Algae stains, often appearing as black streaks, are common here due to our humid climate. While they don't typically damage the shingles immediately, they can trap moisture and accelerate wear. We recommend a professional soft wash treatment specifically designed for roofs, which safely removes the algae without damaging the shingle granules. We do not recommend high-pressure washing, as it can strip away the protective granules and void manufacturer warranties.

On Kaua'i, it's often a combination of both. The intense UV exposure and salt air can cause shingles to age and become brittle faster than in other climates. High winds from passing showers can then lift and curl these already-weakened edges. We offer free inspections to assess the condition, determine the cause, and advise whether a repair or a full replacement is the most cost-effective solution to protect your home.

We recommend a professional inspection at least once every two years. Given our local weather patterns—frequent rain, strong winds, and high humidity—small issues like a lifted shingle or minor leak can quickly become major problems. A proactive inspection allows us to catch and repair minor damage early, saving you significant money and preventing interior water damage to your home.
