We use these pumps in our trailer set up.

Nice deal there Samuel! Remember your total combined liquid bleach should not go over 119 gallons while traveling.

Also, if you reach a point you need to buy other tanks a lot of guys recommend going by the Tractor Supply Store or Agricultural Supply stores because most sites charge an arm and a leg for shipping. I found most sites that the shipping was more expensive than the tank itself. I did find a site called www.SprayerDepot.com that had good prices on tanks and excellent prices on shipping. I was able to have a new brand name tank delivered to my door for $6 less than picking it up locally at the Tractor Supply store. They also custom cut their straps out of aluminum so if you need to add straps the code is 50STR for the 50 gallon tanks, 100STR for the 100 gallon etc. I only say that because the straps are not easy to find without knowing the code up front. They will install the bulkhead fittings for free if you purchase the fittings through them as well.

I'm just getting started really myself and even if you are on a barebones shoestring budget, at least spend the money to get through the "Plants & Property Protection" module that AC offers. The information contained in that module is going to give you most of the ways you can harm the customers plants and property that AC found through 50,000+ roof cleanings that you really cannot afford to learn on your own. You could put yourself out of business before you even get started trying to learn on your own. I was skeptical myself until I did the training and it was definitely money well spent, and that is coming from someone on a tight start up budget too. The next two items you'll need would be the Green Wash and Plant Wash, and Bleach Wash and Terra Wash after that.

Why 5/8 hose that is too big for 3 gpm.

 Eric Owens made another great point for using 3/8" hose vs. 5/8" hose - lugging around a larger hose means you're lugging around a heavier hose that carries more softwash mix, making it even heavier.  Not being a young 20 year old anymore, after a full day of physical labor cleaning a roof(s) out in the heat, the extra weight will make a difference. 

That's a PW tip you've got on there. Even with the 5 gpm pump you're getting it's only 60psi at the pump. through 200" of hose you're probably going to be down to 45-50psi by the time you get to nozzle. You're just going to get a dribble out of the pressure wash nozzle. Plus you'reDo like Troy says and get a softwash nozzle set or if you're trying to get by on the cheap, just get one of those $3 metal nozzles from Home Depot and put on the end of your hose. If you rinse it after every use you'll get several months out of it at least and distance wise you'll get within a few feet of any other nozzle.

Most of us use a 1/2" hose unless you've got a more powerful and higher flowing pump. You can try the 5/8 once you get your new pump, it may work ok for you. The 5gpm 60 psi is going to be about the same or just a little better than the average homeowners water pressure and flow.
