We’ve worked on Chatham roofs since the mid-1980s, back when Pete Navarro was climbing steep-pitched Tudors on Fairview Avenue and Hillside Avenue with a hammer and a bundle of copper flashing. We know the borough’s 07928 ZIP from the train station to the Watchung border, and we understand what fails here: ice dams at dormer valleys, rotted skip sheathing under century-old slate, moss colonies on north slopes shaded by the borough’s canopy of mature oaks and maples. This isn’t generic suburban roofing. Chatham’s housing stock - dense with 1920s-1940s Tudor Revival and Colonial Revival homes - demands a crew that recognizes skip sheathing, knows how to re-deck without damaging plaster ceilings below, and prices the full scope honestly from the first walkthrough.
Our Roof Repair team doesn’t chase storms from out of state. We’re the company that trains apprentices into journeymen and plans to be pricing Chatham roofs thirty years from now. That matters when you’re sitting in a 1930s dining room with a bucket under a dormer leak and you need someone who will still answer the phone if the patch doesn’t hold.
Why Ridgeline Roofing Co. Is Chatham’s Preferred Roof Repair Company
Homeowners in Chatham call us because we’ve been here long enough to become predictable. Founded in 1984, Ridgeline Roofing Co. has stood behind local roofs for over 42 years - not chasing storms, but building a crew of background-checked, uniformed technicians who document every inspection with photos from your actual roof. The same standard we’d hold for work done in our own mother’s home.
Our reputation in Chatham is built on one principle: a square deal. The price we quote is the price you pay. No change-order games, no “we found something unexpected” halfway through the job. We price for the skip sheathing replacement upfront because we’ve seen enough Chatham attics to know what’s likely hiding under that slate. Our 90-Day Done Right Promise is written, not verbal - if it’s not right, we come back and make it right. No paperwork to file, no arguing, no runaround.
Response time matters when water’s hitting your plaster. We typically reach Chatham Borough within 45 minutes during business hours, and our phones are staffed by a live person 24 hours a day, seven days a week - including the middle of a storm. We’ve pulled into driveways on Southern Boulevard at midnight after homeowners called about ice-dam blowback, and we’ve traced valley leaks on Ridgedale Avenue while the homeowner’s morning coffee was still hot.
We also serve Chatham homeowners who remember the last contractor who let them down. The one who quoted low, discovered rotted sheathing, and disappeared for three weeks mid-job. We don’t operate that way. Our estimates include contingency pricing for likely structural issues, and our crews carry the plywood, ice-and-water shield, and copper flashing to complete most repairs in one trip.
Our Roof Repair Services in Chatham
Valley Repair
Chatham’s steep-pitched Tudors and Colonials create complex valley geometry where multiple roof planes intersect, and these valleys take the brunt of snow load funneled down from the Watchung ridgeline. Ice dams form here first, lifting shingles and forcing water uphill into the structure. A typical valley repair in Chatham runs $850-$1,800, including removal of damaged materials, installation of GAF WeatherWatch ice-and-water shield, and re-flashing with 16-ounce copper. On older homes, we often find the original valley tin has corroded through or the skip sheathing beneath has rotted at the intersection - we price for this possibility so you’re not staring at a change order at noon on day two.

Flashing Repair
Chimney and dormer flashing on Chatham’s pre-WWII homes was often installed with galvanized steel or lead that has fatigued after ninety years of thermal cycling. We repair flashing without pushing full replacement unless the roof’s at end of life. A chimney flashing repair on a Colonial Revival on Hillside Avenue, for example, typically costs $650-$1,400: we cut back the surrounding shingles, install new step flashing and counterflashing, and seal with high-temperature membrane. We can complete most flashing repairs in one day, preserving the surrounding roofing and the homeowner’s schedule.

Leak Repair
Active leaks in Chatham cluster around dormer valleys, skylight curbs, and chimney shoulders - all places where ice dams and wind-driven rain exploit gaps in aging systems. Our leak repair process starts with interior tracing to locate the water path, then exterior investigation with photo documentation. Most Chatham leak repairs fall between $450-$1,200 for straightforward shingle and sealant work, or $1,500-$2,800 when deck repair and interior protection are needed. We recently repaired a valley leak on a 1930s Tudor on Fairview Avenue. The original slate had partially failed, and when we exposed the valley intersection, we found rotted skip sheathing. Our crew replaced the damaged boards with new 3/4-inch CDX plywood, installed GAF WeatherWatch ice-and-water shield, and re-flashed the valley with 16-oz copper, all in one trip so the homeowner didn’t have to manage a multi-day disruption.

