Those black streaks are a common issue here due to our humid climate. It's a type of algae, not mold, but it can trap moisture and degrade shingles over time. We recommend a professional soft wash treatment, not high-pressure washing which can damage shingles. This safely removes the stains and includes an application to help prevent regrowth, protecting your roof's lifespan and curb appeal.

In our experience with Cottrellville homes, chimney flashing is the most common culprit for leaks. The metal flashing can crack or loosen due to temperature swings and settling. However, it could also be deteriorated mortar (the crown or joints) or damaged chimney caps. We perform a detailed inspection to pinpoint the exact source—whether it's the flashing, brickwork, or another issue—before recommending the precise, lasting repair needed.

Absolutely, a leaking flashing can almost always be repaired without a full roof replacement. In most cases, we can carefully remove the compromised flashing, install a new, properly sealed section using durable metals like aluminum or copper, and integrate it seamlessly with your existing shingles. This targeted repair is a cost-effective solution that addresses the specific leak, saving you the expense of premature re-roofing.
