Steps
Go to labor.maryland.gov/license/mhic/ and follow the link to the Home Improvement Public Query (hosted on the dllr.state.md.us Electronic Licensing system)
Search by contractor personal name, contractor trade name, business location, salesperson name, or license/registration number
Review the returned record for license status, and check for any listed complaints or disciplinary history tied to that license number
For salespeople working under a licensed contractor, verify the salesperson record separately using the salesperson-name search option
If online results are ambiguous, call the Maryland Department of Labor's Division of Occupational & Professional Licensing at 410-230-6231 to confirm status directly
Cross-reference the license number provided on any contract or estimate against this lookup before signing, since Maryland explicitly recommends verifying before hiring
Known gotchas
The public query tool sits on the legacy dllr.state.md.us domain even though the program's landing page has moved to labor.maryland.gov — bookmark both, since links to the old domain still work but are not the primary marketing page
MHIC licensing covers home improvement generally; it is not roofing-specific, so a search will return contractors licensed for any home improvement trade, not just roofing/siding/gutters
Search by exact license number when possible — name-based searches can return multiple similarly named businesses and require manual disambiguation
