We’ve been driving to East Hanover since 1984, long before the Route 10 corridor filled with pharmaceutical campuses and big-box retail. Our crews know the difference between a 1968 raised-ranch off Eagle Rock Avenue and a 1974 bi-level near Lurker Park. That matters because East Hanover’s housing stock isn’t generic, and neither are its roof failures. The split-levels and raised-ranches built during the township’s 1960s-1970s suburban expansion are now fifty-plus years old, many on their second or third roof, with original low-slope garage sections that were never built to handle Morris County’s freeze-thaw punishment.
When your ceiling stains appear every February or your roofer finds soft decking at the eave line, you want someone who has seen that exact failure pattern before. We have. Hundreds of times, on streets from North Road to Mount Pleasant Avenue.
Why Ridgeline Roofing Co. Is East Hanover’s Preferred Roof Replacement & Installation Company
East Hanover homeowners call us back because we show up when we say we will, and because our 90-Day Done Right Promise means exactly what it says: if something isn’t right, we make it right with no paperwork, no arguing, no runaround. After forty-two years in this business, we know that trust is built one honest course at a time.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos taken from your actual roof - not a scary speech in the driveway. You see what we see: the delaminated OSB at the garage eave, the valley where two shingle layers meet three, the nail pops along the shallow-pitch transition that every East Hanover split-level seems to develop by year fifteen.
A live person answers our phones 24 hours a day, seven days a week. Not a callback window. Not a voicemail tree. When ice dams back meltwater into your top-floor ceiling at 2 a.m., someone who can dispatch help is on the line.
We hire local crews and train apprentices into journeymen. We’re not storm chasers in trucks from three states away. When you need us next spring, or in five years, or in fifteen, we’ll still be here. That’s the difference between a company named for the ridge - the line where a roof proves itself - and one that disappears before the check clears.
Our Roof Replacement & Installation Services in East Hanover
Full Roof Replacement
Most East Hanover full replacements we perform involve tear-offs of multiple shingle layers on 1960s-1970s split-levels, with deteriorated decking at valley transitions and low-slope garage sections. The original plank or OSB decking on these homes often cannot support another overlay, and Morris County building code now requires full removal once two layers are in place. We strip to bare sheathing, replace compromised decking with proper plywood, and install ice-and-water shield at all eaves and valleys - the protection your original builder skipped because it wasn’t required in 1969. Our Roof Replacement & Installation team handles the full scope, from permit pull to final inspection.
Asphalt Shingles
Architectural shingles are the right choice for most East Hanover homes - they handle the 20-30+ inches of seasonal snowfall and 30+ freeze-thaw cycles that inland Morris County delivers each winter. We install GAF Timberline HDZ, CertainTeed Landmark, and Owens Corning Duration lines, matching color and exposure to existing siding and trim. On split-levels with complex multi-plane roof systems, shingle layout at valleys and dormers demands experienced layout; our crews have replaced roofs on Eagle Rock Avenue, Ridgedale Avenue, and throughout the residential neighborhoods east of Route 10.
Flat Roofing
East Hanover’s significant commercial and pharmaceutical footprint along Route 10 creates steady demand for large-format flat and low-slope membrane work - TPO, EPDM, and modified bitumen - that distinguishes this township from purely residential neighbors. We install these systems on commercial buildings, medical offices, and the low-slope residential sections that plague 1960s split-levels. That garage roof leaking at 2:12 pitch? It needs membrane, not shingles, and it needs proper insulation to stop the ice dam cycle that ruins your ceiling every March.
New Construction
New builds in East Hanover are less common than re-roofing, but we work with local builders on additions, teardowns, and infill projects. We specify proper attic ventilation and insulation from day one - the detail that prevents the ice dam problems we spend so much time fixing on older homes.

