Roof discoloration is a common issue that homeowners deal with at a certain point. However, it’s important to note that not all roof stains are a cause for concern. Some may be a sign of serious roof damage, but others are simply a cosmetic issue. Before you worry yourself sick, it’s best to identify the type of roof discoloration that you have and call a roofing contractor to help you fix it.
Discussed below are the usual culprits behind roof stains and what you can do to treat or prevent them.
Algae
Roof shingles tend to grow a certain type of algae called Gloeocapsa Magma, which typically creates streaks or patches of slime with colors ranging from blue-green to dark black. Roof algae aren’t necessarily harmful to your roof, and it can be removed using oxygen bleach or a solution of trisodium phosphate applied via low-pressure wash.
Rust Stains
Red or brown rust stains typically appear around chimneys. These can be cleaned and treated with oxalic acid, which is also effective in preventing rust. As long as you address the problem ASAP, you don’t have to worry about extensive damage or a need for roof replacement.
Water Stains
Water stains usually appear damp and they could potentially be a sign of a roof leak. Make sure to check your attic or ceiling below the roof stain and investigate for a leak.
Lighter Spots
If your asphalt shingles look lighter or patchy in some areas, you might be dealing with granule loss. This is normal for aging roofs, but it could also be a sign of damage if your area recently experienced a storm. Check your gutters for signs of asphalt granules. You may need to replace your roof soon.
