Headline finding: A renter is roughly twice as likely to live under a failing roof as a homeowner, and among the lowest-income households the rate runs two to three times the national average. Deferred roof repair in America is not spread evenly. It concentrates on low-income renters and households of color, according to a Roofing Brief synthesis of the U.S. Census Bureau’s American Housing Survey (AHS) and the Harvard Joint Center for Housing Studies (JCHS).
This report quantifies the roof gap: who lives under leaking, holed, and sagging roofs in the United States, sorted by income, tenure (owner versus renter), and race. Every figure below cites a named primary source and year. Roof condition is one of the clearest physical markers of housing inequality, because a roof is expensive, its failure is visible, and its repair is easy to defer until water is already inside.
The roof gap in one number
About 6.45 million U.S. homes, roughly 5 percent of the occupied housing stock, were classified as inadequate in the 2023 American Housing Survey, and more of them were rented (3.5 million) than owned (2.8 million), per analysis of AHS 2023 by the National Association of Home Builders’ Eye on Housing (2025). Because renters are only about a third of all households, that split means a renter household carries a far higher risk of living in substandard housing than an owner household. Roof leaks, holes, and sagging are core inputs to that “inadequate” classification.
How many American roofs are actually failing?
Roughly 6 million U.S. homes reported a roof leak and about 1.5 million reported a hole in the roof in the 2023 American Housing Survey, per Roofing Contractor’s analysis of AHS data (2024). Roof leaks reached about 4.4 percent of households in 2023, down from 7.6 percent in 1973, according to HUD USER’s AHS review. The table below separates the specific roof and water-intrusion defects the AHS measures. These counts overlap and should not be summed.
| Roof or water-intrusion defect | U.S. homes affected | Source (year) |
|---|---|---|
| Water leakage from outside (roof, walls, windows) | ~11.4 million | AHS 2021, via HUD USER |
| Roof leaks | ~6.0 million (~4.4% of households) | AHS 2023, via Roofing Contractor / HUD USER |
| Missing roofing material | ~3.5 million | AHS 2023, via Roofing Contractor |
| Sagging roof | ~1.9 million | AHS 2023, via Roofing Contractor |
| Holes in the roof | ~1.5 million | AHS 2023, via Roofing Contractor |
Renters live under failing roofs at roughly twice the owner rate
Renters carry the heavier roof burden because the person who controls repairs (the landlord) is not the person who lives under the leak. Dividing the AHS 2023 inadequate-unit counts by tenure by each group’s household total gives an estimated 7 to 8 percent of renter households in inadequate housing versus roughly 3 percent of owner households, a Roofing Brief calculation using AHS 2023 counts (3.5 million renter and 2.8 million owner units) against Census 2023 tenure totals of about 45 million renter and 86 million owner households. That is a gap of roughly two to one, and it holds before income is even considered.
The Harvard JCHS finds the same direction inside income bands. Among the lowest income fifth, 10.6 percent of renters lived in inadequate housing in 2021, nearly double the 5.6 percent share among the highest-income renters, per JCHS analysis of AHS microdata. Substandard conditions, including persistent water leaks and holes in the roof, “disproportionately impact renters,” the JCHS notes.
Income decides who gets a new roof
Roof condition tracks income more sharply than almost any other housing defect, because a full roof replacement is one of the largest single repairs a household faces. The table below ranks inadequate-housing rates by tenure and income band, the closest published proxy for who lives under a failing roof.
| Household group | In inadequate housing | Source (year) |
|---|---|---|
| Renters, lowest income fifth | 10.6% | JCHS / AHS 2021 |
| Owners, lowest income fifth (under ~$24,000) | 7.0% | JCHS / AHS 2021 |
| Renters, highest income fifth | 5.6% | JCHS / AHS 2021 |
| All U.S. households | ~5.0% | AHS 2023, via Eye on Housing |
| Owners, highest income fifth (~$129,000+) | ~2.3% | JCHS / AHS 2021 |
A low-income owner is more than three times as likely to live in inadequate housing as a high-income owner (7.0 percent versus about 2.3 percent), per JCHS analysis of AHS 2021. The mechanism is spending. Among owners of homes built before 1960, the highest income fifth spent three times as much on improvements and repairs in 2023 as the lowest, per the JCHS 2025 review of AHS data.
