How to Find an MBE or WBE Certified Roofing Contractor in Maryland for Government Projects

Maryland public work runs on participation goals. Whether you are a procurement officer at a state agency, a prime contractor building a bid, a county facilities director, or a developer using public funds, the roofing scope is often one of the cleanest ways to move an MBE or WBE number — roofing is a self-contained, well-defined package with real dollars attached. The difficulty is not finding companies that say they are certified. It is finding a certified roofer whose credential matches your funding source, covers roofing as a work category, is currently active, and belongs to a firm that can actually weld a watertight seam on a 40,000-square-foot low-slope roof. Here is the process, step by step.

uick Answer

To find an MBE or WBE certified roofing contractor in Maryland for a government project, start with the funding source, because it determines which certification counts. For state-funded work, search the MDOT Office of Minority Business Enterprise directory at mbe.mdot.maryland.gov and filter by the roofing NAICS code, 238160. For federal work, search SAM.gov and the SBA’s small business search for 8(a), HUBZone, WOSB/EDWOSB, and SDVOSB firms. For county and city projects — Montgomery County, Prince George’s County, Baltimore City — check that jurisdiction’s own certified vendor directory, since local programs do not always accept state certification. Then verify three things before you award: that the certificate is active and not expired, that roofing is listed as an approved work category, and that the firm has the bonding, manufacturer certifications, and safety record to perform the scope itself.

Step 1: Identify who is funding the project

This is the step people skip, and it is the one that causes bid rejections. “MBE certified” is not a single, portable status in Maryland. It is a set of separate programs, each with its own certifying body, its own directory, and its own rules about what earns participation credit.

State-funded contracts fall under Maryland’s Minority Business Enterprise program, certified by the Maryland Department of Transportation’s Office of Minority Business Enterprise (MDOT OMBE) on behalf of the entire state. Federally funded contracts — including federally assisted transportation work — run on the Disadvantaged Business Enterprise (DBE) program under 49 CFR Part 26, or on SBA socioeconomic programs such as 8(a), HUBZone, and Women-Owned Small Business. County and municipal projects frequently operate their own local programs with their own certification lists.

Before you search a single directory, read the solicitation. It will name the program, the participation goal, and any subgoals. Match your search to that language.

Step 2: Search the right certification directory

For Maryland state-funded work: the MDOT directory

MDOT OMBE is the single certifying agency for Maryland’s MBE, DBE, SBE, and ACDBE programs, which means one certification is recognized across state agencies rather than agency by agency. The public directory at mbe.mdot.maryland.gov lets you search by company name, county, certification type, and — critically — by work category.

The Governor’s Office of Small, Minority & Women Business Affairs (GOSBA) oversees the broader framework, including the Small Business Reserve (SBR) program and the Veteran-Owned Small Business Enterprise (VSBE) program. SBR status is self-certified through eMaryland Marketplace Advantage (eMMA), the state’s procurement portal, which is also where you will find solicitations and registered vendors.

For county and city work: local directories

Maryland’s larger jurisdictions run their own programs and maintain their own lists. Montgomery County operates a Local Small Business Reserve Program alongside its minority, female, and disabled-owned business program. Prince George’s County administers an MBE program through its supplier development and diversity function. Baltimore City certifies MBE and WBE firms through its Minority and Women’s Business Opportunity Office.

Some of these jurisdictions extend reciprocity to MDOT-certified firms; some do not. Never assume. Confirm with the issuing office whether a state certificate satisfies the local requirement, and get the answer in writing before you build a bid around it.

For federal work: SAM.gov and SBA

Federal projects — and the DMV has a lot of them — require registration in SAM.gov with an active Unique Entity ID. From there, the SBA’s small business search tools identify firms holding 8(a) Business Development, HUBZone, Women-Owned Small Business (WOSB), Economically Disadvantaged WOSB, and Service-Disabled Veteran-Owned Small Business status. WOSB and EDWOSB certifications are issued through certify.sba.gov. Note that federal agencies operate under statutory small business contracting goals, including a long-standing target of at least 5% of federal contracting dollars to women-owned small businesses.

Step 3: Filter by the roofing work category, not just “construction”

Certification in Maryland is granted by work category, and this is where a promising search result quietly falls apart. A firm certified only under a broad general-construction code may not have roofing listed on its certificate. If roofing is not an approved category, the roofing subcontract may earn no participation credit at all — even though the company is a legitimate, properly certified MBE.

The code you want is NAICS 238160, Roofing Contractors. Related codes appear on some certificates depending on scope: 238170 (siding), 238390 (other building finishing), and 236220 (commercial and institutional building construction) for firms that self-perform roofing inside a general contracting scope. When you open a directory listing, read the work categories line by line, and if the scope includes sheet metal, coping, or edge metal, confirm those are covered too.

