There are many things that are important to consider while hiring roof cleaning contractors such as which type of products they are using. There are several warehouses in this section: one company that uses sodium hypochlorite (bleach) and one company that doesn't use this chemical.
Businesses use bleach for economic reasons: it's inexpensive, easy, and quick to apply. Bleach is a short-term roofing solution because it only covers the dirt and doesn't remove the source that created it.
However, you can also get the services of roof cleaning offered by North Shore Home Services in Vancouver.

Stains are made up of billions of cells, both living and dead. In principle they are single-celled. They are fully referred to as "algal glue". The algae glue covers the particles that cover your asphalt shingles.
Dead and living cells are entangled in a single layer of glop. Bleach is an oxidizing agent and when used with seaweed glue will treat the top surface of the stain and the stain will appear to disappear.
But the algae glue cells remain under the oxidized layer. When the top oxidation state is used up, the stain appears again, although it never goes away.
Therefore, this bleach is not a permanent solution. If you have a bleaching charter, talk to your pest control provider about finalizing your termite transaction. It is better to cut the player with bleach. Then you don't have to worry about your flora.
There are other products out there that actually crack and remove algae glue. These marker chemicals take longer to remove because the organisms have been permanently removed.
And they are safe for pets, plants and avoid maintenance. However, for contractors who value proprietary and working chemicals, you should expect a little more.