Flat Roof Patch
Chatham’s flat roofs appear on additions, porches, and detached workshops - often EPDM rubber or modified bitumen that has aged past warranty. Patching runs $400-$950 for localized membrane repair, or $1,800-$3,200 for full section replacement with proper taper and drainage correction. We also handle commercial-type flat roofing on residential outbuildings, using Atlas and Tamko systems rated for the heavy debris load from surrounding oak canopy.

Trusted Brands We Service in Chatham
We’re authorized installers for seven manufacturer lines - GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - and we stock repair-compatible materials for all of them. For Chatham’s historic homes, we frequently specify GAF Camelot II synthetic slate or CertainTeed Grand Manor architectural shingles that replicate the dimensional shadow lines of original slate without the structural load. Our trucks carry Atlas StormMaster Slate for repairs where impact resistance matters, and we source Tamko Heritage Vintage for color-matched patching on older installations. Because we keep common Chatham profiles in stock, most brand-specific repairs don’t wait on a distributor run to Summit or Short Hills.
Common Roof Repair Problems We See in Chatham Homes
- Ice dam infiltration at dormer valleys and skylights. Chatham sits in a low valley flanked by the Watchung ridgeline, which traps cold air and funnels nor’easter moisture into above-average snowfall. Steep pitches shed snow fast, but complex valley geometry creates backup points where ice dams force water under shingles. We see this every February on homes near the ridgeline.
- Granule loss and moss colonization on north-facing slopes. The borough’s mature oak and maple canopy shades significant roof area, accelerating shingle granule loss from debris impact and fostering moss growth that retains moisture. Targeted shingle replacement with algae-resistant Atlas or GAF products addresses this without full re-roofing.
- Hidden skip sheathing decay under original slate. Many of Chatham’s older Tudors still have rough-sawn skip sheathing - spaced boards rather than solid plywood - that was never meant to last a century. When tear-off reveals undersized or rotted boards at valley intersections, the repair scope expands to full re-decking. Local roofers who don’t price for this upfront routinely face expensive change orders mid-job. We don’t.
- Failed vent boots and plumbing stack seals. Original lead or rubber vent boots on pre-WWII homes have cracked from UV exposure, creating straight-line leaks that show up as ceiling stains below bathrooms. A $350-$600 vent boot replacement solves this - if the roofer recognizes the symptom and doesn’t sell a full replacement.

FAQs - Roof Repair in Chatham
We recommend exposing the valley to inspect the sheathing beneath, replacing any rotted skip sheathing with 3/4-inch CDX plywood, installing ice-and-water shield, and re-flashing with copper. This solves both the immediate leak and the underlying structure that caused it. Most dormer valley repairs in Chatham run $1,200-$2,200 and finish in one day. Call (844) 563-1816 for a free inspection - we’ll photograph what we find and talk through the scope before any work begins.
Yes, skip sheathing repair and full re-decking is standard work for us on Chatham’s pre-WWII housing stock. We encounter it on roughly half the slate tear-offs we do in the borough, and we price for the likelihood in our initial estimate. If your sheathing is sound, you pay the base price. If it needs replacement, we’ve already built the contingency into your quote - no mid-job surprises. Our crew carries plywood, fasteners, and underlayment on every Chatham call so we can proceed without a return trip.
Yes, localized flashing repair is often the right choice on Chatham’s older homes where the roof field still has serviceable life. We cut back shingles around the chimney, install new step and counterflashing, and integrate with the existing roofing. Most chimney flashing repairs run $650-$1,400 and preserve five to fifteen years of remaining roof life. We’ll tell you honestly if the surrounding shingles are too brittle to disturb - in that case, we’d recommend timing the flashing work with your next replacement.
Yes, we repair residential flat roofs including outbuildings, porches, and additions. We work with EPDM, modified bitumen, and TPO systems, and we can patch localized leaks or replace sections that have aged out. Most workshop flat roof repairs in Chatham run $400-$1,200 depending on membrane type and whether the substrate needs replacement. Call (844) 563-1816 - we’ll assess whether a patch will hold or if the roof has reached replacement territory.
The first step is a photo-documented inspection of the north-facing slope and adjacent valleys, with interior ceiling checks below. Moss retains moisture that accelerates shingle deterioration and creates capillary paths for water entry. We remove moss mechanically (never pressure-wash, which voids warranties), assess shingle condition, and replace any degraded tabs. If we find active leaks, we trace them to source and repair. Moss-related inspections in Chatham are $89 during our seasonal tune-up special, and the full remediation typically runs $600-$1,800. Call (844) 563-1816 to schedule - early fall is ideal, before the freeze-thaw cycles begin.
