Is a New Roof Tax Deductible? 2026 Rules for Homeowners, Landlords, and Energy Upgrades

The answer to is a new roof tax deductible (for the full data set, see our the 2026 State of Roofing Insurance report) depends entirely on what kind of property the roof is on. On a primary residence, a new roof is not currently deductible but is a capital improvement that adds to your cost basis, reducing capital gains tax when you eventually sell. On a rental property, a new roof is depreciable over 27.5 years as a residential structural component. On a home office or business property, partial depreciation may apply. On any property, an energy-efficient roof may qualify for a Section 25C credit of up to $1,200 per year, and a roof-integrated solar system qualifies for the Section 25D federal residential clean energy credit at 30% through 2032. The rules in 2026 are roughly the same as 2025 with one important wrinkle on Section 25C documentation that the IRS tightened mid-2025.

Primary residence: not deductible, but it matters for cost basis

For your main home, the IRS classifies a new roof as a capital improvement, which means it is not deductible in the year you pay for it. The cost goes into your home’s tax basis. When you sell the home, your taxable gain is sale price minus selling expenses minus adjusted cost basis. A higher cost basis means a lower taxable gain.

Here is the math. You bought your house in 2010 for $300,000. You put a new roof on in 2026 for $18,000. You sell in 2032 for $580,000. Without the roof, your gain is $580,000 minus $300,000 equals $280,000. With the roof added to cost basis, your gain is $580,000 minus $318,000 equals $262,000. The $18,000 roof reduced your gain by $18,000.

For most homeowners selling a primary residence, the Section 121 exclusion ($250,000 for single filers, $500,000 for joint) wipes out the gain entirely. In that case the capital improvement basis bump has no immediate tax effect. But for homes in high-cost markets, owners with multiple properties, or sellers whose gain exceeds the exclusion, every dollar of cost basis is a dollar of taxable gain avoided at the long-term capital gains rate (0%, 15%, or 20% federal depending on income, plus state tax).

Keep the receipts forever

The IRS does not require you to attach roof receipts to your annual return. They do require you to have them when you sell. The records you need to keep until the year after you sell the home (plus any audit window):

• Contractor invoice with itemized scope
• Proof of payment (canceled checks, credit card statements, bank transfers)
• Permit copies
• Manufacturer warranty registration
• Photos showing the work was performed

Lose the receipts and the basis bump disappears. For a primary residence inhabited 20+ years, that can be a $30,000 to $80,000 paper trail you need to maintain.

Rental property: full depreciation over 27.5 years

If the property is a residential rental (single family rental, duplex, triplex, fourplex, or any unit you rent out), the roof is a structural component depreciated as part of the building over 27.5 years under the Modified Accelerated Cost Recovery System (MACRS). You file Form 4562 in the year you place the roof in service and the depreciation flows to Schedule E on your personal return (or Form 8825 for partnerships).

Annual depreciation on a $20,000 roof on a residential rental: $20,000 divided by 27.5 equals $727 per year of depreciation expense, every year for 27.5 years. That expense reduces rental income, which reduces taxable income. At a 24% marginal federal bracket plus 5% state, that is $211 per year of tax savings, totaling roughly $5,800 over the 27.5-year recovery period.

Commercial or mixed-use property

If the rental is commercial (office, retail, industrial) or non-residential mixed-use, the recovery period extends to 39 years instead of 27.5. The annual depreciation drops accordingly. A $20,000 roof on a commercial property depreciates at $513 per year over 39 years.

The 2018 change that allowed Section 179 on commercial roofs

The Tax Cuts and Jobs Act of 2017 (effective tax years beginning after 2017) added roofs to the list of property eligible for Section 179 expensing on non-residential commercial buildings. This means a commercial building owner can elect to expense the entire roof in the year placed in service, up to the Section 179 cap ($1.22 million for 2025, indexed for 2026). Residential rental roofs are not Section 179 eligible. The commercial-roof election can be a six-figure timing benefit for landlords with multiple commercial buildings.

Home office: partial deduction

If you have a qualified home office that you use exclusively and regularly for business, you can depreciate the business-use portion of the roof over 39 years (the commercial recovery period applies to the business portion even of a residential home).

The math: home office is 240 square feet, total home is 2,000 square feet. Business use percentage is 12%. The $18,000 roof has $2,160 attributable to the business portion ($18,000 times 12%). That $2,160 depreciates over 39 years at $55 per year of business deduction on Form 8829 attached to Schedule C.

The catch: when you sell the home, the depreciation taken on the business portion is recaptured at ordinary rates up to 25%, even if Section 121 would otherwise exclude the gain. For most home-office filers, the recapture exposure is small enough that taking the deduction still nets positive. For high earners with large home offices and big anticipated home appreciation, the math gets closer to neutral.

