As a general rule, it is recommended to have your roof washed every 2-3 years to remove any accumulated dirt, grime, and organic growth, such as algae, moss, and lichen. However, if you live in an area with high humidity or frequent rainfall, you may need to have your roof washed more frequently to prevent the growth of harmful organisms.

Soft washing is a low-pressure, chemical cleaning method used to remove dirt, algae, mold, mildew, moss and other types of stains and contaminants from exterior surfaces. Unlike pressure washing, which uses high-pressure water to blast away grime, soft washing uses a gentle stream of water combined with specialized cleaning solutions to effectively clean and sanitize surfaces without damaging them. Soft washing is commonly used on surfaces such as roofs, siding, decks, fences, and driveways, and is particularly effective in areas with high humidity and frequent rainfall, where mold and mildew growth is common.

Yes, using a pressure washer on your shingle roof can potentially cause damage to the shingles and roofing materials if done improperly. Shingles are designed to be water-resistant, but high-pressure water spray can dislodge and loosen the protective granules on the surface of the shingles, leading to premature deterioration and the need for costly repairs or replacement. In addition, high-pressure water spray can also force water under the shingles and into the underlying roof deck, causing water damage and leaks. It can also be dangerous to walk on a wet and slippery roof while using a pressure washer, increasing the risk of falls and injuries.

Therefore, it is not recommended to use a pressure washer to clean a shingle roof. Instead, it is best to use a gentle cleaning method such as soft washing, which uses low-pressure water spray and specialized cleaning solutions to safely and effectively remove dirt and organic growth from the roof's surface without causing damage. It is recommended to hire a professional roof cleaning service that has experience with soft washing to ensure that the process is done correctly and safely.

Black streaks on a roof are typically caused by a type of algae called Gloeocapsa Magma. This type of algae is commonly found on roofs in areas with high humidity and warm temperatures. The black streaks are actually the pigmented cells of the algae, which protect it from UV rays and help it to absorb more moisture and nutrients. The algae can spread quickly on roofs, especially those with asphalt shingles, which provide a good surface for the algae to cling to. The algae feed on the limestone filler that is used in asphalt shingles, and as they grow and spread, they can cause the shingles to deteriorate more quickly, leading to premature roof failure. Regular roof cleaning can help prevent the growth and spread of algae on a roof. Soft washing, as mentioned earlier, is an effective method for removing algae and other stains from a roof without causing damage to the shingles or other roofing materials. It is important to hire a professional to perform roof cleaning, as walking on a roof can be dangerous and can cause damage if not done properly.
