Roof Repair in Chatham, NJ: Slate, Cedar and Shingle Roofs in Chatham Borough

Most roof repairs on a house in Chatham’s Main Street Historic District count as ordinary maintenance, which the Borough code excludes from Historic Preservation Commission review, as long as you use in-kind materials and workmanship. The district includes houses spanning more than a century and a half, from the gambrel-roofed Parrot House at 47 Main Street and the Georgian William Day House at 70 Main to the Greek Revival Dusenberry House at 186 Main and the Carpenter Gothic Bower-Lum House at 427 Main, with its fish-scale patterned slate.

What counts as in-kind? Replacing broken slate with matching slate, re-flashing a chimney in copper, rebuilding a box gutter in its original form or replacing cedar shingles with new cedar of the same profile. These return the roof to its prior condition and need no review. What needs review? Changes visible from a public right-of-way that affect character-defining features: replacing slate with asphalt, adding dormers or skylights on the street side, or removing a decorative cornice. For those, the commission prepares a Historic Preservation Review Report and its recommendations go through the Planning Board within 45 days.

If a storm damages your roof, the code allows emergency repairs needed for safety to proceed under the construction codes, as long as review is requested when the work starts. We tarp first, then document the original materials so the permanent repair matches. Photos of the roof before damage help. Keep records of every repair; future buyers of Main Street homes value proof that the historic fabric was maintained. Our slate roof repair in Chatham follows this approach.

Chatham Borough and Chatham Township are two separate municipalities with different construction offices and different historic rules, even though they share the 07928 ZIP code and the School District of the Chathams. The Borough split from the Township when residents voted to secede on August 9, 1892, and it reincorporated as a borough on March 1, 1897. Its boundaries have stayed the same since it acquired a slice of Florham Park in 1910.

For roofing, the difference matters in three ways. First, permits. If your roof job needs a permit, because sheathing is replaced or the building is attached, multi-family or commercial, the application goes to your own municipality’s construction office. Second, historic review. The Borough’s Historic Preservation Commission covers the Main Street Historic District inside the Borough; the Township has its own approach. Third, storm response and debris. Each municipality runs its own public works and tree crews, so after storms like Sandy, which cost the Borough an estimated $680,841, schedules and rules for curbside debris differ.

How to tell which you are in: check your property tax bill or deed, which names the municipality, or look up your address on the Morris County tax records. Mailing addresses alone are unreliable because both use Chatham. The houses differ too. The Borough is compact, older and mostly built before World War II, while the Township has more post-war homes on larger lots near the Great Swamp. A good roofer working here should ask which Chatham you live in before quoting anything that touches permits.

The most common leak we find in Chatham Borough is at the joint between an original roof and a newer addition, dormer or enclosed porch. Because the borough was largely built out before World War II and its population has stayed around 9,000 to 9,500 since 1960, families here expand rather than move, and most older houses have been added to at least once.

Leaks at these joints have predictable causes. The new roof was tied into the old one without lifting the old roofing far enough, so water runs behind the new flashing. Step flashing was skipped and the joint was sealed with caulk, which fails within a few years. The addition’s roof sits lower than the old eave, creating a valley that catches leaves and ice. Or the old and new roofs move differently with the seasons, opening any rigid seal.

A proper repair opens the roofing on both sides of the joint, installs step flashing woven with each course of shingles or slate, adds counter flashing on any wall or chimney, and lays ice and water shield under the transition. Where a low-slope addition meets a pitched main roof, the low-slope section needs membrane, not shingles, flashed up under the main roof’s courses. On slate main roofs, the transition is worked in copper and the slate re-laid over it.

If you are planning an addition, ask your architect and roofer to detail this joint in advance. If you already have one that leaks, a targeted repair usually costs far less than a new roof. Learn more on our roof leak repair page.

Falling trees cause most serious roof damage in Chatham Borough, and handling the first days carefully makes the repair and insurance claim much simpler. The borough’s mature canopy is part of its charm, but Sandy’s toll of roughly $600,000 in damage to borough trees, the October 2011 snowstorm that broke branches while leaves were still on, and Irene’s tree that landed between two houses show how often trees fail here.

Step one is safety. Stay away from any tree touching wires and report it to the utility. Step two is documentation: photograph the tree, its stump or origin, the roof, gutters and interior damage from safe ground. Step three is protection: send an emergency request through our contact page, and once the tree is off, we tarp the opening to keep rain out of attics and ceilings.

Step four is the claim. Damage to your house from a tree, including a neighbour’s tree, is normally covered by your own homeowners policy; tree removal coverage may have limits. Keep every receipt. Step five is the repair. We inspect the deck and rafters for structural damage; if sheathing or framing needs replacing, a permit is required from the Borough’s construction office. Damaged slate can usually be repaired around the impact with matched stone, and copper gutters and valleys can be rebuilt section by section.

Prevention helps: ask an arborist to check large trees overhanging your roof, especially oaks on the streets off Fairmount Avenue and near the Passaic in Stanley. Our storm damage roof repair report gives your adjuster an itemized scope.

Homes in Stanley and along River Road sit beside the Passaic River on Chatham Borough’s eastern edge, and their roofs deal with damp air, shade and heavy leaf fall more than most of the town. Stanley was the borough’s industrial section, named by George Shepard Page, whose mills stood where Stanley Park is now. Today its streets hold late nineteenth and early twentieth-century homes, including the James Perrin House at 70 River Road and a vintage stucco house at 63 River Road.

The river shapes roof care in several ways. Fog and humidity keep north-facing slopes damp, so moss and lichen grow on shingles, slate and cedar. Moss holds water, lifts shingle edges and speeds rot in cedar. Heavy leaf fall clogs gutters, which then overflow onto fascia and soffits, rotting the wood behind them. During floods like Ida, when the Passaic reached about 8.1 feet at Chatham, ground and basements stay wet for days, and attic ventilation becomes even more important to keep moisture from building up under the roof deck.

Good practice here: clean gutters at least twice each autumn, trim branches back from the roof, treat moss gently without pressure washing, and check attic ventilation at the soffits and ridge. Replace rotted fascia before installing new gutters. For cedar roofs, keep the surface clean and replace split shingles individually. For flood-related questions, remember that water entering a basement from the river is a flood-policy matter, while water through the roof is a homeowners claim.
