River Roofer | Roofing Services in Hummelstown, PA 17036

We know our local humidity accelerates rust. Our approach starts with a detailed inspection of all flashing areas. For repairs, we use high-grade, rust-resistant metals like aluminum or galvanized steel, and we ensure a watertight seal with professional-grade sealants. For severely compromised flashing, we recommend complete replacement to prevent hidden water intrusion that can lead to structural damage in your attic and walls.

We use a professional, low-pressure soft wash system with eco-friendly cleaning agents specifically formulated to kill the algae at the root without damaging your shingles. High-pressure washing can strip away protective granules. Our method safely lifts the black streaks and includes a preventative treatment to slow the algae's return, helping your roof look cleaner longer despite our damp Pennsylvania climate.

Absolutely. Our comprehensive roof inspection is designed for Hummelstown homes. We meticulously examine all flashing points for corrosion, separation, or wear, and we assess the roof surface for algae growth, granule loss, and any underlying moisture damage the algae might indicate. You'll receive a clear, honest report with photos and prioritized recommendations, so you know exactly what needs attention to protect your investment.
