R G Roofing | Roofing Services in Mineola, NY 11501

Shingle curling in Mineola is often caused by moisture trapped in the attic from poor ventilation, combined with our local temperature swings. This makes the shingles buckle and lose their protective seal. We fix it by first diagnosing and correcting the ventilation issue, then replacing the damaged shingles with matching, high-quality materials to restore your roof's integrity and appearance.

Those dark streaks are Gloeocapsa magma algae, common in our humid Long Island climate. We use a professional, low-pressure cleaning solution specifically formulated to kill the algae and lift the stains without the high pressure that can strip away the protective granules on your asphalt shingles. This safely restores your roof's look and helps prevent the stains from returning quickly.

Not every leak means a full replacement is needed. Many leaks in Mineola homes are localized, often around flashings, vents, or in a small section of damaged shingles. We'll perform a thorough, honest inspection to find the exact source. If the overall roof structure is sound, we can usually perform a targeted repair that solves the leak and extends your roof's life, saving you significant cost.
