Mt Sinai sits directly on Long Island Sound. Salt air, coastal humidity, heavy nor'easters, and freeze-thaw cycles put constant stress on residential roofs—and small issues escalate fast.

- Leak tracing and accurate diagnosis before any repair
- Quality materials matched to existing roofing
- Flashing and sealing details done right the first time
- Clean job sites and professional workmanship throughout
