Roofing Alphabet: R is for R-Value

If you are looking into getting a new roof, roofing contractors in Overland Park may bring up the term “R-Value.” Unless you’ve done your research or have worked with a premier roofing company in Overland Park before, the R-value of a roof is probably a foreign term to you. So what is an R-value and why is it important?  


Proper residential and commercial roofing in Overland Park, KS is important in defending and protecting you from extreme weather, but is also what helps keep a building insulated. Adequate insulation will help decrease your energy bills and protect your building from damage. To determine the effectiveness and ability of roofing material to resist thermal movement, an R-value is calculated.   


The higher the R-value, the more insulated a roof is and effective its material. This means your roof will keep cool air in during the summer and cold air out during the winter, thus resulting in lower energy bills. To calculate the R-value of a roof system, roofing contractors in Overland Park will look at everything from the insulation, membranes, adhesives, underlayment, and more. The R-value depends on the material used, its thickness, and density.   


Codes and R-value requirements vary from state and even city. Roofing companies in Overland Park are knowledgeable on the different energy codes and minimum R-value’s that are determined by local jurisdiction. When replacing your roof, the best roofer in Overland Park will take into account your city’s building codes.
