new rig?new guy? need help plz

Recommended Posts

I have been around the roof cleaning only service for sometime now and all I have used is 12v pump system. That is not to say other systems are not good also. Personally I like the no noise with a 12v pump system.

I don't own a pressure washer so don't have to deal with such on that end either. If I was going to purchased a roof cleaning or no pressure system I'd go with the fatboy bandit from Bob @ Pressure Tek.

That's not to say other systems are not good but, in my opinion, it is the best bang for the buck.

I can shoot three stories from the ground with my pump. If you know how you can set the pressure higher and shoot even further.

The only issue that you may have with a 12v pump or Fatboy pump is the relay switch overheating but that is an easy fix by using a solenoid to replace the bypass switch.

98% of our work is cleaning wood/cedar shake roofs which requires a lot of pump time because of how the cleaning process works.

We clean on average 75 cedar shake roofs a season, only because we do this part time, and I have cleaned about 150 with my present pump and still going.

With your budget you should be able to set up a nice system. Though make sure to save some for marketing purposes. Starting out that will be a big cost.

Just to clarify. I don't shoot a roof from the ground, from ladder. Just pointing out the distance possible with the Fatboy 12v pump. I tested with water.

Yeah I fig as much.. With my luck id kill a whole grass field trying to shoot from the ground.. We don't mind using ladders we are still young so its good for the body :) I just want to be able to tackle some commercial jobs like fire dept, churches, apt complexes and I dont want it to take days or weeks to get it done. But everyones help as been so helpful.. the fatboy bandit setup like you have seems pretty legit for a 12V system and has everything you need besides a tank.. needless to say the wheels are spinning and spinning...

From a business stand point consider this.  If you get to the point where you're like, "Ugh, not ANOTHER 3 story 6000 square foot house.  That's the fifth one this week.  Man I wish I had gotten a 1" pump setup." you're in the best possible and most justified position for an upgrade.  The other setup, regardless if it is 1/2" air or 12v will still be a great backup.

Matt thats a good point.. I think we are going  to target the high end homes and most are 2 stories with a basement so 3 stories 40 ft in the air and a ladder will do the trick but damn it sure would be nice not having to move the ladder 100 times... thanks for the advice man,

That's a very good point, Matt. I like that thought process. Better to have too much work and justify the upgrade rather than have the upgrade and not have the work to justify it. The 12v would definitely be a good back up or use for another rig setup that can be used for a different 2 man team if we do upgrade. I know I'm getting ahead of myself with that one, but a man can dream, right? Lol.

So many decisions! Aaaaaaghhhh!

we ditched the air setup because for one its noisy, you have the pump clicking non stop when using it, and the compressor running. you have the gas in the compressor and oil changes as well.. Also, lets say your spraying the roof, come down the ladder and the homeowner is wanting to chat, you can set the 12v hose down and talk, where as the compressor will just keep running in the background.. There was no real benefit for us using a air pump over 12v...  If your doing 4, 6,000 sq ft roofs a week the only thing you will be complain about it how many trips to the bank you will have to take. Never will you be saying oh I wish I could shoot 25 gallons a min of mix onto the roof and flood it out...   Sure, rinsing for moss with that pump would be great, but you may not have moss?

I LOVE noise. Brings the neighbors out to see what you're doing. My compressor idles down when it reaches 150psi, and only uses 2.5 gal of gas if it runs continious all,day. Usually I have to screw around a little so it takes longer than 15 minutes to spray a 2500 sqft roof.  To each his own.

good point made me laugh. I agree 100 percent and no I don't see many roofs that have a jungle on top. 12 does seem solid I can't knock it. But I planned on doing this fire house really big roof maybe 6000 to 8000 or churches.. Can a 12v system do this from time to time? Most houses will be ranch and 2 stories  (we will be practicing before we tackle a job)

Something to keep in mind with all this added flow that others may tout when it comes to these huge air systems. There is a limit to how much you can spray on a roof before it becomes an issue for serious amounts of runoff,..not to mention waste. So,.there is a "saturation" point on flow,..(Pardon the pun,Ha,Ha,)...The advantage to air isn't so much the flow or speed,..both can be handled effectively with a 12V like the Fatboy.  For me the advantage is, air pumps come in superior materials when it come to resiliency to SH,..and can also spray with any nozzle,..a 12V needs the addition of an accumulator to do that,..which isn't a big deal I suppose.

Seems like there's been a big push lately for these big air systems,..mostly from this site. These big air systems with 3/4" hose aren't at all necessary to do this work VERY effectively and be a professional.   I use a simple wheel barrow compressor and a 3/8" All-Flo and 1/2" hose. .works very well and is big enough to do commercial work when needed. As I said, there's only so much flow a roof can handle before it's too much flow ,..so don't be sold on crazy flow rates and speed,..

*If you want  more unbiased information go visit The Pressure Washing Institute forum,..lots of information there on both air and 12V.  

