Moss and algae can be a serious problem on any roof. Understanding what causes mold on your roof and how you can get rid of it is essential to preventing serious structural damage. Black mold itself will not cause structural damage or you wait shingles but it can cause water pooling which can place excessive loads on your roof or lead to leaks. What causes mold on the roof? Black stains start to appear on the roof when you’re roof experiences humid conditions.
It starts to appear as a blue or green color. How to remove it: One of the earliest things that you can do when you spot the signs of mold is to replace or patch shingles with a darker color. Opting for modern shingles with copper granules and a darker color can kill algae. Many homeowners also use the tactic of washing down their roof with a 50% ratio of bleach and water poured down and then sprayed off with a light mist of the hose. Do not use a pressure washer here as this can remove granules from your shingles.
Using a light scrub brush on flashing can help to free it of algae stains as well. Bleaching down the algae and doing a light scrub with the brush can help to remove the signs of moss and algae from your roof. Inserting 6 inch strips of copper or zinc along the road shingles that are closest to your roof peak can help to kill off future algae growth.
Copper works as a tool to kill off algae and if it isn’t allowed to grow at the site, this will make sure it doesn’t have the chance to grow at the bottom of your roof either.
