3 Ways Roof Algae Is Costing You Big

Updated: Sep 28, 2018


Yes, the ugly black streaks on your roof is a form of algae called Gloeocapsa Magma. This algae does more than just making your roof look ugly, it is costing you money. The good news is that it can be removed.



1. Higher Energy Bill


Dark colors naturally attract more sunlight than lighter colors. The Gloeocapsa Magma is a dark black color and in some cases, it covers the whole roof. The extra heat retained by the roof means that your A/C unit has to run longer in the summer to keep the house cool. Over the course of a summer, that extra energy consumption adds up.


2. Premature Roof Replacement


If the Gloeocapsa Magma is not treated and removed it can create a very fertile area for lichen and moss to grow. Both lichen and moss can cause serious damage to a roof because they dig roots into the shingles. These root systems will force the roof to leak prematurely.


About one in every three people who decide to replace their roof do so simply because it is covered with algae not knowing that it could be cleaned for a fraction of that price.


3. Lower Home Valuation

This one detail could be worth thousands of dollars to anyone selling a home. It is much easier to sell a home that looks amazing from the curb than one that has black streaks covering the roof. For people looking to buy a house, they could easily mistake the roof as damaged and in need of being replaced.

Note- Do NOT use a pressure washer to clean your roof. This will cause serious damage to the shingles. For tips on cleaning it yourself send me an email and I will be glad to help. However, if you have a steep roof I don't recommend doing it yourself.