For homeowners using the simplified home office deduction ($5 per square foot, max $1,500), you do not separately depreciate the roof. The simplified method already includes a notional depreciation component.

Section 25C: energy efficient home improvement credit

The Inflation Reduction Act expanded and renamed Section 25C as the Energy Efficient Home Improvement Credit, effective for property placed in service after 2022 and continuing through 2032. The credit covers 30% of qualifying improvement costs up to annual caps.

How roofs fit into 25C

Pure roofing materials (asphalt shingles, metal panels, underlayment, drip edge, flashing) are not covered by Section 25C. The credit covers specific energy-property categories: insulation, exterior doors, windows and skylights, heat pumps, central AC, biomass stoves, and home energy audits. A standard roof replacement does not qualify.

What does qualify under 25C in connection with a roof project:

• Attic insulation upgrades performed during the reroof. Caps at 30% of cost, $1,200 annual.
• Roof-mounted skylight upgrades to ENERGY STAR-certified models. Caps at $600 annually under the windows/skylights category.
• Roof-mounted attic ventilation fans, only if part of an ENERGY STAR-certified attic ventilation system. Very narrow path.

For full attic ventilation specifics, see attic ventilation. The intersection of attic insulation upgrades and a reroof is the easiest 25C win because the roof deck access makes the insulation work cheaper.

Cool roofs and Section 25C: the persistent myth

An older version of Section 25C (pre-2022) included a category for ENERGY STAR-rated metal and asphalt roofs with appropriate pigmented coatings or cooling granules. That provision was sunset and is no longer in the current 25C statute. As of 2026, cool roofs themselves are not Section 25C eligible. Salespeople still claim otherwise. They are wrong.

Section 25D: residential clean energy credit and solar roofs

Section 25D is the federal credit for residential clean energy property, currently set at 30% through 2032, then stepping down to 26% in 2033 and 22% in 2034 before expiring. The credit covers solar electric (PV), solar water heating, fuel cells, geothermal heat pumps, small wind, and battery storage.

A solar PV system installed on a roof qualifies for 30% of installed cost with no annual cap. Integrated solar roofing products such as the Tesla Solar Roof and GAF Energy Timberline Solar shingles also qualify, but with an important nuance: only the portion of the cost attributable to solar electric generation qualifies, not the underlying roof.

The Tesla Solar Roof and GAF Energy allocation

Tesla’s Solar Roof is sold as an integrated product that replaces the entire roof with a combination of active solar tiles and inert glass tiles. The IRS guidance treats the active tiles plus inverter, wiring, and racking as Section 25D property. The inert tiles are treated as regular roofing material and do not qualify for the credit (but do add to cost basis as a capital improvement).

Tesla itemizes the proposal accordingly. The 30% credit applies to the active solar portion. The inert portion is treated as roofing. The customer who installs a $80,000 Tesla Solar Roof might see $35,000 attributable to active solar and $45,000 to inert tiles. The credit is then 30% of $35,000 equals $10,500. The $45,000 goes into home cost basis.

GAF Energy’s Timberline Solar product works similarly: integrated solar shingles installed alongside standard Timberline shingles. The active solar portion qualifies for Section 25D. The non-active shingles are regular roofing.

Conventional rack-mounted PV systems

A conventional PV system racked on top of an existing roof is fully Section 25D eligible. The credit covers panels, inverters, racking, wiring, labor, permits, and interconnection. If the roof itself needs replacement to support the new PV, only the active solar costs qualify for the credit; the roof replacement is a capital improvement on the primary residence (basis bump only) or depreciable on a rental.

For homeowners weighing a roof replacement before going solar, the timing matters: do the roof first, then add solar, and keep the costs cleanly separated on invoices so the Section 25D credit calculation is clean.

Casualty loss deduction: narrow window

If a hurricane, hailstorm, tornado, or wildfire destroys or damages your roof and you live in a federally declared disaster zone, you may qualify for a casualty loss deduction. The Tax Cuts and Jobs Act limited this deduction to federally declared disasters for tax years 2018 through 2025, and it was extended through 2028 in subsequent legislation.

How the casualty loss math works

The deduction equals the decline in fair market value caused by the disaster, minus any insurance recovery, minus $100, minus 10% of adjusted gross income. The result is what you can deduct as an itemized deduction.

Example: 2026 hurricane in a federally declared disaster zone destroys $30,000 of roof value. Insurance pays $22,000 RCV. Unreimbursed loss is $8,000. Subtract $100, getting $7,900. Your AGI is $120,000, so 10% is $12,000. Since $7,900 is less than $12,000, no deduction. The casualty loss deduction only helps when uncovered losses are large relative to income.

