The Most Common Types of Flat Roofs, According to Roofing Companies in Iowa City Maybe you were not aware of the difference between a residential and a commercial roofing company in Iowa City. As all roofing companies in Iowa City know, flat roofs are a popular option in Iowa for commercial buildings. Many consider flat roofs to be one of the most cost-effective options for businesses while still providing the structure and quality needed to protect the structure.    

Flat roofs come in different styles, so it might be a bit of a challenge deciding on which option is best for your building. Widely regarded as one of the best roofing companies in Iowa City Robison will explain the different types of flat roofs so that you can make a more informed decision. Some of the most common flat roofs in Iowa are:  

  • Single-Ply Membrane 
  • Built-Up Roofing (BUR) 
  • Modified Bitumen 
  • Metal Roofs 


Roofing Companies in Iowa City Recommend Single-Ply Membrane   

The best roofer in Iowa City recommends single-ply roofing thanks to their longevity. The roofing material consists of flexible, prefabricated sheets made of synthetic materials that can withstand the harshest conditions. Single-ply systems are also energy-efficient, which can lead to additional savings on your utility bills.

Roofing Companies in Iowa City Recommend Built-Up Roofing 

One of the oldest but useful commercial roofing methods is Built-Up Roofing (BUR). The best roofer in Iowa City refers to this design as “hot-mop” or “tar and gravel” roofs. BUR involves layering asphalt with roofing felt to create a membrane designed to withstand the Iowa sun. It is then topped off with a roof coating for an extra layer of protection from the heat.

Roofing Companies in Iowa City Recommend Modified Bitumen 

Modified bitumen is like BUR as the process involves layering.  However, modified bitumen has additional materials such as polymers and fiberglass for extra durability. One layer can have a lifespan of up to 16 years, but the best roofer in Iowa City knows adding additional layers can extend the roof’s life several more years.
