If you’re starting to think about replacing your roof, one of the first questions on your mind is likely: how much does a new roof cost? It’s a smart question—and one that deserves a clear, up-to-date answer. A new roof isn’t just another home improvement project. It’s a major investment in the safety, energy efficiency, and long-term value of your home.
In 2025, roof replacement costs have been impacted by rising material costs, ongoing labor shortages, and evolving local building codes. Whether you’re in Sacramento, Roseville, Redding, or any part of Northern California, understanding what goes into the actual cost of a new roof replacement can help you plan ahead, protect your home, and avoid budget surprises.
Let’s break down the key factors that influence the average cost of a roof replacement, what to expect from roofing contractors, and how Cobex Construction Group helps California homeowners get durable, high-quality roofs that are built to last.
Roof Replacement Costs: What You Should Expect
Average Roof Replacement Cost in 2025
The average roof replacement cost in the U.S. ranges from $5,400 to $19,800, with the average price coming in around $11,000. In Northern California, most homeowners can expect to pay between $9,000 and $18,000, depending on their roof size, choice of roofing material, and the architectural complexity of their home.
While these national averages are helpful, every home—and every roof—is different. Your total replacement cost depends on a variety of elements that affect both material costs and labor costs.
What Affects the Cost to Replace a Roof?
Your final project cost will vary based on several key considerations:
- Roof size and square footage: Roofing is priced by the “square”—equivalent to 100 square feet. A larger roof naturally costs more due to increased materials and labor.
- Roofing material: Your choice of shingle material, metal, tile, or premium options like slate tiles significantly affects the final price tag.
- Labor costs: In California, most roofing companies charge about $60 per hour or more. Labor costs typically make up 60%+ of the total project.
- Complex roof designs: If your roof has steep slopes, dormers, skylights, or multiple levels, expect higher installation costs.
- Old roofing material removal: Tearing off the existing system adds time and cost—typically $1,000–$3,000 for disposal and prep.
- Permits and local codes: In wildfire-prone areas of California, strict local building codes may require additional materials or design adjustments.
- Existing materials and condition: If your current roof has reusable components like decking or flashing, you may save slightly—although reusing components isn’t always advisable.
Because each home is unique, Cobex always offers personalized, no-obligation estimates to ensure you receive a clear, honest understanding of your roof’s condition and the cost to replace it.
Roofing Material Breakdown: Choosing the Right Option
Asphalt Shingles: Reliable and Affordable
An asphalt shingle roof is one of the most widely installed roofing systems across Northern California—and for good reason. Asphalt shingles are durable, cost-effective, and come in a wide variety of colors and styles. They typically last 20–25 years and are ideal for many one- and two-story homes.
In 2025, the cost per square foot for an asphalt shingle roof ranges from $3.40 to $8.75, depending on the quality of the product and the complexity of the installation.
Tile Roofs: Classic Style with Long-Term Durability
Tile roofs, including both clay and concrete varieties, offer excellent fire resistance and longevity. These roofs can last 40–50 years with minimal maintenance and are well-suited to California’s Mediterranean climate.
You’ll pay more for this style—anywhere from $11 to $25 per square foot—but the return comes in the form of energy efficiency, long-term durability, and aesthetic appeal. If you’re considering replacing your current shingle roof with tile, consult with your contractor about structural weight capacity.
Metal Roofing: Modern, Efficient, and Long-Lasting
Installing a new metal roof—such as corrugated metal or standing seam—offers significant long-term benefits. These systems reflect heat, resist fire, and require very little maintenance. They can last 40–70 years, making them a great investment for homeowners planning to stay in their homes long-term.
In 2025, metal roofs cost between $6 and $35 per square foot, depending on material quality, underlayment, and design.
Slate Roof: Premium Appeal, Premium Pricing
A slate roof delivers an unmatched level of beauty and lifespan, often lasting over 100 years. However, this luxury comes at a premium. Installing a full roof replacement with slate tiles can cost anywhere from $19,000 to $52,000+ and may require structural reinforcement due to its weight.
