The black streaks you see are actually a type of algae that thrives in our humid climate. While some DIY washes offer a temporary fix, they can damage shingles. We use a professional, low-pressure cleaning solution specifically formulated to kill the algae at the root without harming your roof's integrity. To prevent regrowth, we can also install zinc or copper strips along the ridge. These metals release ions with rainfall that naturally inhibit algae, providing years of protection.

Chimney flashing leaks are very common here due to temperature swings and settling. The sealant (caulk) around the metal flashing dries out, cracks, and fails, allowing water to seep in. A permanent repair isn't about just re-caulking. We carefully remove the old material, inspect the step flashing and counterflashing for rust or damage, and then re-integrate new flashing with the roof system using proper techniques and high-grade sealants. This creates a watertight, long-lasting barrier that moves independently of the chimney to prevent future leaks.

It depends on the extent of damage, the age of your roof, and the condition of the underlying deck. During our free inspection, we look for key signs: widespread curling or missing shingles, significant granule loss in gutters, multiple leaks, or daylight visible through the roof boards in the attic. For localized issues like a few damaged shingles or one leaky flashing, a repair is often sufficient. However, if the roof is near the end of its lifespan (typically 20-25 years for asphalt shingles) or has sustained storm damage across large sections, a replacement is usually the more cost-effective, long-term solution to protect your investment.
