Union sits at the crossroads of the Garden State Parkway and Route 22, and our crews are on local roads daily. We don’t dispatch from some regional hub three counties away.

Why Ridgeline Roofing Co. Is Union’s Preferred Roof Repair Company
We’ve been standing behind roofs in Union Township and Essex County for over 42 years. That’s not a marketing number - it’s the count from 1984, when Pete Navarro started this company with the belief that a roof should be fixed once and fixed right, and that a handshake still means something.
Our reputation here is built on showing up. Not next week. Not after three voicemail callbacks. When a nor’easter tears through Union’s nor’easter corridor and water starts dripping into your living room, you reach a live person on our line - 24 hours a day, seven days a week, including the middle of the storm. No phone trees. No “leave a message and we’ll get back to you.”
Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not a scary sales pitch in your driveway. We bring the same standard we’d hold for work done in our own mother’s home. And every repair we make is backed by our written 90-Day Done Right Promise - if it’s not right, we come back and make it right. No paperwork runaround. No arguing.
Union homeowners tend to stay put. They’ve raised families in these split-levels and Cape Cods, and they plan to stay another twenty years. They remember the last contractor who let them down. We’re built for that customer - the one who wants a square deal, not the lowest bid from a truck that won’t be in town next spring.
Our Roof Repair Services in Union
Valley Repair
Union’s signature roofing problem is the valley where a steep main roof meets a low-slope garage section - a configuration nearly universal on 1950s split-levels throughout the township. The original step flashing at this junction was often installed without counter-flashing, and sixty years of freeze-thaw cycling has left it corroded or missing entirely. We repair these valleys by stripping to the deck, installing new copper or aluminum step flashing, and running a full course of ice-and-water shield across the low-slope section. A typical valley repair on a Union split-level runs $1,200-$2,400, depending on how far the water has traveled into the sheathing.

Flashing Repair
Flashing is where most Union roofs fail, not the shingles themselves. The combination of original galvanized steel that’s reached the end of its life, layered additions that created new junctions without proper counter-flashing, and the township’s heavy wet snow loads means water finds the path of least resistance at every transition. We replace corroded step flashing, install missing counter-flashing where original construction skipped it, and seal chimney and vent penetrations with proper saddles and cricket diverters. Flashing repairs in Union generally fall between $450-$1,100 for localized work, or $1,800-$3,200 when multiple junctions across an addition need attention.

Leak Repair
When water appears on your ceiling, the source is rarely directly above the stain. On Union’s multi-plane split-level roofs, water can travel ten feet along the deck before finding a seam. Our leak repair process starts with a full photo-documented inspection to trace the entry point, then addresses both the symptom and the cause. We see chronic leaks in the finished space below garage roofs on Vauxhall Road, on dormer cheeks in Connecticut Farms, and at addition valleys throughout the township. Standard leak repairs range from $350-$850; if the OSB deck has rotted through, expect $1,400-$2,600 to replace decking and secure the source.

Flat Roof Patch
Those low-slope garage sections on Union’s split-levels - typically 2/12 to 3/12 pitch - cannot be properly protected with standard shingles alone. We patch these areas with modified bitumen membranes or self-adhering ice-and-water shield systems from GAF and CertainTeed, materials designed for standing water and slow drainage. A flat roof patch on a Union garage section runs $800-$1,600 depending on square footage and whether the original sheathing needs replacement.

