You might be astonished if you knew how much your roof really cost. The cost of a roof does not end with the installation - that is only the beginning. There is an analysis tool available that can help you compare the costs of owning a particular type of roof. The analysis tool is called Life Cycle Costing - it is essentially a calculator that uses the initial installation, lifetime maintenance, tear-off and reroof costs to calculate the lifetime cost of ownership.
Enter quotes in cost per square. To determine your cost per roofing square divide the total quote amount by your roof size in roofing squares (1 roofing square = 100 sq./ft.). If you don't have this information, contact your roofing contractor.
