Roofing in Mantua
What sets Mantua apart is that its roofs never shared a build-out. This is still a partly agricultural township — Duffield's, a fourth-generation farm on Chapel Heights Road in Sewell, works fields off the same roads as the subdivisions — and its housing arrived in separate waves rather than one boom. The 18th-century crossroads at Barnsboro anchors the oldest stock; the postwar decades filled the Sewell section with ranches, split-levels, and bi-levels; and later colonials went up on former farm fields. No single roof spec covers a township built this way, which is why the flashing and valley work matter more here than the shingle line anyone picks off a sample board.
The postwar homes are the biggest slice, and the split-levels and bi-levels are the hardest of them to keep dry, because their whole shape is offset. A low wing's roof runs straight into the two-story wall of the tall wing, and that junction only holds if the step flashing is layered shingle by shingle up the wall, a kickout diverter is set at its foot to throw runoff into the gutter, and counter flashing caps the top edge over the siding. Builders skipped the kickout constantly, and without it every hard rain drives water behind the siding rather than into the gutter, rotting the wall sheathing from the inside while the roof above still looks sound.
The shop sits a good two hours north of here in North Jersey, so a Mantua job is a planned trip south, not a same-week patch call. That distance is exactly why the roofs here suit how we operate: a seam-heavy split-level, a whole rear addition re-roofed to match, a masonry chimney rebuilt from the crown down are jobs worth doing in one visit, where it pays to strip the plane, correct the flashing, and reset the system rather than chase a stain. When the scope justifies the drive, we schedule the crew and the material for the full replacement or rebuild the roof actually calls for, planned and priced as a single trip. That is the honest fit between a statewide contractor and this stretch of Gloucester County.
From the Barnsboro Crossroads to the Greensand Quarry
Mantua's signature sits underground. The township's low ground is greensand marl, the green Cretaceous seabed that the old Inversand pit dredged for fertilizer and that Rowan's Edelman Fossil Park now works for a 66-million-year-old bone bed. Above that marl the land is low along Mantua Creek, wooded, and slow to dry, with the Tall Pines preserve holding old forest on the Deptford line. Older homes around Barnsboro and Carpenter's Landing — the creek's old shipping landing — have been added onto for generations, and every rear ell, dormer, and kitchen wing cut a fresh valley to line with metal and opened another roof-to-wall joint to flash. Their masonry chimneys are the other recurring leak: a cracked crown and counter flashing that has lifted out of the mortar joint let water straight down the flue, and any stack wider than a couple of feet wants a cricket on its up-slope side to split the runoff before it dams with leaves.
The newer end of Mantua is the colonials that replaced the farm fields, many of them going up from the 1990s onward on builder-grade roofs that are now aging out a few years apart. But there is no township-wide roof here to template. A Barnsboro-era steep pitch, a 1960s split-level, and a two-story colonial each want their own flashing plan and their own valley detail, and on the low, tree-shaded lots the north slopes stay damp long enough to grow moss and dark algae while leaf litter dams the open valleys and eave gutters. That mix is the real job in Mantua — reading which roof you are actually standing on before anyone orders shingles.

Common Mantua Roof Problems We Fix
Patterns we see again and again on Mantua roofs — most driven by the local housing stock and Gloucester County climate. If any of these sound familiar, give us a call for a free on-site assessment.
- Postwar split-levels and bi-levels around Sewell: rotted step flashing and a missing kickout diverter where a low wing's roof dies into the tall wing's two-story wall, sending water behind the siding instead of into the gutter.
- Older homes around Barnsboro and Carpenter's Landing: cracked masonry chimney crowns and counter flashing that has lifted out of the mortar joint, letting water run down the flue and into the ceiling below.
- Additions, rear ells, and dormers on the older stock: fresh valleys lined with corroded or under-lapped metal, plus chimneys wide enough to need an up-slope cricket that was never framed.
- Shallow-pitch ranches: split rubber pipe boots at the plumbing vents and backed-out ridge nails that open a leak years before the field shingles are worn through.
- North-facing slopes on the low, tree-shaded lots near the creek and the Tall Pines edge: moss and algae lifting shingle edges, with leaf-dammed valleys and gutters backing water under the drip edge.
