A live person answers, 24/7, and we’ll get a uniformed technician to your Westbury home for a photo-documented inspection.
We’re not storm chasers. We’re the company that trains apprentices into journeymen and plans to be here in thirty years.

Why Ridgeline Roofing Co. of New York City Is Westbury’s Preferred Roof Replacement & Installation Company
Forty-two years in business means we’ve replaced roofs on Westbury homes twice over. We know which streets still carry the original 1940s-1960s Cape Cods with rafter-framed roofs and minimal attic ventilation, and which neighborhoods have already seen their first full tear-offs. That matters because Nassau County code limits you to two shingle layers, and most of these homes are already there.
Our reputation here is built on showing up when we say we will, documenting what we find with photos from your actual roof, and standing behind the work with our written 90-Day Done Right Promise. No paperwork, no arguing - if it’s not right, we make it right. Westbury homeowners call us because they remember the last contractor who disappeared, and they want a crew that will still be in the phone book next spring.
A live person answers every call, day or night, including weekends and during storms. Our technicians are background-checked and uniformed - the same standard we’d hold for work done in our own mother’s home. And we offer upfront pricing: the number on the estimate is the number on the invoice.
Our Roof Replacement & Installation Services in Westbury
Full Roof Replacement
Most Westbury homes we see are on their second or third roof system. The original 1945-1965 construction used rafter-framed roofs with minimal attic ventilation, and many carry compacted felt underlayment from prior re-roofing cycles that traps moisture and accelerates deck rot. A full tear-off lets us inspect the deck, replace damaged sheathing, and install proper ventilation and ice-and-water shield at the eaves - critical in a village where nor’easters dump heavy wet snow and ice dams form at those low Cape Cod eaves.
On a 1954 Cape Cod on Maple Avenue, we found three layers of asphalt shingles with the original undersized step-flashing buried under two re-roofs. We stripped to the deck, installed code-compliant GAF step-flashing with ice-and-water shield on the dormer walls, and used a six-nail fastening schedule per Nassau’s High Wind Zone. The homeowner finally got a leak-free winter.

New Construction Roofing
For new builds and major additions in Westbury, we install complete systems from the deck up, designed to Nassau County’s High Wind Zone requirements from day one. That means enhanced fastening schedules, proper attic ventilation sizing, and step-flashing at dormers that won’t become the weak point in twenty years. We coordinate with your builder’s timeline and pull permits through the Village of Westbury directly.

Asphalt Shingle Installation
Asphalt shingles remain the practical choice for most Westbury ranches and Capes, and we install them right. We work with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - no substitutions, no “equivalent” products you didn’t approve. For Westbury’s nor’easter exposure, we specify architectural shingles with a 130-mph wind rating and install to the six-nail pattern Nassau County requires. A typical 1,800-square-foot Westbury ranch runs $12,500-$18,500 for a full tear-off and asphalt replacement.

Flat Roofing
Many Westbury Capes have flat-roofed porch additions or dormer sections that were never designed for shingles. We replace these with proper low-slope systems - modified bitumen, TPO, or EPDM - installed to manufacturer specifications with correct drainage and flashing integration to the pitched roof above. Flat sections are where we most often find prior owners tried to save money with shingles on a slope too low, and where water ponds and finds its way inside.

Common Roof Replacement & Installation Problems We See in Westbury Homes
- Compacted felt underlayment from two prior re-roof cycles traps moisture against the deck on Westbury’s 60-80-year-old rafter-framed roofs. By the time you see a ceiling stain, the plywood or plank sheathing underneath may be spongy. A full tear-off is the only way to find and fix it.
- Missing or undersized step-flashing at dormer sidewalls on 1950s Capes has been shingled over and rusted through, causing hidden wall leaks that appear as mysterious interior water damage. Out-of-area crews consistently miss this because they don’t know to look for it.
- Ice dam formation at low Cape Cod eaves during nor’easters is exacerbated by minimal attic ventilation in original postwar construction. Water backs up under shingles and into soffits. Proper tear-off replacement with ice-and-water shield and added ventilation breaks the cycle.
- Three layers of shingles exceeding Nassau County code puts homeowners in violation and hides deck damage. We see this constantly on Westbury’s older homes. A fourth layer is not an option - it’s a full tear-off, done to code.

FAQs - Roof Replacement & Installation in Westbury
No - Nassau County code prohibits more than two shingle layers, and a fourth layer would overload the rafter framing common to 1940s-1960s Westbury construction. We need to do a full tear-off, inspect the deck for rot, and install a system that meets current code. The good news: that lets us fix the hidden problems, like compacted felt and undersized flashing, that caused your last leak. Call (866) 756-1978 for a free estimate - we’ll show you exactly what we find.
On Westbury’s 1950s Cape Cods, dormer sidewall step-flashing was routinely undersized at original construction and has been shingled over - not re-flashed - through one or two subsequent re-roofs. Water finds the gap, especially during wind-driven nor’easter rain. We strip to the deck, install code-compliant step-flashing with ice-and-water shield, and integrate it properly with the new shingle system. It’s the most predictable repeat call we get in the village, and it’s fixable for good.
We frequently specify IKO Cambridge or Atlas StormMaster architectural shingles for Westbury homes. Both carry 130-mph wind ratings and install to the six-nail pattern required in Nassau County’s High Wind Zone. The specific choice depends on your roof pitch, color preference, and whether your insurer offers discounts for certain impact-rated products. We’ll walk you through it during your free estimate.
Yes - the Village of Westbury requires a building permit for any roof replacement, and Nassau County code governs the work itself, including the two-layer maximum and High Wind Zone fastening. Ridgeline pulls permits as part of every job; you don’t handle the paperwork. We also schedule required inspections so your project closes out properly with the village.
Usually no - asphalt shingles require a minimum slope to shed water, and most Westbury porch flat roofs are too low. We replace them with proper low-slope systems: modified bitumen, TPO, or EPDM, installed with correct drainage and integrated flashing to the pitched roof above. Shingles on a flat roof are a temporary patch that guarantees future leaks. We’ll show you the right way to fix it permanently. Call (866) 756-1978.