**Being able to spray a roof in 15 minutes isn't a goal you need to be concerned with,..if you do that,..you will be dealing with alot of runoff,..which amounts to wasted material and potential landscape issues. Nothing wrong with being on a job for an hour or more. 

***Years ago,..many guys were using 1.8 GPM  Shurflo pumps with 3/8" hose  and making money,..Not the way I want to do it and the roof cleaning options are way better now,...,..but the point is it can be done effectively with far less flow than we see today. There is a broad range between 1.8 GPM and 20 GPM,..so pick your method and make some money. 

****Flow equates to shooting distance,.which equates to safety,...so whether you go air or 12V keep that in mind. Usually 35'-40' is  enough for what you'll need and the Fatboy or the All-Flo will get you that.

hey Jeff great post and really brings to light a few thinks we never thought of.. I think no matter what half the people will say air and half will say12v.. But I do think just starting out 12v might be the way to go and prevent us from over spray ect...

Regarding runoff,..you can use any pump you want,..runoff is controlled by the user more than any other factor. Very easy to want to keep spraying,...but in reality you want to spray and let the flow take over,.. and sit and watch a minute or two,....soon enough you will learn how to determine and limit runoff.   Air is nice for this type of flow control,..because you can nozzle down without the pump having an issue. Many guys go 12V though and just accept the small learning curve of application. 

*Alot of guys still use the Delavan 5850 5 GPM pump,...that may be an option in the 12V as well.  From what I've read over the years they are a pretty decent pump with less flow than the Fatboy,... and shoots 30'-35' ft,...and are only like $130.00 or so.

thats 20k sq ft

dang thats a lot of roof. We had a meeting yesterday and its been decided that starting out we are going to run a 12v system. So at least our minds have been made up. We were talking about doing the bandits in a box from pressure trek and then all we need is tanks and we should be good to go after all the little small stuff.. Now time to bargain hunt I am Assuming this stuff never goes on sale but I am sure maybe we can find some good 2nd hand stuff.

Thanks again everyone for the help.

If I were you,..I would look at a 12V system and simply put it together yourself. These pre-made units are fine,..but not needed and over priced in comparison to DIY,...with the same end performance,..and also a knowing of how a system is put together,..great for troubleshooting in the future. 

Rigging of 12V or air is very simple,..those boxes are nothing but battery boxes you can buy locally. Aside from that it's a pump, battery, hose and clamps, and trigger valve,.I wouldn't pay extra for this stuff as a kit,..when it's so simple to begin with.

Also,..Kuri-Tec hose is the best roof cleaning hose you can buy,..cheap and high quality,..seldom those two things go together.

Hey Jeff first off i just wanted to say THANKS SO MUCH for the advice.. I wanted to make my own system because it does seem easy but with the box set up he talks about a pressure switch and wiring all done for you. That's the only part I was not sure how to do so I thought if I bought the box system I could just lean how to do it that way and then for the future know how to do it, however I am sure with a little research and the right questions I could prob fig it out my self.. This is the link of the system we were thing about but when I priced it out separately I think it was about the same price if i built it myself but I could be miss lead. http://pressuretek.com./defakuteckit.html that the full link its 606.37 for the fatboy nozzles, kuriyama hose ( is that kuri-tec?) and then just hoses.. I am all about saving money just not sure where to look or what to get 100%.

The pressure switch is on the pump itself,..and always comes ready to go,... you're thinking of is actually the on/off switch.  Which he just uses a typical light switch like what's in your home, and a waterproof box,...all things you get locally.  Very simple to wire,..simply cut the hot wire and simply attach a common 30 AMP or larger switch between the two leads,..not hard at all. (Some people actually use the ground to wire the switch into,...Not sure why?     Yea,..if the cost is close then not a big deal,...but if you ever watch Bob's video on wiring these units,..not that impressive,...he uses rudimentary connections like crimping,..instead of  soldering,..which is way better and trouble free,..makes solid connections.  Not sure why he doesn't do it properly,..or maybe now he does?

*Yes Kuriyama is Kuri-Tec,..Not sure what he sends with the kit, but what you want  is k1154,..this would be the red,..K1156 is the blue.

Hey Jeff I am not sure what hose he sends its a kuri tec but its yellow its a 600 psi AG hose with stainless ends...  I looked the up red and blue hose they are rated at 300 psi but I dont think it matters since its a 12V system.For a 12V system would you do 5/8 or 3/4 hose? I guess Ill call kuri tec today they do not list prices on there website and it seems it only comes in 100ft 300ft or 500ft so I guess I could hook 2 100s together to make 1 hose? or maybe They will make whatever size I tell them If I call and then just buy the fittings. As far as the switch I think your right it does seem pretty easy I mean there are only so many ways to do it I guess I cant really jack it up to bad haha.

