Roof repair in Pikesville, MD

Most leaks on houses like these come from one detail, and finding it costs far less than replacing the roof around it.

The split-levels and ramblers built in 21208 between 1950 and 1979 often have a rear addition with a low-slope roof, and the line where that roof meets the wall of the main house is a common leak point. The flashing there has to turn up the wall and tuck under the siding or into the brick, and sometimes it was done with sealant instead. Repairing that junction properly usually stops the leak without touching the rest of the roof. If the membrane itself has failed, it needs a membrane repair, not shingle.

On the main roofs of those houses, now on a second or third replacement, the chimney is the next suspect. Flashing reused through two reroofs is often the oldest metal up there. Bath and kitchen fans venting into the attic cause a different kind of damage, with stained or soft decking that looks like a leak from inside. We go up, photograph the actual cause, and price the repair as its own line before you decide anything.

The older houses are their own case. About 1,100 homes in 21208 predate 1940, and around Sudbrook Park and the Greenspring corridor slate is not unusual. A slipped or broken slate can often be replaced on its own, but matching depends on what is still available, and in Sudbrook Park appearance can be constrained, so we check first. In townhouse rows, where about one home in six is attached, a leak at the party wall may need the neighbor involved.
