In humid climates such as Surrey BC, moss, algae and lichen can sprout sprout on your roof, and spread rapidly. Lets take a look at each of these, and the effects they can have on your roof:
Moss: Beyond just being an eyesore, moss can lead to significant shingle damage. While it may not harm shingles as much as other forms of growth, moss accumulates dirt and thrives. As it and other growths land on the roof, they establish roots, creating a problem that worsens in winter. These growths can trap ice and water, ultimately shortening your roof’s lifespan. To safeguard your roof, regular moss removal is essential.
Algae: If your roof’s color no longer matches your memory, algae growth could be the culprit. Algae can cause discoloration, turning a brown roof black. Sometimes, it may give your roof a dirty, streaked appearance, often mistaken for dirt, tree debris, or soot. The good news is that removing algae is a straightforward process that can extend your roof’s longevity.
Lichen: Lichen growth poses a significant threat to your roof’s integrity. Although lichen is commonly found on tree trunks, it also utilizes a robust root system to feed on limestone, potentially leading to extensive damage.
Pressure washing an asphalt, tile, or cedar roof and cause irreversible damage! That is why we use the soft wash method to clean your Surrey roof safely and effectively, without the use of high pressure, which will remove granules from your asphalt roof shingles. Our soft wash roof cleaning kills moss, algae and mildew down to the roots, and causes the roof moss to disintegrate and break down over time.
A soft wash simply means a low-pressure wash using chemicals. Some customers may ask, which chemical is used?, and is it harmful to my pets, children or plants?
We use a liquid chlorine base, as well as other soaps and surfactants in our soft wash mix, which is standard across the roof wash industry, besides some acceptions with cedar roofs, which are often cleaned with Oxygen bleach instead.
When used correctly, chlorine is safe, and affective at cleaning, killing, and preventing organic growth, without harming the shingles of your roof. When removing shingle moss, chlorine, or bleach, is the only way to go!
