Roof Tear-Offs Impact the Roof Replacement Price

The first question everyone asks about replacing their roof is “How much does roof replacement cost?” The answer depends largely on whether or not a tear-off of the old roof is required.

In Wisconsin, the building code specifies no more than two layers of roofing material are allowed. If you have two layers of roofing already, we cannot put down a third. We will have to remove one layer of roofing material. If the outermost layer cannot be removed without compromising the first layer, or if the original layer is also in poor shape, a complete tear-off is in order.
