Mushrooms on roof November 08, 2020, 06:22:55 pm Well, maybe not mushrooms but certainly fungi? I put the eternabond on about 8 years ago. Never had a leak but I decided to clean roof and noticed the beginnings of a fungi garden. See attached picture.I am trying to avoid removing Eternabond if possible. I am thinking of cleaning with a brush and soapy water then wiping with a light bleach solution but I don’t want to apply any thing that might damage. Any one have any thoughts?
Re: Mushrooms on roof Reply #1 – November 08, 2020, 08:09:39 pm Since you have not indicated your location, I'm guessing you live in the PWN or some other place with a wet climate.Your roof has algae, common among LD owners who rigs live outside where it stays wet for long periods, such as in Oregon or Washington. Soap and water, along with a collection of scrub brushes and a lot of elbow grease will remove the algae. There are other cleaning methods that I will let owners with this problem tell you about.It's a problem we never face in SoCal, along with winterizing (higher altitude residents excluded).Larry

I was not there long enough to fully test it out but I can tell you bleach doesn't prevent it from coming back.Jane
Re: Mushrooms on roof Reply #3 – November 09, 2020, 04:18:41 am Hi Jack; I get that same stuff on my roof. I believe it is dirt that collects, and the plants (in this case brown spongy stuff) grow on that. If the eternabond wasn't tightly down it will grow under seams. Bleach is chlorine based and will evaporate in just minutes. There may be cleaners that will leave a toxic (to the plants) film, but if really clean the plants won't grow on the eternabond. I also get green moss on the down hill side or corner of my solar panels. Condensation of dew on the cold glass keeps it watered. I do clean my panels every few months, the ammonia in Windex, seems to keep growth down for a while. It's really the dirt that collects and stays damp and encourages plant life. RonB
