No Delaware statute licenses roofing as a trade — Title 24 has no roofing or home improvement contractor chapter. A roofer is a 'contractor' under 30 Del. C. § 2501 because the work alters and repairs buildings, so the state requirement is the Division of Revenue contractor license: $75 per year, a workers' compensation certificate, and a Department of Labor certificate of notice, plus a 0.6472% gross receipts license fee after a $100,000 monthly deduction.
Out-of-state roofers must file a surety bond of 6% of any contract (or yearly aggregate) of $20,000 or more before starting work (30 Del. C. § 375). Roofs, gutters, downspouts, and siding are named in Delaware's home improvement fraud statute, 11 Del. C. § 916, which reaches a class B felony for large losses. Re-roof permits and inspections are county or municipal.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Delaware's contractor license is a state Division of Revenue license; it does not test competency and does not replace local requirements. The Division of Revenue says your city and/or county may also require its own business license, and building permits and inspections come from New Castle, Kent, or Sussex County or the municipality where the work is. Electrical work is inspected statewide by Board-licensed third-party inspection agencies (24 Del. C. § 1420), and counties and municipalities may adopt plumbing, HVACR, and fuel gas codes that do not conflict with state licensing law (24 Del. C. § 1832).

Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Delaware's contractor license comes from the Division of Revenue: a fee, workers' comp proof, and gross receipts filings — no exam and no experience requirement.
11 Del. C. § 916 expressly covers roofs, siding, driveways, sidewalks, pools, painting, and more; penalties climb from a misdemeanor to a class B felony with the homeowner's loss.
Electrical work needs a DPR electrician license; plumbing and gas piping need a master plumber; HVACR needs a master HVACR license. The contractor license covers none of them.
