Fast, Reliable Roof Replacement & Installation Across Hillside
A full roof replacement on a typical Hillside Cape Cod or two-family home runs between $8,500 and $18,000 depending on layers to remove, sheathing condition, and whether flat sections need rebuilding. Most Hillside jobs our Roof Replacement & Installation crew takes on are completed in two to four days, with same-day emergency tarping available when nor’easters tear through northern Union County. Call (844) 563-1816 and a live person will answer, 24 hours a day.
We’ve been climbing Hillside roofs since 1984. We know the narrow lots off Liberty Avenue, the shared rooflines on Dewitt Terrace, and the way winter wind funnels down Stuyvesant Avenue to rip shingles off low-pitched dormers. Hillside’s housing stock is old, dense, and unforgiving. That is not a problem for us. It is the work we have built our name on.
Why Ridgeline Roofing Co. Is Hillside’s Preferred Roof Replacement & Installation Company
Forty-two years in business means we have replaced roofs on Hillside homes three times over. Homeowners here do not want a salesman in a truck with out-of-state plates. They want Pete Navarro’s crew, the same background-checked, uniformed technicians who documented the last job with photos from the actual roof, not the driveway.
Our 90-Day Done Right Promise is written and simple: if it is not right, we come back and make it right. No paperwork to file, no argument, no runaround. That promise has held since 1984, and it still does on every Hillside job we sign.
Phones are staffed by a live person around the clock. Not a voicemail tree. Not a callback window. When water is coming through your ceiling at 2 a.m. after a February ice dam, someone answers for Emergency & Storm Damage in Hillside.
We hire local crews and train apprentices into journeymen. We plan to be here in thirty years, not thirty days. That is the difference between a contractor and a storm chaser.
Our Roof Replacement & Installation Services in Hillside
Full Roof Replacement
Most Hillside homes need full tear-offs, not overlays. New Jersey code prohibits more than two layers of roofing material, and with 80-90% of Hillside’s housing built between 1920 and 1955, we routinely find three layers of asphalt shingles over original 1×6 board sheathing. The sheathing is often rotted where decades of lay-overs trapped moisture. We tear off to the deck, replace failed sections with 5/8″ CDX plywood, and install a proper underlayment system. On a two-family home on Liberty Avenue, we found a legacy rolled-roof section over a north-facing rear kitchen addition that had been patched four times. The deck was spongy, no visible leak inside yet, and we had to tear off three layers of asphalt over original board sheathing, replacing rotted sections with 5/8″ CDX plywood and installing GAF Timberline HDZ shingles to meet NJ code. Full replacement in Hillside typically runs $10,000-$18,000 for a standard Cape Cod or colonial, including sheathing repair.
Asphalt Shingles
Asphalt shingles remain the practical choice for Hillside’s steep-slope roofs. We are authorized installers of GAF, CertainTeed, and Owens Corning, and we do not substitute materials without your written approval. For Hillside’s freeze-thaw cycle, we specify architectural shingles with 130-mph wind ratings, full ice-and-water shield at eaves and valleys, and matching Gutters & Accessories - Hillside systems. The low-pitched rear dormers common on 1920s-1950s Cape Cods are especially vulnerable; standard three-tab shingles often fail prematurely here, so we typically upgrade to dimensional products. A typical asphalt re-roof on a Hillside Cape Cod runs $8,500-$14,000 including tear-off.
Flat Roofing
Hillside’s two-family homes almost always have flat or near-flat sections over rear kitchen additions. These face north, rarely dry out, and local roofers consistently find them patched three or four times with mismatched materials. The underlying wood deck is spongy long before any visible interior leak appears. We replace these with modified bitumen or TPO systems, depending on slope and drainage, and we always inspect the surrounding sheathing because rot spreads sideways in Hillside’s original board decks. Flat section rebuilds typically add $3,000-$6,500 to a full replacement.
New Construction & Additions
New builds are rare in Hillside, but dormer additions and second-story pop-ups are not. We match existing rooflines on tight lots where scaffolding clears the neighbor’s fence by inches. Proper valley flashing and ventilation are critical; Hillside’s older homes were not built for modern insulation levels, and new work must integrate without trapping moisture in original board sheathing.

Common Roof Replacement & Installation Problems We See in Hillside Homes
- Hidden rot under original board sheathing. Decades of lay-overs on 1920s-1950s Cape Cods trap moisture against 1×6 or 1×8 planks. We find punky wood on nearly every full tear-off in Hillside, especially within three feet of shared walls where ventilation was never addressed.
- Spongy flat-roof decks over north-facing kitchen additions. These sections never see sun, patch jobs accumulate, and the deck fails structurally before drywall stains appear. By the time you see a leak inside, the framing is often involved.
- Ice dams at low-pitched dormer transitions. Pre-1960 Hillside homes lack adequate attic insulation. Warm air melts snow; refreezing at the cold dormer edge forces water uphill, under shingles, and into wall cavities. In Hillside, nearly every roofing job involves low-pitched rear dormers on 1920s-1950s Cape Cods where freeze-thaw cycles cause ice dams that wick water under original 1×6 board sheathing, a failure mode almost unheard of in towns with newer plywood decks.
- Shared roofline complications on two-family homes. Hillside’s narrow lots mean zero clearance between buildings. Replacing one side without damaging the neighbor’s roof requires precise edge detail and often coordinated access.

FAQs - Roof Replacement & Installation in Hillside
No. New Jersey code prohibits more than two layers, and three layers indicate the original board sheathing has likely been trapping moisture for decades. We perform a full tear-off, inspect every plank, and replace deteriorated sections with plywood. Call (844) 563-1816 for a free estimate.
If it has been patched more than twice, especially on a north-facing Hillside addition, the deck is likely compromised even if you see no interior leak. We inspect with moisture meters and core samples; spongy wood requires rebuilding, not another patch. Call (844) 563-1816 to schedule an inspection.
A new roof with proper ice-and-water shield helps, but ice dams are primarily an insulation and ventilation problem. We address the roof assembly and recommend concurrent attic air-sealing and insulation upgrades. Without that, ice dams will recur on Hillside’s low-pitched dormers. Call (844) 563-1816 to discuss integrated solutions.
Yes, though it requires careful edge flashing where the roofs meet. We have done this on dozens of Hillside duplexes on narrow lots. We coordinate access to protect both properties and document the shared boundary with photos before we start. Call (844) 563-1816 to review your specific situation.
We replace only failed sections, typically 15-40% of the deck on Hillside’s older homes. Sound 1×6 plank sheathing, properly spaced, performs well when integrated with new plywood patches. Full plywood redecking is available but rarely necessary unless fire damage or extreme deterioration is present. Call (844) 563-1816 for an exact assessment.
