How to Choose a Metal Roofing Contractor in Southern Maryland

A metal roof can last 50 years or more, but only if it's installed right. The panels themselves rarely fail. What fails is the work: fasteners driven at the wrong angle, flashing that wasn't sealed, trim that lets wind-driven rain in. That's why choosing the contractor matters as much as choosing the metal.

If you're getting quotes for a metal roof in Calvert, St. Mary's, or Charles County, here's what to check before you sign anything.

1. Confirm the Maryland Home Improvement Commission (MHIC) License

In Maryland, anyone doing roofing work on your home must hold a license from the Maryland Home Improvement Commission. Ask for the MHIC number and look it up yourself through the Maryland Department of Labor. It takes two minutes.

This matters for more than paperwork. Hiring a licensed contractor gives you access to the MHIC Guaranty Fund, which can compensate homeowners for certain losses caused by licensed contractors. Hire someone unlicensed and that protection disappears.

While you're at it, ask for a certificate of liability insurance and confirm workers' compensation coverage. If someone gets hurt on your roof and the contractor isn't covered, it can become your problem.

2. Ask Which Metal Roofing Systems They Install

"Metal roof" covers several very different products. A good contractor will explain the options and recommend one based on your home, not just quote whatever they always install.

• Standing seam: panels joined with raised seams and hidden fasteners. The premium option, with the longest service life and the cleanest look.
• Exposed-fastener (screw-down) panels: screws go through the face of the panel. Lower cost and common on pole barns and outbuildings, but the rubber washers on the screws age and need checking over time.
• Metal shingles and stone-coated metal: made to look like traditional shingles or shakes while keeping metal's durability.

If a contractor can't clearly explain the difference, or pushes screw-down panels onto a house where standing seam makes more sense, keep looking.

3. Ask About Gauge and Coating

Two quotes can look the same until you check the specs. Ask every contractor to put these in writing:

• Panel gauge. Lower numbers mean thicker metal, so 26-gauge is heavier than 29-gauge. Thicker panels resist dents and hold up better in wind.
• Paint system. Premium PVDF finishes (often sold under the Kynar 500 name) hold their color and resist chalking much longer than standard SMP paint. In Southern Maryland's sun and humidity, that shows up within a few years.
• Underlayment. A quality synthetic underlayment under the panels is your backup against condensation and wind-driven rain.

A lower price often comes from thinner metal or a cheaper paint system, so compare specs, not just totals.

4. Get Both Warranties in Writing

A metal roof usually comes with two separate warranties, and you should see both:

• Manufacturer's warranty on the panels and paint finish. Ask what it covers (fading, chalking, perforation) and for how long.
• Workmanship warranty from the contractor on the installation itself. This is the one that covers leaks from flashing, fasteners, and trim.

A long paint warranty means little if the installer only stands behind their work for a year. Ask how long the workmanship warranty lasts and how warranty calls are handled.

5. Look at Local Work and Real Reviews

Ask to see metal roofs the contractor has installed nearby, ideally a few years old so you can see how they've held up. Local contractors understand what Chesapeake Bay weather does to a roof: summer humidity, nor'easters, and the occasional hurricane remnant pushing rain sideways.

Check reviews on Facebook and other sites, and read what customers say about how problems were handled, not just the star rating.

6. Know What Maryland Requires in Your Contract

Maryland law protects homeowners with specific contract rules. According to the Maryland Home Improvement Commission, your written contract must include the contractor's name, address, and MHIC license number, a description of the work and materials, and start and completion dates.

Maryland also limits deposits: a contractor cannot take more than one-third of the contract price up front, and cannot take any payment until the contract is signed. A contractor asking for half or more before starting is a red flag.

7. Watch for These Red Flags

• Showing up uninvited after a storm and pressuring you to sign today
• No MHIC number, or one that doesn't check out
• A deposit over one-third of the price, or cash only
• Vague quotes with no gauge, coating, or underlayment listed
• No written workmanship warranty

Frequently Asked Questions

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

Ask for their MHIC license number and verify it through the Maryland Department of Labor's license lookup. Home improvement contractors in Maryland must be licensed by the Maryland Home Improvement Commission.

How much deposit should a roofer ask for in Maryland?

No more than one-third of the contract price. Maryland law caps home improvement deposits at one-third and prohibits any payment before the contract is signed.

How much does a metal roof cost in Southern Maryland?

Installed metal roofing in Southern Maryland typically runs about $9 to $16 per square foot, depending on the system, the panel gauge, the roof's pitch and complexity, and whether old roofing is torn off. See our metal roofing page for how metal compares with asphalt.

Is standing seam better than screw-down metal roofing?

For most homes, yes. Standing seam hides its fasteners and lasts longer with less maintenance. Screw-down panels cost less and work well on barns and outbuildings, but the fastener washers need periodic inspection.
