Do the stains on my roof matter?
Now that the temperatures are up and the sun is out longer you may be able to see life differently.
One of the things you may see regularly is the condition of your house as you pull into the driveway.
Your roof and siding may look dirty due to algae.
Where does the algae come from, and should you be nervous?
On many roofs the algae appears to look like dark patches.
Sometimes it appears to look like the fungus you might see on a tree or rock in a wooded area.
The patches or fungi are actually blue-green algae called “Gloeocapsa Magma.”
This algae is usually found in humid, tree covered areas and are spread by airborne spores.
So, is this algae bad for your roof?
It can be.
As the spores accumulate on your shingles they begin to thicken into a moss-like algae.
This moss-like algae will begin to retain moisture causing the growth process to accelerate.
In time, this algae could grow under the edges of your shingles causing them to raise the shingles up.
If you have significant life left in your roofing shingles, you may decide to treat the shingles to remove the algae, but be careful not to damage the shingles with chemicals or pressure washers.
If you are thinking that your roof needs to be replaced due to the age of the shingles, you may want to do some research on the shingles you are considering.
Today’s major shingle manufacturers all produce shingles with a coating that resists the Gloeocaps Magma algae.
