  1. Thanks, were all fine and no damage at all to the home, cars and boat. This even made news in my wife's little country of Bulgaria. The phone started ringing early this morning from her friends there to see if we were okay.

    I'm just kidding about the lights. You know how they always get in the way when you're cleaning a customer's house.


  2. I've never dealt with Delco but have heard many good things about them. On the other hand I ordered 100 feet of hose Monday night from a well known hose distributer in the south. I hoped to have it here Friday so I could rig up another roof pump on the truck but I got an email from them on Friday saying my order has just been processed. What was happening all week to my order?

    I guess it doesn't matter anyways. I've been hearing in the news that the world is going to explode Sunday. Figures! I finally get my home paid off in April and now in May the planet explodes... just my luck. How come I wasn't told about this whole "planet ending thing" 15 years ago when I took a loan to build this house? I think I'll start drinking again.


  3. No trade secrets here, pretty common knowledge in this field of work. I'll cover some of the basics, that should get you started in the right direction. First thing is NOT to powerwash a roof, you will ruin it. It's going to take a little patience to clean it but it will be worth it. You'll want to coat the roof with a diluted mixture of sodium hypochloride (a very strong bleach). Some people will call it S.H., some will call it "Love", but it's just sodium hypochloride. It can usually be bought as 12 (or 12.5) or 15 percent strengths. Call around to your local chemical suppliers. Out here I have to fill out quite a bit of paperwork in order to be a regular purchaser or this chemical. It has to be cut with water; I use about 60 to 65 percent water because I buy the 15 percent drums, not the standard 12.5 percent. The next step is the most difficult... getting the chemical onto the roof. Most of us here (myself included) run special pumps, hoses and guns designed to supply the SH. This stuff will eat through the seals of regular pumps and destroy them in a matter of minutes. Be sure your equipment has Viton seals otherwise you will have to throw it in the trash as soon as the SH begins to flow through it. A bleach pump sprayer will work but I don't recommend it because 1) you can't get the volume of liquid needed onto the roof without spending all day on the roof. 2) It's not very safe spending that much time walking all over the roof, up and down the ladder spraying a nasty chemical. A couple different things are going to happen once the SH hits the roof. The black algae will vanish in a matter of moments and the green moss will turn white. This is good. When the moss turns white you will know it's dead, just give it time to allow it to kill the tiny roots stuck into the shingles. The last part is the easiest; wait for rain to wash it all away. Depending on how severe your moss problem is it might take several rain storms to remove it, (I've had roofs that have taken several months to clean). Watch for clumps of white moss at the bottom of the downspouts. Lastly, protect your eyes, your hands, and cover any plant life you dont want killed when the SH touches it. To be quite honest with you it might be cheaper to hire a professional in your area to do this for you. Rather than buying the equipment and chemicals (if you can buy the chemicals) for a one-time job it might be benificial to have someone with experience do it. For example I would charge about 150 dollars to do a small ranch style house. For that price the customer is getting my truck, my equipment, my chemicals, my time, my knowledge and a beautiful roof when I'm finished. It's a win-win for them. If you insist on doing it yourself try to plan it a day or so before a good rain storm.

    I'll add some pictures of roof that were sprayed on Saturday. I did them on Saturday because the forcast called for heave raid all this week and so far they have been correct. You'll see large white clumps of moss that were green just before the SH it them, you'll see black algae being desolved as the SH drips past it and you'll see the truck down below thit the chemical tanks, roof pumps attached to the front ladder racks and a extra drum of SH in the back. Well you should see these things, I haven't tried to upload the pictures yet. I hope this helps you. Honestly though, it might be cheaper and easier to hire someone that cleans roofs.
