Roof Repair in East Orange, NJ: Keeping Century-Old Two-Families, Mansions and Apartment Blocks Dry

On a two-family from East Orange’s railroad-suburb years, the rear roof leaks because it was designed for metal or rolled roofing and later covered with materials that need more slope. The houses of Ampere, Greenwood and Elmwood were built quickly for working families and renters after stations like Ampere opened in 1890. Builders gave them a pitched front facing the street and a nearly flat rear over the kitchens, often finished in soldered tin. Tin on a low slope works when it is painted and maintained. Over the twentieth century, most of it was covered with rolled roofing, tar coatings or shingles.

Asphalt shingles on a very low slope let wind-driven rain and winter meltwater run back under the laps. Every patch adds weight and traps moisture against the old board sheathing, which softens at the eaves and around chimneys. By the time an owner calls, the problem is rarely one hole. It is a section that has been fighting its own design for decades.

The durable answer is to strip that rear section to the boards, replace any that are soft, and install a membrane made for low slope, usually modified bitumen or a single-ply membrane, with a metal or membrane detail where it meets the shingles on the front pitch. That transition is where cheap jobs fail. We also look at the leader below, because a new rear roof that drains into a cracked leader on a narrow side yard sends water into your basement or your neighbour’s.

If the house is detached and the boards are sound, the work is ordinary maintenance under state rules. Replacing boards, or working on an attached two-family, needs a permit from the city’s Department of Code Enforcement, and we include that in the quote. You get photos of each stage, from the old layers to the finished membrane, as a record for tenants, insurers or a future buyer.

The large houses of Presidential Estates and Doddtown were built with materials meant to be maintained for generations, and repairing slate, copper and box gutters usually costs far less over time than replacing them with asphalt. These were houses for families who commuted by rail and wanted space and shade: cross gables, dormers, tall brick chimneys and, on many, slate or clay tile with copper valleys.

Slate often outlasts its fasteners. When the original iron nails rust, slates slip; when a limb falls, a few crack. Each can be replaced individually with matching stone held by copper slate hooks or nails. Worn valleys can be relined in copper. Walking on slate breaks it, so we work from hooks, ladders and roof brackets. Where an earlier owner patched with asphalt shingles or tar, we remove the patch and restore the slate, since those mixed spots are frequent leak sources.

Box gutters are the second issue. Built into the eaves and lined with metal, they look like part of the cornice. After decades of freeze-thaw their seams open, and water rots the rafter tails and runs into top-floor rooms. Relining with new metal or a membrane keeps the original eave line. Hanging a separate gutter over a failed box gutter changes the look and often hides active rot.

Chimneys are the third. Wide chimneys built for coal furnaces and fireplaces take a beating at their base, and the flashing and crown fail first. New step and counter flashing, a cricket on the uphill side and a proper cap on unused flues solve most leaks. Last come the trees that gave the neighbourhood its character. A late-autumn valley and gutter cleaning, and trimming limbs over the roof, prevent both ice dams and tree-strike damage.

East Orange’s older apartment buildings leak mainly at three points their builders could not have anticipated: drains facing modern rainfall, parapets after eighty winters, and equipment added to the roof decades later. As the city became a place of renters, brick walk-ups and elevator buildings rose along Main Street, Prospect Street and South Harrison Street and in Elmwood near the Newark line. Most were finished with built-up tar and gravel roofs behind masonry parapets, drained by one internal drain or a scupper.

Start with the drains. A single drain sized generations ago, with no overflow, ponds the moment leaves or debris block it. During Ida on September 1, 2021, when Newark next door recorded 8.41 inches, roofs like this filled behind their parapets within hours. We clear and test drains, replace strainers, check that the internal leader is not cracked and add an overflow scupper where the wall allows.

Next, the parapets. Stone or terracotta caps with open joints, washed-out mortar and failed counter flashing let water into the wall, where it shows up as a stain in an apartment well away from the real entry. Resetting caps or adding metal coping, repointing and new counter flashing fix leaks no roof patch can.

Finally, the add-ons: rooftop units, satellite mounts, vent stacks, bulkhead doors and skylights, each set into a roof that was never planned for them. Pitch pans dry out and curbs lose their flashing. We inspect and reseal or rebuild each one. Newer buildings along South Harrison Street and Evergreen Place use TPO or EPDM, but the same weak points apply. Multi-unit roof replacement and deck work need a city construction permit, and owners get a written scope and photo report to share with managers or lenders.

Many East Orange roof leaks come from changes made between the 1940s and 1970s, when houses were re-sided, attics were turned into rooms and whole blocks were reshaped by the Garden State Parkway and I-280. The city’s population peaked at 79,340 in 1950, and old houses were adapted to hold more people. Attics became bedrooms or apartments, dormers were added, and frame houses were wrapped in asbestos shingle, aluminum and, later, vinyl siding.

Each of those changes left a weak point. Dormers built quickly often have thin framing, little or no flashing at their cheek walls, and valleys where the dormer roof meets the main roof that were simply lapped with shingles. When siding went over the old clapboard, the step flashing where porch and rear roofs meet the walls was usually left in place or cut short. That flashing has now rusted through, and water runs behind the siding into the wall.

Fixing it properly means opening the siding. We remove a course or two, install new step flashing and counter flashing, and reset or replace the siding so the joint sheds water again. On dormers we rebuild the cheek-wall flashing and valleys and check the framing from inside. Roofers who only work on the shingle surface miss these, which is why the same leak returns after every patch.

In Greenwood, where the highways cut through, many surviving houses lost neighbours and gained exposed side walls that were never meant to face weather. Those walls and the roof edges above them deserve a close look. We document what we find with dated photos so you can see the cause, and repairs carry our 2-year written workmanship warranty.

Because East Orange inspects homes at sale and rental units for habitability, an old roof with an active leak can delay a closing or a new lease. The city lists applications for a Certificate of Occupancy and a Certificate of Continued Occupancy among its building forms, and a Certificate of Habitability among its Housing and Inspections forms. Inspectors look for conditions affecting safety and habitability, and a water-stained or sagging ceiling under a century-old roof invites questions.

For sellers, a roof inspection before listing is cheap insurance. Ours is free and comes with dated photos and a written condition report on the main, rear and porch roofs, chimneys, flashing, box gutters and what we can see from the attic. If something needs fixing, you get an itemized quote and can repair it before the city inspection or negotiate with the buyer knowing the facts.

For buyers, the report tells you which era of roof you are buying. A two-family with two shingle layers over soft board sheathing and a tar-coated rear roof is a different purchase from one with a recent tear-off and membrane. Ask the seller for records of past roof work, including the contractor’s 13VH registration number, and check it on the state Division of Consumer Affairs site.

For landlords, a leak over a tenant becomes a habitability issue quickly. Tenant and rent matters in East Orange run through the city’s Division of Rent Leveling and housing inspectors, so keep a record of when a leak was reported and when it was fixed. Our written scope and photos give you that record. We do not file city applications for you, but our documentation is written so you can hand it to an inspector or attorney.
