Parapet mortar and flashing
On Trenton's rows, the counter-flashing lives in a mortar joint. When the joint opens, the flashing fails with it — repointing and re-flashing are one job, scoped together.

Trenton wears its history in brick: the rowhouses of Chambersburg and South Trenton, the twins of Villa Park, the grander blocks of West Trenton and Hiltonia — a capital city's housing built across two centuries along the Delaware. The roofs match the eras: flat and low-slope systems behind rowhouse parapets, pitched shingle roofs on the detached stock, and on the oldest streets, survivors from the slate age still on duty.
The work here runs from rowhouse drainage and party-wall joints to full replacements on the detached streets, and it is carried out with respect for what these buildings are. Sixteen Trenton ZIP codes — spanning 08608 through 08691 — are covered by this service, and one call connects Trenton homeowners with a local roofing professional who reads brick-city roofs fluently.
Trenton sits in the Delaware's bend, and its weather has a river's moods: fog that keeps north slopes damp into the afternoon, summer storms that boil up the valley, and winter freeze that works the mortar of a thousand parapets. Those parapets are Trenton's quiet roofing story — as mortar joints open with the decades, water enters the wall top and appears, confusingly, as a roof leak in the room below. Reading a Trenton rowhouse means reading its brick as carefully as its membrane.
Chambersburg's tight rows add the shared-drainage reality: rear roofs often shed toward shared alleys and boxes, and one blocked box can pond two roofs. The local habit is to inspect the drainage path to the alley, not merely to the property line.

The Burg's dense brick rows share party walls, parapets, and rear drainage. Leak diagnosis here always includes the joints the neighbors share.
The twins and singles of Villa Park carry pitched roofs over early-1900s frames — plank decks, dormers, and porches whose little roofs fail first and are repaired as their own projects.
West-side Trenton's bigger homes carry complex roofs — multiple valleys, chimneys, and additions — maintained on an inspection rhythm rather than a crisis rhythm.

The diagnosis checks the parapet and joints before condemning the membrane — and the repair scopes brick and flashing as one detail.

Where the membrane field is sound, yes — seams, drains, and parapet joints are repairable, and most rowhouse leaks live exactly there. Layered, saturated roofs are the honest exceptions, and the inspection will show you the moisture evidence either way.
