Delaware Roofing Contractor Checklist: What to Verify Before You Hire

Your roof is one of the most expensive parts of your home to repair or replace. A bad hire can cost you tens of thousands of dollars and leave you with leaks, code violations, or no recourse when something goes wrong. This Delaware roofing contractor checklist walks you through every step — from license lookup to final walkthrough — so you can hire with confidence.

1. Verify the Contractor's Delaware License

Delaware requires home improvement contractors to register with the Delaware Division of Revenue and, in many cases, hold a Home Improvement Contractor (HIC) license issued through the Delaware Division of Professional Regulation (DPR). Roofing work typically falls under this umbrella.

Before you agree to anything:

• Ask for the contractor's HIC registration number.
• Verify it on the Delaware DPR public license search.
• Check whether the license is active and free of disciplinary actions.
• For work in specific counties or municipalities (like Wilmington), ask if any additional local permits or registrations apply.

Never hire an unlicensed contractor for roofing work in Delaware. If something goes wrong, you may have limited legal options.

2. Confirm Insurance Coverage

A legitimate roofing contractor in Delaware should carry two types of insurance — and you should verify both before work begins:

General Liability Insurance — covers property damage caused by the crew (broken windows, damage to siding, etc.).

Workers' Compensation Insurance — covers injuries to workers on your property. Without it, you could be held liable if a worker is hurt on your roof.

Ask the contractor to provide certificates of insurance (COIs) naming you as an additional insured. Call the insurance company directly to confirm the policy is active. Don't just accept a paper copy — policies can lapse.

3. Get a Detailed Written Contract

Under Delaware's Home Improvement Contractor Act (6 Del. C. § 2571 et seq.), contracts for home improvement work above a certain dollar threshold must be in writing and include specific terms. Even for smaller jobs, always insist on a written contract. It should include:

• Scope of work — exact materials, brand/type of shingles, underlayment, flashing details
• Start and estimated completion dates
• Total price and payment schedule
• Permit responsibility — who pulls the permit (should be the contractor, not you)
• Cleanup and debris removal
• Warranty terms — both the manufacturer's warranty on materials AND the contractor's labor warranty
• Change order process — how any additional costs are approved in writing

If a contractor pushes back on putting things in writing, that's a red flag. Talk to our 24/7 AI if you've already signed a contract you're unsure about.

4. Check References, Reviews, and History

A licensed and insured contractor can still do poor work. Do your homework:

• Ask for at least three local references and actually call them.
• Search the contractor's business name on the Better Business Bureau (BBB) website.
• Read Google and Yelp reviews, looking for patterns (not just one or two outliers).
• Search Delaware courts' public records portal to see if the contractor has a history of lawsuits or judgments filed by homeowners.
• Ask how long they've been operating in Delaware — local experience with regional weather (coastal storms, mid-Atlantic freeze-thaw cycles) matters.

5. Understand the Permit and Inspection Process

Most roofing replacements in Delaware require a building permit from your local county or municipal building department. Permits protect you — they trigger an official inspection to confirm the work meets Delaware's adopted building code.

• The contractor should pull the permit, not you. If they ask you to pull it, that's a warning sign.
• Ask the contractor when the inspection is scheduled and make sure it happens before final payment.
• Keep a copy of the permit and passed inspection report for your records — you'll need them when you sell the home.

Failure to permit roofing work can result in fines, forced re-roofing, or complications during a home sale.

6. Know Your Rights Under Delaware Consumer Law

Delaware law gives homeowners meaningful protections:

• You have the right to cancel a home improvement contract within 3 business days if it was signed at your home (Delaware's right of rescission, consistent with federal FTC rules).
• Contractors must provide a written notice of this right at signing.
• If a contractor violates the Home Improvement Contractor Act, you may have grounds to file a complaint with the Delaware DPR and pursue civil remedies.
• Delaware's Consumer Fraud Act (6 Del. C. § 2511) can apply to deceptive practices by contractors.

If you believe a contractor has defrauded you or done substandard work, you can file a complaint with the Delaware Attorney General's Consumer Protection Unit. Connect with our intake team to explore your options.

FAQ: Delaware Roofing Contractors

H3: Does a roofer in Delaware need to be licensed?

Yes. Roofing contractors performing home improvement work in Delaware generally must be registered as a Home Improvement Contractor (HIC) with the Delaware Division of Professional Regulation. Some local jurisdictions may have additional requirements. Always verify before hiring.

H3: Can I do my own roof in Delaware without a permit?

In some cases, minor repairs may not require a permit, but full roof replacements almost always do. Permit requirements vary by county and municipality. Contact your local building department to confirm before any work begins.

H3: What should I do if a Delaware roofer did bad work?

Start by documenting everything — photos, videos, the written contract, and all communications. Then file a complaint with the Delaware DPR and/or the Attorney General's Consumer Protection Unit. You may also have civil remedies under the Home Improvement Contractor Act. An attorney can help you assess your options.

H3: How much should I put down on a roofing job in Delaware?

Most reputable contractors ask for a deposit of 10–30% upfront, with the balance due at completion or in milestone payments. Be cautious of any contractor demanding full payment before work starts. Confirm all payment terms in your written contract.

H3: What warranty should I expect on a new Delaware roof?

Material warranties vary by manufacturer — some offer 20 to 50+ year coverage on shingles. Labor warranties from contractors typically range from 1 to 10 years, depending on the company. Get both warranties in writing before work begins, and confirm what voids each one.

Hiring a roofer in Delaware doesn't have to be stressful — but skipping even one step on this checklist can leave you exposed to costly problems. When in doubt, slow down and verify.
