Do you need a license to roof in Delaware?
No roofing trade license exists at the state level. All contractors must hold a Delaware Contractor Registration (a general business-compliance registration, not a trade license) plus a state business license from the Division of Revenue. New Castle County separately requires roofing contractors to obtain a county contractor license through its Department of Land Use; Kent and Sussex Counties run their own local permit and registration processes.
Who issues it: Delaware Department of Labor — Office of Contractor Registration (Division of Industrial Affairs).

Every figure here is a plain-English starting point read from the official state board — always confirm the current requirements at the source before you rely on them.
License type / class
No roofing trade license exists at the state level. All contractors must hold a Delaware Contractor Registration (a general business-compliance registration, not a trade license) plus a state business license from the Division of Revenue.

Issuing board
Delaware Department of Labor — Office of Contractor Registration (Division of Industrial Affairs) — onestop.delaware.gov/Operate_Contractors
Exam required
No
Experience / qualification
No state-mandated years-of-experience showing or trade exam applies to the Contractor Registration; its requirements are administrative — a Delaware business license, Delaware workers' compensation coverage, and an OSHA-compliant safety plan (or evidence one is being created). Check the roofing contractor license of the county you work in (New Castle in particular) for any additional local experience or testing requirements.
Bond
No bond is required for standard state Contractor Registration. (The Department of Labor may require a surety bond of a contractor that is the subject of an investigation or enforcement action under the registration law.)
Insurance minimum
Delaware workers' compensation insurance coverage is required to register (all employers must secure it before hiring/working in the state). General liability insurance isn't mandated at the state registration level but is commonly required by counties, general contractors, or clients.
Application fee
$200 for a one-year Private Construction registration, $300 if you'll bid on public/state contracts, or $500 to cover both. A two-year registration is available for $300 (private) or $500 (public), once you qualify with two consecutive years of continuous registration, timely renewal, and no prior labor-law violations. All fees are non-refundable.
Renewal
Renewals are accepted only within 90 days of your certificate's expiration date, through the Delaware One Stop portal.
Reciprocity
None found — Delaware's Contractor Registration applies the same way to in-state and out-of-state businesses working in Delaware; there's no reciprocity that exempts an out-of-state roofing license holder from registering.

Working without a license in Delaware
Operating without registering is subject to civil penalties under 19 Del.
