We provide expert asphalt shingle roof replacement, leak repairs, and inspections throughout Westchester County. Our services help homeowners extend the life of their roof or plan a timely upgrade. Asphalt shingles remain the most popular choice, offering an ideal balance of durability, aesthetics, and value.

When your shingle roof nears the end of its lifespan, a full replacement is often more cost-effective than continual repairs. We assess your roof, remove old materials, install underlayments and high-performance shingles, and carefully address ventilation, flashing, and areas around chimneys, walls, and skylights to ensure lasting protection and value.

We repair individual shingle blow-offs, address damaged flashing, and thoroughly investigate leaks. After inspecting your roof, we clearly explain the issues and recommend the best solutions for long-term performance, so you know exactly what’s happening. For urgent leaks, our emergency roof repair page outlines how we respond quickly to keep your home dry.

Today’s asphalt shingles are available in a wide variety of architectural profiles and colors, from classic charcoal and pewter gray, to warm, contemporary tones. We help you select shingles that compliment your siding, masonry, and trim, ensuring your roof upgrade enhances both protection and curb appeal.

A successful asphalt shingle roof is more than the shingles themselves—it’s a complete system. Underlayments, edge metal, flashing, vents, and gutters work together to direct water safely off your home. We install full roofing systems, ensuring every component is executed neatly and professionally by the same expert team.

There’s no single price for asphalt roof replacement, as costs depend on roof size, pitch, complexity, materials, flashing details, and site access. Architectural or premium shingles carry higher upfront costs but offer longer lifespan and superior performance. Every roof is unique, so we provide a detailed, no-obligation estimate outlining scope, materials, and costs before proceeding.
The 1:300 rule recommends 1 square foot of attic ventilation for every 300 square feet of attic floor space, evenly split between intake (soffit/eave vents) and exhaust (ridge or roof vents). Balanced ventilation reduces moisture, promotes a healthy attic, and improves energy efficiency. Mixing vent types incorrectly can “short-circuit” airflow.
Many shingles carry “limited lifetime” warranties, though actual performance depends on installation, ventilation, and exposure. A properly installed architectural asphalt shingle roof typically lasts 20–30 years, with lifespan influenced by shingle quality and local weather conditions.
No. We only perform complete roof removals. This allows us to inspect the deck, address underlying issues, and install modern underlayments, including new ice and water barriers. Installing shingles over old layers often fails to resolve critical problems and can worsen issues over time.
Existing flashing is carefully inspected during installation, and you’ll be advised if replacement is needed. When new flashing is required, we prefer 16 oz. copper for its durability and soldered joints, which outperform aluminum flashing that relies on caulking. Any costs for new flashing are transparently included in your proposal.
