How Much Does a New Roof Cost?

How much does a new roof cost? The question is asked with many variations. For instance, one home owner may phrase it as how much does a new roof cost per square (a square is the typical unit used for home construction, and measures 10 x 10 feet, or 100 square feet). Another may ask how much does a new roof cost in 2012.

Let’s try and address each of these questions and variations in a way that makes sense to home owners like you. First, let’s address what goes into replacing a roof or installing a new roof.

The existing roof on old buildings needs to be fixed or torn off. At the time, if any problems are identified in the substrate, they can be fixed and replaced. With the framework solid, you then start laying the new roof in a systematic manner and following good practices. Be sure that ventilation, water proofing and ice shields are included, and valleys properly done to prevent leaks. While the cost may be a little higher, it is well worth doing this well in the long term.

While picking roofing materials, be sure to choose good quality ones like brand manufacturers including GAF and Timberline. Local hardware stores may be able to guide you towards the best options. Select a roofing contractor carefully and get references to make sure they can do a good job. Ask for at least 3 quotes from different contractors and pick the best suited for your job.

How much does a new roof cost on average?

Considering that the typical home measures around 20 to 30 squares, the material and labor together will cost around $10,000 for a new roof. But this is only a ballpark figure and there are many variables that will affect this cost.

Tearing down the older roof and disposing off the waste is one of the major components of how much does a new roof cost. Another is the quality and amount of the materials. Higher quality material is more expensive, but will last for much longer. Larger buildings and bigger roofs will take more quantity of materials and add to the cost of a new roof.

Some contractors will suggest laying a new roof over the existing one itself, to save on what a new roof will cost. But that is not always a good idea, because of zoning restrictions, the greater weight of the reinstalled roof and the likelihood of problems with the old roof which can need correction later on.

Air circulation between the layers of your replaced roof is also a problem, which can lead to heating up of the roof and shingles, resulting in earlier damage. Costs of heating and cooling the building may also go up. All of this adds up to an expense that may end up greater than the $200 per square average which is how much a new roof costs.

Geographic location and easy availability of skilled labor are other factors that impact the cost of a new roof. The degree of difficulty involved in laying your new roof will also influence how much does a new roof cost.
