The Short Answer: Roof Replacement Cost in October 2026
Roof replacement is priced by the square, 100 square feet of roof surface, and in October 2026 a standard architectural asphalt shingle roof runs about $450 to $650 per square fully installed, based on published Angi, HomeAdvisor and roofing industry cost surveys. For the most common US roof sizes, 17 to 25 squares, that is roughly $8,000 to $16,000 for the roof most homes get. Metal, tile and slate climb from there, steeply. This guide shows where the money goes, what a square of each material costs, and how pitch, layers and region move your number, so a quote reads like a document instead of a mystery.
Cost Per Square by Material
| Material | Installed cost per square | Typical 20 square roof | Expected life |
|---|---|---|---|
| Three tab asphalt shingles | $350 to $500 | $7,000 to $10,000 | 15 to 20 years |
| Architectural asphalt shingles | $450 to $650 | $9,000 to $13,000 | 25 to 30 years |
| Metal (standing seam or panels) | $900 to $1,600 | $18,000 to $32,000 | 40 to 70 years |
| Wood shingles and shakes | $700 to $1,100 | $14,000 to $22,000 | 25 to 35 years |
| Concrete or clay tile | $1,000 to $1,800 | $20,000 to $36,000 | 50+ years |
| Slate | $1,500 to $3,000 | $30,000 to $60,000 | 75 to 100+ years |
Source note: installed ranges compiled October 2026 from published national cost surveys (Angi, HomeAdvisor) and roofing trade pricing summaries. Tile and slate assume a structure rated for the weight; structural reinforcement, where needed, is extra and common on homes built for shingles.
Where the Money Goes on a Shingle Roof
| Component | Share of a typical quote | What it covers |
|---|---|---|
| Shingles and accessories | About 35 to 40 percent | Shingles, starter strip, ridge cap, vents |
| Labor | About 40 to 45 percent | Tear off crew and install crew |
| Underlayment and ice shield | About 5 to 8 percent | Synthetic felt, ice and water membrane |
| Tear off and disposal | About 8 to 12 percent | Dumpsters and landfill fees, $50 to $100 per square |
| Flashing and drip edge | About 3 to 6 percent | Metal at chimneys, valleys, walls and eaves |
| Permits and miscellaneous | About 1 to 3 percent | Permit fees, delivery, site protection |
Two lines deserve suspicion when they are missing from a low quote. Decking repair is the first: rotted or delaminated plywood is only visible after tear off, and honest quotes price it per sheet, commonly $70 to $120 per sheet installed, stated in advance. Flashing is the second. Reusing 25 year old flashing under a 30 year roof is a leak scheduled for year eight. If a quote is silent on both, it is not cheaper, it is unfinished.
The Factors That Move Your Price
Pitch and complexity
Pitch multiplies everything. A walkable 4/12 roof is the baseline. At 8/12 the crew works slower with more safety gear, and past 10/12 the job is a different trade day entirely. Each valley, dormer, chimney and intersecting roof plane adds flashing work and waste. A simple gable roof and a cut up roof of the same area can differ by 20 to 30 percent in labor alone, which is why per square averages only get you into the right neighborhood, never to the final number.
Layers and tear off
Every existing layer costs money to remove and dump. Two layers can add $100 to $180 per square over a single layer tear off. Ask how many layers you have before you budget: a home that has been re roofed once by layover carries the cost forward to you, with interest.
Region and season
Labor is the swing factor, and it tracks local wages. Expect quotes in the Northeast and West Coast metros to run 20 to 40 percent above the national middle, and rural South and Midwest quotes to run 10 to 20 percent below. Season matters at the edges: roofers in cold climates discount late fall work to fill the schedule, while storm damaged regions see prices spike for a year or more after a major hail event.
DIY Versus Hiring a Roofing Crew
Roofing is the rare project where this guide sides firmly with the pros for the full job. The material savings of DIY are real, roughly 40 percent of the quote, but the work happens at height, moves tons of material, and a single flashing mistake can cause thousands in water damage that no one sees for a year. Manufacturer warranties on better shingles also commonly require certified installation for full coverage. Confident homeowners do save legitimately at the edges of the job: handling tear off and disposal under a contractor's install contract, replacing their own gutters afterward, or roofing a detached garage or shed as a learning project, where a mistake is cheap and the fall is shorter. For the main roof over your living space, get three written quotes with identical scope, and spend your energy there.
Size Your Roof Before You Collect Quotes
Roofers think in squares, and you should too. Our Roofing Calculator takes your roof's footprint, pitch and overhang and returns the surface area in squares, the shingle bundles required, and underlayment rolls. Measure the ground footprint of the house, add the eave overhangs, and pick the pitch closest to yours: the calculator applies the slope multiplier for you. Walk into quote season knowing whether you own a 17 square roof or a 24 square roof, and every conversation gets shorter and more honest. Pair that number with the per square ranges in the table above and you have a budget you can defend, plus a fast way to spot the quote that forgot the tear off.
Insurance, Storm Damage and Timing
One pricing situation deserves its own warning: the knock on the door after a storm. Hail and wind events bring traveling storm crews and, alongside legitimate roofers, a wave of too good quotes, pressure to sign an assignment of benefits, and promises that insurance will cover everything. Sometimes insurance does pay for storm damage, minus your deductible, and a local roofer can document damage for a claim honestly. What should never happen is a contract signed before your insurer inspects, or a roofer offering to absorb or rebate your deductible, which is insurance fraud in most states and a bright red flag about everything else in the paperwork. Get your quotes from established local companies with a physical address, verify the license and insurance certificates directly, and let the claim process run its course. As for timing outside emergencies: late fall in cold climates and the weeks after the spring rush in warm ones are when schedules open and prices soften. A roof that can wait a season for a better crew at a fair price usually should, because the crew, even more than the shingle, is what you are buying for the next 25 years.
Warranties: Read the Two Different Promises
Every roof quote waves a warranty, and there are actually two hiding in the word. The manufacturer warranty covers the shingles themselves against defects, often marketed as limited lifetime, prorated after an initial period, and usually voidable for poor attic ventilation or improper installation. The workmanship warranty is the roofer's own promise on installation, commonly 5 to 10 years from established local companies, and it is the one that matters for the leaks that actually happen, at flashings and penetrations. Ask for both in writing, ask what the transfer terms are if you sell the house, and be aware that the longest sounding number in the brochure is rarely the coverage you will use. A 10 year workmanship warranty from a company that has been on the same street for twenty years is worth more than a lifetime headline from a firm founded last spring.
