Roof Replacement Cost Guide 2026: Asphalt, Metal & Tile

A roof replacement is the largest single purchase most homeowners make for a house they already own. The national average for a tear-off and re-roof sits between $9,000 and $17,000, and the material you choose can push that number up or down by tens of thousands. Two identical houses on the same street can get quotes $20,000 apart, and the gap almost never comes down to greed. It comes down to what the roof is made of, how hard it is to reach, and what has to be torn off before the new one goes on. > **Start with your roof size:** Use our [free roofing calculator](/roofing-calculator/), enter house dimensions and roof pitch to get squares, bundles, and a materials cost estimate in seconds. --- ## What a Roof Replacement Costs in 2026 Roofing is priced by the square, a unit equal to 100 square feet of actual roof area. A typical single-family home has 20 to 30 squares, and every estimate you receive is built on that count plus the material price per square. Here is where the numbers land in 2026 for a 20-square roof. | Material | Material per Square | Installed per Square | 20-Square Roof Installed | |------|:--:|:--:|:--:| | **3-tab asphalt** | $80-100 | $300-450 | $6,000-9,000 | | **Architectural asphalt** | $120-180 | $350-550 | $7,000-11,000 | | **Exposed-fastener metal** | $250-450 | $700-1,100 | $14,000-22,000 | | **Standing-seam metal** | $400-800 | $900-1,500 | $18,000-30,000 | | **Concrete tile** | $600-900 | $800-1,400 | $16,000-28,000 | | **Clay tile** | $800-1,200 | $1,000-1,600 | $20,000-32,000 | The spread inside each row is real. It reflects where you live, how steep the roof is, and how many layers of old shingles have to come off first. The spread between rows, the jump from a $9,000 asphalt job to a $30,000 metal one, is the material decision. That is the number you control most directly. ## The Three Cost Drivers Almost every dollar in a roof quote traces back to one of three things. ### 1. The Material Shingles, metal panels, and tile all carry wildly different price tags, and each needs different fasteners, underlayment, and labor. Material is roughly 30 percent of an asphalt roof's installed cost but closer to half of a metal or tile roof's. The rest of this guide breaks the three main families down in detail. ### 2. Size, Pitch, and Shape A steep roof has more surface area than the flat footprint of the house below it, and more surface means more material. A 6/12 pitch adds about 12 percent to the footprint. A 12/12 pitch adds 41 percent. Complex shapes, hips, valleys, dormers, drive the waste factor up too. A simple gable might need 10 percent extra shingles for cuts, a cut-up roof with dormers needs 20 percent. Every cut is a place a roofer spends time, so complexity costs labor on top of material. ### 3. Labor and Access Roofing is one of the most physically demanding trades, and it carries one of the highest injury rates. A crew working a low, walkable 4/12 roof moves fast. The same crew on a 10/12 pitch moves at half speed, tied off and working on roof jacks. Height, steepness, and how many stories the crew has to haul materials up all get priced into the labor line. A two-story house adds 10 to 15 percent over a single-story ranch with the same roof area. ## Asphalt vs Metal vs Tile ### Asphalt Shingles Asphalt is the default for most of North America for a reason. It is the cheapest material, the fastest to install, and every roofer knows how to work with it. **3-tab shingles** are the budget option. Flat, uniform, and thin, they last 15 to 20 years and are being phased out in favor of their thicker cousins. You still see them on rental properties and starter homes where price is the whole decision. **Architectural shingles** are the new standard. Two layers of material give them a textured, dimensional look and a 30 to 50 year warranty, and they cost only 30 to 50 percent more than 3-tab. Wind ratings run 110 to 130 mph. For most homeowners this is the value pick, the sweet spot between upfront cost and years before the next re-roof. ### Metal Roofing Metal splits into two camps that get confused constantly. **Exposed-fastener metal** uses panels screwed straight through the face. It is cheaper, faster, and common on barns, shops, and low-slope residential work. The screws have rubber washers that eventually dry out and leak, so it needs inspection every decade or so. **Standing-seam metal** uses hidden clips and folded seams, no exposed fasteners at all. It is the premium option, 50 years or more of life, excellent wind and hail resistance, and it reflects heat in a way asphalt never will. The tradeoff is the installed cost, two to three times an asphalt roof, and the fact that it is not a DIY or weekend-crew job. The panels are fabricated on site to the exact roof measurements. Metal makes the most sense when you plan to stay in the house for decades and can earn back the premium over two or three asphalt lifespans. ### Clay and Concrete Tile Tile is the look of the Southwest and Mediterranean, and it is the most durable roofing on this list at 75 to 100 years. Concrete tile runs cheaper than clay, but both are heavy, 600 to 1,000 pounds per square. An existing roof structure often needs reinforcement before tile can go on, and that engineering and framing work is a line item all its own. In a warm, dry climate tile will outlive the house. In a freeze-thaw climate it costs a fortune and holds ice, so it is rarely the right call outside the Sun Belt. ## How Pitch and Size Turn Into Square Count Before you can compare any of those material prices, you need your square count, and that starts with the footprint, not the roof itself. Measure the length and width of the house at ground level. Multiply for the footprint. Then apply the pitch factor, which converts that flat footprint into actual roof surface area. | Pitch | Factor | Effect | |------|:--:|------| | 4/12 | 1.054 | Roof is 5.4% larger than footprint | | 6/12 | 1.118 | +11.8% | | 8/12 | 1.202 | +20.2% | | 10/12 | 1.302 | +30.2% | | 12/12 | 1.414 | +41.4% | A 40 by 30 foot ranch has a 1,200 square foot footprint. At a 6/12 pitch that is 1,200 × 1.118 = 1,342 square feet of roof, or 13.4 squares. Add 15 percent waste for a hip roof and you buy about 16 squares. At $35 to $45 a bundle and three bundles per square, materials alone land near $1,700 to $2,200. The [roofing calculator](/roofing-calculator/) runs this whole chain for you, from footprint through pitch to squares and bundles. ## Where the Money Goes: Materials, Labor, and Extras An asphalt re-roof is not mostly shingles. The shingles are the visible third. The rest of the check pays for what you never see. Labor is the biggest single line, 40 to 50 percent of the total. Tear-off of the old roof runs $1 to $2 per square foot. The new underlayment, fasteners, drip edge, flashing, and ventilation run another 10 to 15 percent. Overhead, profit, insurance, and the crew's liability coverage fill out the remainder. On a metal or tile roof the material share rises because the panels and tile themselves are so expensive, and the specialized installers charge more. Then come the extras that no quote includes until someone looks under the old shingles. ## Hidden Costs That Show Up After the Quote A contractor writes the quote before anyone can see the roof deck. These are the lines that get added once the old roof is off. **Decking replacement.** Rotted or delaminated plywood and OSB must come out. The national average is about $70 to $100 per 4 by 8 sheet, and a full redeck can add thousands. **Underlayment.** Modern synthetic underlayment runs $15 to $20 per square. Cheap quotes sometimes spec a single layer of old #30 felt at $8 to $10. The upgrade is worth it, synthetic tears less and seals better around nails. **Ice and water shield.** In cold climates, code requires a self-sealing membrane along the eaves and in valleys. It runs $60 to $90 a roll and is not optional where it is mandated. **Flashing and drip edge.** Reusing old flashing is a false economy, and any roofer worth hiring replaces it. Figure a few hundred dollars for the metal around chimneys, walls, and valleys. **Permits and disposal.** A permit runs $100 to $500 depending on the town. Dumpster and debris hauling run $300 to $500. A second layer torn off an old house doubles the disposal. **Steep and tall surcharges.** Pitch above 8/12 and roofs over two stories carry an upcharge of 5 to 15 percent for the slower, riskier work. A honest quote lists these as line items or states clearly which are included. A vague one hides them and collects them as change orders later. ## Replace vs Repair: When a Patch Is Enough Not every leak means a full replacement. The age and spread of the damage decide it. Repair makes sense when the roof is under 15 years old, the damage is isolated to one storm hit or a single failed flashing, and the shingles across the rest of the roof are still intact. Replace when the roof is past 20 years, shingles are curling or cracking in multiple areas, granules show up in the gutters every season, or you find soft spots when walking the deck. The "2 in 10" test is the fastest read. If more than two out of every ten shingles in a representative area show curling, cracking, or missing tabs, you have reached the end of the roof, and patching is just spending money on the way to a replacement. ## How to Read a Quote Without Getting Burned Get at least three written quotes and compare them line by line, not by the bottom number. Make sure every quote specifies the same material, the same underlayment, and the same scope. Tear-off, disposal, flashing, permits, and decking allowance should all be named. Check the warranty separately, the material warranty comes from the manufacturer, the workmanship warranty from the roofer, and a long material warranty means nothing if the installer disappears in two years. Ask whether the roofer is licensed and insured in your state, and whether they will pull the permit, not you. The lowest bid is usually low because it left something out, and that something gets billed to you later. ## 5 Roof Replacement Mistakes ### 1. Choosing Price Over Lifespan A 3-tab roof at $6,000 looks cheap until it needs replacing again in 15 years, at which point the architectural roof you could have bought once would still have half its life left. Divide the installed price by the expected years, and the cheapest bid often has the worst cost per year. Buy the roof you will still be happy with in year 20. ### 2. Keeping the Old Flashing Flashing is the metal where the roof meets a chimney, wall, or valley, and it is where roofs leak first. The temptation is to save a few hundred dollars and reuse it. Old flashing is bent, corroded, and sealed with old caulk. It fails and lets water into a brand new roof. Replacing it is one of the cheapest lines on the quote and one of the most important. ### 3. Nailing a Second Layer Over the First Most codes allow one re-roof over an existing shingle layer. It saves the tear-off cost. It also hides the deck rot, traps heat that shortens the new shingles' life, and adds weight the structure may not be rated for. A second layer is a temporary roof wearing a warranty. Do the tear-off. ### 4. Skipping Ventilation A new roof with no attic ventilation cooks from underneath. Heat trapped under the deck bakes the shingles and shortens their life, and moisture rots the deck. A balanced system, intake at the soffits and exhaust at the ridge, about 1 square foot of vent area per 150 square feet of attic, is a small line item that protects the whole investment. ### 5. Hiring the Quote, Not the Roofer The cheapest bid often comes from an unlicensed crew that is gone by the time the first leak appears, and there is no workmanship warranty to call on. Check the license, the insurance, and the references. A roof that fails is the most expensive roof of all, because you pay for it twice. --- Ready to price your roof?
