Cost of EPDM Flat Roof
The rubber roofing cost, particularly for epdm roofing cost per square foot, varies from one range to another range because of the availability of raw materials and skilled laborers.
On a typical flat roof, the install cost of an EPDM flat roof is expected to vary from $6.50 to $12.50 per square foot. Or for the low slope roof replacement, it varies from $9750 to $18750 for 1500 square feet.
The flat roof cost also depends on the number of penetrations, the number of layers of insulation, also the existing roof removing cost, and the cost depending on tear-off may be lower or higher.
And Other costs affecting factors are accessibility, overall roof difficulty, and the location of the project. For this above reason, we can say this flat roof system also increases the total cost of the project.
How to Install EPDM Rubber Roofing?
