Black Stains on Roofing: 3 Factors You Need to Know, Richmond, Kentucky

Have you noticed black streaks on your roof? Though commonly misidentified as dirt, fungus, or mold buildups, black streaks on asphalt roofing are actually caused by algae. Although it poses no real functional threat to your roof, algae may ultimately decrease your home’s curb appeal and reduce its resale value. Platinum Roofing & Renovation of Richmond, KY, wants to help you understand and prevent black algae stains on your roof. Here are a few helpful pieces of information.

New Roofs Are at Higher Risk

Approximately five years following the installation of your new roof, you may begin to notice algae discoloration on the asphalt. This is especially true in humid and rainy climates. The increased use of filler materials in roofing products, such as limestone rather than petroleum materials, is usually to blame for this. These fillers, which are so common in new roofing, tend to facilitate the growth of algae.

Use Care When Cleaning

roofingAlthough power washing and cleaning products are typically effective when it comes to cleaning asphalt roofs, the algae will most likely grow back in time. Additionally, continued use of harsh cleaning methods will deteriorate and degrade your asphalt roofing. The best way to treat algae stains is by using a spray solution of water, bleach, and trisodium phosphate, which is less corrosive to your roof and better for the environment. 

Invest in Algae-Resistant Shingles

The most effective way to get rid of algae is by investing in algae-proof shingles, which may necessitate reroofing services. Algae-resistant shingles contain copper filaments that prevent your roof from retaining enough moisture to foster the growth of algae. To know for sure, contact your local roofers and ask them if your home is a good candidate for a new roof installation with copper shingles.
