Black streaks on asphalt shingles are often caused by roof algae, not just surface dirt. In Ottawa and Eastern Ontario, shaded areas, humidity, and trapped moisture create ideal conditions for algae growth.
Over time, these dark streaks can spread across the roof, reduce curb appeal, and contribute to faster shingle deterioration if left untreated.
Professional roof algae removal helps clean the roof safely while protecting the shingles underneath.
Roof algae can affect asphalt shingles in several ways:
Roof algae is not just a cosmetic issue. As growth spreads, it can trap moisture, feed on shingle fillers, and contribute to granule loss and premature deterioration.
Professional soft wash roof cleaning is designed to:
Because asphalt shingles are a protective roofing system, keeping them clean and free of harmful growth helps preserve both appearance and long-term performance.
A professional algae removal service is not just about appearance. It is about protecting a usable roof before deeper deterioration takes hold.
Most dark roof streaks are caused by algae growth, not ordinary dirt or staining.
Professional soft wash roof cleaning removes algae safely without the damage caused by aggressive pressure washing.
Algae growth can hold water against the shingle surface, which may accelerate surface wear over time.
Removing algae early helps preserve curb appeal, reduce surface wear, and avoid more costly roofing issues later.
Dark streaks on asphalt shingles are often caused by algae growth, not ordinary dirt. In shaded or humid areas, algae can spread across the roof surface and make the home look older than it is.
