Roof Installation Cost Basics

Price Range: $2 – $8 per square foot for installation

Generally, the removal or tear off of existing roofing will account for $2 per square foot of the install price. Nearly a third of the install price is the worker’s compensation insurance. The rest is the labor cost and profit for the company itself. Complicated layout patterns will add 10% to the price and any structural work should as reinforcing the roofing frame will add to the cost as well. It is important for the existing sheathing to be in decent shape (no delamination issues or in poor condition). If sections are in a state of disrepair, they must be replaced or repaired prior to the new roofing install to insure that no moisture or water is able to get underneath and cause serious problems.
