What Are The Black Streaks On My Roof?

Unsightly black stains or streaks on asphalt shingles are caused by a hardy type of algae called Gloeocapsa Magma. The algae feeds on the crushed limestone that is used in asphalt shingles. Rain spreads the algae down the roof causing the black streaks. These streaks are not only unsightly but cause the shingles to fail prematurely by not allowing the shingles to reflect heat properly.

 

 

 

50% Of Roofs Are Replaced Due To Physical appearance.

This is not because of their functionality.  Just as mold and mildew can grow on your vinyl siding, wind blown algae can land and grow on your roof. Replacing your roof because of this algae is like replacing your siding instead of having it cleaned; completely unncessary.

 

Some contractors may be aware of the algae growth but instead tell you that it can’t be cleaned without damaging the shingles. Regardless, they may tell you that the roof needs to be replaced. This is not true if your shingles are still in good shape. The algae can be killed and removed properly without damaging the shingles using a low pressure cleaning process.

 

 

Roof Cleaning Is Recommended By Shingle Manufacturers

The Asphalt Roofing Manufacturers Association recommend a low pressure chemical application using certain cleaners to restore shingles suffering from roof algae, followed by a low pressure rinse. ARC applies these methods for a safe and damage free roof cleaning. If your shingles are still in good shape but have roof algae on them, having your roof cleansed will allow you to get the full life out of your shingles, saving you thousands of dollars.

 

 

Signs Of Aged Shingles Needing Replaced

We do not recommend cleaning shingles that are in need of being replaced. If you’re not sure if your roof needs to be replaced or cleaned, here are some signs of an aged roof:

1) brittle or crumbling shingles
2) excessive amount of shingle granules in your gutters
3) bottom corners of shingles curled up
4) wavy, warped, or heaved shingles
5) very thin or loose shingles

 

If you are still unsure about the status of your roof, we will be glad to evaluate it for you. We will not clean shingles that need to be replaced, because cleaning the roof won’t solve the problem if the shingles are aged. Keep in mind if you're call a roofing contractor, you'll most likely be persuaded into replacing a roof that may only need cleaning.
