The national average for replacing a roof on a 1,000-square-foot house is between $5,573 and $18,458, depending on factors like the floors in your home, your location, and your roofing material. However, most homeowners spend approximately $7,251 on a roof replacement for a 1,000-square-foot home.
A 1,000-square-foot home will typically have a roof that’s larger than 1,000 square feet due to the pitch of the roof and the eaves that extend beyond the home’s foundation. For a 1,000-square-foot home, you’re looking at approximately 1,279 square feet of roof area for a one-story home or 673 square feet of roof area for a two-story home. Read on to understand more about how these variations can affect the cost of your roof replacement.

Roof Replacement Costs by Story
The number of floors in your home impacts the cost of your roof, as the more stories you have, the smaller the size of your roof. Two-story homes typically have smaller roof footprints than single-story homes of the same square footage, as the living space is stacked vertically rather than spread horizontally. This difference directly impacts material quantities and labor hours. Additionally, multi-story homes often have steeper pitches and more complex roof designs, which can increase installation complexity.
However, since only 5% of homes at 1,000 square feet have two stories, the most likely roof replacement scenario will be for a one-story home. Still, we broke out the estimated roof square footage for both one-story and two-story homes that measure 1,000 square feet, so you could get an idea of costs for both.
| Stories | Est. Roof Square Footage | Average Cost | Cost Range |
|---|---|---|---|
| 1 | 1,279 | $7,427 | $5,709–$18,906 |
| 2 | 673 | $3,908 | $3,004–$9,948 |
Roof Replacement Costs by Material
When selecting your roofing material, you’re making more than just an aesthetic choice—you’re determining your roof’s durability, maintenance needs, and overall value for decades to come. Asphalt shingles remain the most popular choice due to their affordability and reliable performance, making them ideal for budget-conscious homeowners looking for a decent lifespan. Metal roofing offers exceptional longevity and weather resistance at a higher price point, potentially outlasting multiple asphalt roofs. Wood shingles provide natural beauty and insulation but require regular maintenance to prevent moisture damage. Clay tiles offer distinctive style and extreme durability in warmer climates, while slate stands as the premium, most expensive option, but with the possibility of a century-long lifespan.
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 1,000-Square-Foot Home |
|---|---|---|
| Asphalt | 75% | $5,573 |
| Metal | 11% | $10,940 |
| Wood | 7% | $13,591 |
| Clay | 3% | $18,367 |
| Slate | 1% | $18,458 |
Roof Replacement Costs by Region
Where you live has a big impact on the cost of a new roof, with variation stemming from regional labor rates, material availability, and local building code requirements.
The Northeast typically sees higher roofing costs due to stricter building codes, higher labor rates, and the need for roofs that can withstand heavy snow loads and freeze-thaw cycles. Southern states benefit from longer roofing seasons and less stringent winter weather requirements, but may face higher costs for hurricane-resistant installations in coastal areas.
Meanwhile, Midwest homeowners might encounter moderate pricing due to seasonal weather constraints and material transportation costs. Western states show considerable variation, with higher costs in areas like California and Washington due to stricter energy efficiency requirements and seismic considerations. Inland mountain states may require specialized installations for extreme weather conditions.
Here are some average costs for a new roof for a 1,000-square-foot home based on region.
| Region | Cost for a 1,000-Square-Foot Home |
|---|---|
| Northeast | $7,491 |
| South | $7,340 |
| Midwest | $7,473 |
| West | $7,138 |
How Does a Roof Replacement Cost Vary by Home Square Footage?
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.
Understanding how costs scale with square footage helps you anticipate expenses as you consider different home sizes or additions to your existing property. The relationship between home square footage and roofing costs isn’t perfectly linear due to factors like economies of scale in larger projects and the fixed costs associated with roof replacement regardless of size.
Smaller homes often have higher per-square-foot costs because setup, equipment, and minimum labor charges are spread across fewer squares. Complexity factors like roof pitch, number of penetrations, and accessibility can significantly impact costs beyond simple square footage calculations.
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 |
FAQs
How long will roofing installation take?
Replacing a roof on a 1,000-square-foot home typically takes between 1–3 days, depending on several factors. The timeline can vary based on your chosen roofing material: Asphalt shingles might be completed in a single day, while slate or tile could take several days due to their weight and installation complexity. Weather conditions, such as rain, snow, or extreme temperatures, can delay work. Your roof’s complexity, including the number of valleys, dormers, and penetrations, will also extend the timeline. Most professional roofing teams for a home this size consist of 3–5 workers who can remove the old roof and install the new one in just a few days if weather conditions are favorable.
What’s the typical lifespan of a roof?
A roof’s lifespan varies depending on the material you choose and your local climate conditions. Asphalt shingles, the most common roofing material in the US, typically last 15–30 years, with architectural shingles on the longer end of that spectrum. Metal roofs offer significantly more longevity, with properly installed systems lasting 40–70 years. Wood shingles or shakes generally provide 20–30 years of service with proper maintenance. Clay or concrete tiles can protect your home for 50–100 years, while slate roofing is the most durable option, potentially lasting 100+ years if you maintain it. However, these estimates assume proper installation and regular maintenance. Neglecting routine care or installing your roof in extreme climate conditions can significantly reduce these expected lifespans.
How do I know when it’s time to replace my roof?
You should consider replacing your roof when you notice several warning signs that indicate deterioration beyond simple repairs. Missing, cracked, or curling shingles visible from the ground suggest that your roofing material is failing. Water stains on your ceilings or walls often indicate leaks that have penetrated through the roof structure.
Plan to check your gutters for excessive granule loss from asphalt shingles, which signals advanced wear. A sagging roofline could suggest potential structural damage that you should address immediately. Daylight visible through roof boards in your attic indicates holes or severe deterioration. Age is also a reliable indicator, so if your asphalt roof is approaching 20 years or has already exceeded it, contact a professional for an evaluation, even if you don’t notice visible problems.
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.
