Lambertville Roofing, Chimney & Gutter Services in Hunterdon County, NJ

Roofing in Lambertville

Lambertville sits right on the Delaware, close enough that a bridge carries you on foot into New Hope on the Pennsylvania side, and the borough packs a remarkable amount of nineteenth-century building into a few dozen blocks. The duplex is the most common house here, making up roughly half the historic district, and streets like Swan run in near-continuous walls of attached Federal and Greek Revival brick and frame houses, put up from the 1830s on as workers' housing for the mills and the railroad. The larger Italianate and Second Empire homes climb North Union Street, the old Millionaires Row where the factory owners built, while the oldest houses and the antiques shops line Bridge Street down by the river. When houses touch each other like that, a roof is never quite its own roof; the plane you stand on drains toward a neighbor's wall, and the flashing that keeps the two apart is doing most of the work.

The Victorian houses here almost all carry box gutters, the built-in wooden trough tucked behind the cornice and lined with metal, invisible from the sidewalk. On an attached house there is nowhere for that trough to overflow except down the party wall or into the plaster of the top-floor rooms, so the lining is what stands between a bracketed cornice and a soaked ceiling. We check the outlets, the soldered seams, and the pitch of the trough itself, because a box gutter that has quietly gone flat holds water instead of moving it, and that standing water is where the rot behind the cornice starts.

The low blocks between the canal towpath, Swan Creek, and the river have taken real water over the years. Hurricane Floyd sent Swan Creek through roughly a hundred homes and put nearly two feet into the elementary school, and the 2004 Delaware flood ran the highest the river had reached since 1955. High water is a basement problem more than a roof one, but the moisture it leaves behind in old brick and stone does not drain off with the river. A masonry party wall or a chimney that goes into winter still wet will spall and lose its mortar joints to freeze-thaw, and once those joints open, the counter flashing let into them has nothing solid to grip. On these houses the chimney and the wall are part of the roof, and we treat them that way.

Roofs that run wall-to-wall down to the river

A good number of the grander Victorian houses here wear Second Empire mansards, that steep, near-vertical lower slope in slate or patterned shingle, capped by a nearly flat deck up top. Two different roofs are stacked on one house, and the two fail differently: the steep face sheds well for decades but loses individual slates and lets water in at the dormer cheeks, while the flat deck overhead is the part that actually leaks, usually where an old membrane or metal panel has been patched one too many times. Knowing which of the two is really the problem keeps you from paying to redo the half that is still sound.

Behind the main block, most of these houses grew a rear ell or a kitchen addition at a pitch too shallow for shingles to protect, and those want a proper flat-roof membrane or standing seam, not three tabs laid too low. Where the low addition meets the taller original house, you get a roof-to-wall joint that has to be carried up under the siding or let into the brick, and on a party-wall house that same joint can sit inches from the neighbor's structure. Getting the water off the back of these houses without dumping it against a foundation that already sits low to the creek is the part that takes real thought.
