How Much Does Roof Replacement Cost in St. Louis? [2025 Data]

St. Louis’s frequent thunderstorms, hailstorms, and tornadoes can take their toll on local roofs. Replacing a roof in St. Louis costs an average of $8,155, with most new roofs costing between $5,433 and $11,032. Explore some of the main factors that contribute to the cost of a new roof so you can budget correctly for this project.

Roof Replacement Cost Factors

When you start seeing signs you need a new roof, trying to figure out how much to budget for roof replacement can be a daunting task. The cost of a new roof is based on the roof size, what it’s made of, how complex it is, and more. Take a look at some of the things that affect how much you’ll pay for roof replacement in St. Louis.

Roof Size

The size of your roof is one of the major determining factors in how much it’ll cost to replace. Roof size doesn’t always directly correlate with your home’s square footage—the pitch of the roof, roofing over porches and garages, and the size of your roof’s overhang can all add to roof size.

Roofing Material

Roof replacement costs will vary based on what your roof is made of. Asphalt shingles are a popular, budget-friendly option at about $3 to $11 per square foot, while metal roofs, which hold up well to the area’s extreme weather, can cost $5 to $22 per square foot. If you want a premium roofing option, slate roofing costs an average of $10 to $30 per square foot.

Roof Complexity

A roof with multiple penetrations like chimneys or skylights, architectural features like gables or dormers, or areas with varying pitch will cost more to replace. Complex roofs require additional materials, precise installation on multiple surfaces, and a longer installation time. Expect to pay extra for a roof with a complex roofline when compared to a simpler design.

Roof Removal

You’ll need to remove old roofing materials before replacing your roof, and that can add to your total project cost. Roof removal and disposal costs an average of $1 to $5 per square foot, so confirm with your roofer if removal costs are included in the quote. 

Additional Services

If you’re getting other services like gutter installation, sheathing replacement, or skylight installation when you have your roof replaced, it’ll add to your final bill. It’s often a good idea to update roof-related materials when you replace your roof so your home’s roofing and roof drainage systems are in similar condition.

Warranties

Manufacturers and roofing installers may include limited warranties in the up-front roofing price. You may choose to purchase additional warranties that can cover minor repairs, regular inspections, and manufacturer defects for a longer period of time. Warranties can add $500 to $5,00 to your project cost, depending on the warranty details.

Roof Replacement Pro Costs

Roof replacement should be handled by a local roofing pro—DIY roof installation can lead to structural problems, water intrusion, issues with your homeowners insurance, and voided manufacturer’s warranties.

Roofer Costs

Labor costs will be about half of your total roof replacement costs, with materials making up the difference. Roofers in St. Louis will charge for labor in different ways, including per hour and by the square foot—either way, labor costs should be included in your roofing estimate. It’s not necessary to tip your roofer, but you may want to set aside a small amount for food and drinks for the hardworking team.

Permits and Fees

The city of St. Louis requires you to obtain a permit if you’re replacing your roof with a new roof of a different material, or if you need to replace more than 25% of the roof sheathing. Check with your contractor to see if you need a permit for your roof replacement so you can budget for any necessary fees. Permit and application fees start at $44 and increase based on the total project cost.

Does Roof Replacement Increase Home Value?

Replacing your roof can add value to your home, offering a return on investment (ROI) of 50% to 60%. How much your new roof affects your home’s value depends on the material, professional installation, expected lifespan, and more. A new roof is also an enticing feature for potential buyers when it’s time to sell your home. Look into roof financing options to replace your roof before selling to set your home apart from similar properties.