For most homeowners with adequate insurance, casualty loss is irrelevant. For uninsured or underinsured losses, particularly on ACV policies with large depreciation gaps, the casualty loss deduction can recover meaningful dollars. See our guide on actual cash value roof for how ACV creates uncovered losses.

Repairs vs improvements: the tax distinction

The IRS distinguishes between repairs (currently deductible on rentals, not deductible on personal residences) and improvements (capitalized and depreciated or basis-added). The distinction matters mainly for rental owners trying to expense costs faster.

What counts as a repair

• Replacing a few missing or damaged shingles after wind
• Patching a leak with a new flashing piece
• Re-sealing a pipe boot or vent collar
• Spot replacing damaged decking under a small repair

What counts as an improvement

• Full roof replacement
• Major slope reroof (more than 40% of total roof area)
• Upgrade from 3-tab to architectural or from architectural to metal
• Adding a structural component (new dormer, skylight, chimney chase)
• Replacing the entire deck

On a rental property, repair expenses go on Schedule E or Form 8825 in the year incurred and reduce that year’s income dollar for dollar. Improvements get capitalized and depreciated over 27.5 years. The De Minimis Safe Harbor election allows expensing of items under $2,500 per invoice, which can convert smaller capital items into current deductions.

Energy-efficient rebates: state and utility

Separate from federal credits, many states and utilities offer rebates for cool roofs, attic insulation upgrades, and reflective coatings. California Title 24 includes cool roof requirements with associated rebates. Texas utilities like Austin Energy and CenterPoint offer attic insulation rebates that pair well with reroof projects. Florida utilities like FPL and Duke Energy run periodic cool roof and attic ventilation rebate programs.

These rebates are not federal tax credits and follow state-specific application processes. The IRS treatment varies: federal-utility rebates that reduce your purchase price are subtracted from cost basis or depreciation basis, not separately deductible. State income tax rebates may be includible in federal income depending on the program structure.

What to ask your accountant in 2026

If you put a new roof on in 2025 or plan to in 2026, the questions to bring to your accountant:

• For a primary residence: did the project include any qualifying Section 25C work (insulation, skylights, ventilation) that should be claimed in the year of installation?
• For a primary residence with solar: how should the invoice be allocated between solar and roofing for Section 25D?
• For a rental: should the roof be depreciated over 27.5 years (residential) or 39 years (commercial), and is the building correctly classified?
• For a home office: what is the business-use percentage, and what is the depreciation recapture exposure if the home is sold within the next 10 years?
• For a casualty loss: was the loss in a federally declared disaster zone, and what are the documented FMV decline numbers before and after?

For a deeper look at total roof project costs that drive these basis and depreciation calculations, see how much does a new roof cost and metal roof cost.

FAQ

Can I deduct my new roof if I work from home full time?

Only the business-use percentage of the roof, depreciated over 39 years, and only if you qualify for the home office deduction (exclusive and regular use for business). The deduction is small and creates depreciation recapture exposure if you sell. Most home-based workers do not claim it because the savings are modest and the recordkeeping burden is real.

Does a metal roof qualify for any tax benefit a shingle roof does not?

Not at the federal level for primary residences. Section 25C no longer includes ENERGY STAR metal roofs in its current form. On rental properties both materials depreciate the same way over 27.5 years. State and utility programs occasionally favor reflective metal roofs, but those are rebates, not federal deductions.

I bought my house with a brand new roof. Does that count as a deductible expense?

No. The cost of the new roof was rolled into your purchase price and is already part of your cost basis. You cannot separately deduct it. You can deduct or depreciate only roof expenditures you make after you take ownership.

What if my insurance paid for the roof? Can I still take the basis adjustment?

Only the portion you paid out of pocket (deductible plus any unreimbursed costs) adds to cost basis. Amounts the insurance paid do not. On a casualty loss, the insurance proceeds first offset the loss, and only the unrecovered portion is potentially deductible.

Does Section 25D apply if I lease my solar system instead of buying?

No. The 30% Section 25D credit goes to the owner of the system. If you lease or sign a power purchase agreement (PPA), the solar company owns the system and claims the credit. They may pass some of the value into your monthly payment, but you do not claim it directly.

Bottom line

For a primary residence, a new roof is not deductible this year, but it permanently raises your cost basis and reduces capital gains tax when you sell. For a rental, depreciate the roof over 27.5 years (residential) or 39 years (commercial) and capture the annual deduction on Schedule E. For a solar roof, claim the 30% Section 25D credit on the active solar portion. For attic insulation, skylights, or ventilation upgrades done during the reroof, claim Section 25C up to $1,200 per year. Keep receipts and warranties forever. The capital gains math compounds across decades and lost paperwork is lost basis.
