Warranty details.
Plain and simple.

One local team to help you find answers. Coverage comes from the manufacturer of the building you choose.

United Metal Buildings / Metal structures

Four kinds of coverage.

Summary of United’s published terms. Check the written warranty for your specific building.

1 YEAR FROM INSTALLATION

Maintenance

Specified leaks, repairs, frame rust, and wind damage to panels/trim. Horizontal panel-overlap leaks and base-rail leaks are excluded.

5 YEARS / 20 YEARS

Frame rust

14-gauge: five years. 12-gauge: twenty years. Proper care required; minor surface rust and misuse excluded.

20 YEARS

Frame wind damage

Up to 120 mph, subject to correct location-specific anchoring. Customer-supplied or improperly installed anchors are excluded.

30 DAYS FROM INSTALLATION

Doors & windows

Report defects within thirty days. Covers specified operation defects or visible installation damage; doors forced open by wind are excluded.

Care, changes & claims

Structural changes or added truss loads can void coverage. Chemical damage may affect eligibility. Keep your order number, photos, and issue details for United’s claim form. United states an initial review of 1–3 business days; approval and repair scheduling follow its assessment.

Warranty terms are not a site-specific engineering or building-code certification. Concrete and other separately quoted work require their own written scope and terms.

Cardinal / Portable buildings

The Cardinal Guarantee.

Cardinal publishes a ten-year guarantee for eligible purchases made on or after March 1, 2026, covering product failure, wind-related shifting, freeze/thaw settling, and storm damage.

Its guarantee excludes C+, Eco Sheds, animal structures, and pre-owned buildings. Ask for the terms for your model; eligible products and coverage differ.

Keep your coverage in good standing.

Use a properly prepared, level site, maintain the building, avoid structural modifications, and use Cardinal-approved movers.

Exclusions include outside work, drainage/condensation issues, heating or cooling systems, neglect, misuse, animals, and later site erosion. Confirm ownership and transferability in writing.

Cardinal separately lists a two-year warranty for C+ buildings. See its policy and request your building’s full terms.

The written terms govern.

This guide is a summary, not an additional warranty from Roberts. Ask for the current manufacturer warranty before ordering. Coverage depends on your building, purchase date, installation, care, and the applicable exclusions.
