Building new in NYC? We work with your builder and architect to deliver a code-compliant, perfectly installed roof on schedule — from the deck up.
New construction roofing requires precise coordination, code knowledge, and the ability to work within a builder's schedule. Alter Phase has the experience to deliver on all three.
We work with general contractors, architects, and homeowners on new residential builds, additions, and commercial construction projects across all five NYC boroughs. Our work is inspection-ready, fully documented, and delivered on time.
NYC has specific roofing code requirements. We know them cold and ensure every installation passes inspection without delays or change orders.
We coordinate directly with your GC and schedule around the construction timeline — no conflicts, no delays caused by roofing.
Correct ridge, soffit, and attic ventilation is essential for roof longevity, energy efficiency, and preventing ice dams. We design it right from day one.
Contact us early in your project timeline — we help plan, not just install.
