Black Streaks On Shingle Roofs
- The black streaks on your roof are not dirt or jet fuel, it is actually gloeocapsa magma, which is a type of roof algae.
- The roof algae start as dots, then take on a cone shape, and will eventually cover your entire roof.
- The spores even travel to nearby roofs and spreads through neighborhoods quickly!
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?
Lichen is a very hardy pest and extremely difficult to remove from the surface because of how strongly it is embedded into the granules on a roof. If you have lichen growing on your roof, then your roof is already being damaged and no more time should be wasted before removing the lichen!
If you peel lichen off your roof it will leave behind a scar, or divot. The lichen has fully fused to the granules in your shingles and peeling it off peels the granules off as well, even when it is dead. Roof washing will immediately kill lichen. 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
- Moss will root into your shingles and may push up on the edges causing a potential for leaks.
- Our treatment will immediately kill the moss, but it will take a few sunny and rainy day cycles to remove the moss roots.
- The moss can not immediately be removed without the potential for damage.
- The growth typically releases within 1-2 months. Our method will keep the granules intact that protect your roof!
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.
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. This is actually more abusive to the roof than the growth.
