Are Roof Repairs Tax Deductible?

An improvement is different. Publication 530 defines it as work that materially adds to the value of your home, considerably prolongs its useful life or adapts it to new uses, and it names replacing an entire roof as an example. Improvements are not deducted either, but you add their cost to your home's basis, which reduces your taxable gain when you sell.

There is one bridge between the two: repairs done as part of an extensive remodeling or restoration of the home are treated as improvements. A deck repair done while the whole roof is being replaced is part of the replacement, not a separate repair.

For most Michigan homeowners, basis matters less than it used to. Under Publication 523, you can exclude up to $250,000 of gain on the sale of your main home, or $500,000 for a married couple filing jointly, if you owned it and lived in it for at least two of the five years before the sale. If your gain could exceed that, or the house might become a rental, keep every roof replacement invoice with your closing papers.

For rental and business property, the line between repair and improvement comes from the tangible property regulations at 26 CFR 1.263(a)-3. Work must be capitalized if it is a betterment (fixing a defect that existed when you bought the property, or a material addition or increase in capacity, strength or quality), a restoration (including replacing a major component or substantial structural part) or an adaptation to a new use. The roof is part of the building structure.

The regulations include roof examples. In one, an owner whose whole roof had rotted decking replaced the entire roof, including decking, insulation and roofing, and had to capitalize it as a restoration because the roof is a major component of the building. In another, an owner who stripped a worn rubber membrane and replaced it with a comparable one did not have to capitalize the cost, because the membrane alone was not a significant portion of the roof. Most targeted roof repairs look much more like the second example than the first.

The regulations also give three safe harbors that can let small landlords deduct costs that might otherwise be capitalized. Each has conditions and some require an annual election, so they belong in a conversation with your preparer.

If you qualify for the home office deduction because you use part of your home regularly and exclusively for a business, Publication 587 splits home expenses into direct costs (only for the office) and indirect costs (for keeping up and running the entire home). A roof repair benefits the whole house, so it is an indirect expense. The IRS's own example uses a furnace repair: if 10 percent of the home is used for business, you can deduct 10 percent of the cost.

That only works under the regular method, which uses actual expenses. If you use the simplified method, a flat $5 per square foot on up to 300 square feet, you cannot deduct actual home expenses such as a share of a roof repair. A full roof replacement made after you start using the office is an improvement and is depreciated by the business percentage rather than deducted at once.

Michigan's income tax begins from federal numbers. Under MCL 206.30, taxable income for an individual is adjusted gross income as defined in the Internal Revenue Code, with a list of Michigan additions and subtractions. Rental and business roof expenses you deduct federally reduce adjusted gross income, so they carry through to your Michigan return. We found no Michigan deduction or credit for repairs to a personal residence, so a homeowner's roof repair is not deductible on the state return either.

Energy credits will not help with a roof that goes on now. Publication 530 states that the energy efficient home improvement credit cannot be claimed for property placed in service after December 31, 2025, and the residential clean energy credit cannot be claimed for expenditures made after that date.

Two related Michigan questions have their own pages: how sales and use tax shows up in a repair price, and whether roof work changes your property tax assessment.
