4 Factors That Affect the Cost of a Replacement Roof

One of the most important components of your home’s structural integrity is its roof. Not only must it be strong enough to withstand a wide array of weather events, it must protect you and your family from the heat as well as the cold.

Over time, however, those environmental elements start to wear down your roof. Missing, curling, or buckling shingles are a sure sign that it may be time for a replacement. A weakened roof system leaves your home vulnerable to moisture, mold, and mildew damage, insect or rodent infestation, higher utility bills, and overall structural damage to its other components.

While some roof issues are easily noticeable, others are not. The first step should be to set up an inspection with a reputable company that offers roof installation in Dunwoody and the surrounding area. An inspection will reveal whether your roof needs a complete replacement, or whether an emergency roof repair will correct the issue.  

The roofing professional should provide a written estimate which should include a close approximation to the roof repair cost for both materials and labor. However, there are factors that can affect the final cost.


Steep roofs may not be walkable and require additional planning and setup, which increases the labor costs. The slope or pitch of the roof also determines what type of system is installed underneath the top, visible layer of roofing. Depending on what type of material is used to replace your roof, there are code differences the contractor must abide by according to its pitch. Flat roofs, for example, require different under-materials than pitched ones.


There is a vast selection of roofing materials available on the market, in a wide array of prices, not only for the visible outer layer of the roof but for the layers underneath the shingles as well. Higher quality, superior roofing products offer a longer service life and better protection for your home and its structural components, and will likely be reflected in the cost.  


There are two costs associated with old roof removal: the amount of time it takes to remove the old layer or layers, and the disposal of them. Some types of roof materials are heavier than others, and the heavier they are, the longer it takes. If there are multiple layers underneath, that adds to the cost. The more material removed, the more it costs to dispose of it, and those charges are passed on to the customer.

Roof Size

Roofing materials are generally sold by the square, not the square foot. A larger roof requires more squares, with one roofing square equaling 100 square feet, and will cost more to replace.

A new roof can completely change the appearance of your home or complement its architecture. For a reliable roofing estimate in Dunwoody, call Superior Roofing today.