Trusted Brands We Service in Union
We don’t substitute materials without telling you. Ridgeline is an authorized installer for seven manufacturer lines, and for Union’s climate we most often specify GAF Timberline HDZ shingles for their LayerLock technology and StainGuard protection against the algae that thrives in our humid summers, CertainTeed Landmark PRO for its dual-layer construction and excellent freeze-thaw durability, and Tamko Heritage shingles for homeowners who want a heavier laminate at a straightforward price. We stock common repair components locally, so most Union jobs don’t wait on special orders. The brand on your estimate is the brand on your roof - no bait-and-switch, no “equivalent” substitutions.
Common Roof Repair Problems We See in Union Homes
- Corroded step flashing at garage-to-main-roof transitions. The signature failure of Union’s 1950s split-levels. Original galvanized flashing rusts through after 60-80 years, and the absence of counter-flashing in original construction leaves the joint exposed. We repaired a 1956 split-level on Vauxhall Road where this exact failure had rotted the OSB deck and damaged finished drywall below. We replaced the corroded flashing with new copper step flashing and added a full course of GAF ice-and-water shield across the low-slope section, securing the failed valley and preventing future ice-dam backup.
- Shingle cracking on low-slope dormer sections of Cape Cods. Union’s rapid freeze-thaw cycling attacks the thinner shingles used on dormers and shed roofs, which heat and cool faster than the main roof. Standard 3-tab shingles that still appear on older installations are particularly vulnerable.
- Layered addition valleys without proper counter-flashing. Many Union properties have had garages, family rooms, or second-story additions built over original construction, multiplying the number of flashing junctions. Each new valley is only as good as the flashing beneath it, and we’ve found three layers of roofing with no counter-flashing at the original junction.
- Ice-dam damage at shallow overhangs. Union’s mid-century homes were built with minimal eave overhangs, giving ice dams nowhere to go but back under the shingles. The low-slope sections common to split-levels are the first to fail, but water often travels into insulated walls before it’s visible inside.

What moves a job toward the higher end: multiple layers of old roofing to remove, rotted OSB or board sheathing that needs replacement, access challenges on steep pitches, and the extent of interior damage that must be traced and sealed. What keeps costs down: catching the problem before water reaches the deck, which is why we offer our $89 Seasonal Tune-Up - a full inspection with photos, scheduled before the winter freeze-thaw season begins.

FAQs - Roof Repair in Union
The leak returns because the source is almost certainly the step flashing where your low-slope garage roof meets the steep main roof, not the shingles themselves. Original construction on Union’s split-levels typically omitted counter-flashing at this junction, and sixty years of exposure has corroded what remains. Patching the shingles above the leak only redirects water to the next weak point. We fix it by stripping to the deck, installing new copper step flashing with proper counter-flashing, and protecting the full low-slope section with ice-and-water shield. Call (844) 563-1816 for a free inspection - we’ll show you exactly where the water is entering.
If your roof is under fifteen years old and the shingles are otherwise sound, localized flashing repair is the right call and typically costs $450-$1,100. If the roof is past twenty-five years, has multiple leak points, or shows widespread shingle cracking from Union’s freeze-thaw cycling, replacement becomes more economical than chasing individual failures. We’ll tell you straight which path makes sense after our photo-documented inspection. Our Free Second Opinion on Any Written Estimate gives you that clarity with no obligation.
No - standard asphalt shingles are not rated for pitches below 4/12 and will leak again within a season. Union’s 2/12 and 3/12 garage sections require modified bitumen membrane or self-adhering ice-and-water shield systems designed for standing water and slow drainage. We install these with proper integration into the main roof’s flashing system, which is the only way to stop the chronic leaks at this transition. Most garage-section repairs run $800-$1,600.
Union homes built 1945-1965 typically have 1×6 or 1×8 board sheathing, sometimes with skip sheathing gaps that require solid decking before modern shingles can be installed. Homes with 1970s additions or later renovations may have OSB. The difference matters for repair strategy: board sheathing can rot locally and be patched, while OSB fails in larger sheets and wicks water farther from the leak point. We determine what you have during our inspection and document it with photos from your attic and roof surface.
For Union’s climate - heavy wet snow, rapid freeze-thaw, and significant summer UV and humidity - we most often recommend architectural laminate shingles with a 130-mph wind rating and algae-resistant granules. GAF Timberline HDZ and CertainTeed Landmark PRO both perform well here, with layered construction that resists the thermal cracking common on low-slope sections and StainGuard protection against the black streaks that appear on north-facing slopes by mid-summer. We’ll match the specific product to your roof’s pitch, exposure, and your preference. Call (844) 563-1816 to discuss options - estimates are free.