Step 4: Verify the certificate is active and correctly issued

A certificate is a snapshot, not a permanent condition. Firms graduate out of size-based programs, let recertifications lapse, change ownership, or get decertified. MDOT requires periodic recertification and affidavits of continued eligibility; the SBA’s 8(a) program has a nine-year term; WOSB and DBE statuses carry their own renewal cycles.

Verify three things at the time of award, not at the time of outreach:

• Active status and expiration date in the issuing body’s directory — not a PDF the vendor emailed you.
• The certifying body matches your funding source — an MDOT MBE certificate does not automatically earn Prince George’s County credit, and a private WBENC certificate does not earn state MBE credit.
• Roofing is an approved work category on that specific certificate.

Print or screenshot the directory record and date it. That record belongs in your compliance file.

Step 5: Confirm the firm can perform a commercially useful function

Both federal DBE rules and Maryland’s MBE program apply a commercially useful function standard. The certified firm must actually perform, manage, and supervise a distinct scope of work — running its own crews, procuring the membrane and insulation, and carrying the risk. A certified company that lends its name to a subcontract another crew performs is a pass-through. It earns no credit and exposes the entire project team to serious consequences, including liquidated damages, contract termination, and debarment from future public work.

Structure the roofing subcontract to survive that review. The certified roofer should hold the material purchase orders, employ the crews on site, control the schedule, and appear on the daily reports. Keep the certificate, the executed subcontract, invoices, and photographic documentation of the firm’s own crews on the roof. Good documentation is not bureaucratic overhead here — it is the evidence that your participation credit is real.

Step 6: Vet the roofer on technical merit, exactly as you would anyone else

Certification describes ownership and control. It says nothing about whether a firm can detail a parapet or hold a 20-year warranty. Apply the same commercial criteria you would apply to any bidder:

• Manufacturer certifications. Credentials such as GAF Master Select or Versico/Carlisle Authorized Applicator status are what unlock the long-term NDL system warranties — commonly 20 to 30 years — that protect a public asset over its life cycle.
• Bonding and insurance capacity. Maryland public work generally requires payment and performance bonds, plus general liability and workers’ compensation at the limits specified in the solicitation. Ask for a bonding letter with aggregate capacity, not just a single-project number.
• Safety performance. Request the experience modification rate (EMR) and confirm OSHA 10 and OSHA 30 training for crews and supervisors. Roofing is a high-hazard trade and public owners carry the reputational risk.
• Prevailing wage experience. Maryland’s prevailing wage law generally applies to state-funded public works above a statutory threshold, and Davis-Bacon applies to federal projects. Certified payroll is a real administrative burden — confirm the firm has done it before.
• System expertise for Maryland’s climate. TPO (45-, 60-, or 80-mil), EPDM, PVC, modified bitumen, and silicone restoration coatings each behave differently under Maryland’s freeze-thaw winters, humid summers, and periodic nor’easters and derechos. Most public buildings in the state are low-slope with interior drains and parapets, where ponding water, fastening patterns, and edge-metal detailing decide whether a roof lasts 12 years or 25.

How Premier Group supports Maryland government roofing projects

Premier Group Roofing & Construction is a minority-owned and women-owned commercial roofing and general contracting firm serving Maryland, Washington DC, Virginia, Illinois, and Florida. For agencies, prime contractors, and facility owners working against participation goals, that means the diversity objective and the roofing performance objective do not have to be a tradeoff.

What that looks like on a project: a free commercial roof assessment with full photographic documentation of existing conditions, a system recommendation grounded in your building’s drainage, code requirements, and capital plan rather than a one-size-fits-all spec, and manufacturer-certified installation that keeps the long-term warranty intact. Premier Group works in TPO, EPDM, PVC, modified bitumen, and restoration coatings, and coordinates the way public-sector clients need — defined timelines, transparent reporting, and minimal disruption to building occupants and operations. Because the team operates across several states and certification frameworks, Premier Group understands how participation credit gets documented and audited, so the compliance file is as clean as the finished roof.

Next steps

If you are scoping a roof replacement, restoration, or repair package on a Maryland public project, work the sequence in order: identify the funding source, search the directory that funding source recognizes, filter by NAICS 238160, verify the certificate at the time of award, and vet the firm’s bonding, safety, and manufacturer credentials before you commit. That sequence protects both your participation goal and your building.

Premier Group will assess your roof at no cost, document its true condition with full photographic reporting, and give you a system recommendation and clear scope you can take straight into your procurement process.
