Replacing a roof can be a significant expense for any homeowner. The cost of the project can vary depending on several factors, including the size of the roof, the number of penetrations, such as chimneys and skylights, and the level of difficulty involved in the installation. The type of materials used for the project can also affect the cost.

According to the U.S. Census Bureau, the average single-family home in the US has a roof area of around 1,700 to 2,100 square feet. The average cost to remove an existing asphalt roof and install a new one is estimated to be between $5.00 and $6.00 per square foot. Based on these estimates, the average cost to replace an asphalt roof for an average-sized single-family home would be around $10,450.

However, the cost can vary based on the type of home. For instance, a standard cape may cost around $6,000 to replace its roof, while a typical colonial with a 2-car attached garage may cost around $12,000.

The cost range is determined by the brand and type of materials used, the skill level of the labor, and the profit and overhead of the company performing the installation. It’s important to note that there may be outliers outside of this range. The less expensive options may not be qualified, not use appropriate materials, be unlicensed, uninsured, not pull permits, or a combination of these factors. On the other hand, more expensive contractors may have higher overhead, act more like a sales company than a contractor, and try to sell exclusive or proprietary products, and extended warranties.

In conclusion, when getting quotes for your roof replacement project, you may receive a wide range of pricing. It’s important to consider the factors that influence the cost and to choose a reputable contractor who uses quality materials and has appropriate licensing and insurance. By doing so, you can ensure a successful roof replacement project that will protect your home for years to come.
