Algae On Your Roof? Here's What You Can Do
Have you noticed algae growing on your roof? If so, you likely live in an area of the country that has humid conditions, which is the ideal climate for a type of algae that is referred to as Gloeocapsa Magma to thrive. This type of algae can be an eyesore if it is allowed to spread, and it can damage shingles. The following information will help you better understand this nefarious substance and options that are available to you.
Clean your roof using chemicals that kill algae.
Sometimes people experience algae regrowth when they opt to clean the substance from their roofs, which is something that you should be mindful of in the future if you opt for a cleaning solution. Cleaning the roofing material with harsh chemicals every now and then may not pose a problem, but if you find yourself frequently cleaning algae from the roof with chemicals, then there is a possibility that the chemicals could damage the shingles. You will likely use a pressure washer to clean the shingles, and this piece of equipment could negatively impact the lifespan of your shingles if used incorrectly.
People commonly use bleach or commercial cleaners that are designed to kill algae. Keep in mind that using these chemicals could also cause environmental issues. For example, residual water mixed with the chemical solution of your choice could drain away and kill flowers or other vegetation. It might also get mixed with storm runoff water.
Choose a roofing material that is algae resistant.
You may find that the reoccurrence of algae is frequent and bothersome. This leads some people to seek out roofing replacement services. If you desire shingles due to their aesthetics or because they are an affordable roofing material, inquire about algae resistant shingles. These types of shingles go through a special manufacturing process. Copper granules are combined with the traditional shingle materials to make them resistant to algae growth. It is important to note that "algae resistant" does not mean that the shingles will never be compromised by algae. It simply means that it is less likely to occur. For example, algae resistant shingles will age and naturally break down over time. As the materials deteriorate, the resistant qualities of the shingles may also deteriorate. You may want to consider exploring a different type of roofing material, such as metal, which is resistant to algae, mold, and mildew.
A residential roofing contractor is a good resource to use to determine the best approach to keeping algae off of your roof. They also offer the best option for cleaning algae from rooftops because they know how to navigate dangerous roofs as well as the best methods of cleaning them to prevent roofing damages.
