Replacing a roof in Baltimore
Only about 15 percent of Baltimore's housing consists of detached single-family homes, and roughly 41 percent was built before 1940. That combination means many roofs in the city sit on older buildings where what lies beneath the surface is as important as the surface itself.
When you weigh a full replacement against more patching, consider how old the covering is, whether wear is visible across the entire roof, whether the deck has soaked up water and lost strength, and whether older layers are still in place under the current one. Any of these makes a tear-off the more durable answer. Once the old roofing comes off, ask the contractor what they will examine, from sheathing and flashing to ventilation, and how they will report it.
The local forecast zone recorded 18 winter storm or heavy snow events, so ask whether the plan includes an ice and water barrier near the eaves.
Make sure you also agree on the roofing material, the planned schedule, the manufacturer's warranty for the products, and the method for removing and disposing of the old roof. Permit requirements depend on the scope of work, especially if deck or structural work is involved, so confirm with the Baltimore City Department of Housing and Community Development (DHCD) - Permits and Code Enforcement.
