RH Renovation NYC completed a full asphalt shingle roof installation on a residential property in Westchester County, replacing an aging roofing system that had reached the end of its service life. The project addressed cracked and curling shingles, granule loss, and reduced protection against wind and moisture — common issues on Westchester roofs after 20+ years of exposure to heavy snow load, seasonal storms, and summer heat.
The existing roof was fully torn off down to the deck, allowing our crew to inspect the sheathing and repair any weakened or damaged sections before installation began. A new synthetic underlayment and ice-and-water shield were installed at the eaves and valleys, followed by new step and valley flashing at all roof-to-wall transitions.
GAF architectural shingles were then installed to manufacturer specification, along with new ridge ventilation to protect the roof deck from heat and moisture buildup year-round. The project was completed with a full site cleanup, leaving the homeowner with a durable, factory-warrantied roofing system built for Westchester County’s weather.
Shingle Roofing Built for Westchester’s Climate
Westchester County homes take a beating from every direction: heavy winter snow load, spring wind and hail, and summer heat that bakes a poorly ventilated attic from underneath. Asphalt shingle roofing remains the most common — and most cost-effective — solution for that mix of conditions, but only when it’s installed correctly. RH Renovation NYC is a GAF Master Elite® contractor, a certification held by only the top 2% of roofers in the United States, and our crews install shingle roofing systems throughout Yonkers, White Plains, Scarsdale, New Rochelle, Mount Vernon, Tarrytown, Ossining, Peekskill, and the rest of Westchester County.
A shingle roof is more than the shingles themselves — it’s a layered system of decking, underlayment, ice-and-water protection, ventilation, and flashing working together. If you’re comparing shingle roofing against other systems, our roofing services covers inspection, repair, and full installation across all the roofing types we work with.
Signs a Westchester Home Needs Shingle Roof Replacement
- Shingles that are cracked, curling at the edges, or missing granules in the gutters
- Bald patches where granule loss has exposed the asphalt mat beneath
- Daylight visible through the attic roof boards, or staining on interior ceilings
- A roof that’s 20+ years old — the typical service life of a standard three-tab or architectural shingle system
- Ice dams forming along the eaves every winter, often a sign of failing ventilation or ice-and-water shield
- Missing or lifted shingles after a wind or hail event
Our Shingle Roof Installation Process
Every installation follows the same disciplined sequence, regardless of the home’s size or roof pitch:
1. Tear-Off and Deck Inspection
We remove the existing roofing down to the deck, then inspect the sheathing for rot, soft spots, or storm damage. Any compromised decking is replaced before a single new layer goes down — installing new shingles over a weak deck is one of the most common causes of early roof failure.
2. Underlayment and Ice-and-Water Shield
A synthetic underlayment goes down across the full roof, with self-adhering ice-and-water shield membrane installed at the eaves, valleys, and any roof penetrations — the areas most prone to ice damming and wind-driven rain in a Westchester winter.
3. Flashing at Valleys, Chimneys, and Skylights
New step flashing and valley flashing are installed at every roof-to-wall and roof-to-chimney transition. If your home also has a skylight or chimney, these penetrations get the same attention as the field of the roof — they’re the most common leak points on any shingle roof.
4. Shingle Installation
Shingles are installed per manufacturer specification for nail placement, exposure, and pattern, which is what keeps a GAF warranty valid. We work with architectural (dimensional) shingles for most Westchester homes, since they hold up better to wind uplift than older three-tab styles and carry a longer service life.
5. Ridge Ventilation
Proper attic ventilation is installed along the ridge to let heat and moisture escape year-round. Without it, summer heat shortens shingle life from the underside, and winter moisture buildup increases the risk of ice dams — both are common causes of premature shingle roof failure in Westchester homes with older, undervented attics.
6. Final Cleanup
All tear-off debris, packaging, and stray nails are removed from the property, including a magnetic sweep of the yard and driveway, before the crew leaves the site.

Frequently Asked Questions
How long does a shingle roof installation take in Westchester County?
Most residential shingle roof replacements take one to three days, depending on roof size, pitch, and how much deck repair is needed. Larger homes or roofs with multiple valleys and dormers can take longer.
What’s the difference between three-tab and architectural shingles?
Three-tab shingles are flat and uniform, with a shorter service life and lower wind resistance. Architectural (dimensional) shingles are thicker, layered for a more textured look, and generally rated for higher wind speeds and a longer warranty — most Westchester installations now use architectural shingles.
How much does shingle roof installation cost in Westchester County?
Cost depends on roof size, pitch, material tier, and the amount of deck or flashing repair needed. Our roof replacement cost calculator gives homeowners a planning-stage estimate, with an exact quote provided after an in-home inspection.
Do you install shingles over an existing roof, or is tear-off required?
We recommend a full tear-off for most Westchester homes. Installing new shingles over an old layer can trap moisture, hide deck damage, and void manufacturer warranties — a full tear-off lets us inspect and repair the deck before anything new goes down.
What causes ice dams on a shingle roof, and can a new roof prevent them?
Ice dams form when heat escaping from the attic melts snow on the upper roof, which then refreezes at the colder eaves. A correctly installed system — proper insulation, ridge ventilation, and ice-and-water shield at the eaves — significantly reduces the risk, which is why each is a standard part of our installation process.
Does RH Renovation NYC service my part of Westchester County?
Yes. We install and repair shingle roofing throughout Westchester County, including Yonkers, White Plains, Scarsdale, New Rochelle, Mount Vernon, Tarrytown, Ossining, and Peekskill, in addition to every neighborhood of the Bronx.
