What Goes Into a Roof Replacement
A roof replacement is one of the largest home improvement projects a homeowner can undertake. The crew starts by tearing off the old shingles and underlayment, which involves a dumpster and a magnetic roller to pick up nails. They inspect the sheathing, which is the plywood or OSB layer under the shingles, and replace any rotted or damaged sections. They install new drip edge, ice and water shield along the eaves and in the valleys, synthetic underlayment across the rest of the roof, new flashing around chimneys and vents, and finally the new shingles, panels, or tiles. The job is loud, messy, and takes 1 to 5 days depending on the size and complexity of the roof.
2026 Price Ranges by Material
Asphalt shingles are the most common roofing material in the United States. Three tab shingles cost 4 to 6 dollars per square foot installed, while architectural shingles cost 5 to 8 dollars per square foot installed. Metal roofing is the next step up at 8 to 16 dollars per square foot installed for standing seam and 6 to 10 dollars per square foot for metal shingles. Wood shake costs 8 to 14 dollars per square foot installed and lasts 25 to 40 years. Clay tile costs 12 to 25 dollars per square foot installed and lasts 50 to 100 years. Concrete tile costs 10 to 20 dollars per square foot installed. Slate is the most expensive at 15 to 30 dollars per square foot installed and can last 75 to 200 years.
How Roof Size and Pitch Affect Price
Roofing is priced per square, which is 100 square feet of roof surface. A 2,000 square foot home with a simple gable roof has roughly 2,200 to 2,400 square feet of roof area, or 22 to 24 squares. A complex roof with multiple dormers, valleys, and hips can have 30 to 50 percent more roof area than the home footprint, which means a 2,000 square foot home with a complex roof has 28 to 32 squares. Roof pitch also matters, since a steep pitch requires more safety equipment, slower work, and sometimes special harnesses that add 5 to 15 percent to the labor. A two story home costs 5 to 10 percent more than a single story home with the same roof area because of the additional setup time.
Tear Off vs Overlay
A tear off removes the old shingles down to the sheathing, which lets the crew inspect the wood and install new underlayment. An overlay installs the new shingles on top of the old shingles, which is faster and cheaper but is not allowed by most building codes after one overlay. A tear off is the right choice if the old shingles are curling, missing, or have visible damage. An overlay is a temporary solution that adds 5 to 7 years of life to a roof that is at the end of its lifespan. Most roofing contractors recommend a tear off because the underlying sheathing, flashing, and ventilation can be inspected and upgraded.
What Affects the Final Bill
Several variables can push the price above the standard range. Steep pitches and complex rooflines add 10 to 25 percent. Multiple stories add 5 to 10 percent. New sheathing for rotted wood costs 2 to 5 dollars per square foot. New flashing for chimneys, vents, and skylights costs 300 to 800 dollars per penetration. Skylight replacement at the same time as the roof is much cheaper than doing it later, and adds 800 to 1,800 dollars per skylight. Gutter replacement at the same time as the roof is also cheaper than doing it later, and costs 6 to 12 dollars per linear foot. Permit fees vary by municipality but are usually 100 to 500 dollars.
How to Pick a Roofing Contractor
Get at least three written quotes from local contractors with a physical address and a real storefront. Confirm the contractor carries general liability insurance, workers compensation, and is licensed in your state. Check reviews on Google, the Better Business Bureau, and Nextdoor. Ask for references from the last 6 to 12 months and follow up. Confirm the crew is in house rather than subcontracted, since subcontracted work is the most common source of warranty disputes. Ask whether the quote includes tear off, disposal, new flashing, new underlayment, and permits. Finally, ask for a copy of the manufacturer warranty and the workmanship warranty, and confirm both are transferable if you sell the home.
Insurance and Financing
Homeowners insurance covers a roof replacement if the damage is from a covered peril such as hail, wind, fire, or falling tree. In hail prone states, the insurance company will send an adjuster to inspect the roof and may pay for the full replacement minus the deductible, which is usually 1,000 to 2,500 dollars. If insurance does not cover the replacement, many contractors offer 0 percent APR financing for 12 to 60 months through Synchrony, Service Finance, or GreenSky. The federal residential energy efficiency tax credit covers 30 percent of the cost of qualifying metal or asphalt shingles with a cool roof rating, up to 1,500 dollars per year. State and utility rebates for cool roofs and insulation are also available in many regions.
How to Extend the Life of a New Roof
A new roof should last 20 to 50 years depending on the material. The biggest factors in lifespan are the installation quality, the ventilation, and the maintenance. Make sure the attic has balanced intake and exhaust ventilation, since a hot attic cooks the shingles from below and shortens their life by 30 to 50 percent. Keep the gutters clean so water does not back up under the shingles. Trim overhanging tree branches so they do not scrape the shingles during wind storms. Have the roof inspected every 2 to 3 years and after any major storm. Address small repairs such as a lifted shingle or a cracked flashing immediately, before water damage spreads to the sheathing and the interior of the home.
