How much does it cost to replace a 2,500 sq.ft. roof?

​No matter your home’s style or location, your roof plays an important role in how well your home looks and functions. Roofs help keep the elements out of your home and regulate your energy efficiency. They also enhance your home’s appearance and influence its curb appeal. If you have a larger roof at 2,500 sq.ft., you likely have a more complex roof with several gables, dormers, or a larger hipped, gambrel, or mansard roof. These roofs require a lot of material and labor to replace and have varying costs, depending on your roof’s material, shape, and size.

The national average cost to replace a 2,500 sq.ft. roof is $11,875 to $25,000, with most homeowners paying $17,500 for a roof replacement using good-quality architectural shingles on a cross-gable roof. This project’s low cost is $7,500 for a replacement using 3-tab shingles installed on a gable roof. The high cost is $75,000 for a replacement using clay tiles with roof deck modifications and reinforcement on a cross-gable roof.

Many things impact the cost of replacing a 2,500 sq.ft. roof. Roofs of this size are often more complex, with several peaks, angles, or sides than smaller roofs. For example, a roof of this size may be hipped with 4 sides, or it may be a cross-gable roof with 3 or 4 sections. The more complex the roof, the higher the costs. Roofs with steeper pitches, such as A-frame and mansard, may have higher costs. If your roof is in poor condition or requires roof deck replacement or reinforcement, this also impacts costs. Below are the average costs to replace a 2,500 sq.ft. roof based on the different levels of quality, difficulty, and installation.

In addition to your roof’s complexity and shape, the materials also impact costs. You can use many materials to cover your roof. Low-cost materials include basic asphalt shingles and 3-tab and basic laminated shingles. Mid-grade materials may include better architectural shingles and metal roofs, such as aluminum. You can also use more costly materials like copper, clay tile, and slate shingles. These materials may require more labor to install and roof deck modification, increasing costs.​

Additional Considerations and Costs

• Materials. You can use many materials on your roof. These include basic asphalt shingles, composites, cedar, and many types of metal. Each has costs and impacts on longevity and durability.
• Lifespan. Your roof’s lifespan is linked to the material. Some materials like asphalt last 20 to 30 years, while materials like copper or slate can last up to 200.
• Maintenance. The maintenance is also impacted by the material. Some metal roofs are very low maintenance, while tile roofs are higher maintenance due to their need for underlayment replacement. Speak to your installer about what the maintenance is for your new roof.
• Shape and pitch. Your roof’s shape and pitch impact the total cost. The more complex the roof and steeper the pitch, the higher the labor costs.
• Guttering. It is very common to replace the gutters on your home when you replace the roof. The average cost to install new gutters is $900 to $5,000, depending on the material.
• Permit. Some states require a permit for installing a new roof or making modifications to the deck. Check with your municipality to find out which permits you may need.
• Insurance. The material may impact your insurance costs. Speak to your insurance adjuster for more information.
• Inspection. If you are uncertain if your roof needs a replacement, an inspection may help. During an inspection, the roofer can look for signs indicating that your roof may need repair or replacement. The average cost is $100 to $600.
