1 · Product approvals

Product approvals

Utah has no statewide roofing product approval system. Inspectors rely on the code's labeling rules and evaluation reports such as ICC-ES.

Code evaluation reports (ICC-ES, UL, IAPMO): 48 roofing reports

2 · Permit forms

City re-roof permits

The State Construction Code applies statewide, but permits are issued by each city or county building department. Utah's statewide permit-exemption amendments don't mention re-roofing, so check with the local building department.

Lien and contract rules

Utah liens run through the State Construction Registry: file a preliminary notice within 20 days of starting work, record the lien within 180 days of final completion (90 days after a notice of completion), and sue within 180 days of recording.

Preliminary notice within 20 days (Utah Code 38-1a-501)File a preliminary notice with the State Construction Registry within 20 days after you start work. A late notice only covers work done from 5 days after filing, and skipping it bars your lien.Record the lien (Utah Code 38-1a-502)Record the notice of construction lien with the county recorder within 180 days after final completion, or within 90 days after a notice of completion is filed (but no later than 180 days after completion). Mail the owner a copy within 30 days.Sue within 180 days (Utah Code 38-1a-701)File suit to enforce within 180 days after recording the lien and record a notice of pendency in the same window, or the lien is void. On a residence, you must also send the owner the required instructions and form.Statutory lien waivers (Utah Code 38-1a-802)Lien rights can only be waived for payment, using the statutory progress, final or restrictive check-endorsement forms, signed by the claimant. If the payment check doesn't clear, the waiver is void.Owner-occupied homes paid in full (Utah Code 38-11-107)Subs and suppliers can't keep a lien on an owner-occupied home if the owner had a written contract with a licensed or exempt contractor and paid it in full, or on any job with a general contract of $5,000 or less.
