Have Roof Streaks? Know What Could Be Causing This Problem

Posted on: 22 June 2018

One area of your home that goes relatively unnoticed is the roof. You won't really start paying attention to it unless the roof starts leaking, you see visible damage, or there is discoloration with the shingles. In the latter situation, streaks could be caused by the growth of algae. Here is what you should know about these roof streaks, including why it happens and how to fix it.

Why Roof Streaks Appear

The main reason that roof streaks will appear on your home is due to algae growth. This often happens because there are the perfect conditions for algae to grow, and with the roof out of sight, you do not notice it until the algae have grown significantly.

Algae thrive in places that are dark and humid, which can happen when moisture becomes trapped by debris in a shady area. This can be caused by a tall neighboring tree that casts a shadow across your roof all day long or part of your home's structure obstructing the sun for most of the day. Thankfully, it is easy to identify why these streaks are happening, so you can take preventative measures

How To Prevent Roof Streaks

The best way to prevent roof streaks is to remove the shade. If you have the hot rays of the sun shining down on the roof, it will dry up moisture that causes algae growth. Have nearby trees trimmed. If the home's structure is causing the shade, you may be out of luck. Just make sure that the area remains clear of debris so that water can flow to the gutters instead of becoming trapped.

You can also install a cap on your roof that will disperse zinc across the surface each time it rains. The zinc will kill off the algae before it can fully form.

How To Clean Roof Streaks

You can try to clean roof streaks on your own or hire a professional to do it for you. Cleaning algae stains will require wetting down the roof, applying an oxygen-based cleaning solution, allowing it to work into the stain, and then rinsing it off.

Of course, not everyone feels comfortable working safely on a roof. Know that you can always call a professional roofing company that specializes in cleaning discoloration. They'll be sure to get rid of the streaks so that you do not need to risk injury by going up on the roof by yourself.
