How can you remove moss from roof?
Go to your Hardware Store as they have some great products out
there for getting moss off the roof of one's house. One mixture
would be 1/4 cup of trisodium phosphate (TSP) and one quart of
household bleach in 1 gallon of water. Do NOT use a pressure washer
on composite roofs, as it can loosen the granules from the
shingles, reducing its lifespan by 3 to 5 years. Don't forget those
gutters! Be safe, and wear good runners or gumboots with good tread
to prevent sliding off the roof.
