Fast, Reliable Roof Replacement & Installation Across Jericho
A full roof replacement on a typical Jericho Colonial runs $14,500-$28,000 depending on square footage and material choice, and most jobs are completed in 2-4 business days once materials arrive. Our crews are on Jericho roads daily, and we answer live at (866) 756-1978 every hour of every day, including the middle of a nor’easter.
We’ve been working on Jericho roofs since the mid-1980s, back when many of these center-hall Colonials were getting their first replacement cycle. We know the difference between a straightforward ranch in Hicksville and the multi-gable, multi-valley puzzle that a Jericho split-level presents. That familiarity matters when you’re estimating labor hours, ordering valley flashing, and planning how to stage materials on a half-acre wooded lot with a mature oak canopy overhead. Our Roof Replacement & Installation team doesn’t guess at Jericho jobs. We’ve done enough of them to know where the ice dams form, which slopes stay shaded, and how to price the work honestly from the start.

Our Roof Replacement & Installation Services in Jericho
Full Roof Replacement
Jericho’s housing stock is hitting its second or third full replacement cycle, and the 1960s-70s Colonials and split-levels here demand more than a tear-off and reshingling. The intersecting valleys and step-flashed dormers that give these homes their character are also textbook ice-dam formation zones during Long Island’s freeze-thaw winters. We strip to the deck, inspect for rot in the valley troughs, and install full ice-and-water shield extending 24 inches past the warm-wall line per NY State code. On a typical Jericho Colonial, you’re looking at 28-35 squares of roofing with 8-12 valleys. Labor runs longer here than on a simpler ranch. We price that honestly upfront.
New Construction
New builds in Jericho are rare compared to replacement work, but when they happen - additions, teardowns on Cantiague Lane or Jericho Turnpike - we spec from the rafters up. We coordinate with local framers and building inspectors who know Nassau County’s amended codes, and we install proper ridge venting and intake ventilation from day one. A new roof built right the first time avoids the callbacks that plague shortcut jobs.
Asphalt Shingles
Asphalt remains the practical choice for most Jericho homeowners, but not all shingles handle this microclimate equally. The north-facing slopes of Jericho’s interior-lot Colonials stay shaded year-round by 60-year-old oak and maple canopy. That shade accelerates algae and moss colonization, cutting effective shingle life by several years compared to the same product on a south-facing open lot. We specify algae-resistant granules - Owens Corning Duration Storm and CertainTeed Landmark PRO both perform well here - and we discuss zinc strip installation at the ridge for properties with particularly dense canopy cover. A standard architectural shingle replacement on a Jericho Colonial runs $14,500-$22,000.
Metal Roofing
Metal roofing is gaining ground in Jericho for homeowners who plan to stay twenty-plus years and don’t want to do this again. Standing seam aluminum or steel sheds snow load faster than asphalt, which matters when a March nor’easter dumps eighteen inches of wet snow. Metal also doesn’t host algae. Installation cost on a Jericho Colonial typically runs $28,000-$42,000, roughly double asphalt, but the lifespan is 40-70 years versus 20-25 for architectural shingles in this tree-shaded environment. We handle the specialized valley flashing and penetration details that separate a watertight metal roof from an expensive leak waiting to happen.