The racial gap in roof condition
Housing disrepair, including roof and outside-structural problems, falls harder on households of color even at the same income level. Among households in the bottom third of incomes, 10.4 percent of Hispanic and 10.0 percent of Black households lived in inadequate housing in 2021, well above the 6.3 percent share for white households, per JCHS analysis of AHS microdata. The JCHS attributes the gap to neighborhoods “shaped by segregation and structural disinvestment,” where substandard housing compounds existing disparities in health and wealth.
| Bottom-third-income households | In inadequate housing (2021) |
|---|---|
| Hispanic householder | 10.4% |
| Black householder | 10.0% |
| White householder | 6.3% |

Where failing roofs cluster
Roof-leak rates cluster in older, wetter, and lower-income metros. California metros led on raw leak share, with Riverside at 6.6 percent of households, Los Angeles at 6.0 percent, and San Francisco at 5.7 percent, per Roofing Contractor’s AHS analysis (2024). On a composite score combining leaks, missing material, holes, and sagging, Detroit (14.2), Philadelphia (14.1), and Los Angeles (13.9) ranked worst, while Atlanta, Seattle, and Miami tied best at 7.1.
Housing age is a strong predictor. Homes built before 1940 had a 9 percent inadequacy rate versus 3 percent for homes built since 2000, per Eye on Housing’s AHS 2023 analysis. Older housing stock concentrates in the same disinvested neighborhoods where deferred roof repair is most common. For a metro-level view of roof age, see The Roofing Brief’s roof-age estimates.
Why low-income roofs stay broken: the deferred-repair trap
Low-income households do not defer roof repair by choice. They defer it because a roof replacement, often $8,000 to $25,000 depending on size and material, exceeds what a constrained household can absorb, so small leaks become structural failures. The AHS spending data shows the trap directly.
- Many spend nothing. In 2023, 28 percent of homeowners in the lowest income fifth spent nothing on home improvements or maintenance, double the 14 percent share among higher-income owners, per JCHS (2025).
- A 3-to-1 spending gap. On pre-1960 homes, the top income fifth outspent the bottom fifth three to one on repairs and improvements in 2023, per JCHS (2025).
- Repair, not upgrade. When lower-income owners do spend, 27 percent of their outlays went to routine maintenance in 2023 versus 16 percent for higher-income owners, per JCHS (2025), a sign they are patching, not replacing.
Older adults sit at the intersection of fixed incomes and aging homes. Among households aged 65 and older, 38.5 percent of low-income households reported disrepair versus 34.9 percent of moderate and high-income households, per a 2025 peer-reviewed analysis of AHS 2023 (Journal of the American Geriatrics Society, PMC).

Methodology
This report synthesizes published national figures from the U.S. Census Bureau’s American Housing Survey (2021 and 2023 waves), the Harvard Joint Center for Housing Studies’ analyses of AHS microdata, and peer-reviewed AHS-based research. Roof-defect counts come from Roofing Contractor’s and HUD USER’s tabulations of AHS items (roof leaks, holes, sagging, missing material, and water leakage from outside). Tenure, income, and race breakdowns come from JCHS and Eye on Housing analyses of AHS. The tenure inadequacy rate is a Roofing Brief calculation dividing AHS 2023 inadequate-unit counts by tenure against Census 2023 household totals; it is an estimate, not a published AHS rate. Where a comparison blends the 2021 and 2023 AHS waves, the year is labeled in the source column.
Limitations
Several caveats apply. The AHS “inadequate housing” measure is a composite that includes plumbing, heating, electrical, and structural items, not a roof-only metric, so the composite inadequacy rate and the roof-defect counts are distinct measures and cannot be summed. Roof leaks and holes are self-reported by occupants, not verified by roof inspection, and may understate slow or attic-contained leaks. Race breakdowns here are available only for the bottom third of incomes. Metro leak shares rest on smaller samples and carry wider sampling error. National counts are subject to AHS sampling error, and figures are rounded. Dollar ranges for roof replacement vary by region, pitch, material, and access.
What the roof gap means
The pattern is consistent across every cut of the data: roof failure follows income, tenure, and race, and it compounds over time because the households least able to afford a new roof are the ones deferring it. Closing the gap depends less on roofing technology than on financing and repair-assistance access. For how repair costs vary by geography, see The Roofing Brief’s roof replacement cost by metro and roofing affordability index.
