A & S Roofing | Roofing Services in Staten Island, NY 10305

Ice dams often form due to poor attic ventilation and insulation, which cause uneven roof temperatures. Our new roof and replacement services include a thorough assessment of your attic's ventilation system. We install high-quality, properly sealed underlayment and ice & water shield along the eaves—critical areas where dams form. This creates a water-tight barrier, preventing meltwater from seeping under your shingles and causing interior damage, a common issue for local homes after winter storms.

Moss thrives on shaded, moist surfaces and can compromise your siding's integrity. For repair or replacement, we use durable, low-maintenance materials like vinyl or fiber cement that resist moisture absorption and are less prone to moss attachment. We ensure proper installation with adequate drainage and sealing to prevent water from getting behind the siding. For existing moss issues, we can safely remove it before repairs and recommend solutions like trimming back tree branches to increase sun exposure on your Staten Island home.

Not always. It depends on the extent of the damage. Moss can lift shingles, allowing water underneath, but often the underlying decking is still sound. We start with a detailed inspection to assess the shingle condition and any wood rot. Many times, a professional moss removal and targeted roof repair of affected areas are sufficient. However, if moss growth is widespread and has caused significant granule loss or decay, a roof replacement may be the most cost-effective, long-term solution to ensure your home is fully protected.
