subject: Protect Your Coastal Home Roof From Algae And Decay [print this page] Algae is one of the leading causes of roof damage and shingle deterioration in coastal homes. As green and black algae forms on your roof, it shortens the lifespan of the shingles leading to premature roof replacement. Coastal houses are very vulnerable to roof problems due to factors that inland houses do not face like salt air and ocean breezes.
Fungus On Roof
Fungus is an algae that is dark brown, green or black in colors and causes streaking on roof shingles. At times these streaks are thought to be things like soot, dirt, or moss, which is usually a mistake. Areas that are warmer with high humidity levels are more likely at risk. This makes coastal houses a prime target for algae accumulation on coastal roofs.
Cleaning Verses Replacement
Certain methods of cleaning the roof can cause unneeded wear and tear to your shingles. Pressure washers, strong chemicals, and walking on the roof can damage the shingles and wash away the granules that make up the shingle. Fortunately, some of the latest shingles come in an algae-resistant version, alleviating unsightly streak and maintenance hassles.
You can also buy high quality shingles that have a algae-resistant barrier built-in. The algae-resistant barrier protects the shingles from streaks caused by algae. CertainTeed produces an asphalt shingle with an algae-resistant Streak-Fighter feature in the shingle.
In Closing
Check your roof regularly for steaks from algae. When you see algae starting to develop, it's time to get it cleaned before it gets any worse. Purchase a roof cleaning product to clean your roof or hire a roofing professional who can do this for you. When it becomes time to replace the roofing shingles, check out your options for a shingle with algae protection.