Trusted Brands We Service in East Hanover
We are authorized installers for GAF, CertainTeed, and Owens Corning - three manufacturers whose products we stock for fast turnaround on East Hanover jobs. No substitutions, no “equivalent” materials you didn’t approve. The shingles we specify are the shingles on your roof, with full manufacturer warranty registration handled by our office. For flat and low-slope work, we source TPO and EPDM membranes from the same supply chain, so a garage roof replacement doesn’t wait three weeks for material while your ceiling buckles.
Common Roof Replacement & Installation Problems We See in East Hanover Homes
- Multiple shingle layers and deteriorated decking at valley transitions. Tear-offs on 1960s split-levels routinely reveal two or three layers of shingles over original plank or early OSB decking that has absorbed decades of valley runoff. The decking is often soft or delaminated where planes intersect, turning a simple re-roof into partial sheathing replacement.
- Ice dams on low-pitch garage roofs without ice-and-water shield. The shallow 2:12 or less sections over attached garages were built before code required peel-and-stick membrane at eaves. Repeated freeze-thaw cycles lift shingles, meltwater backs up, and interior ceiling stains appear every late winter. By the time we inspect, the decking at the eave line is typically compromised.
- Original plank decking rotted at eave lines on raised-ranch homes. Decades of unsealed exposure at the roof edge, combined with gutter overflow and splash-back, destroys the bottom edge of plank decking. We replace with plywood and extend ice-and-water shield well past the interior wall line.
- Insufficient attic ventilation trapping moisture and heat. East Hanover’s 1960s-1970s homes were built with minimal or blocked soffit vents and no ridge ventilation. Hot, moist attic air melts roof snow from below; the meltwater refreezes at the cold eave, and the ice dam cycle begins again. We specify balanced intake and exhaust ventilation on every full replacement.

FAQs - Roof Replacement & Installation in East Hanover
Schedule a full tear-off of that section and replace it with a TPO or EPDM membrane system, not shingles, plus proper insulation and ice-and-water shield at the transition to the main roof. The original 2:12 or less pitch was never suitable for shingles, and without membrane protection, freeze-thaw damage will continue every winter. We recently replaced the roof on a raised-ranch on Ridgedale Avenue where the low-slope section over the attached garage had been leaking for years. Our crew found the original OSB decking was delaminated at the eave line from repeated freeze-thaw cycles. We installed new plywood decking, a full ice-and-water shield, and GAF Timberline shingles to match the main roof. Call (844) 563-1816 - we’ll inspect it at no charge and show you photos of what we find.
Morris County building code permits a maximum of two shingle layers; any roof with two existing layers requires complete tear-off before new installation. Most East Hanover split-levels we inspect from the 1960s-1970s already have two layers, sometimes three if a previous owner ignored code. We verify layer count during our free inspection and quote tear-off and decking replacement as needed. Call (844) 563-1816 to schedule - estimates are free.
Yes, we install standing-seam and metal shingle systems on East Hanover homes, though asphalt architectural shingles remain more common for this housing stock due to cost and neighborhood consistency. Metal performs well on steep-pitch sections but requires special detailing at the low-slope transitions that split-levels present. We’ll assess your specific roof geometry and recommend what makes sense - no upsell, just honest guidance. Call (844) 563-1816 to discuss options.
No - Ridgeline Roofing Co. focuses exclusively on roofing, gutters, and emergency storm response. We do not install or repair garage doors. If your garage door needs replacement, we can refer you to a trusted local specialist we’ve worked alongside for years. For the roof above that garage, though - the low-slope section that’s probably leaking - that’s exactly what we handle. Call (844) 563-1816 for the roofing inspection.
We primarily install GAF Timberline HDZ, CertainTeed Landmark, and Owens Corning Duration architectural shingles - all with full manufacturer warranty and our 90-Day Done Right Promise backing the workmanship. We do not substitute brands without your written approval, and we register your warranty directly with the manufacturer so there’s no paperwork for you to track. Call (844) 563-1816 to see sample boards and discuss color matching with your East Hanover home’s siding and trim.
