The rules of the game in Maryland
Roofing and insurance are governed state by state — who may sell you a roof, what your deductible can look like, and how long you have to act all depend on Maryland law. Each item below cites where it comes from.
Roofer licensing in Maryland
Maryland licenses roofers at the state level. Roofing counts as "home improvement," so any contractor doing residential roof repair or replacement must hold a Maryland Home Improvement Commission (MHIC) contractor license, issued by the Maryland Department of Labor's Division of Occupational and Professional Licensing. Maryland's home improvement law sets no minimum dollar amount that triggers the license — the requirement applies to residential work regardless of the job's price. Before hiring, confirm a roofer's license is active using the state's free online "Check the License Status of a Contractor or Salesperson" lookup on the MHIC website.

Public adjusters in Maryland
In Maryland, anyone who negotiates your insurance claim on your behalf must be licensed as a public adjuster by the Maryland Insurance Administration, which requires passing a licensing exam and paying a $50 application fee. The adjuster's fee is not capped by law and is negotiable between you and the adjuster, but you have the right to rescind or cancel the signed contract within 10 business days, and the adjuster must return anything of value within 15 business days of receiving your cancellation notice. If your insurer pays or commits in writing to pay the full policy limit within 72 hours of loss notification, the adjuster cannot charge a percentage commission and may only receive reasonable compensation for the time spent and expenses incurred on the claim.

How wind & hail deductibles work here
In Maryland, homeowners policies may carry percentage-based deductibles tied to your Coverage A dwelling limit, and a mandatory hurricane deductible cannot exceed 5% of that limit unless the insurer has filed the higher underwriting standard with the Insurance Commissioner (at least 60 days in advance); you can also voluntarily buy a higher one. A mandatory hurricane deductible can only be applied during a window that starts when the National Hurricane Center issues a hurricane warning for any part of the state and ends 24 hours after the last such warning is terminated, no matter where your home is; ordinary wind or hail damage outside that window is subject to your regular deductible. Insurers using a percentage deductible must give you an annual statement explaining how it applies, plus a "Percentage Deductible Notice" at issuance and each renewal (its heading in at least 12-point type and the statutory explanation in at least 10-point type) stating the exact percentage, the circumstances that trigger it, and a worked example of how it applies to a loss. If you are hit by storm damage, check your declarations page to see whether a flat-dollar or percentage deductible applies before filing.

Matching: must the insurer replace undamaged shingles?
Maryland has no statute or regulation requiring an insurer to replace all undamaged aluminum siding to achieve a perfect match, but the Maryland Insurance Administration's long-standing position (MIA Bulletin No. 97-1, "Aluminum Siding Claims") is that under a replacement-cost homeowner's policy an insurer cannot ignore obvious mismatch between existing and newly replaced siding. Where new siding will not reasonably match the existing surface in color shade, texture, or dimensions, the MIA reads the policy to require the insurer to account for it — settlement options include moving undamaged siding from other areas of the house to blend the repair, replacing both damaged and undamaged siding on one or more sides, replacing all siding, and/or paying an allowance to reflect the diminution in the home's value caused by the mismatch. An insurer whose settlement practices fail to take major differences into account may be subject to action under Section 230A, Article 48A of the Code (Maryland's unfair claim settlement practices law), and insurers must inform insureds of any appraisal rights under the policy where there is disagreement on the amount of a covered loss. Note: this bulletin addresses aluminum siding hail claims specifically; it does not mention roofing, so it cannot be cited as authority that Maryland requires roof matching.

Deadlines that decide claims
In Maryland you generally have three years to file a lawsuit against your homeowners insurer (Md. Courts & Judicial Proceedings § 5-101), and under Maryland Insurance Article § 12-104 a policy clause that tries to shorten that period is against public policy, illegal, and void. Under COMAR 31.15.07.03, your insurer must acknowledge receipt of your claim within 15 working days and must affirm or deny coverage within 15 working days after you submit properly completed proof of loss. Under COMAR 31.15.07.04, if the company cannot complete its investigation of a first-party claim within 45 days, it must promptly notify you in writing of the actual reason more time is needed, and repeat that notice after each additional 45-day period until it affirms or denies the claim.
Insurer of last resort
Maryland has an insurer of last resort called the Maryland Joint Insurance Association (JIA), the state's FAIR Plan (established under the federal Fair Access to Insurance Requirements). If you have been unable to obtain essential property insurance through the competitive property/casualty marketplace, the JIA can issue one of three policy types — Homeowners, Dwelling Property, or Commercial Property. This coverage may be more restrictive and more expensive than a standard policy, and it does not cover flood. You can apply either through a licensed Maryland property/casualty insurance producer or directly with the JIA.
Buying or selling: what must be disclosed
Maryland is not a pure caveat emptor state for home sales: under Real Property §10-702, a seller of most single-family residential property must give the buyer, on or before signing the contract, either a Residential Property Condition Disclosure Statement listing defects the seller actually knows about or a Residential Property Disclaimer Statement selling the home "as is." Even a seller who chooses the disclaimer must still disclose any latent defects they have actual knowledge of — hidden material problems a buyer could not reasonably ascertain by a careful visual inspection and that pose a direct threat to health or safety. The disclosure form specifically covers structural systems including the roof, so a roof problem the seller knows about (such as active leaks or a roof a contractor has said needs replacement) must be disclosed. Sellers only have to reveal what they actually know; the law does not require them to undertake an independent investigation or inspection of the property.

What homeowners pay here
Maryland homeowners paid an average of about $1,392 per year for a standard HO-3 homeowners insurance policy in 2022 — somewhat below the national HO-3 average of $1,569 that year. Across all owner-occupied homeowners policy forms, the statewide average was roughly $1,372 (versus about $1,559 nationally). Use this as a benchmark: if your quote is far above it, shop competing carriers, and remember that raising your deductible or bundling with auto can lower the premium. These are averages, so your actual cost varies with your home's value, roof age, and claims history.
When the insurer won't move: file a complaint
In Maryland, homeowners file insurance complaints with the Maryland Insurance Administration (MIA), the state's insurance regulator. You can file online through the MIA's website (documents can be attached), by mail to the Consumer Complaint Investigation unit at 200 St. Paul Place, Suite 2700, Baltimore, MD 21202, or by emailing property and casualty complaints to pccomplaints.mia@maryland.gov; questions can be directed to 1-800-492-6116. If you believe your property and casualty or disability insurer failed to act in good faith when deciding a first-party insurance claim, you may file a separate action under Section 27-1001 of the Insurance Article by completing and submitting the MIA's Section 27-1001 complaint information sheet.

Worth knowing
Maryland's biggest roof-wind threat isn't only hurricanes and tornadoes — it's derechos, fast-moving straight-line windstorms. On June 29, 2012, one such storm (classified by the National Weather Service as a progressive derecho) swept across the region with measured peak gusts of 66 mph at BWI Airport, 71 mph at Dulles, and 70 mph at Reagan National, generating more than 300 damage reports in the Baltimore-Washington area and leaving 3.5 to 4 million customers without power, some for many days. Gusts in that range can strip shingles and drop trees onto roofs, so Maryland homeowners should inspect their roof after any severe summer thunderstorm line, not just named storms, since this wind damage is typically covered under a standard homeowners policy.
