New construction means we start with a clean deck and build the roofing system properly from the first layer. Thornwood Roofing & Maintenance has installed new roofs on hundreds of new builds across Thornwood, from custom homes to spec builds, from room additions to detached structures.

Proper ventilation is the most overlooked element in new roof installation. We calculate intake and exhaust requirements per IRC R806 based on your attic square footage. Balanced ventilation (soffit intake matched to ridge exhaust) keeps your attic cooler in summer and drier in winter, extending roof life and reducing energy costs.

Our New Roof Installation Process

1

Plan Review & Consultation

We analyze your plans for pitch, square footage, ventilation needs, and code compliance. You get a detailed proposal with material specs, timeline, and fixed pricing before any work begins.

2

Material Delivery & Staging

Materials delivered and staged on-site the day before installation. Shingle pallets, underlayment rolls, flashing stock, ridge vent, and fasteners, everything confirmed against the project spec sheet.

3

Expert Installation

Our Thornwood crew installs every layer to manufacturer specifications: underlayment, ice and water shield, drip edge, starter strip, field material, hip and ridge caps, and ventilation. Every fastener placed per the manufacturer nailing schedule.

4

Inspection & Warranty

We schedule the building inspection and walk the roof with the inspector. Your manufacturer warranty gets registered the same day the roof passes inspection. You receive warranty paperwork within a week.

Why Choose Thornwood Roofing & Maintenance for New Roof Installation?

Ventilation Design

We calculate intake and exhaust per IRC R806 for every new install. Balanced ventilation extends roof life and cuts energy costs. Most contractors skip this step.

Builder Coordination

We work directly with your GC on scheduling, staging, and inspections. On-time delivery and clean work that doesn't slow down the rest of the build.

Material Selection Guidance

Shingles, metal, flat systems. We install all of them and help you choose based on your budget, design, and the demands of NY climate.

Code Compliance

Every installation meets IRC building code and local Thornwood amendments. Proper underlayment, ice barrier, and fastener patterns documented for inspection.

New Roof Installation FAQ

It depends on your pitch, budget, and aesthetic. Architectural shingles are the most popular for residential: affordable, durable, 30-50 year warranties. Metal lasts 40-60 years but costs more upfront. Flat sections need TPO, EPDM, or modified bitumen. We help you choose during the consultation.

One to three days for most residential projects. Standard homes are typically done in one day. Larger custom builds or complex multi-material roofs take two to three days. We coordinate timing with your GC.

Synthetic underlayment meeting ASTM D6757 across the full deck. Ice and water shield per ASTM D1970 at eaves, valleys, and all penetrations. These layers are critical. They're your last line of defense if the shingles fail.
