You generally can’t claim a new roof on your taxes as a one-time deduction. If the roof is on your primary home, the cost is added to your adjusted cost basis and pays off later by reducing the taxable gain when you sell. If the roof is on a rental property or commercial building, you recover the cost gradually through depreciation, and commercial owners have an option to deduct it all at once under Section 179. The two federal energy credits that used to reward energy-efficient and solar roofing expired for property placed in service after December 31, 2025.
Why a New Roof Isn’t a One-Year Write-Off
The IRS treats spending on property as either a repair or a capital improvement. Patching a leak or swapping out a few damaged shingles is a repair. Tearing off the old roof and installing a new one is a capital improvement, because you’re replacing a major structural component of the building. The tangible property regulations require that kind of replacement to be capitalized rather than expensed.1Internal Revenue Service. Tangible Property Regulations – Frequently Asked Questions
Capitalized means the cost gets recovered over time. How that recovery works depends entirely on what kind of property the roof covers.
New Roof on Your Primary Home
A new roof on the house you live in is a personal capital expenditure. The IRS doesn’t allow deductions for personal living expenses, so nothing about the roof shows up on your annual return. What it does is raise your adjusted basis in the home.
Your adjusted basis starts with the purchase price, adds every capital improvement you make over the years, and subtracts certain items like casualty losses.2Internal Revenue Service. Property (Basis, Sale of Home, etc.) 3 A $25,000 roof on top of a $300,000 purchase price gives you a $325,000 basis. When you sell, your gain is calculated against that higher number, so you owe less tax.
Most homeowners never feel this benefit. Under Section 121, a single filer can exclude up to $250,000 in gain on the sale of a primary residence, and married couples filing jointly can exclude up to $500,000, provided the ownership and use tests are met.3Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence If your gain falls under that ceiling, a higher basis changes nothing. The basis bump matters when you’ve owned the home a long time in an appreciating market, when you’re single with a big gain, or when the home was previously used as a rental.
Keep the Paperwork
Because the deduction happens years or decades later, records matter. Hold onto the contractor invoice, proof of payment, permit documents, and photos if you have them. The IRS expects you to keep these until at least three years after the return for the year you sell.4Internal Revenue Service. Publication 523 – Selling Your Home Store them digitally so they don’t get lost between now and then.
A Home Office Changes the Math Slightly
If you use part of your home regularly and exclusively for business, a portion of the roof becomes deductible through depreciation. Under the actual expense method, you multiply the roof’s cost by your business-use percentage and depreciate that amount over 39 years using the straight-line method.5Internal Revenue Service. Publication 587 – Business Use of Your Home A 10% home office and a $25,000 roof produces a $2,500 depreciable amount and roughly $64 per year in deductions.
The tradeoff: when you sell, the depreciation you claimed on the business portion can’t be sheltered by the Section 121 exclusion. It gets recaptured as taxable income. For most home-office users the arrangement still works out, because deductions arrive each year while recapture hits only at sale.
New Roof on a Rental Property
For a residential rental, the cost of the new roof is capitalized and depreciated using the straight-line method over 27.5 years under MACRS.6Internal Revenue Service. Publication 946 – How To Depreciate Property A $27,500 roof gives you roughly $1,000 in annual deductions against rental income. You report the depreciation on Form 4562, and it flows through to your Schedule E.
Bonus depreciation doesn’t help here. It generally applies to property with a recovery period of 20 years or less, and residential rental roofs sit at 27.5 years.7Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One Big Beautiful Bill Section 179 doesn’t help either: it’s reserved for nonresidential real property.
Don’t Forget to Write Off the Old Roof
When you replace a roof on a rental, the old roof still has undepreciated basis sitting on your books. Treasury Regulation 1.168(i)-8 lets you make a partial disposition election and recognize a loss for whatever basis remains on the roof you just removed.8Internal Revenue Service. Examining a Taxpayer Electing a Partial Disposition of a Building
Say you bought a rental for $200,000, and $15,000 of that was allocable to the roof. After 10 years of straight-line depreciation, roughly $9,455 has been deducted, leaving about $5,545 in remaining basis. The partial disposition election lets you claim that $5,545 as a loss in the year of the replacement, while you start fresh depreciation on the new roof. Without the election, you keep depreciating a roof that’s no longer on the building.
