How to Choose a Roofer in Maryland

How to choose a roofer in Maryland: verify the MHIC license, match the roofer to your roof type, follow the one-third deposit rule, and avoid storm chasers.

How to Choose a Roofer in Maryland

Maryland requires every roofing contractor to hold a Maryland Home Improvement Commission license, and that single fact should be the first filter you apply. The MHIC license means the contractor passed an exam, carries at least $50,000 in liability insurance, and contributes to the Home Improvement Guaranty Fund, which can reimburse homeowners up to $30,000 if a licensed contractor does defective work and fails to make it right.

Plenty of unlicensed crews still work in the state, especially after hailstorms in Frederick County or wind events along the Eastern Shore. They knock on doors, offer to "handle the insurance," and disappear once the deposit clears. Knowing what a legitimate Maryland roofer looks like makes those crews easy to spot.

Verify the MHIC License and the Insurance Behind It

The Maryland Department of Labor runs a public license search where you enter a contractor's name or license number and see the status, expiration date, and any disciplinary history. Every roofing quote in Maryland is required to display the MHIC number, so if it is missing from the paperwork, ask why.

Liability insurance and workers' compensation are the next two documents. The MHIC minimum of $50,000 is low for a roofing job, so ask for a certificate showing at least $1 million in general liability and confirm workers' compensation covers every person on the roof. If a worker falls off a two-story colonial in Columbia and the roofer has no comp policy, you become the deep pocket.

Call the insurance agent on the certificate. Certificates get forged, and a two-minute phone call confirms the policy is active and covers roofing rather than, say, landscaping.

What the Guaranty Fund Does and Does Not Cover

The Home Improvement Guaranty Fund reimburses actual losses caused by a licensed contractor's incomplete or defective work, up to $30,000 per claim, after you have tried to resolve it with the contractor. It applies only to licensed contractors, so hiring an unlicensed crew forfeits that protection entirely.

The fund does not cover cosmetic disagreements or projects that simply went over budget. It also requires a claim within three years of the work, so keep your contract and payment records.

Match the Roofer to Your Roof Type

Asphalt shingles cover most Maryland homes, and any licensed roofer can handle them. The differences show up on other materials: standing seam metal on a farmhouse in Carroll County, slate on a rowhouse in Baltimore's Bolton Hill, cedar shake in Annapolis, or a flat modified bitumen roof on a Federal Hill rowhome.

A shingle roofer who "also does" slate is a risk. Slate and tile require different fasteners, different flashing techniques, and a crew that knows how to walk the roof without cracking it. Ask how many roofs of your material the company installed in the past year and ask to see two of them.

Flat and low-slope roofs are their own specialty. Baltimore City and the older neighborhoods of Hyattsville and Takoma Park are full of them, and the common failures involve ponding water, poor drainage, and seams that were heat-welded badly. A roofer who mostly does pitched shingle work in Howard County suburbs is not the right call for a flat roof.

Get the Estimate in Writing and in Detail

A Maryland roofing estimate should list the shingle brand and line, the underlayment, the ice and water shield coverage, the flashing plan, ventilation changes, tear-off and disposal, and the warranty terms. A one-page quote that says "replace roof, $12,000" leaves too much room for substitution.

Ice and water shield is a specific Maryland concern. Winters in Frederick, Hagerstown, and Westminster produce enough ice damming that most roofers install it along eaves and in valleys, and the better ones extend it 24 inches inside the exterior wall line. Confirm where it is going.

Ventilation is the other line to check. Many Maryland homes from the 1970s and 1980s in Bowie, Severna Park, and Silver Spring have undersized attic ventilation, and a roofer who replaces the shingles without addressing it is setting up the new roof to cook in July.

Comparing Three Quotes Fairly

Line up the quotes by material and scope, not by total. A $14,000 quote with architectural shingles, full ice and water shield, new ridge vent, and a 25-year workmanship warranty is a better deal than a $10,500 quote with three-tab shingles and a two-year warranty.

Ask each roofer what happens if they find rotted decking. Replacement plywood runs $70 to $120 per sheet installed in Maryland, and a quote should state that rate up front rather than leaving it as a surprise on day two.

Understand Maryland's Contract and Deposit Rules

Maryland law caps home improvement deposits at one-third of the contract price, and the contract itself must include the MHIC number, a description of the work, start and completion dates, and a notice of your right to cancel within three business days if the contract was signed in your home. A roofer who asks for 50% up front is breaking the law.

Payment schedules should track progress. A common structure is one-third at signing, one-third when materials are delivered, and the balance after final inspection. Never pay the final installment before you have walked the property, checked the gutters for debris, and confirmed the magnet sweep for nails was done.

Read the warranty section twice. Manufacturer warranties on shingles are separate from the roofer's workmanship warranty, and the manufacturer warranty often requires a certified installer to be valid. If a roofer claims a 50-year warranty, ask which part of it is theirs and which part belongs to GAF or Owens Corning.

Storm Damage and the Contractors Who Follow It

Maryland gets enough hail and wind, especially in the central counties and along the Chesapeake, that storm-chasing roofers are a recurring problem. They arrive after a June thunderstorm in Gaithersburg, offer a free inspection, and find damage whether it exists or not.

Do not sign anything that assigns your insurance claim or benefits to the contractor. Maryland regulates these assignment-of-benefits arrangements, and once you sign one, you have handed control of the claim to a company you met an hour ago.

Get your own inspection first. A local roofer with a Maryland address and a five-year track record can tell you whether the hail damage is real, and your insurer will send an adjuster regardless. A legitimate storm claim does not need a stranger's help to file.

Ask where the company was based two years ago. A roofer registered in Texas with a temporary Maryland office in Frederick will not be around to honor a workmanship warranty in 2031.

Local Reputation Beats Online Ratings

References from the past year in your county are the most reliable signal. Roofing quality varies crew to crew, and a company with a great reputation in Anne Arundel County may be sending a new subcontracted crew to your job in Harford County.

Ask whether the crew that shows up is employed by the company or subcontracted. Subcontracting is common and not automatically bad, but you should know who is on your roof and whether the subcontractor is covered under the roofer's insurance.

Drive past a job in progress if you can. A tidy site with tarps over the landscaping, a dumpster placed on plywood to protect the driveway, and a crew wearing fall protection tells you more than any review page.

Frequently Asked Questions

How do I check if a roofer is licensed in Maryland?

Search the Maryland Department of Labor's MHIC license lookup by company name or license number. The result shows whether the license is active, when it expires, and whether the contractor has any public complaints or disciplinary actions.

How much deposit can a Maryland roofer ask for?

State law limits the deposit to one-third of the total contract price. A roofer requesting half or more up front is violating the Maryland Home Improvement Law, and that alone is a reason to walk away.

Should I hire a roofer who came to my door after a storm?

Be cautious. Some door-knockers are local and legitimate, but many are out-of-state crews who leave after the storm season. Verify the MHIC license, ask for a local physical address, and get a second opinion before signing any inspection agreement or assignment of benefits.

What warranty should I expect on a new roof in Maryland?

A workmanship warranty of at least 5 years from the roofer is standard for quality contractors, and 10 to 25 years is common among manufacturer-certified installers. Shingle manufacturer warranties run 25 to 50 years but cover only material defects, not installation errors.

Does Maryland require a permit for roof replacement?

Most Maryland counties and municipalities require a building permit for a full roof replacement, and some require one for repairs beyond a certain size. The roofer should pull the permit, and the cost, typically $50 to $250, should appear on the estimate.
