Baltimore's commercial building stock skews heavily toward flat or low-slope roofs, especially in industrial areas near the Port and older commercial districts like Greenmount and East Baltimore. Flat roofs drain slowly, and when a membrane fails or a drain clogs, water accumulates fast. A two-inch rain event can put thousands of gallons on your roof in an hour. Without immediate intervention, that water finds every seam, penetration, and weak point in your roofing assembly. The city's humid summers also mean that water trapped in insulation does not dry out quickly, leading to mold and structural rot that compounds repair costs.