Thanks

300 PSI is plenty for either air or 12V. If you were around 6-8 tears ago,..you'd see that it was the hose of choice. That 600 PSI hose isn't near as flexible as the 300 PSI Kuri-Tec,...It is still used by many contractors.  I wouldn't use neither 5/8" or 3/4" ,..I'd use 1/2",..lot of debate on that,..same as air vs 12V discussions,..some say 1/2" is plenty and others say 5/8" and 3/4",..but years ago I think the overall consensus was that 1/2" was all that is needed.   I did the 5/8" years ago,..found it not beneficial enough. 

*You really need to explore other sites,.LOTS of info you'd find useful.

**Pressurewasherproducts.com is the place to buy Kuri-Tec,..comes in 200' and you can get your ends of choice,..size and material. There not as fast shipping as others,.I've heard about their service being bad by some,..but I never had an issue.  I think many still shop there,..it's where I bought my All-Flo and Kuri-Tec. Better yo call them though.

Over the years I have bought a lot of stuff from Bob. As to fatboy pump best price is http://www.pwmall.com/p-133794-7870_101e-delavan-fb-2-diaphragm-pump-12v-60psi-70gpm-dem.aspx . I also bypass the relay switch by using a continuous solenoid .

On the same page for the pump is a heat shield at the bottom of the page which works great. FYI

Ok..so let me provide a counterpoint arguement in favor of air. It is no secret I am an air pump fanboy and I rebuild and sell them,so yes I am biased. But the question is...why?  

The entire epreason I purchased my first air system was the same reason I sell so many now....reliability. While there are certainly outliers, the vast majority of contractors who purchase air pumps from me are doing so because they have had it with electrics breaking. And yes, they rinse. I ran electrics for several years and we rinsed with religious fervor, ran 4/0 power cables, accumulators...and went through an average of 4 FB pumps and numerous relays and pressure switches per year.  This past spring I sold off the first air pump we used. It was still operating flawlessly and after a season with another contractor continues to do so. 

Flexibility. What a larger pump brings to the table is flexibility. The ability to shoot very long distances with effectiveness as well as put on large quantities of product WHEN NEEDED is what sets a large scale air system apart.

Economy. A larger Air system does NOT mean more runoff. In point of fact, air systems are capable of far lower flow than electrics because there is no pressure switch which limits how small a nozzle you can use. I can shoot a 1000 sq ft single story walkable roof with my 1" air and use less material than I would using an electric. In point of fact, our materials usage dropped by about 25% since moving to air. 

Long term investment. An air pump can be rebuilt. I have rebuilt AODD pumps which were 20 years old. After being rebuilt, they work flawlessly. Now this is no guarantee yirpurs will last that long...but I can guarantee that you won't find an electric being used for long term SH application over 5 years old. 

Noise...no getting around it, there is noise. But the added productivity is worth it and having a large air compressor also brings an added bonus...we are able to safely remove loose roof debris using compressed air. It is much safer to do this with a compressed air hose than a heavy air blower we used to take on the roof. This is only applicable with a larger compressor. 

Last but not least...cost vs price. Electrics have a lower price but a higher cost. Look at nearly any thread on electric systems and contractors who use them will tell you the same thing....have a spare pump,  have spare relays and pressure switches. Why? Because the electric pumps we use in roof cleaning are fundamentally not suited for the application which we use them for. They have fundamental flaws in their design which we, as roof cleaners use band aids and work a rounds to try to fix. But the fact remains that they were NEVER designed as high oxidizer chemical pumps, never designed for high head pressure, high lift applications, and never designed for constant on/off usage. The FatBoy was designed as a boat wash down pump. Air pumps were specifically designed for, and uniquely suited for this type of application. They are available in resistant or even completely immune materials. They are designed for high lift situations, and they are not flow limit restricted.

I agree.  And that's after using 12 volt for 20 + years.  Case in point this week. I cleaned the worst tile i ever seen in 30 years. It was a Classic Terrecotta Clay Tile.  Vacant house for the last 20 years. I put my normal mix a little more stout in fact and sprayed the worst area as a test.  It did not even phase the GM. Did not even lighten it a bit. I almost walked down and packed my sheit up.  This orange roof was as black as TAR and baked on for years.  I did something I have never done. ( Forgive me Father for I have sinned.)  Yes I ended up putting STRAIGHT SH on the roof. About 3 times before it broke it down.  And back to normal mix the next day to hit the dark remaining spots. You wanna talk about a homeowner in disbelief.  He still can't believe i didn't pull out the high pressure washer. Needless to say it would have melted 2 or 3 12 volt pumps to do that roof. Its about 7000sf, so I don't think I would have been able to run that much pure SH thru a 12 volt at all without failure and be forced to finish the job with pressure.  We are talking about 300 gallons after all said and done. He paid me an extra 500 and has agreed to pay us to seal it, because  it is so clean. Every time he sees me he says, "i cannot believe how good that roof looks."

Hey Kevin I tried to PM you but the forum wont let me sent it for some reason.. We are going with a 1 IN pump we got the air compressor already I wanted to see what you had or if you will be getting anything over the winter.. If you can PM me so we can talk details, Once again I am not sure why I cannot sent one.

Thanks
