A locally owned Staten Island roofing company built on a simple premise: honest advice, premium work, and a team you can trust to show up and do the job right.
Alter Phase Roofing Contracting is a locally owned and operated roofing company based in Staten Island, New York. We serve homeowners, property managers, and businesses across all five NYC boroughs.
We were founded on the belief that roofing should be straightforward: honest assessments, transparent pricing, quality workmanship, and a company that stands behind what it builds. No drones. No quick measurements from the street. No vague estimates. We physically climb every roof, walk every surface, and tell you exactly what we find.
That approach has earned us a 5-star Google rating and a growing reputation as the roofer that Staten Island and NYC residents recommend to their neighbors.
These aren't marketing taglines. They're the standards every member of our team is held to on every job.
We never quote from a drone or satellite image. A licensed crew member physically walks every roof, every time. This is non-negotiable — it's how we find what others miss.
You'll know exactly what we found, what we recommend, what it costs, and why. No inflated estimates, no manufactured urgency, no confusing scope documents.
We'd rather take an extra day and do it right than rush and leave behind a problem. Every project is treated as if it were our own home — materials, installation, and cleanup included.
When we commit to a time, we're there. When we promise a deadline, we hit it. The number of contractors who simply don't show up is exactly why we built our company around reliability.
We live and work in the communities we serve. Protecting Staten Island homes and NYC buildings is personal to us. Your property is in good hands because we treat it like our own neighborhood.
Our work is backed by written warranties on both materials and workmanship. If something goes wrong, we come back. That's not a policy — it's our reputation at stake.
Mark and his team did an excellent job replacing my roof. He climbed up to investigate, unlike other contractors using drones. Honest opinion, great communication, and fair pricing.
Professional, very responsive, and took the time to educate us on what the project entailed. Really happy with the outcome. Worth every penny. 100% will recommend to family and friends.
They walked my roof and identified all trouble spots. Price and timeline were clearly communicated. Demolition to clean-up — all handled with professionalism. Would hire again.
Free inspections, transparent estimates, and work you can trust.
