Roof fire at Upper Marlboro warehouse quickly contained, no injuries

Smoke and roof flames at a warehouse in Upper Marlboro were knocked down quickly Saturday morning, limiting what could have become a larger industrial fire in the Queens Court West area near Route 301. Prince George’s County Fire/EMS said the blaze broke out at a 1-story commercial building in the 16100 block of Queens Court, and no injuries were reported.

Fire investigators remained on scene after crews contained the fire, leaving open key questions about how it started, whether any hazardous materials were involved and how much damage the roof sustained. The building sits inside the National Capital Business Park industrial area, a logistics-heavy development that has been marketed as a major distribution hub for Upper Marlboro and the surrounding county.

The broader park has been described in property materials as a development of about 2.7 million to 3.1 million square feet at full build-out across more than 440 acres. Turnbridge, which has listed the asset as Queens Court and Prince Georges Boulevard in Upper Marlboro, describes the site as a 442-acre industrial project with 3.1 million square feet. That scale matters because even a fire that stays on one roof can affect access, deliveries and work schedules across nearby warehouse tenants and contractors.

Prince George’s County Fire and Emergency Medical Services Department is one of the busiest combination fire departments in the country, responding to more than 400 incidents a day and about 200 structure fires a year. That gives context to Saturday’s response: crews regularly handle commercial blazes, but warehouses can still demand rapid deployment because fire can spread through roof assemblies, loading areas and stored goods before it is fully isolated.

Upper Marlboro has seen similar warehouse emergencies before. In 2018, a fire at 12601 Old Marlboro Pike was reported as a two-alarm warehouse blaze with no injuries, and operations continued through the night while crews worked the scene. That history underscores why even a contained roof fire in this part of the county gets immediate attention from investigators and neighboring crews.
