Roofing in West Windsor

West Windsor grew up around the Princeton Junction station on the Northeast Corridor, and once the old farm fields were subdivided, most of what went up was large: four-, five-, and six-bedroom colonials on generous lots in developments like Grovers Mill Estates and Heatherfield. A house that size almost never gets a simple roof. The main gable crosses a hip over the garage wing, a pair of dormers break the front slope, and a bay window carries its own small roof, all of which means far more valleys and sidewall transitions than a plain gable ever carries.

Many of these houses date to the 1980s and 90s, built with skylights over the stairwell or family room, a full run of plumbing vent stacks, and bath and kitchen exhaust punched through the deck. That first generation of skylights is now the usual source of trouble, not the glass itself but the head flashing and the counter-flashing over the curb, along with pipe boots baked hard and split by decades of sun. Because the household tends to be out the door early for the train and back late, a lifted skylight apron can drip into attic insulation for weeks before a stain ever reaches a ceiling.

The newer subdivisions sit on open former farmland with little mature canopy on the windward side, so wind-driven rain gets pushed up under ridge caps, hip shingles, and rake edges before it can shed. On a roof this complicated, most leaks trace back to a flashing or a penetration long before the shingles across the main slopes wear out, so the honest fix is often rebuilding a chimney cricket or reflashing a skylight curb while good shingle still has years of service left. When the shingles genuinely are done, we will say so.

Where these roofs actually give out

The big colonials here usually carry a wide masonry chimney, and some carry two. A chimney that wide needs a cricket, a small peaked saddle set on the high side that splits water around the stack, and a lot of the original builder work either skipped it or framed it too shallow. When it is missing, leaves and grit pack in behind the chimney and stand against the counter flashing let into the mortar, which is exactly where the water works in. The dormer cheek walls tell a similar story: step flashing set into each course does the real work there, and it is the piece that gets face-nailed or caulked over during a cheap reroof.

All that roof shape also concentrates water into long valleys, and what decides whether a valley lasts is what sits under it: an ice-and-water membrane and a proper metal liner carrying the flow. A cheaper crew laces shingles straight across the open gap and skips the liner, and that is the valley that opens up first. The same membrane matters at the eaves and around every penetration, where it is the last defense once wind or ice backs water uphill. And because these floor plans put a lot of attic under a lot of roof, the ventilation has to stay balanced between the ridge and the soffits, or the deck sweats in winter and the shingles cook the granules off in summer.