Trusted Brands We Service in Jericho
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Jericho jobs, we typically stock Owens Corning and CertainTeed products at our Nassau County warehouse, which means faster turnaround on standard colors and profiles. Specialty orders - Boral clay tile, for instance, or Atlas StormMaster Slate - run 2-3 weeks. We don’t substitute materials without your written approval, and we register your warranty directly with the manufacturer so there’s no question about coverage if you sell the house or need a repair ten years down the line.
Common Roof Replacement & Installation Problems We See in Jericho Homes
- Ice dams in multi-valley rooflines. Jericho’s complex Colonial and split-level rooflines create interior valleys where snow melts, refreezes, and backs up under shingles. Inadequate ice-and-water shield coverage - or worse, none at all - leads to soaked insulation and stained drywall. NY State code mandates 24 inches past the warm-wall line; we see plenty of older Jericho roofs that never met this spec.
- Algae and moss on shaded north-facing slopes. The mature canopy on half-acre Jericho lots keeps north slopes damp and cool, ideal conditions for Gloeocapsa magma colonization. Black streaks aren’t just cosmetic; algae feeds on limestone filler in shingles and accelerates granule loss. We address this with algae-resistant specifications or zinc strips.
- Valley flashing failure from improper step-flashing. The multiple dormers and intersecting roof planes on Jericho’s 1960s-70s homes require precise step-flashing and woven or closed-cut valley methods. Shortcut valley liners or inadequate metal gauge lead to leaks that show up as water spots on vaulted ceilings - often the first sign a homeowner notices.
- Undersized or blocked ventilation. Original Jericho construction often paired minimal soffit venting with inadequate ridge exhaust. Summer attic temperatures push 140°F, baking shingles from below and voiding manufacturer warranties that require proper airflow. We calculate net free area and install balanced intake and exhaust on every full replacement.
Pricing for Roof Replacement & Installation in Jericho, NY
Here is what we are seeing for Jericho’s market in 2025-2026. These are installed, permitted, and warranted prices for typical center-hall Colonials and split-levels on half-acre lots:
- Architectural asphalt shingle replacement: $14,500-$22,000
- Premium designer asphalt shingle replacement: $22,000-$28,000
- Standing seam metal roof: $28,000-$42,000
- Flat/low-slope membrane (EPDM/TPO): $8,500-$15,000
- Tile or synthetic slate: $35,000-$55,000+
What moves you within these ranges? Roof complexity is the big one. A Jericho Colonial with four gables, two dormers, and a screened porch roof has three times the flashing detail of a simple hip roof. Material choice matters - Owens Corning Duration Storm costs more than baseline Duration, but the algae resistance pays back in this tree canopy. Deck repair adds $3-$8 per square foot when we find rot in valley troughs or around chimneys. We inspect and quote all of this before you sign. The number on the estimate is the number on the invoice. Call (866) 756-1978 for a free, no-pressure estimate - we will walk your roof, take photos, and explain what we find.

FAQs - Roof Replacement & Installation in Jericho
Yes. The mature oak and maple canopy on Jericho’s half-acre lots shades north-facing slopes year-round, keeping them damp and cool enough to accelerate algae and moss growth. That colonization feeds on shingle granules and can cut effective service life by 3-5 years compared to the same shingles on an open, south-facing lot. We specify algae-resistant products and often recommend zinc strips at the ridge for heavily shaded properties. Call (866) 756-1978 and we’ll assess your specific tree cover and slope orientation.
Jericho’s dense concentration of 1960s-70s center-hall Colonials and split-levels features far more complex multi-gable, multi-valley rooflines than the simpler post-war ranches in adjacent Hicksville or Westbury. Those intersecting valleys are natural collection points for meltwater that refreezes during Long Island’s rapid freeze-thaw cycles, and NY State’s 2020 Residential Code mandates ice-and-water shield extending 24 inches inside the warm-wall line on every permit-pulled job. We treat this as non-negotiable on every Jericho replacement, not an upsell.
We do. Jericho’s typical Colonial has 8-12 valleys where roof planes intersect, each requiring either woven or closed-cut valley methods with 26-gauge pre-painted steel or copper in high-exposure areas. Standard valley liner won’t survive the thermal cycling and debris load here. We recently replaced the roof on a classic Jericho Colonial on Cedar Swamp Road, where the north-facing valley system had failed from repeated ice-damming. We installed Owens Corning Duration Storm shingles with algae-resistant granules and a full ice-and-water shield extending 24 inches past the warm-wall line, addressing both the ice-dam history and the algae colonization from the property’s mature oak canopy.
Most Jericho Colonials take 2-3 days for tear-off and installation, plus a half-day for final inspection and cleanup. Complex rooflines with multiple dormers and valleys add a day. Material delivery typically takes 3-5 business days from contract signing, though Owens Corning and CertainTeed stock colors often arrive faster from our Nassau warehouse. We don’t rush the flashing details to hit an artificial deadline. Done right - and if it’s not, we make it right.
Sometimes, but we rarely recommend it for Jericho’s split-levels. Those complex rooflines already challenge ventilation and drainage; adding a second roof layer traps heat and moisture, accelerates deck rot, and voids most manufacturer warranties. We prefer full tear-off so we can inspect the deck, upgrade ventilation to current code, and install proper underlayment. If your deck is sound and local code allows overlay, we’ll discuss it - but we’ll also tell you why we think it’s a shortcut. Call (866) 756-1978 for an honest assessment of your specific roof.
