Roof Replacement Costs by Story
The more stories you have in your home, the lower the size of your roof. Roughly 50% of homes at 1,700 square feet have two stories, so there is an even mix between one-story and two-story homes in the country.
This equal distribution makes sense at this size point, as many homes in this square footage range are built in either ranch-style (single-story) or colonial/traditional (two-story) designs. The different roof requirements explain why costs vary so dramatically between these two common building styles. Contractors calculate materials in “squares” (100 square feet), so a one-story 1,700-square-foot home might require 21+ squares of material, while its two-story counterpart needs only about 11 squares.
For instance, a one-story home at 1,700 square feet will have roughly 2,112 square feet of roof area vs. a two-story home, which has generally half that amount.
| Stories | Est. Roof Square Footage | Average Cost | Cost Range |
|---|---|---|---|
| 1 | 2,112 | $12,264 | $9,427–$31,219 |
| 2 | 1,093 | $6,347 | $4,878 –$16,157 |
Roof Replacement Costs by Material
Your roofing material selection represents one of the most significant cost variables when replacing your roof on a 1,700-square-foot home. Your selection should balance immediate budget constraints against long-term ownership plans, climate considerations, and architectural compatibility.
Asphalt shingles continue to dominate residential roofing, offering a balance of affordability and decent durability that appeals to most homeowners working within typical budgets. However, metal roofing has gained significant market share in recent years as homeowners increasingly prioritize longevity and energy efficiency, despite higher upfront costs. Wood roofing maintains a smaller but dedicated following, primarily among those seeking specific aesthetic qualities or historic authenticity. Premium materials like clay and slate represent luxury choices that substantially increase your initial investment but could potentially eliminate the need for future replacements over a home’s lifetime.
| Material | Commonality in Homes | Estimated Cost for a 1,700-Square-Foot Home |
|---|---|---|
| Asphalt | 75% | $7,153 |
| Metal | 11% | $14,039 |
| Wood | 7% | $17,442 |
| Clay | 3% | $23,570 |
| Slate | 1% | $23,688 |
Roof Replacement Costs by Region
Geographic location plays a substantial role in determining the cost of a new roof on a 1,700-square-foot home. Regional price differences stem from variations in labor costs, material availability, local building codes, and climate-related installation requirements across the country.
Northeastern homeowners typically face the highest costs due to a combination of higher labor rates, more stringent building codes, and a compressed roofing season that affects contractor scheduling. Southern states often enjoy more competitive pricing thanks to year-round installation conditions and generally lower labor costs. Midwestern pricing typically falls between these extremes, reflecting moderate labor rates balanced against seasonal limitations. Western region costs can vary significantly depending on exact location, with coastal and urban areas commanding premium rates compared to inland locations. These regional factors explain why national averages might not perfectly reflect pricing in your specific location.
| Region | Cost |
|---|---|
| Northeast | $9,613 |
| South | $9,420 |
| Midwest | $9,590 |
| West | $9,160 |
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. 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 for every 100 square feet of home.
However, 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. These proportional relationships help explain why roofing costs don’t increase exactly linearly with home size. The roof-to-floor-area ratio varies based on architectural style and story count, which impacts material requirements and installation complexity. Knowing more about these scaling factors can help you better contextualize contractor quotes and compare estimates when researching your roofing project.
The table below outlines how the cost of your new roof will change based on your square footage.
| Square Footage | Estimated Cost |
|---|---|
| 1,500 | $9,313 |
| 1,600 | $9,343 |
| 1,700 | $9,306 |
| 1,800 | $9,199 |
| 1,900 | $9,685 |
FAQs
How do warranties differ between roofing materials?
Roofing warranties vary significantly by material and manufacturer. Asphalt shingles typically offer 25 or 30-year manufacturer warranties for material defects, though premium lines may extend to 50 years or “lifetime” coverage. These warranties usually decrease in value over time and rarely cover labor costs after the initial years.
Metal roofing warranties are often more robust, typically ranging from 30–50 years, with some premium systems offering non-prorated lifetime coverage that can transfer to subsequent homeowners. Premium materials like slate and clay tile often come with the strongest warranties (50+ years or lifetime), which reflect their exceptional durability. Beyond manufacturer coverage, reputable contractors typically provide separate workmanship warranties (typically 5–10 years) covering installation defects. Always review warranty terms carefully for coverage exclusions, transferability limitations, and maintenance requirements.
What’s involved in a roof replacement project?
The roof replacement process begins with thorough inspection and measurement, followed by material selection and ordering. On installation day, the crew first protects your landscaping and property, then removes existing roofing materials down to the decking. They’ll inspect and repair any damaged decking, install new underlayment and water barriers, and then apply your chosen roofing material. They might replace or install flashing around roof penetrations and in valleys.
After installation, crews perform a thorough cleanup using magnetic tools to collect nails and debris, followed by a final inspection to ensure proper installation and appearance. Depending on your roof size and complexity, the actual installation typically takes 1–3 days once materials have been delivered.
How do I choose the right roofing contractor?
Select a reliable roofing contractor by verifying their proper licensing, insurance (liability and workers’ compensation), and established local presence. Request and contact references from recent projects similar to yours—asking friends or neighbors who have houses similarly sized to your 1,700-square-foot home may help.
Compare at least three detailed, written estimates that break down materials, labor, and specific work to see what each includes. Verify manufacturer certification and warranties (both material and workmanship), discuss project timelines and payment schedule (avoid large upfront payments), and ask about cleanup procedures.
Prioritize value over the lowest bid, as quality installation significantly impacts your roof’s performance and lifespan. Finally, trust your interaction experience—responsive, clear communication during the estimate process typically indicates professional project management.
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.
