How To Prevent Roof Algae Growth

Do you live in a climate where your roof is prone to algae growth? If so, you may be wondering what you can do to prevent it from happening. While algae is not pleasant to look it, know that it has the potential to damage your roof. Here are some helpful tips that will prevent algae from growing in a place where you do not want it.

Select The Proper Kind Of Shingles

The best way to prevent algae growth starts with the type of shingles on your roof. If your home is located in a climate where it's warm and humid, you'll want to select a roofing material that has copper and zinc in it.

If new roofing material is not an option for you, then you can accomplish the same thing by installing a metal roof cap. This releases the copper and zinc across the surface of your roof every time that it rains. These metals kill the algae before it can start growing and cause damage.

Fix Drainage Issues

Algae tends to grow in places on your roof where it is moist, which is likely due to drainage issues. It could be something as simple as debris that collects on your roof in a certain spot, causing moisture to be trapped underneath it and grow mold.

If you fix these issues, the water will be able to reach the gutters and go into your downspouts. For example, in the instance where you have debris trapped on your roof, look into removing tree branches that hang over your roof and drop leaves.

If you have a flat roof with places that have dips in the surface that cause pooling water, you'll need to eliminate the dips so that water moves towards the drains.

Clean The Roof

If algae growth is a recurring issue, you may be better off cleaning the roof proactively rather than waiting for it to look bad. Cleaning a roof with a special cleaning solution designed to prevent algae growth can give you a window of time where algae won't grow back. In addition, it will help the singles look great since they'll be restored to their natural color.
