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. A typical 1,400-square-foot home with one story will require more roofing materials than a home of the same size with two stories, which explains the significant cost difference.
Let’s use an example for clarity: A one-story home at 1,400 square feet will have roughly 1,755 square feet of roof area. On the other hand, a two-story home generally has about half that amount. Approximately 20% of homes at 1,400 square feet have two stories, so you’re more likely to have a one-story home at this house size.
When contractors calculate your roof replacement cost, they measure your actual roof square footage, not your home’s floor area. Understanding this distinction helps explain why identically sized homes might receive different roofing quotes. This calculation considers everything from your roof’s pitch to additional features like dormers and overhangs.
| Stories | Est. Roof Square Footage | Average Cost | Cost Range |
|---|---|---|---|
| 1 | 1,755 | $10,191 | $7,833 – $25,942 |
| 2 | 913 | $5,302 | $4,075 – $13,496 |
Roof Replacement Costs by Material
Your choice of roofing material can dramatically change your new roof’s upfront cost and long-term value. Asphalt shingles remain the most popular choice nationwide due to their affordability and reasonable durability, representing approximately 75% of residential roofs in America.
Metal roofing, while more expensive initially, offers exceptional longevity that can offset the higher upfront investment over time. Specialty materials like wood, clay, and slate deliver distinctive aesthetic appeal and premium performance at considerably higher prices. Each material comes with its own installation requirements, maintenance needs, and expected lifespan, making this decision about more than just immediate cost concerns. Your local climate, home style, and how long you plan to stay in your home should all factor into selecting the right material for your 1,400-square-foot home’s roof replacement.
| Material | Commonality in Homes | Estimated Cost for a 1,400-Square-Foot Home |
|---|---|---|
| Asphalt | 75% | $7,082 |
| Metal | 11% | $13,900 |
| Wood | 7% | $17,269 |
| Clay | 3% | $23,337 |
| Slate | 1% | $23,453 |
Roof Replacement Costs by Region
While researching roofing costs, we found that geographic location plays a significant role in determining what you’ll pay for a new roof on your 1,400-square-foot home. This regional variance stems from several factors, including local labor rates, building code requirements, and climate considerations specific to different parts of the country. Understanding these regional differences helps you set realistic expectations for your roofing project and explains why national averages might not perfectly reflect local market conditions.
In the Northeast, contractors often charge more due to stricter building codes and weather challenges, while Southern states may offer more competitive pricing due to year-round roofing seasons. Midwestern homeowners typically face moderate pricing influenced by seasonal constraints and average labor costs. Western states show variation depending on specific location, with coastal areas generally commanding premium rates compared to inland regions.
| Region | Cost |
|---|---|
| Northeast | $9,518 |
| South | $9,327 |
| Midwest | $9,495 |
| West | $9,069 |
How Does a Roof Replacement Cost Vary by Home Square Footage?
Based on our math, we’ve found that a roof replacement costs 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 relationship between your home’s floor space and roof size isn’t perfectly proportional due to roof pitch, overhangs, and architectural features. Understanding these scaling factors helps you estimate how costs might change if your home is slightly larger or smaller than the standard measurements. Contractors calculate materials in “squares” (100 square feet of roofing area), and knowing how your home’s dimensions translate to roofing squares gives you better insight into pricing variations.
The table below outlines how the cost of your new roof will change based on your square footage.
| Square Footage | Estimated Cost |
|---|---|
| 1,200 | $8,389 |
| 1,300 | $9,045 |
| 1,400 | $9,213 |
| 1,500 | $9,313 |
| 1,600 | $9,343 |
FAQs
How long will roofing installation take?
The installation of a new roof on a 1400-square-foot home typically takes 1–3 days to complete, depending on several factors. Weather conditions, such as rain or extreme temperatures, can delay the process.
The complexity of your roof design also matters. Homes with multiple levels, dormers, skylights, or steep pitches require more time than simple gable roofs. Your chosen roofing material also affects the timeline. Asphalt shingles are the quickest to install (often just 1–2 days for a straightforward, 1,400-square-foot house), while slate or tile installations might extend to 4–5 days due to the materials’ weight and installation requirements.
Most professional roofing crews consist of 4–6 workers who work systematically across your roof, removing old materials (if necessary), installing underlayment, and finally applying the new roofing material. Some companies may assign larger crews to complete the job more quickly, particularly if weather challenges are involved.
What’s the typical lifespan of a roof?
The lifespan of your new roof tends to change based on the material you choose. Asphalt shingles, the most common and affordable option, typically last 15–30 years, with 3-tab shingles on the lower end and architectural shingles on the higher end. Metal roofing offers substantially more extended protection, with a lifespan of 40–70 years for steel or aluminum, while premium copper or zinc roofs can last a century or more with proper maintenance.
Wood shakes and shingles generally provide 20–30 years of service, though this can vary based on your local climate, with dry regions extending lifespan and humid areas potentially shortening it. Clay and concrete tiles offer exceptional durability, lasting 50–100 years, with quality clay tiles potentially exceeding a century of protection. Slate is the longest-lasting option, possibly up to 100+ years—many historic homes are still protected by their original slate roofs.
Beyond material choice, your roof’s longevity can vary due to installation quality, local climate conditions, maintenance practices, and ventilation systems.
How do I know when it’s time to replace my roof?
Several clear warning signs indicate it’s time to replace your roof rather than simply repair it. Missing, loose, or damaged shingles are obvious red flags—look for bald spots where granules have worn away on asphalt shingles, or shingles that have cracked, curled, or buckled. Water stains on your ceilings or walls often indicate active leaks that have penetrated through roofing materials and underlayment. Any sagging in your roof deck requires immediate professional evaluation, as this could signal structural damage or prolonged water infiltration, causing rot.
Excessive moss, algae, or mold growth often indicates moisture retention issues that accelerate roof deterioration. If you’ve noticed your energy bills climbing without explanation, your roof may no longer provide proper insulation or ventilation. Age alone is a significant factor. If your asphalt roof is 15–20+ years old, it’s approaching the end of its expected lifespan even without apparent damage. When multiple repair issues arise simultaneously, or if your roof has endured several major storms, replacement often proves more cost-effective than ongoing repairs to an aging system.
How We Calculated Our Roof Replacement Cost Estimates
The cost to replace a roof varies based on four primary factors: the home’s square footage, number of stories, roof pitch, and type of roofing material.
The cost to replace a roof varies based on four primary factors: the home’s square footage, number of stories, roof pitch, and type of roofing material.
For each home size, we applied standard architectural principles to determine the total roof area—a 6/12 roof pitch (rising 6 inches vertically for every 12 inches horizontally) with one-foot eave overhangs. The calculation also incorporates weighted averages reflecting the distribution 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 vendors sell and price materials. Material costs were sourced directly from RSMeans data from Gordian®, the industry’s leading construction pricing database used by professional contractors nationwide.
The final cost estimates represent the number of required squares multiplied by the material cost per square. While these figures provide a reference point for budgeting purposes, actual prices may 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.