Slate is ideal for luxury homes or homeowners seeking a historic or architectural aesthetic—but it should only be installed by experienced roofing contractors.
Other Expensive Roofing Materials
Other high-end materials include copper roofing and cedar shingles. Both are known for their durability and unique look. While more costly than asphalt, they provide excellent longevity and standout curb appeal.
Labor Costs and What Roofing Companies Charge
What Most Roofing Contractors Charge in 2025
As mentioned, labor costs typically represent over half of your total roof replacement price. In California, roofing companies charge about $60–$80 per hour, depending on the crew size, project complexity, and time of year.
Steeper roofs or homes with multiple layers of existing materials take longer to complete, which raises your installation costs. Trusting a professional roofing crew ensures safe installation, code compliance, and full warranty eligibility.
Understanding Roof Size and Scope of Work
Pricing Per Square Foot
Most roofing contractors price work per square foot, often simplified into 100-square-foot units. These “squares” help standardize cost estimates and material calculations.
Average cost per square foot by material:
- Asphalt shingles: $3.40–$8.75
- Tile roofs: $11–$25
- Metal roofing: $6–$35
- Slate roof: $15–$40+
These costs include both material costs and labor costs, but upgrades such as underlayments, ridge caps, roof flashing, and existing gutter work may increase your final quote.
Average Roof Size in California
Most single-family homes in California range between 1,500 and 2,500 square feet. If your home has a larger roof, expect your replacement cost to increase accordingly—not just because of materials, but due to longer installation time and potential structural upgrades.
Roof Repairs vs. Full Roof Replacement
When Minor Repairs Are Enough
If your roof is relatively new and the problem is limited—such as missing shingles, minor leaks, or isolated flashing damage—minor repairs may be sufficient. A Cobex expert can assess whether a full replacement is necessary or if a focused repair will keep your roof performing well.
When You’ll Need the Entire Roof Replaced
A roof that’s over 20 years old, showing widespread cracking, sagging, mold growth, or persistent leaks likely needs a full roof replacement. Ignoring these signs often leads to escalating repair costs or internal home damage. Replacing the entire roof at once is usually more cost-effective than patching over ongoing problems.
What Else Impacts Roof Replacement Costs?
Hidden Damage and Structural Issues
During removal of your old roofing material, crews may discover underlying issues like rotted roof decking, pest nests, or moisture damage. These repairs must be completed before the new roof goes on and can add $500 to $5,000+ to your total cost, depending on the severity.
Energy-Efficient and Code-Compliant Upgrades
California’s evolving local building codes may require upgrades like enhanced attic ventilation, fire-rated materials, or reflective coatings. While these upgrades increase initial costs, they improve safety, reduce utility bills, and may qualify you for rebates.
Warranty and Premium Product Options
Choosing high-performance underlayment, upgraded shingle material, or an extended manufacturer’s warranty adds to the final quote—but also extends your roof’s life, improves performance, and enhances resale value.
Financing, Insurance, and Long-Term Value
Will My Insurance Company Help Cover Costs?
If your roof was damaged by a covered peril—such as hail, wind, or falling debris—your insurance company may cover all or part of the replacement. However, roofs nearing the end of their service life or suffering from wear and tear are generally not eligible.
Cobex works with you and your adjuster to streamline the inspection and claims process.
Financing Options for Roof Replacement
We understand that a roof replacement can feel overwhelming financially. That’s why Cobex offers flexible financing options, including low-interest and no-interest plans. Our team will help you choose a payment plan that works for your budget—without sacrificing quality.
The Long-Term ROI of a New Roof
A new roof boosts curb appeal, improves energy efficiency, increases resale value, and offers protection against future damage. On average, homeowners recoup 60–70% of their investment in added property value alone—making it one of the smartest upgrades you can make.
