Black Streaks On Shingle Roofs
- • Black streaks on your roof are not dirt or jet fuel
• Roof algae start as dots, then take a cone shape
• Spores travel to nearby roofs and spread through neighborhoods
If the growth on your roof is left untreated the growth holds moisture within shingles, causing premature aging and rotting. All of which can lead to leaks and even needing a whole new roof which costs thousands of $$$$$$.
If gloeocapsa magma is left untreated it can turn into lichen, which is a type of moss usually seen on boulders and trees. It causes the roof shingles to deteriorate over time and can turn a roof with a 15-year warranty into a roof with a 5-year warranty.
Lichen On your Roof?
Roofs are often damaged by lichen, which becomes an extremely hardy pest and is very difficult to remove. If you have lichen on your roof, its time to have it cleaned!
If you peel lichen off your roof, it will leave a scar or divot. Lichen has fused to the granules on your shingles and peeling it off also takes the granules off, even if it is dead. Roof washing will kill lichen immediately. However, the dead lichen will remain behind for a number of wet and dry cycles before falling off.
Roof washing will not repair the divots left behind from the lichen peeling the granules away, but it will prevent any further damage from happening.
Roof Moss Removal
You may have moss growing on your roof without knowing. We see it often hidden under dormers or lightly growing between the cracks in the shingles.
Roof washing is a great way to get rid of moss and clean your shingles. It usually puts an end to any potential problems with roots growing under them, too!
After roof washing the moss dies and becomes bright white in color, outlining the shingles it was growing under. Once the moss is killed, so are the roots.
Remember, it is much better to have the growth killed and eventually the clumps fall off the roof than to have someone up on your roof with a power washer or scrub brushes loosening the granules of the shingles.
Improper cleaning may be more abusive to the roof than the growth.
