How long does a roof last?
Asphalt shingle roofs get a standard life of 20 years in the Family column of the U.S. Department of Housing and Urban Development (HUD) planning table, a figure for multifamily properties and not a measured life of a house's roof (structured on the ASTM E2018-08 outline, no issue date, read 2026-10-17, national, multifamily, n not published by the source).

Our own share, from the public microdata of the 2023 American Housing Survey (AHS), with the U.S. Census Bureau as the source of the original data: 9.6% of US owner-occupied homes had a job coded “Added or replaced roofing” in the two years before their 2023 interview (Census AHS 2023, read 2026-10-17, n = 28,192, SE 0.2 points). In the survey's definitions, roofing is meant “to capture the replacement of the entire roof or at least most of it”. The questionnaire reads “please do not include any part of the MAJOR disaster work already reported” before these questions, so that work is not in the share. The share is a rate of roofing jobs in that window, never how long a roof lasts.
In our own counts, n is the number of surveyed households behind a share and SE is its standard error, a measure of sampling error, in percentage points.
How long it lasts, by source
- HUD's sloped-roof rows, Family column: 20 years for “Asphalt Shingle”, 25 for “Wood Shingle, Cedar Shakes/Shingles”, 50 for “Metal”, 60 for “Clay/cementitious barrel tile” and 75 for “Slate shingle” (structured on the ASTM E2018-08 outline, no issue date, read 2026-10-17, national, multifamily, n not published by the source). Each is a standard planning life for multifamily capital needs assessments, not a measured life of one home's roof, so the five stay as HUD lists them by material rather than blended into one number.
Should you repair or replace a roof?
The AHS draws a line between the two for its own count: its roofing item “is meant to capture the replacement of the entire roof or at least most of it”, and “Anything less, such as the repair of a hole or leak, or the replacement of a small section, would be considered maintenance.” (AHS 2023 definitions, read 2026-10-17, national).
HUD's planning table fixes one standard life per component type, and for an existing component in a capital needs assessment the table's notes read “The user may estimate the Remaining Useful Life of any existing component independent of the Standard EUL”, EUL meaning estimated useful life (structured on the ASTM E2018-08 outline, no issue date, read 2026-10-17, national, multifamily).
Whether a repair or a new roof makes sense depends on which part failed, the roof's age and condition, and what written bids for each option say.

What a new roof costs is a separate question, answered with its own sources on our national cost page: How much does it cost to replace a roof?
