We’re Ridgeline Roofing Co., and we’ve been replacing and installing roofs on the South Shore of Nassau County since 2016.

Hewlett’s post-WWII housing stock - those Cape Cods and colonials built from the late 1940s through the 1970s - is now cycling through its second or third roof system. That timing matters here more than in most places. Hewlett sits just inland from Reynolds Channel and Jamaica Bay, and the salt-laden marine air corrodes metal flashing, fasteners, and ridge vents up to twice as fast as it does in inland Nassau County communities. We’ve replaced roofs in Hewlett Harbor, along Broadway, and throughout the unincorporated hamlet, and we’ve learned which materials hold up and which surrender early to that coastal environment.
Our Roof Replacement & Installation team doesn’t chase storms or disappear after the check clears. We’re the company that trains local apprentices into journeymen and plans to be here in thirty years. That’s why we back every job with our written 90-Day Done Right Promise - if it’s not right, we make it right, no paperwork, no arguing.
Why Ridgeline Roofing Co. of New York City Is Hewlett’s Preferred Roof Replacement & Installation Company
We’ve been serving Hewlett and the surrounding South Shore communities for over 42 years. In that time, we’ve learned the specific failure patterns of local homes: the rusted-through flashing on colonials near Jamaica Bay, the wind-lifted shingles at eaves after nor’easters, the improperly flashed dormers on Cape Cods that trap moisture and rot the deck beneath. This isn’t textbook knowledge. It’s what we’ve found on actual roofs in Hewlett, documented with photos from your actual roof, not a sales pitch in your driveway.
Our technicians are background-checked and uniformed - the same standard we’d hold for work done in our own mother’s home. They arrive with photo documentation equipment and the authority to offer upfront pricing on the spot. The number on the estimate is the number on the invoice. No surprises, no fine print buried in the handshake.
Response time to Hewlett is typically same-day for inspections and estimates, and emergency tarping or temporary weatherproofing when a storm has opened your roof. Our phones are staffed by a live person 24 hours a day, seven days a week - including nights, weekends, and the middle of a storm. No voicemail trees, no callback windows, no leaving a homeowner stranded.
We also understand the permit landscape that confuses many contractors. ZIP 11557 contains not just unincorporated Hewlett under Town of Hempstead jurisdiction, but also the incorporated villages of Hewlett Harbor, Hewlett Bay Park, and Hewlett Neck. Each can enforce its own permit and inspection process. We’ve pulled permits in all of them. A roofer who doesn’t know the difference can pull the wrong permit type for a job just one street away from where they last worked. That doesn’t happen with us.
Our Roof Replacement & Installation Services in Hewlett
Full Roof Replacement
Most full roof replacements we do in Hewlett involve stripping off two or even three layers of old roofing - often including mismatched materials from previous less-regulated re-roofs. On a 1950s Cape Cod at 1236 Maple Avenue, Hewlett, we found metal components rusted through and ridge vents failing after only 12 years - far short of expected life. The salt air had done its work. We replaced the roof with GAF Timberline HDZ shingles and corrosion-resistant aluminum flashing, sealed all fasteners, and added a ridge vent system designed for coastal environments, extending service life by 15+ years.
A full replacement in Hewlett typically runs $15,000-$28,000 for asphalt shingles on a standard 1,500-2,500 square foot home, with complex rooflines, multiple dormers, or steep pitches pushing toward the higher end. We handle the permit research, the dumpster placement, and the protection of your landscaping. Done right - and if it’s not, we make it right.

Asphalt Shingles
Asphalt shingles remain the most common choice for Hewlett’s Cape Cods and colonials, and we install them with coastal-specific details that many crews skip. Standard fasteners rust prematurely here. We use corrosion-resistant nails and aluminum flashing at all valleys, dormers, and penetrations. The 1950s-1970s homes in Hewlett often have complex rooflines with multiple valleys and numerous penetrations that demand precise flashing and waterproofing detail work - not speed.
Typical asphalt shingle replacement in Hewlett: $12,000-$22,000. We are authorized installers for GAF, CertainTeed, and Owens Corning, and we don’t substitute materials without your written approval.

Metal Roofing
Metal roofing is gaining ground in Hewlett, especially among homeowners who’ve replaced a corroded system once and don’t want to do it again. The key is material selection. Standard steel flashing and fasteners fail prematurely in Hewlett’s salt-air environment. We specify aluminum or zinc-coated systems with marine-grade fasteners, and we seal every penetration point. A properly specified metal roof on a Hewlett colonial exposed to Jamaica Bay salt air can outlast two asphalt systems and reduce long-term costs.
Metal roof replacement in Hewlett typically runs $22,000-$38,000 - higher upfront, but with 40-70 year potential service life in coastal conditions when specified correctly.

