayed polyurethane foam, and built up roof which uses materials such as tar, fiberglass, and roofing felt. Another thing to consider is energy efficiency. Roofs with cool roof coatings or light-color surfaces can save money on energy bills.


Another thing to consider is the cost of the new roof. Commercial roofing costs on average between $1.50 and $10 per square foot. Simply having a new roof installed is also not the only cost to consider. A roof that is not properly maintained can have years shaved off its lifespan. Maintenance costs should also be considered. On average roof maintenance will cost about 2 percent of the total cost of the roof per year. 

Replacing the roof on a commercial building is a major project. When it comes to commercial roofing, there are a few things that need to be considered. Choosing a roofer that has a solid safety record and a good reputation is very important. There are also a variety of roofing types to choose from. The overall cost is also something that needs to be considered. Not only does the cost to build the roof need to be budgeted for, but the cost of maintenance must also be factored in.
