Have you noticed black streaks on your roof? While it may be alarming, it is pretty common. However, that doesn’t mean that you shouldn’t do anything about it. Those dark marks on your roof are a sign of damage that is to come. You should get started on getting rid of them as soon as possible.
Below, we answer common questions about black streaks on your roof and how to get rid of them. We provide an explanation of what those dark marks are and how you can protect your home and household from their impact.
Common Black Streaks on Roof Causes
There are various possible causes of dark marks on roofs. Some of the most common include:
-
Algae
Algae is amongst one of the most common causes of dark marks on asphalt roofs. The dark marks occur when the blue-green algae develop a dark, hard outer coating.
Algae feeds on limestone, which occurs in asphalt. They therefore weaken the asphalt shingles and cause their premature aging. Removal of algae is also important to prevent rotting of shingles.
-
Dirt
Roofs can become stained when dirt and debris collect on them. Dirt and debris can cause stubborn stains. They can also act as water dams, causing water to collect in certain areas of the roof and causing rotting or penetration through the shingles.
-
Mold and mildew
Mold and mildew can also cause staining on roofs. A mold infestation can grow during rainy or humid seasons. This is especially true when your roof has debris, dirt, and algae. The growth of mold and mildew promotes rot and compromises the integrity of the roof. Mold and mildew are also a health hazard to your household.
How to Remove Black Streaks on the Roof
If you have dark stains on your roof, you may be wondering how to get rid of them. The best way to remove these dark stains is by engaging a professional roof cleaning contractor. This is important not only to ensure that the roof is cleaned thoroughly but also for safety. There is a high risk of falling while cleaning. It is important to ensure that you not only have the right equipment but also the right kind of knowledge and experience to work at heights safely.
Another risk of cleaning the roof on your own is that you may end up causing more damage to the roof. Many homeowners, for example, opt to power wash the roof. This results in damage to the shingles as well as penetration of water into the inner layers of the roof. Repairing damage to shingles can be expensive. The roof may develop a mold infestation or rot as a result of the water damage to the inner layers and the roof.
Professional contractors apply soft wash roof cleaning techniques that prevent damage. They also apply the right chemicals to treat and protect the roof in the long term. A professional cleaning contractor will also examine the roof to identify damage and may be able to provide repair services for minor issues. They will alert you to any issues that need your attention.
Regular cleaning of your roof can help prevent future black stains. You should also look into installing a strip of zinc or copper metal on the sides of your roof ridges to prevent the growth of algae.
