Hello everyone, first post here after a night or two reading a couple posts. Going to say this first, I am very much new to this line of work with no firsthand experience, and all of my current understandings are sourced from YouTube videos, reddit posts, and probably only around 4-6 hours of research solely on this community. I am very interested in starting my own pressure washing business.
Basically, I wanted to know what your guy’s thoughts were on me servicing a roof for my very first client given my current experience/knowledge/conditions of:
Only have used a electric power washer for my own use on cars, patios, 1-2 wooden decks.; pure water. 1.6 GPM and 1600 PSI.
Researched YouTube, Reddit, and pressurewashingresource.
Off the top of my head, a few channels I’ve watched on YouTube are Forever Self Employed, How To with Doc, Aaron’s Lean & Mean Academy, and Kyle Maguire with United Soft Wash. Reddit Advice #1Reddit Advice #2
The homeowner is letting me use his pressure washer, no idea what model and make, just 3.2 GPM and ~3000 PSI, has the chemicals necessary already, and DS injector system. Client told me he has pretty much everything I need for the job, he just doesn’t like heights at all, so that’s why he contacted me after he saw my posting on Facebook Marketplace.
Clay tile roofing.
No license, just trying to side hustle until I can afford my own equipment.
Only servicing the first story of client’s home.
I’ve had to watch videos how to operate a gas pressure washer 
, check fluids of course, run water through washer and purge any air within before starting. Fuel valve open, close choke, throttle set, start (while holding trigger?)
Service gutters before attempting to soft wash the roof
Only things I’m bringing for the job is my 12.5 ft ladder, safety glasses, gloves, bucket, chemical sprayer, cleaning solution and a scrubber, and a mask to avoid breathing in SH.
Just in case the client does decide to get the gutter brightening, or if any missing equipment. Oh and I will be bringing a helper.
Soft wash roof bottom to top
Avoid having to walk on the roof at all costs, pre soak plants and continue doing so throughout job, decks, any dirty concrete on the floor to avoid clean streaks. Get a mix of SH, surfactant, and water, around 4% SH for roof, depending on condition? I have no current picture of client’s roof, no mold/algae was spoken of when roof was described. Spray mix onto roof with low pressure, let it do it’s work for a few minutes and little sections at a time, then rinse with low pressure and repeat if necessary. Check gutters for run-off and done.
Check surroundings and downspouts, apply water as necessary.
I’m probably forgetting to include something, so I’ll edit in anything if I remember, but please let me know what your guy’s thoughts are on this. If I’m missing anything, stupid, advice, or if my information gathered is invalid, anything at all.
I already tried explaining to the client that I was not experienced enough to soft wash his roof, but there was some language barrier and he still thought I was providing that service, so instead of denying the job, I researched for a couple days.
The job is supposed to be this Friday morning.
Should I take the job, or should I wait until I am more seasoned. Let me know, appreciate it.
Here are the images of the home I’ve gathered from Google.
