Algae & Your Roof: Dangers & Prevention

Construction & Contractors Articles

When it comes to problems with your roof, algae might be one of the last problems you would think exists. However, algae can be one of the most harmful substances to grace your roof, with it damaging your tiles and with the potential to shift itself under your tiles and make its way into the underbelly of your ceiling, it also lends itself to potentially damaging the interior of your house as well. This brief article will serve as a primer for you about how algae damages your roof and how you can go about ameliorating this situation.

What Causes Algae Growth?

The primary reason for algae and various forms of moss and lichens growing on your roof is a lack of sun. Shady, cool areas are the perfect spots to serve as ground zero for algae and moss to take roost upon your roof. If you live in areas that do not receive a lot of direct sunlight, even on your roof, then your home might be ripe for an algae laden area. People that make their homes in heavily wooded areas tend to have a greater frequency of receiving algae on their roofs, and the volume of the algae that makes their home in such areas is generally exponentially higher.

How Does Algae Harm a Roof?

Although it looks innocuous, algae can be quite damaging to your home's roof and could wind up causing you to find yourself financially harmed, as well. Cosmetic issues aside, algae can severely damage your roof's shingles.

By nesting on your shingles, algae will tend to greatly increase the wear and tear that is placed upon the shingles. Algae is a tenacious and durable form of plant life and can easily survive the winter months. In fact, in thrives in the cold. Furthermore, algae can be ever more damaging to your roof during these months. When algae freezes to your shingles, the weight it exerts upon your roof is even greater, causing further significant damage to your home.

How Can Algae Be Removed?

Although it is a nuisance, luckily, algae problems can easily be resolved with just a bit of elbow grease and know-how. Many people believe that scraping algae is the solution to their problem. Not only is this a difficult, time-consuming task, it also usually fails to remove algae for good and you will simply have to start back at square one.

Replacing your shingles should also be an option that is used only when all other options are exhausted, or if the algae has simply damaged your shingles too badly. The easiest way to rid yourself of algae is to use a solution of 50% water and 50% bleach and scrub the algae off with the substance. It is important to not use a power washer or sprayer during this task, as this can cause further damage to your shingles.

If you cannot seem to remove the algae yourself, a local roofing professional should have more powerful tools and the expertise needed to remove the algae or, if needed, replace your shingles.

How Can I Prevent Algae Growth?

There is an easy way to prevent algae from growing on your roof after you have adequately removed it. By placing six inch strips of either copper or zinc underneath your shingles at the peak of your roof, whenever there is rain on your roof, it will collect on the copper and then cascade down your roof, taking any potential algae growth along with it. On top of that, both of these metals kill algae, preventing it from even beginning to grow.

Although algae on your roof is an annoying problem, it is luckily a problem that is easily rectified and easily preventable.
