Dark Streaks on Your Roof: What They Are and How to Address Them
Roofs are more than just a protective barrier for our homes; they're a reflection of our home's overall health and aesthetic appeal. Over time, many homeowners notice dark streaks forming on their asphalt shingles, leading to concerns about the roof's integrity and appearance. At Unisource Roofing, we understand these concerns and are here to shed light on this common issue.
The Mystery of Dark Streaks on Asphalt Shingles
Dark streaks on asphalt shingles are often mistaken for dirt, mildew, or even defective shingles. However, the primary cause of these unsightly streaks is a blue-green algae known as Gloeocapsa Magma. This algae's growth spores are airborne, making it easy for them to settle and grow on roofs, especially in humid regions.
Addressing Algae Discoloration on Your Roof
Removing algae discoloration from an asphalt roof can be challenging, but it's not impossible. Here's a step-by-step approach:
Safety First: Always prioritize safety. If you're considering cleaning the roof yourself, remember that wet roofs can be slippery. Use fall protection, wear slip-resistant shoes, and ensure you have eye protection.
Preparation: Cover all ground vegetation directly beneath the roof to protect them from the cleaning solution.
The Cleaning Solution: Mix equal parts of bleach and water (1:1 ratio) to create an effective solution against algae.
Application: Spray the solution onto the affected areas of the roof and let it sit for 10-20 minutes. Avoid scrubbing or using high-pressure washing as it can damage the shingles.
Rinsing: After the waiting period, rinse the roof thoroughly with water. Ensure that the surrounding greenery (grass, bushes, shrubs) is also flushed with water to remove any residual bleach.
Repetition: In cases of extensive algae growth, you might need to repeat the process. However, if done correctly, your roof should remain clean for up to two to five years.
Algae's Impact on Asphalt Shingles
While algae discoloration can be an eyesore, it doesn't necessarily compromise the performance of asphalt shingles. It's primarily an aesthetic concern that might affect your home's curb appeal.
The Solution: Algae Resistant Shingles
Innovation in the roofing industry has led to the development of algae-resistant shingles. These shingles are infused with metals, like copper, known for their algae-inhibiting properties. Observations revealed reduced algae staining beneath metal vents or flashings on roofs, leading to this breakthrough. Unisource Roofing offers a range of algae-resistant asphalt shingles designed to combat this very issue.
