Fast, Reliable Roof Repair Across Jericho
Most roof repair in Jericho runs $350-$1,800 depending on the scope, and our crews can usually be on your roof the same day you call. We know the 1960s-70s Colonials and split-levels that dominate Jericho - the multi-gable rooflines, the shaded north-facing valleys under mature oak canopy, the original step flashing that’s now sixty years old. When water starts coming through the ceiling during a February nor’easter, you need someone who understands what they’re looking at, not a sales pitch.
We’ve been repairing roofs since 2016, and we’ve worked on homes from the Jericho Turnpike corridor down to the wooded lots off Cedar Swamp Road. Our Roof Repair team lives by the same standard on every job: background-checked, uniformed technicians, photo-documented inspections, and a live person answering the phone at (866) 756-1978 - day or night, weekend or holiday. If you’re in 11753 or 11853, we’ll be there when we say.

Our Roof Repair Services in Jericho
Valley Repair
Jericho’s defining roofing challenge. Those handsome multi-gable Colonials and split-levels from the 1960s and 70s create interior valleys where four, sometimes six roof planes intersect. North-facing valleys under mature oak canopy never fully dry. Ice dams form. Water backs up. The original W-ventilated valley metal corrodes. We replaced a failing valley on a 1972 Colonial on Cedar Swamp Road last winter. The original step flashing had corroded, and multiple layers of poorly applied roof cement had trapped moisture. We installed new GAF WeatherWatch ice-and-water shield 24 inches past the warm wall and a new W-ventilated valley for proper drainage. Done right - and if it’s not, we make it right.
Leak Repair
Leaks in Jericho rarely come from obvious places. They travel: from a failed vent boot on a dormer, down a rafter bay, emerging three rooms away. Our leak repair starts with systematic tracing - not guesswork. We factor in Jericho’s specific conditions: the heavy wet snow of Long Island nor’easters, the rapid freeze-thaw cycles, the way that mature tree canopy keeps north slopes damp for days after a storm. Most leak repairs in Jericho run $450-$1,200 and are completed in a single visit.
Flashing Repair
Original step flashing on Jericho’s 1960s-era homes is often galvanized steel that’s reached the end of its life. Corrosion at the wall-to-roof junctions, particularly on complex rooflines with multiple dormers, creates hidden water intrusion that can rot sheathing for years before showing inside. We remove the old, install new copper or pre-finished aluminum step flashing, and integrate it properly with the shingle course. For Jericho’s heritage homes, this is preservation, not just repair.
Flat Roof Patch
Some Jericho split-levels and additions have low-slope sections over garages or breezeways. These demand different materials - modified bitumen or TPO, not standard shingles. We stock the right membranes and can patch most flat roof sections same-day, stopping the leak before your next storm.

Common Roof Repair Problems We See in Jericho Homes
- Ice dams in shaded north-facing valleys. Jericho’s mature 60-year-old oak and maple canopy shades the north-facing roof slopes of interior-lot Colonials year-round. This accelerates algae and moss colonization on asphalt shingles and creates perfect ice-dam conditions during freeze-thaw cycles - a pattern we flag on every inspection and address with proper ice-and-water shield and ventilation.
- Corroded original step flashing on complex rooflines. The 1960s-era galvanized step flashing on Jericho’s multi-gable homes has simply reached end of life. Hidden behind siding and shingles, it fails slowly, rotting sheathing and framing while showing only faint water stains inside.
- Layered “repair” cement trapping moisture. Previous owners or handymen often applied roof cement over old shingles as a quick fix. In Jericho’s humid freeze-thaw climate, this traps moisture against the shingle substrate, accelerating decay rather than preventing it. We strip to sound decking and start clean.
- Algae and moss shortening shingle life on shaded slopes. The same canopy that makes Jericho beautiful cuts effective roof life by several years on north-facing slopes. We address this with algae-resistant shingle specifications or zinc strip installation at the ridge.
Pricing for Roof Repair in Jericho, NY
Here is what honest roof repair pricing looks like in Jericho’s market in 2025:
| Repair Type | Typical Range in Jericho |
|---|---|
| Shingle replacement (small area, up to 2 sq) | $350-$650 |

Jericho’s complex rooflines mean longer labor hours per square than simpler ranches in adjacent Hicksville or Westbury. Multiple gables, hipped sections, dormers, and interior valleys require more flashing material and more time. The price we quote accounts for this honestly - no lowball to get in the door, no surprises after.
We offer $50 off any repair over $250, a free second opinion on any written estimate, and a permanent 5% senior and veteran discount. Estimates are free. Call (866) 756-1978.

FAQs - Roof Repair in Jericho
It’s the combination of three factors: complex multi-valley rooflines that slow drainage, mature oak and maple canopy that keeps those slopes shaded and damp, and Long Island’s nor’easter-driven freeze-thaw cycles. NY State’s 2020 Residential Code requires ice-and-water shield extending 24 inches inside the warm-wall line - a spec we honor on every permit-pulled job in Jericho. Proper valley flashing and ventilation are the fix, not just more roof cement. Call (866) 756-1978 for an inspection - estimates are free.
Yes, often you can - if the surrounding shingles are in reasonable condition and the decking beneath is sound. We open the valley, inspect the sheathing, install proper ice-and-water shield to code, and lay new valley metal and shingles. A partial valley repair typically runs $800-$1,400 in Jericho, versus $12,000-$25,000 for full replacement. We’ll tell you honestly which path makes sense. Call for a free evaluation.
We use GAF WeatherWatch or CertainTeed WinterGuard ice-and-water shield for the underlayment, paired with new W-ventilated valley metal. For shingle integration, we match existing - Owens Corning, IKO, Atlas, or others from our seven authorized lines. We don’t substitute. Call (866) 756-1978 to discuss what’s on your roof now.
The mature canopy that makes Jericho desirable also creates extra labor: more debris clearing, more careful ladder and staging placement, and more frequent need for algae-resistant materials on shaded slopes. Repairs on heavily wooded lots may run 10-15% higher than open-lot equivalents, but the alternative - standard shingles failing prematurely - costs far more. We factor this into every estimate upfront. No surprises.
No. Many leaks in Jericho’s 1960s-70s homes originate from localized failures: one corroded valley, one failed vent boot, one section of deteriorated step flashing. If the shingles are less than 20 years old and the decking is sound, targeted repair is often the smarter money. We document everything with photos and give you straight guidance - repair now, plan for replacement later, or replace now if the roof is truly at end of life. Call (866) 756-1978 for an honest assessment.
