hey Im about an hour away from Boston, not sure where franklin is. You said a small job, if its really small ill probably pass but you can let me know. Im not sure how to use the pm.

black streaked roofs you can clean from the gutter, as long as your pump will push the chem. to the top of the roof. Roofs with algae and lichen (green) will need to be rinsed close range to make them detach from the roof( using no pressure) so you'll find that walking the roof will be the best...

I use a garden hose to rinse off the lichen. It is time consuming. But $400 for 6 hours of work is still worth it in my eyes. However, it does still take of some granules but, these are the granules that the lichen are rooted to and I'm not sure but, I think they'll end up coming off no...

Hi, Im not Don but Ill answer you anyways. If the mold is just black, all you have to do is spray it from the gutter and let it sit then rinse from the gutters. Theres really no need to get on the roof as long as your chem pump can reach the top of the roof. that stuff just disappears after...

I always have a groundman with me at $10 per hour. Every job, no matter how small I always bring him. This house is different because there are no gutters and even with a groundman, I'm worried about the plants. Some are telling me not to rinse but my job is to get the algae off the roof not...

Maybe the Florida market is different, but I'm in New England. Do you guys mostly do black roofs? Those I can see not rinsing. But, a lot of the roofs I do have the green moss/algae spores that turn white after the chemical application and stay stuck to the shingles for a LONG time afterwards...

So, do you guys think that with enough dilution I should be OK? Even if I add soap for cling, all of the chemical is gonna come down when I rinse the roof anyways but, it will give me time to dilut the bed.

Hello everyone, I got a call today for an estimate on a house with no gutters. Not just that but, the roof is really steep, pretty dirty, and surrounded by plants. I use a 4% sodium hypo mix with some TSP. Now, I know this will kill the plants or at least do them some damage if I just let...

anyone have any suggestions for some of the cheaper pumps some use for rinsing the roof after chem. application. A lot of the customers I serviced don't have good enough pressure at their spigots and I'm looking to buy a pump that will give me better pressure than a garden hose to pump out my...

A lot of the other (non chlorine) mixes need to be rinsed off with some pressure applied or else they have to sit for a really long time before effectively killing off the mold. I myself have never used them but this is what I've heard. A lot of them are only trying to make money by using...

If I remember correct for 100 gallons it's 30 gallons of 12.5% SH (liquid shock), 12.5 cups of TSP and 12.5 cups of Borax and 70 gallons of water. I've been using about the same but, without the borax and it's been working out great for me.

The Applesauce is just SH with some TSP and Borax

I'm looking for 2 hose reels that I can use with my polybraided 1/2" chemical hose for roof cleaning. I'll need at least 200 ft. capacity for 1/2" hose. Shipping isn't a problem.

Hey, I've got my roof cleaning setup up and running and have done about ten roofs so far, but my problem is getting organized. I've made my startup cash back so it's time to start buying the rest of my equipment. I plan on mounting 2 hose reels to a trailer. One to run my poly braided hose for...

Anyone know how to get the exact sodium hypochlorite reading from chlorine on your own? We all spend a lot of money on this stuff and I'm wondering if anyone knows how to measure it on your own without taking the stores word for it. A store in RI was fined $10,000 for diluting their 12.5%...

i agree. this is my first year in business and i am already booked up for the next 3 weeks. I know that doesn't garauntee a good season but it's definitely a good start. if you keep your head in the game and stay hungry for more work, you should do good.

Well, my first season as a roof washer is starting off pretty good. Hope all is well for you guys too. So far all the roofs I've done have been on houses with vinyl siding or painted wood siding. My question is how to clean (if I should attempt it) roofs on houses with natural wood siding. I'm...

A $450 minimum!? That's a good minimum. Do you get a lot of jobs at that price.

Chlorine is an obvious one. Other than that I'm not sure.
