Instantly see your total price range, cost per square foot and a line-by-line breakdown of materials, labor and tear-off — then request free quotes to confirm.
Each estimate begins with up-to-date installed pricing for your chosen material, then applies the cost drivers that most influence the final figure — roof pitch, tear-off, and access or number of stories. Results are shown as a range because no two roofs are alike: the lower figure reflects a simple, single-story roof in a lower-cost region, while the higher figure reflects a steep, multi-story roof with premium materials and a full tear-off.
Most projects fall near the middle, which we display as your estimated total. For a firm price, we recommend confirming with a licensed local roofer who can inspect your roof deck and existing shingles in person.
Typical installed price per square foot (materials + labor) for a residential roof replacement in the U.S. Your final cost depends on roof size, pitch, tear-off, access and local labor rates.
| Roofing Material | Installed $/sq ft | Lifespan | Best For |
|---|---|---|---|
| Asphalt (3-tab) | $3.50 – $5.50 | 15–20 yrs | Budget-friendly replacements |
| Architectural shingle | $4.50 – $8 | 25–30 yrs | Most homes — best all-round value |
| Metal (standing seam) | $9 – $16 | 40–70 yrs | Longevity, storms & energy savings |

The material you choose is the single biggest factor in your roof replacement cost and how long the roof lasts. Here's how the most common U.S. roofing systems compare.
Traditional 3-tab asphalt shingles are the most affordable roofing option and still the fastest to install. They give a clean, flat appearance and suit rental properties or homeowners who need a reliable roof at the lowest upfront price.
The trade-off is a shorter lifespan and lighter wind rating than upgraded shingles, so many homeowners now step up to architectural shingles for only a little more.
Architectural (dimensional) shingles are now the industry standard. They're thicker and layered for a richer, textured look, carry longer warranties, and handle high winds far better than 3-tab.
For most homeowners they hit the sweet spot of price, durability and curb appeal, which is why they're the default recommendation on the majority of pitched roofs.
Standing seam metal roofing costs more upfront but can outlast two or three shingle roofs. Concealed fasteners and interlocking panels shed water, snow and wind exceptionally well, and reflective finishes cut summer cooling bills.
It's a strong long-term value for homeowners staying put, and increasingly popular in wildfire and hurricane regions for its durability and fire resistance.
Tile delivers a distinctive, premium look and one of the longest lifespans of any roof — often outliving the house itself. It excels in hot, dry and coastal climates and resists fire and rot.
Tile is heavy, so the roof structure must be able to carry it, and installation is specialized — both of which push it to the top of the price range.
Flat and low-slope roofs use single-ply membranes like EPDM, TPO and PVC rather than shingles. They're common on modern homes, extensions, garages and commercial buildings where the roof pitch is minimal.
Need a detailed flat-roof estimate? Use our dedicated Flat Roof Calculator for material-by-material pricing on EPDM, TPO, PVC and more.
The best membrane depends on your climate, budget, roof traffic and how long you plan to stay. Get matched with vetted local pros who can inspect your roof and recommend the right system.
Two roofs of the same size can differ by thousands of dollars. These are the factors our calculator accounts for — and the ones your contractor will price.
| Cost factor | How it affects your quote | Price impact |
|---|---|---|
| Material choice | Premium materials like metal and tile cost far more per square foot than asphalt shingles — but last decades longer. | High |
| Roof size & shape | Bigger roofs cost more in total but less per square foot. Odd shapes and many penetrations add labor hours. | High |
| Tear-off & disposal | Removing and hauling away the old roof adds roughly $1–$2 / sq ft. Overlays are cheaper, but not always allowed by code. | Medium |
| Roof pitch & complexity | Steep roofs and complex shapes — dormers, valleys, hips and multiple penetrations — take more material and labor hours. | Medium |
| Underlayment & flashing | New underlayment, drip edge, and valley or chimney flashing add cost but are what actually keep the roof watertight. | Low |
| Access & height | Multi-story roofs, poor access and scaffolding or safety requirements all increase labor charges. | Medium |
| Your location | Local labor rates, permit fees and building codes vary by city and state, moving the total up or down. | Medium |
| Deck repairs | Rotted decking or structural fixes discovered during tear-off are billed on top of the base price. | Varies |
Caught early, some roof issues are cheap repairs. Left too long, they mean a full replacement. Watch for these warning signs.
Water stains on ceilings or walls after rain mean moisture is already getting past the roof.
Shingles that are curling, buckling, cracked or missing leave the roof deck exposed to the weather.
Bare patches and granules collecting in your gutters mean the shingles are near the end of their life.
Light coming through the roof boards, or damp insulation, points to gaps and active leaks overhead.
A drooping or uneven roofline signals a weakened or water-damaged deck that needs prompt attention.
Most roofs last 20–30 years. If yours is near the end of its life, replacing usually beats repeated repairs.

Most roof replacements cost between $4 and $18 per square foot installed. A typical asphalt-shingle roof runs about $8,000–$18,000, while premium metal or tile roofs can reach $25,000–$45,000. Your exact price depends on the material, roof size, pitch, tear-off and local labor rates.
Multiply your building's length × width in feet to get the footprint, then multiply by a pitch factor (about 1.05 for low-slope, 1.2 for a typical roof, 1.4 for steep) to estimate the true roof area. Our calculator does this automatically once you enter your building dimensions and pitch.
3-tab asphalt shingles are the most affordable at about $3.50–$5.50 per square foot installed. Architectural shingles cost a little more but last longer and resist wind better, which is why most homeowners choose them over 3-tab today.
Metal costs more upfront ($9–$16 per sq ft) but can last 40–70 years — two to three times a shingle roof — while shrugging off wind, snow and fire and cutting cooling bills. If you plan to stay in the home long-term, the lifetime cost often works out lower.
It depends on the material: asphalt shingles last 15–30 years, metal 40–70 years, and clay or concrete tile 50+ years. Good installation, ventilation and regular maintenance all add years to any roof.
Isolated leaks or a few missing shingles are usually worth repairing. But if the roof is near the end of its life, has widespread damage, or the deck is compromised, replacement is the better long-term value — repeated repairs on an old roof rarely pay off.
Yes. Removing and disposing of the old roof typically adds about $1–$2.50 per square foot. Some codes allow a new layer over the old one (an overlay), which is cheaper — but a tear-off lets the crew inspect and repair the deck, so it's usually worth it.
