Why Clean An Asphalt Roof?
Cleaning an asphalt roof with sodium hypochlorite (SH), a common bleach solution, is often done to remove algae, moss, and lichen. These organisms can thrive on asphalt shingles, especially in damp, shaded areas. Over time, they can damage the shingles, reduce their lifespan, and affect the roof’s overall appearance.
Sodium hypochlorite is effective because it acts as a powerful disinfectant and can break down the organic matter that supports algae and moss growth. Here’s a quick rundown on why and how it’s used:
Algae and Moss Removal: Sodium hypochlorite helps to kill and wash away algae and moss. This can prevent further growth and potential damage to the shingles.
Improved Appearance: Removing stains and growth can restore the roof’s appearance, making it look cleaner and more attractive.
Extended Roof Lifespan: By preventing or removing damaging growths, you can help extend the life of the roof and maintain its effectiveness.
Preventing Damage: Algae and moss can trap moisture, which can lead to shingle deterioration and potential leaks. Cleaning helps mitigate this risk.
What Is Gloeocapsa Magma?
Gloeocapsa magma is a type of cyanobacteria, often referred to as blue-green algae, that commonly grows on rooftops. It thrives in moist, shaded environments and is frequently seen on asphalt shingle roofs, particularly in humid or rainy climates. This organism is not just unsightly; it can cause significant damage to roofing materials over time.
The main issue with Gloeocapsa magma is its ability to produce a dark pigment called melanin. This pigment helps the organism absorb and retain heat, which can accelerate the deterioration of roofing materials. As the algae spread, they trap moisture against the roof, leading to increased wear and tear on the shingles. This can result in reduced lifespan of the roofing system, and in some cases, lead to costly repairs or replacements.
To combat this problem, many homeowners turn to a solution known as sodium hypochlorite (SH), commonly found in household bleach. Sodium hypochlorite is effective at removing Gloeocapsa magma from roofs. It works by breaking down the algae’s cell walls, which helps to eliminate the pigment and the algae itself.
