Factors that impact the cost of a new roof

The size and pitch of your roof, the location of your home, and the roofing materials you select are important factors that will influence the cost of your roof replacement.

Understanding your roof replacement cost

A new roof is so much more than just shingles. Before you talk to a contractor about your roof replacement project, it’s helpful to know some of the elements that go into a typical roofing estimate.

How many pros calculate an estimate for a roof replacement

  • Roof square footage - Contractors get most roof measurements digitally, using satellite images or drones. The measurements include facets, pitch, eaves, rakes and more. Learn about the parts that make up a residential roof.
  • Condition of Roof - The contractor may get up on your roof to check the condition of the shingles and other parts of the roof to figure out the scope of the project.
  • Recommended roof materials - Your contractor will outline the materials you need for your roof replacement, including shingles, ventilation products, and underlayment. The cost of products varies depending on the materials you choose.
  • Warranty options - Eligible warranties may vary depending on the combination of products that are installed, as well as the certification of the contractor installing them. Contractors certified by GAF can offer our strongest warranties for your roof replacement. It’s always a good idea to learn about all of your warranty options. If you think your roof was damaged by a storm, or may be at risk of future storm damage, see our storm resources.
  • Calculate labor costs - To complete the estimate, your contractor will add in labor costs, and any fees that may apply for services such as permitting and disposal.

It pays to be an educated consumer for a home project like a roof replacement. Be sure that you understand all project costs before you accept an estimate. Click to learn more about how to plan for your new roof.

  • Choose a trusted contractor - A reliable contractor will readily answer any questions you have about your roof replacement and work with you to recommend the best roofing materials for your home and budget.
  • Look for a cost breakdown - Know exactly what you’ll get for the money you’re spending. Your contractor should be able to provide an itemized cost breakdown as part of your estimate and answer any questions you have.
  • Missing warranty information - Your contractor should be able to give you a full, clear explanation of available warranties and coverage, and that information should be reflected in your cost estimate.
  • Ask about clean up costs - The cost to remove old roofing material and clean the work area during and after installation should be part of your estimate, not a surprise cost that pops up later. A reliable contractor will be able to provide you with a solid number on your estimate.
  • Be wary if the estimate looks too good to be true - Because if it does, it probably is. Be sure your cost estimate isn’t missing any roofing materials or expenses. A low cost is not always the best choice.

Credit Cards

Using a credit card may be a good solution to short-term cash flow gaps, especially if you have access to low interest rates or rewards. Not all contractors accept credit cards — ask if yours does.
