The national average for replacing a roof on a 1,100-square-foot house is between $6,091 and $20,174, though this depends on factors like the floors in your home, your location, and your roofing material. Most homeowners spend about $7,925 on a roof replacement if their home is around 1,100 square feet.
A 1,100-square-foot home typically has a roof that’s larger than 1,100 square feet due to the pitch of the roof and the eaves that extend beyond the home’s foundation. For a 1,100-square-foot home, you’re looking at approximately 1,398 square feet of roof area for a one-story home or 733 square feet for a two-story home. Since roofers price their work by “squares” (100 square feet of roof), not by your home’s floor plan square footage, knowing this can help you better calculate the cost of your roof replacement.

Roof Replacement Costs by Story
The number of floors in your home impacts the cost of your roof. The more stories you have in your home, the smaller the size of your roof. Single-story homes spread living space horizontally, creating larger roof footprints that require more materials and labor hours than similarly sized two-story homes. The practical impact of this difference becomes clear when looking at roofing square footage—a 1,100-square-foot one-story home might need nearly twice the roofing material as a two-story home with identical living space. Accessibility factors also influence pricing, as single-story roofs typically allow easier access and simpler installation logistics, potentially offsetting some of the additional material costs through reduced labor complexity and equipment needs.
That said, when looking at the number of homes in the United States that have two stories, it’s just 5%. This means you’ll likely be getting a roof replacement for a one-story, 1,100-square-foot home, but we’ll share the estimated costs for both one-story and two-story homes of this size below.
| Stories | Est. Roof Square Footage | Average Cost | Cost Range |
|---|---|---|---|
| 1 | 1,398 | $8,118 | $6,240–$20,665 |
| 2 | 733 | $4,256 | $3,272–$10,835 |
Roof Replacement Costs by Material
Choosing the right roofing material for your 1,100-square-foot home involves weighing initial costs against long-term durability, maintenance requirements, and aesthetic considerations.
Asphalt shingles continue to dominate the residential roofing market due to their affordability and reasonable 15–30 year lifespan, making them the default choice for budget-conscious homeowners. Metal roofing represents a significant step up in both price and performance, with systems lasting 40-70 years and offering superior resistance to wind, impact, and fire. Wood shakes or shingles deliver unparalleled natural beauty and excellent insulation properties, but require a lot of maintenance to prevent moisture-related deterioration. Clay or concrete tiles create distinctive architectural statements and have high levels of durability in appropriate climates, though they require structural evaluation to ensure your home can support their substantial weight. Slate represents the premium end of the spectrum, with potential century-long performance for homeowners ready to make a significant financial investment upfront.
The table below shows the cost range you should expect to pay based on the materials you choose.
| Material | Commonality in Homes | Estimated Cost for a 1,100-Square-Foot Home |
|---|---|---|
| Asphalt | 75% | $6,091 |
| Metal | 11% | $11,956 |
| Wood | 7% | $14,854 |
| Clay | 3% | $20,073 |
| Slate | 1% | $20,174 |
Roof Replacement Costs by Region
Where you live matters when it comes to roof replacement costs, thanks to regional variations in labor rates, material availability, climate considerations, and local building codes.
Northeastern homeowners typically face the highest expenses due to a combination of higher labor costs, shorter working seasons, and roofing systems designed to handle significant snow loads and freeze-thaw cycles. Southern states often benefit from more moderate pricing, thanks to longer roofing seasons and less severe winter conditions, though coastal areas may require hurricane-resistant specifications that can increase costs.
Midwest pricing generally falls near the national average, reflecting the region’s balanced labor rates and seasonal constraints. Western states show substantial variation, with coastal areas like California and Washington typically having higher costs due to stringent building codes and labor rates. Meanwhile, inland regions might see more moderate pricing despite often requiring specialized installations for extreme temperature variations.
