Bleach and Water to kill mold or moss on exterior of house?

[yy4me]

Once every few years, depending on the winter and spring weather, my husband used to spray this solution on the clapboards on the lower sides of the house with northern exposure. With such a miserable spring and summer here, the green cast is back. I have the sprayer which holds about two gallons. I do not remember the proportions he used to use to remove this green stuff. I do remember that he hosed it all down with water when the greenish stuff was gone. Anyone know the amount of bleach/water to use for this job? I can do it but don't want to add too much bleach and effect the color.

Would appreciate and help.

BTW, I also want to replace the bottom row of shingles on an "L" of our house, the edges are in tough shape. Again I can do the work easily enough but how do I remove the bottom row? All the nails are covered by the next row up. Everything else is fine, just this row of about 20 feet.

Thanks as always.

1. Get a gallon of simple green

it works really well for that and is easy to use. You may want to use a broom or scrub brush with a handle.
Or just poor the gallon in yer sprayer bottle,clorox and fill the rest with water. spray than rinse with hose.

On yer shingles, you use pry bar, flat bar and carefully pry loose the row above the bottom row. Pull the top row toward the bottom out to you about two inches or so.Do not remove. Leave that than take yer flat bar and get under the bottom row ,pry it out without taking out the row above. Remove two or three carefully than insert yer new shingles under the top row than nail. You will renail the top row over the replacement bottom row. After you have done two or three ,you will get the hang of it> It's easy,really ! Ask at hardware store fer proper nails. Even a home depot guy can help you with that ! (You will find the things you can do with Simple Green Amazing !)You know a guy in Buffalo New York invented that stuff to help chean up oil spills in the Great Lakes ! Good old Buffalo !

Good Luck !

2. You're the best! Remember I mentioned all the small tasks I had

do here, I keep putting these two off because of lack of knowhow.

Bought a gallon of simple green to wash a ceiling, will convert it's use to outdoor. (seeing that I haven't done the ceiling yet)

That will be tomorrows job if we get our 6th day of sunshine this spring and summer. No wonder we all have moss on our houses in this neck of the woods.

The shingle instructions make perfect sense and I have the tools. Off to HD to see if I can buy less than a square of shingles. I need less than 20' running feet. Have galvanized nails that will do the job.

Thanks again.

3. Interested in how the simple green worked

We usually buy some kind of moss chemical stuff that we spray on the roof and exterior. It does a great job, but I'd rather use simple green if it works just as well.

4. Good Morning, The Simple Green worked well in the areas

where the green cast was light. I have a 2 gallon sprayer that I mixed a diluted solution of SG and water, sprayed it on, used the long handled car wash brush to wipe it off and rinsed well after. This was on the clapboard section. Looks fine now.

On the section of the house where I have shingles, I had a problem with SG. The moss overcast was heavier. I just finished replacing the bottom row of shingles but before doing that, I tried the SG on a section about 18' X 4" high. It worked on some parts, not on others. After trying, I thought the moss was just too "green" on the lower half so I decided to use the bleach.

Rinsed all the SG off and mixed a solution of about 1 cup of bleach to 2 gallons of water and sprayed that on. Green gone with light brushing. Again used the car brush but with the shingles, used vertical motion to follow the grain of the wood.

This has been a problem with the rear of the house since we bought it 40 years ago. Just not enough sunshine hits the lower part of the north/northeast section.

I am satisfied with both methods. If I ever have to do this again, I think I will use a light bleach solution. SG is fine but more work than the bleach.For this old Granny, that part is important.

Neither product caused any change in the stain color. It is still the same old barn red with no streaks. I did rinse well with heavy hose spray.

It was a quick and easy job. As to replacing the shingles...that is another story.
