Roof Replacement Costs by Home Stories
The number of stories in your home affects roof replacement costs by determining the total roof area requiring new materials and installation. Two-story construction stacks living space vertically rather than spreading it horizontally, reducing the required roof area by nearly half. The table below shows the price range based on your home’s story configuration.
| Stories | Estimated Roof Square Footage | Average Roof Replacement Cost | Roof Replacement Cost Range |
|---|---|---|---|
| 1 | 4,730 | $27,467 | $21,112–$69,918 |
| 2 | 2,413 | $14,012 | $10,770–$35,669 |
A one-story, 3,900-square-foot home needs approximately 4,730 square feet of roofing coverage, while a two-story home requires only 2,413 square feet. According to our data, 99% of 3,900-square-foot homes feature two-story construction, which means if your home is this size, it’s probable you have two stories. The reduced roof area directly translates to lower material expenses, shorter installation periods, and decreased labor costs for significant overall project savings. Use the calculator tool below to estimate costs based on your home’s configuration.

Your roofing material choice represents the main factor determining your total project cost. Each material provides distinct performance capabilities and characteristics, and each features a different price point. Asphalt shingles are the most popular option, as they’re affordable and durable. Metal roofing is next in line, particularly appealing to homeowners in severe weather regions or those prioritizing long-term durability over initial cost considerations. Premium materials, including wood shakes, clay tiles, and slate, serve specialized markets with longevity and distinctive architectural appeal. The table below shows estimated costs for each major roofing material on a 3,900-square-foot home.
| Roofing Material | Commonality in Homes | Estimated Roof Replacement Cost for a 3,900-Square-Foot Home |
|---|---|---|
| Asphalt | 75% | $10,874 |
| Metal | 11% | $21,343 |
| Wood | 7% | $26,516 |
| Clay | 3% | $35,832 |
| Slate | 1% | $36,011 |
Roof Replacement Costs by Region
Regional disparities in pricing come from varying labor rates, material transportation costs, local building code requirements, seasonal demand patterns, and market dynamics among contractors. The Northeast consistently has the highest average costs due to elevated wage scales, more stringent building codes, and specialized requirements for harsh winter weather conditions. Southern markets provide more competitive pricing through year-round construction seasons and lower labor costs, though hurricane-resistant building requirements in coastal areas can offset some regional cost advantages.
Midwestern pricing generally occupies the moderate middle range, influenced by seasonal construction limitations and the necessity for materials capable of handling extreme temperature variations between seasons. Western markets demonstrate dramatic cost variations, with premium urban locations charging significantly higher prices while rural areas may offer more competitive rates. The table below shows average costs by major U.S. regions for a 3,900-square-foot home.
| Region | Roof Replacement Cost |
|---|---|
| Northeast | $14,615 |
| South | $14,321 |
| Midwest | $14,580 |
| West | $13,926 |
How Does Roof Replacement Cost Vary by Home Square Footage?
The relationship between square footage and roofing costs isn’t perfectly linear due to roof complexity factors, architectural features, and penetrations requiring specialized installation techniques. Larger homes often benefit from economies of scale on fixed costs like permits and equipment mobilization, but may incorporate premium materials or complex architectural designs that increase per-square-foot expenses. These scaling factors apply to typical residential construction with standard roof pitches, though unique architectural elements can significantly impact baseline cost calculations.
We did the math and 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 example, we assumed a pitch angle of 6/12 and eaves sticking out 1 foot from the home. The table below shows cost changes based on square footage in the range surrounding 3,900 square feet.
| Home Square Footage | Estimated Roof Replacement Cost |
|---|---|
| 3,700 | $13,443 |
| 3,800 | $13,795 |
| 3,900 | $14,147 |
| 4,000 | $14,498 |
| 4,100 | $14,850 |
FAQs About Replacing a Roof on a 3,900-Square-Foot House
How long will roofing installation take for a 3,900-square-foot home?
A roof replacement on a 3,900-square-foot home typically takes 4–9 days, depending on factors such as the weather, roof design, and material choice. Contractors can install asphalt shingles faster than heavier options like slate or tile, and the crew’s size and experience can also affect timing. Needing unexpected structural repairs may add extra days to the process.
What’s the typical lifespan of a roof?
The lifespan of a roof depends on the material and environment. Asphalt shingles usually last 20–30 years, while wood shakes need routine upkeep to reach the same. Metal roofs can last 40–70 years, clay or concrete tiles often reach 50–100, and slate is the most durable option, protecting homes for over a century.
How do I know when it’s time to replace my roof?
You may need to replace your roof if it’s over 20 years old or showing signs of wear. Common warning signs include missing or damaged shingles, bald spots from granule loss, water stains on ceilings, or sagging rooflines. You might also notice granules collecting in your gutters, higher energy bills, or moss and algae spreading across large areas.
Should I replace my roof myself or hire a professional?
Roof replacement is not typically considered a good do-it-yourself (DIY) project. The work is dangerous, requires specialized safety equipment, and involves handling heavy materials at significant heights. Professional roofers are knowledgeable about building codes, ventilation requirements, and waterproofing techniques to ensure long-term protection. Contractor work is also insured, comes with labor warranties, and keeps your manufacturer and homeowners insurance coverage intact.
How We Get Our Roofing Cost Data
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.
