Magnum Contracting Group | General Contractors & Roofing in Glen Cove, NY 11542

Roof valley leaks are a common issue in our area due to heavy rain and debris accumulation. Our team starts with a detailed inspection to pinpoint the exact cause—often damaged flashing or compromised shingles. We then provide a clear repair plan, which may involve resealing the valley, replacing sections of flashing, or installing new, high-quality underlayment to ensure a watertight seal that withstands Long Island weather.

Our remodeling process is designed to be straightforward and collaborative. We begin with a consultation to understand your vision, budget, and functional needs. From there, our licensed team manages all phases, including demolition, plumbing and electrical work (coordinating with licensed subcontractors as needed), installation, and finishing. We handle the details so you can focus on choosing fixtures and finishes, ensuring a smooth transformation of your Glen Cove home's most-used spaces.

Yes, we provide a full range of roofing services. For many homes, a targeted repair—like fixing a few damaged shingles or sealing a leak—is all that's needed. We always recommend an inspection first. If a repair isn't sufficient or your roof is near the end of its lifespan, we offer complete roof replacements using durable materials suited to our local climate. We'll clearly explain your options so you can make an informed decision for your home's protection.
