About helping business, article from local paper. lDEAR TIM: Roof cleaning needs to be done at my home. I have a newer asphalt shingle roof, but parts of it are getting covered with moss, lichens and algae. It is really distressing as it makes my house look like it is being neglected. Is a pressure washer a great tool for cleaning roof shingles? Will it remove all of this growth? A neighbor told me a pressure washer would ruin my shingles. Are there other cleaning alternatives? Once the roof is clean, how do I prevent the stuff from coming back? —Tom B., Whittier, N.C. DEAR TOM: Welcome to the world of organic chemistry. I'll bet the north-, northwest- and possibly west-facing sections of your roof are the ones that look bad, while the remaining parts of the roof look like new. What's more, my guess is that the parts of your roof that are the worst get shade from some large trees. I know this, because I have exactly the same problem as you do. Parts of my roof look like the Amazon rainforest. Spores are broadcast by the wind, dropped from trees and delivered by birds to a roof surface. The abundant water you get from periodic rainfall fuels the growth of the moss, ichens and algae. Since the north, northwest and west sections of your roof stay in the shade during the early part of each day, the dew that develops on the roof at night does not evaporate quickly. This morning moisture quenches the thirst of the mini-vegetable garden up on your roof. The other sections of your roof dry too quickly and the moss, lichens and algae die of thirst. Like you, I have also heard urban legends about pressure washers causing permanent damage to asphalt roof shingles. I know for a fact that pressure washers can damage concrete, so it would seem plausible that they would harm shingles. But I wanted to try it just to be sure. Since I know how to replace one or more roof shingles quickly and easily, I decided to test my own roof. I figured it would be an especially good test subject since it is now 20 years old and at the end of its useful life. I also decided to test some new shingles to see if the pressure washer blasted away many or all of the colored granules. The shingle-cleaning test started with a gasoline-powered pressure washer that develops 2,500 pounds per square inch of pressure while delivering 2.4 gallons of water per minute. I equipped the pressure washer spray wand with a 25-degree tip. This tip is used for general-purpose cleaning. The results of the test were astonishing. I was able to remove all of the moss, lichens, algae and 20 years of dirt with the pressure washer. No damage whatsoever was done to the asphalt shingles. I started with the spray wand tip about twelve inches from the surface of the shingles and aimed the wand down the roof. I didn't get any noticeable cleaning results at this distance. But once I slowly lowered the wand to within 6 inches of the shingles, the organic growth started to disappear. I recommend that you carefully clean just one shingle, and then stop working and inspect the shingle for damage. Walk to another part of your roof where the shingles look great to see if the clean shingle looks just like the freshly cleaned shingle. Rest assured you will readily spot damage. If you see small or large patches of solid black or fiberglass mesh, you are ruining your roof. You can use a regular garden hose and a scrub brush to clean your roof. It will be an enormous amount of work, to say the least. Always point the garden hose or pressure washer wand down the roof. Never point it up the roof, as water can be driven up under the shingles, creating massive leaks inside your home. Once the roof is cleaned, you can keep it looking like new by installing strips of copper at the top of the roof. You need about two to three inches of copper exposed along the ridgeline. If your roofer had installed shingles that contained invisible copper-coated granules, you would not have to do any of this work. The slow release of copper on the roof surface prevents the growth of moss, lichens and algae. « Return to previous page

I have big gpm increse, with 200' 3/8" hose 4' pvc wand and size 15 nozle with one shurflo i had around 1 1/4 gpm , with 2 pumps i have around 2gpm To increse gpm i also have 150" 5/8' garden hose (home depot) i get almost 2 1/2gal whit that, its just more heavy and dificult to drag around.Its good to have diferent gpm's for diferent roofs.

(1gal chems+4gpm water , will bee 20%chems in mix).Ordered Adams 20% adjustable injector.Tested with 4gpm,3000psi machine,3 feet wand,black soap nozzle,75 feet high pressure hose,injector open allway.To draw 1gal from bucket thru injector I needed 2min. 10sec., that's makes 8gal water to 1gal chems or 11,1111%.So I dont understand or the send me wrong injector or its at all is impossible to draw 1gal chems in 1min and get 20% draw with downstream injectors.If its possible what brand and where I can get them. And i did tested my machine for gpm , I am geting 4gal per min. Thanks for your help. Vlad.
