Many homes with large and complex roofs find their roof size falls around 3,000 sq.ft. This is a popular size for many homes with cross-gables, hipped roofs, large dormers, and unique roof shapes. These roofs are often very attractive, designed to be one of the most eye-catching features. They can use a range of materials, making the cost of a new roof variable.

The national average cost to replace a 3,000 sq.ft. roof is $14,250 to $30,000, with most homeowners paying $21,000 for a mid-grade architectural shingle roof replacement on a cross-gable roof. This project’s low cost is $9,000 for a roof replacement using basic 3-tab shingles on a gable roof. The high cost is $90,000 for a roof replacement using clay tiles on a cross-gable roof with roof deck reinforcement.

Many factors impact a 3,000 sq.ft. roof cost. This includes the roof’s complexity. While you can have simple gable or hip roofs that are 3,000 sq.ft., many roofs of this size are more complex with cross-gables, clipped corners, valleys, or decorative elements. The more complex a roof, the higher the cost to replace it. For example, a complex mansard roof or dormer roof is more costly to replace than a basic gable roof. Very steep roofs, such as A-frames, can also be more costly to replace. The material you choose can also impact the project cost for the material and labor. Below are the average costs to replace a 3,000 sq.ft. roof based on levels of quality, difficulty, and installation.

3,000 sq.ft. roofs can use a range of materials, from low-cost asphalt to high-end copper and slate roofs. Most mid-range costs are associated with materials like architectural shingles, composite shingles, and metal roofs like aluminum. Higher-end materials like tiles may also have higher costs due to the potential need to reinforce the roof deck to hold them.

Additional Considerations and Costs

• Materials. You can use many materials to roof your home, and each has different material and labor costs. Some popular materials for roofs include asphalt shingles, cedar shakes, tiles, and metal.
• Lifespan. Your roof’s lifespan is impacted by the material. Some materials like asphalt may last 20 to 30 years, while others, such as slate or copper, can last up to 200 years with proper care. Ask your roofer what lifespan you can expect for your new roof.
• Maintenance. Your roof’s maintenance is also affected by the material. Some materials like copper are low maintenance, while others, such as tile, can be very high maintenance due to the need to replace the underlayment frequently. Speak to your installer about what maintenance your roof may need.
• Shape and pitch. Your roof’s shape and pitch impact total costs. The more complex your roof shape and the steeper the pitch, the harder it is to work on and the higher your costs.
• Guttering. It is common to replace the gutters on your home when you replace the roof. New gutters cost between $900 and $5,000, depending on the material.
• Permit. Depending on where you live and what work you have done, you may need a permit to replace your roof, particularly if you need to modify the roof deck. Speak to your local municipality for more information.
• Insurance. Your roof can impact the cost of your homeowners insurance. Speak to your insurance adjuster for more information.
• Inspection. If you are unsure whether your roof needs to be replaced, schedule an inspection. Inspections cost between $100 and $600 and help discover the state of your roof.