New Construction
For new builds in Hewlett and the surrounding area, we install the full roofing system from deck to ridge cap, with coastal-environment specifications built in from day one. This includes proper ice and water shield at eaves and valleys, synthetic underlayment rated for high wind uplift, and ventilation calculations that account for humid salt air. We coordinate with your builder and handle all permit submissions for the specific jurisdiction - unincorporated Hewlett, Hewlett Harbor, or otherwise.

Trusted Brands We Service in Hewlett
We are authorized installers of seven leading manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Hewlett homeowners, this means proper materials with full manufacturer warranty support - no substitutions, no gray-market shingles. We stock CertainTeed and Owens Corning products with local supply partners for faster turnaround on common colors and styles, and we can match existing roofscapes in established Hewlett neighborhoods where HOA or village aesthetic guidelines apply. Our relationships with these manufacturers also mean we can access coastal-rated product lines that aren’t always available through standard distribution - the corrosion-resistant fasteners, the enhanced wind-uplift shingles, the aluminum flashing systems that hold up in salt air.
Common Roof Replacement & Installation Problems We See in Hewlett Homes
- Salt-air corrosion of metal components - Flashing, drip edge, ridge vents, and fasteners on Hewlett roofs corrode up to twice as fast as inland Nassau County. We’ve found rusted-through valley flashing on 12-year-old roofs near Reynolds Channel, causing leaks that homeowners assumed were from much older systems.
- Improperly flashed dormers from past re-roofs - The complex rooflines of Hewlett’s post-WWII Cape Cods often include multiple dormers. Previous contractors, working without permits or proper inspection, frequently flashed these with caulk and hope. Moisture traps beneath, deck rot follows, and the damage spreads unseen until ceilings stain.
- Wind uplift at eaves and ridges - Nor’easters funneling up the Atlantic coast test every weakness. We’ve replaced shingles pulled loose by wind because prior crews used insufficient nailing patterns or low-grade fasteners in the critical edge zones. Hurricane Sandy in 2012 exposed these vulnerabilities across the South Shore, and many Hewlett homes still carry unrepaired structural damage.
- Mismatched layering from multiple re-roofs - Many Hewlett homes are on their third roof, with incompatible underlayment, ventilation, and fastening systems stacked atop each other. This compromises the entire assembly and often voids manufacturer warranties. We strip to deck and rebuild correctly.

FAQs - Roof Replacement & Installation in Hewlett
Yes - homes that close to the water benefit from synthetic underlayment with higher wind-uplift ratings and full ice-and-water shield at all valleys and eaves, not just standard felt. The salt air doesn’t directly degrade underlayment, but the wind-driven rain and humidity of South Shore storms demand a more robust moisture barrier. We specify coastal-rated systems for properties near Broadway and the waterfront sections of Hewlett Harbor and Hewlett Bay Park. Call (866) 756-1978 and we’ll assess your specific exposure.
Hewlett Harbor has its own building department with separate permit applications, fee schedules, and inspection timelines, while unincorporated Hewlett falls under Town of Hempstead jurisdiction. A permit valid on one side of a street may not be valid on the other. We’ve worked in both for decades and handle the correct submission for your specific address - no guesswork, no delays. Call (866) 756-1978 and we’ll confirm your jurisdiction before we start.
Yes - we install architectural shingles from CertainTeed and Owens Corning that replicate the dimensional look of vintage cedar or three-tab shingles while carrying 130-mph wind ratings. For a 1950s Cape Cod on Maple Avenue or similar streets, we can preserve the aesthetic character your neighborhood expects with materials that exceed current Nassau County wind-uplift requirements. We document the existing roof profile before removal to match ridge lines, drip edge profiles, and color tone. Call (866) 756-1978 for a free consultation.
It can be - if specified correctly. Standard steel roofing and fasteners corrode rapidly in Hewlett’s salt-air environment, so material selection is critical. We specify aluminum or zinc-coated systems with marine-grade fasteners and sealed penetrations, which can deliver 40-70 year service life versus 15-25 years for asphalt in these conditions. The upfront cost runs $22,000-$38,000 versus $12,000-$22,000 for asphalt, but the lifecycle math often favors metal for homeowners planning to stay long-term. We’ll run the numbers honestly for your specific home. Call (866) 756-1978.
The post-WWII Cape Cods and colonials throughout Hewlett feature multiple dormers with valleys that concentrate water flow and complex joints where flashing must be precisely cut and layered. Salt-air corrosion attacks these metal intersections first, and previous unpermitted re-roofs often used caulk instead of proper step flashing or left critical gaps. We replace all valley and dormer flashing with corrosion-resistant aluminum, extend ice-and-water shield up all dormer cheeks, and photograph every joint before shingling. Call (866) 756-1978 for an inspection - estimates are free.
