Delaware Roofing License Requirements (2026) | DE Revenue + Municipal Guide

Delaware does not issue a trade-specific roofing license. Every contractor working in Delaware — including roofers — must obtain a business license from the Delaware Division of Revenue under 30 Del. C. §2501 and pay the contractor gross receipts tax (currently 0.6842% after a monthly exclusion). There is no state exam. New Castle, Kent, and Sussex counties and incorporated cities layer additional building permit requirements, and Wilmington requires a separate city business license. Delaware is effectively a tax-registration plus insurance regime for roofers.

Regulatory Body Profile

Delaware Division of Professional Regulation (DPR) is the statutory authority responsible for issuing and enforcing this license under Delaware Code Title 24 (Professions and Occupations); Title 30 (Business License, Division of Revenue). The Delaware Division of Professional Regulation administers the trade licensing boards for electricians, plumbers, HVACR, and master pipefitters. Delaware does not issue a state general contractor license — any person doing contracting work in Delaware must instead hold a Delaware Business License from the Division of Revenue.

The Eligibility Audit

Eligibility begins with two baseline checks: the applicant must be 18 or older and must provide a valid Social Security Number or Individual Taxpayer Identification Number (ITIN). No Delaware residency requirement. Non-resident contractors must post a non-resident bond under 30 Del. C. §375.

Good moral character

Division of Revenue does not review character; municipal permits may.

Background investigation

No state background check for the business license.

Experience and Education Standards

Rather than a set number of years, the cited materials define eligibility through no state experience requirement — Delaware is a tax-registration state for contractors.

Education substitution

Not applicable.

The Exam Syllabus

The cited sources impose no written trade exam at the state level here. The path to the credential runs through: None — Delaware has no state roofing trade exam.

Bonding, Insurance & Financial Security

Where Applications Stall

The errors below are the ones that most frequently cost Delaware Roofing applicants time, drawn from the cited board guidance.

Missing gross receipts tax filings

The Division of Revenue aggressively pursues unfiled contractor gross receipts. Penalties plus interest accrue monthly.

Skipping the non-resident bond

Out-of-state roofers without the §375 bond cannot legally collect payment from Delaware owners. Owners can refuse to pay and Revenue will back them.

Forgetting Wilmington city license

Working inside Wilmington requires a separate city business license in addition to the state. Stop-work orders follow city enforcement sweeps.

Coastal wind nailing pattern

Sussex County adopts IBC high-wind fastening on Atlantic-facing properties. Six-nail patterns on shingles are enforced during hurricane season inspections.

OSHA fall protection

Federal OSHA 29 CFR 1926.501 applies. Delaware fall injuries on steep residential roofs rank among the top contractor claims.
