Roofs are named expressly in the Home Improvement Act's definition (CGS § 20-419(5)), so re-roofing a house or residential building of up to six units requires a DCP Home Improvement Contractor registration: $120 plus a $100 guaranty-fund fee each year, at least $20,000 of general liability insurance, and a written contract that meets § 20-429.
On commercial buildings, the Major Contractor law (§ 20-341gg) names roofing as structural work, so roofers working on a structure over the § 29-276b threshold limits must register as major contractors. Commercial roofing on smaller buildings has no state registration — only the local building permit.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Re-roof permits and inspections are issued by each town or city building official (CGS § 29-263); Connecticut has no county layer. The HIC registration is statewide.
The local offices section below names the exact permit desk for every Connecticut county on file.
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.
The Home Improvement Act lists roofs among covered work; the job threshold is a total price over $200.
A person whose home-improvement contracts total $1,000 or less in any 12 months is not a 'contractor' under § 20-419(4)(B).
Roofing is named as structural work in § 20-341gg(a), so threshold buildings require Major Contractor registration.
A practical sequence for a new roofing contractor in Connecticut. Actual agency processing times are noted in the ledger above.
Each item names the issuing authority, cycle, and citation.
Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Offering to make or making a home improvement without a current certificate is a crime, and any violation of the Act is an unfair or deceptive trade practice under CUTPA.
After notice and hearing, DCP may fine anyone who works unregistered, works on an expired certificate, or violates the Act or its regulations.
A home improvement contract that is not in writing, signed, dated, and complete with the required terms is not valid or enforceable against the owner.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.

Pending verification: Initial Major Contractor application fee (set by DCP regulation under § 20-341gg(c); DCP's page lists only the $500 renewal fee) · Whether Bridgeport, Hartford, or New Haven imposes any separate local contractor registration (none appears in state law; municipal codes were not reviewed) · Whether any 2026 regular-session public act changed these fees, thresholds, or insurance minimums — the newest statutory text retrieved is the 2026 Supplement, which reflects only the 2025 session
