Factors that impact the cost of a new roof
Home size
The size of your roof is the biggest cost factor. Divide the number of square feet of roof surface area by 100 to get the roofing square number. Cost per square usually includes materials and installation.
Roof materials
This is the most variable cost. Asphalt shingles are the most popular and typically cost the least. Metal, wood, slate, clay or solar roofing materials usually cost more.
Slope and pitch
Steep roofs can be more labor intensive, which may increase the estimate. The pitch and complexity of the roof may influence the roofing materials selected, which will also impact cost.
Where you live
The area you live in - its cost of living, climate, local building codes and permit requirements - are variables that also factor into the cost of your new roof.
Understanding your roof replacement cost
How many pros calculate an estimate
- Contractors get most roof measurements for square footage 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.
- 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.
- Your contractor will outline the materials need for your roof replacement, including shingles, ventilation products and underlayment. The cost of products varies depending on the materials you choose.
- Warranty options may vary depending on the combination of products that are installed, as well as the certification of the contractor installing them. GAF-certified contractors can offer our strongest warranties.
- To complete the estimate, your contractor will add in labor costs, and any fees that may apply for services such as permitting and disposal.

More tips to avoid hidden roof replacement costs
- Your contractor should be able to provide an itemized cost breakdown as part of your estimate.
- 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.
- 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.

Insurance
If your roof issue was caused by an unexpected event, such as a storm or a tree falling on your house, your homeowner’s insurance can be a great resource. If the issue is age or wear and tear, you will probably need to explore other payment options.

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.