The election has to be made on a timely filed return, extensions included, for the year of the disposition. You’ll need a reasonable figure for the old roof’s original cost, which sometimes requires an estimate if it wasn’t broken out when you bought the property.
New Roof on Commercial Property
For nonresidential property, the default recovery period is 39 years of straight-line depreciation. But commercial owners have a shortcut. Section 179 allows an immediate deduction for the full cost of a new roof on nonresidential real property, up to the annual limit. For 2026 that limit is approximately $2,560,000, with a phase-out that begins when total qualifying property placed in service exceeds roughly $4,090,000.6Internal Revenue Service. Publication 946 – How To Depreciate Property
Publication 946 lists roofs among the improvements to nonresidential real property that qualify for Section 179.6Internal Revenue Service. Publication 946 – How To Depreciate Property The benefit is limited to commercial buildings, office space, retail, warehouses, and similar structures. A residential rental roof does not qualify, even if you treat the rental as a business.
Depreciation Comes Back at Sale
Every depreciation deduction you take on a rental or commercial roof has a tail. When you sell, the IRS recaptures the depreciation as unrecaptured Section 1250 gain, taxed at a maximum rate of 25%.9Internal Revenue Service. Treasury Decision 8836 – Section 1(h) Capital Gains Rate If you deducted $10,000 of the roof’s cost over the years, that $10,000 is carved out of your total gain and taxed at up to 25% on the sale.
For most owners the trade is still favorable, because deductions during ownership offset income at ordinary rates (often higher than 25%), and the time value of money works in your favor. But it’s a real number, and worth accounting for before you sell.
When a Storm Takes the Roof
If your roof is destroyed by a sudden event like a storm or fire, the replacement cost can sometimes be partially deductible as a casualty loss. The rules split by property type.
On a personal residence, since 2018 the casualty loss deduction is available only if the damage results from a federally declared disaster.10Internal Revenue Service. Topic No. 515 – Casualty, Disaster, and Theft Losses A hailstorm that damages your roof but doesn’t trigger a presidential declaration produces no deduction, no matter how large the bill. When the disaster rule is met, you calculate the loss as the smaller of the drop in fair market value or your adjusted basis, subtract insurance proceeds, subtract $100 per event, and then subtract 10% of your adjusted gross income.11Internal Revenue Service. Publication 547 – Casualties, Disasters, and Thefts
Insurance also affects your basis. If insurance covers $15,000 of a $25,000 replacement on your home, only the $10,000 you paid out of pocket increases your adjusted basis.2Internal Revenue Service. Property (Basis, Sale of Home, etc.) 3 If you had coverage and didn’t file a claim, the IRS treats the covered portion as recoverable and won’t let you deduct it.
For rental and business property, casualty losses aren’t limited to federally declared disasters. Landlords and business owners can generally deduct uninsured casualty losses in the year of the event.
The Energy Credits Are Gone for 2026
Through the end of 2025, two federal credits could offset part of a residential roof. Both terminated for property placed in service after December 31, 2025. If your roof went in before that date, you can still claim the credit on the return for the year of installation.
The Energy Efficient Home Improvement Credit under Section 25C covered 30% of the cost of qualifying energy-efficient roofing materials, specifically Energy Star-certified metal roofs and asphalt shingles with pigmented coatings or cooling granules. The credit was capped at $1,200 per year and claimed on Form 5695, with labor included in the 30% calculation.12Internal Revenue Service. Energy Efficient Home Improvement Credit The credit does not apply to roofs installed in 2026 or later.13Office of the Law Revision Counsel. 26 USC 25C – Energy Efficient Home Improvement Credit
The Residential Clean Energy Credit under Section 25D covered 30% of the cost of solar shingles or solar roofing tiles that generate electricity, with no dollar cap. Only roofing elements that themselves produce electricity qualified; conventional roofing beneath solar panels did not.14Internal Revenue Service. Residential Clean Energy Credit This credit also terminated for expenditures made after December 31, 2025.15Office of the Law Revision Counsel. 26 USC 25D – Residential Clean Energy Credit If you’re installing solar roofing in 2026, check whether your state offers its own credit or rebate.
