The roof is not walk-able, so we would need to clean the stains just by spraying and rinsing. Can I use my x-jet or do I need a roof pump? We are just cleaning the front of the roof which is visible in the video, what would you charge if you really wanted to get it?
Bump
Alot of the manufacturers of the roofing products, tiles shingles etc void the warranty if you pressure wash, just a heads up. The xjet works good. Normally when cleaning roofs such as spanish tile we will charge double that of a window cleaning bid. So if you normally bid 10cents per square foot or whatever you charge just double that. On two stories I will add another 100.00. So an example of a 2000 square foot two story house should be around 500.00 bucks for the roof cleaning.
Once again I don’s speak price but simply double your window cleaning price and it usually works perfect for a roof cleaning price
I’m concerned that the x-jet will dilute the chem too much and the roof won’t come clean without pressure, which is not an option for me. Anyone else care to weigh in?
You need a roof pump. No X-Jet.
Don’t do half a roof.
I don’t have a clue how the price of window cleaning would relate to the price of roof cleaning.
Double the window cleaning price?
I will PM you what I charge here in MS.
Definitely need a roof pump, as Thad mentioned x-jet will not work. Also be sure and water everything down VERY good, and protect those plants!

One of those “newbie” questions from me along the line of this roof clean question posed by Larry. Why could you not set up a low PSI pressure washer (2500-3000psi) with a hose barb (such as I’ve seen Micah from SC do…I probably TOTALLY missed something!!) on the end? This seems to be another approach to a soft wash without having the additional expense of a roof pump. Seems like you could then work off of ground level & maybe have to put an extension ladder up to reach some of those points on the roof. Could you not use an extension pole with a hose barb on the end? Is it because the chemicals are diluted with water & you will not get the full strength of the chems? Glad you brought this up Larry…I have 3 roofs I’m looking at now!
There are several reasons why you need a dedicated roof cleaning pump. One of those is you can’t get a strong enough chemical ratio on to the roof without using a dedicated roof pump. Another reason is control; you need to be able to have better control of where you’re spraying your mix compared to a pressure washer soft wash.
Also, with my softwash(for home buildings), I’m using between 0-300 PSI. With roofs I’m using probably between 0-100 PSI. I would not use 300 PSI on a roof. All you need for a roof is typical garden hose pressure. You only need a delivery system for your mix, no pressure.
You gotta have the right tools for the job. There is some cost involved with roof cleaning equipment, but the PROFIT earned MORE then compensates for it.
BTW, my estimate would be over a grand to clean the roof properly in that video.
With the right equipment, the right 4 way, and a set of cougar paws, you could walk the valleys and shoot the roof. And I’m with Micah on the price.
Is that for whole roof or just the part visible in the video? I did end up investing in a roof pump set-up. Micah how long would it take you to shoot that roof? would you rinse?
I was simply putting in my two cents, no need to make an attempt to degrade me live and direct on the forum. Im simply giving an idea of how I do things and thats what a forum is for. Simply my formula man, no need to be disrespectful!
I don’t think he was disrespectful, Mark. He just doesn’t see a correlation between pricing for window cleaning and roof washing, and frankly neither do I. But if that works for you more power to you, thanks for sharing
In that case you ask what is the reason to charge double the window cleaning price, I have doing this a while and the formula makes sense. It is an example and that is it. I am here to buy equipment for my business and gain knowledge, not to bash peoples ideas and kiss butt
He didn’t degrade you Mark. That much is a fact, regardless of how you took it. He literally said “I have no clue how the price of window cleaning would relate to the price of roof cleaning.”
To say he insulted you is really ridiculous. And don’t say I’m degrading you.
By the way how many square feet is the house
You are not degrading me and maybe I am taking it wrong. I bid by the square foot depending on where the house is located demographic wise. I got this method of bidding through a pressure washing business operator here in San Diego who has been in the industry since I was in diapers and it works. I don’t bid by the window on residential so maybe thats where the wires got crossed, I bid by the square foot.
4,189
Yep, def not degrading you. I really respect what you add to the forum.
Interesting method of bidding. Not one that’s often used, I’d guess.
Typical bid for me on a window cleaning job is 10 cents per square foot if cleaning windows I would bid 420.00 on average, so on roof cleaning I would double that. A two story 4189 square foot house I would bid 840.00 plus a 100.00 adjustment for the additional story so around 940.00 for the whole roof. Another guy on here said one thousand which is in the same range as what I bid normally.
I know it sounds weird but it is a method that tends to work for me, thats all Im saying
Glad we can all get along again and sorry for jumping to conclusions, it is an easy to bid if over the phone and tends to be right on the spot,