Here’s what you can expect to spend on your roof replacement by region:
| Region | Cost for a 1,100-Square-Foot Home |
|---|---|
| Northeast | $8,187 |
| South | $8,022 |
| Midwest | $8,168 |
| West | $7,801 |
How Does a Roof Replacement Cost Vary by Home Square Footage?
The relationship between home size and roof costs isn’t strictly linear due to fixed project costs that get distributed differently across varying roof sizes. Smaller roofs often have higher per-square-foot costs because setup expenses, equipment charges, and minimum labor costs are spread across fewer roofing squares. Complexity factors like roof pitch, valleys, and penetrations significantly impact costs beyond simple square footage calculations. Material quantity requirements increase with size but may benefit from bulk pricing on larger projects, creating potential economies of scale.
Based on our math, we’ve found that the cost of a roof replacement increases by about $674 per 100 square feet of living space in a one-story home and $366 per 100 square feet in a two-story home. For every 100 square feet of home, you’ll see roughly an increase of 120 square feet of roof in a one-story home and 60 square feet in a two-story home. This depends on your pitch angle and eaves. For this exercise, we assumed a pitch angle of 6/12 and eaves sticking out 1 foot from the home.
The table below outlines how the cost of your new roof will change based on your square footage.
| Square Footage | Estimated Average Cost |
|---|---|
| 1,000 | $7,251 |
| 1,100 | $7,925 |
| 1,200 | $8,389 |
| 1,300 | $9,045 |
FAQs
What factors might increase my roof replacement cost?
Several factors can increase your roofing costs beyond the standard estimates. Complex roof designs with multiple valleys, dormers, or steep pitches require more labor hours and create more material waste. Removing multiple existing layers of roofing increases labor costs and disposal fees. Replacing damaged roof decking typically adds $50–100 per sheet of plywood. Accessibility issues like limited driveway access or landscaping obstacles that prevent easy ladder placement can add labor time, and roof penetrations, such as skylights, chimneys, and vents, require careful flashing details that can also increase installation time.
Is it better to repair or replace my roof?
The repair-versus-replace decision depends on your roof’s current condition, age, and the extent of damage. Repairs make sense when problems are isolated (a few missing shingles after a storm), the roof is less than 15 years old, and the shingles are still in good condition overall.
Replacement becomes more economical when you’re experiencing multiple leaks, your roof has already undergone several repairs, more than 30% of the roof shows damage, or the existing roof is approaching the end of its expected lifespan. You should also consider how long you plan to stay in your home, because replacement offers peace of mind if you’re planning to remain there for many years.
What should I look for in a roofing warranty?
Focus on both manufacturer and workmanship warranties when evaluating roofing coverage. Manufacturer warranties typically cover material defects for 25–50 years for premium shingles (but may be prorated after the initial period) and rarely cover labor costs after the first few years. More importantly, look for a robust workmanship warranty from your contractor (typically 5–10 years) that covers installation errors, which are often the cause of most roofing problems.
When choosing a roofer and comparing warranties, make sure the warranty transfers to new owners if you sell your home, check what might void warranty coverage (improper ventilation or installation by non-certified contractors), and verify that the company providing the warranty has been in business long enough to suggest they’ll be around to honor it.
How We Calculated Our Roof Replacement Cost Estimates
The cost to replace a roof varies based on a few key factors: the home’s square footage, number of stories, roof pitch, type of roofing material, and pricing in your area.
For each home size, we used calculator.net to calculate a total roof area, using a 6/12 roof pitch with one-foot eave overhangs. The calculation includes a weighted average of one-story versus two-story homes across the United States.
We converted the roof area measurement into “squares” (the roofing industry’s standard unit, with one square covering 100 square feet) to align with how materials are sold and priced. Then we sourced material costs directly from RSMeans data from Gordian®, the industry’s leading construction pricing database used by professional contractors nationwide.
For state averages, we used clark.com to find the median home size in each state. While these figures provide an estimate for budgeting purposes, actual prices vary based on region, specific property characteristics, location, and current market conditions. For the most accurate pricing, we recommend requesting quotes from at least two reputable roofing companies in your area.
