@racer we started typing up a guideline and got held up on the 5 year streak free guarantee… The organic growth is usually visible after the second year; no matter how perfectly it was cleaned. How does one honor such a guarantee. I was thinking of making it a two year streak free guarantee, because this seems to be the period time we could be liability for our cleaning and not Mother Narure’s natural growth.
You can put what ever you want. That’s just what most have down here, though I don’t really advertise it, because if heavily wooded it may come back sooner. About 5-7 years is usually how long before it comes back though.
Also, the warranty is only if we do the whole roof. 95% of my roofs are partial so warranty doesn’t come into play.

Have you been washing roofs for 2 years? Where does this info come from

Thanks

@Firefighter4hire - In all honesty, I do not have two seasons of roof washing yet and there are so many variables affecting the individual situations. Do you have anything productive to mention about shingle roof organic regrowth or guarantees?
Just added something to my warranty info, see above.

Ive only been in it going on two years but I think here is Louisiana we have some of the worst climate factors considering organic growth rates and I haven’t seen anything come back that fast. Time will tell but I think you’ll be safe offering 2-3yr warranty under the worst conditions. In the case that it comes back do a quick spray of 3% on the problematic spots and let the rain do the rest.

5 years is what I guarantee. I ask because I’m curious didn’t mean for you to get defensive. We have talked about this in other post. I was under the impression that you hadn’t done many roofs. I was curious to know who was giving you this advice or if it came from experience based on your other post aking about roof cleaning

@Firefighter4hire i just kinda pieced everything I have heard, learned and knew then roughly estimated about two years. I still am unable to get my mind around how a shaded shingle roof could possibly not start regrowing under the same conditions within 5 years. 5 years is half a decade lol, our faces would have aged in the mirrors how would I be able to keep a guarantee of moss not growing in the same exact spot under the same exact conditions. There must be some piece that I am missing. I plan to offer a two year guarantee along with comment that the should be good years longer.

Do you think the original moss formed in less than 5 years. I would bet you that you are cleaning roofs that are older. At least in my part of the world it takes much longer for it to form this is why you can offer that. What are other compa8in your area offering. Kinda the same concept it took many years for it to form it will not go away in 2 days.

When a customer asks how long it will take to grow back I play it safe and say 3 years for sure but probably at least 5 or 6 years.
I know anything that comes back in 3 years (if it does) I should be able to just hit with a pump up sprayer and keep the customer happy and cost me $5 $10 bux to fix.
Pretty much tell them the same on the house washes.

Mold and mildew is likely growing back after a few weeks not five years. Its just that its not bad enough to see yet and will probably take about five years to get that bad.

Everyone has their system. I rinse every roof. I apply it and let dwell until brown. Re-spray stubborn areas and more dwelling. I rinse twice and tell customer that rain will continue to rinse. They’re happy because they see immediate results and I can see that I didn’t miss anything. IF they ask, I tell them that it should last three to five years, depending on rain, trees around house, humidity, pollen…etc. only been doing it for two years but no call backs so far. Rinsing takes the longest but in my opinion, well worth it. It would take me 30 mins to spray a 2500sqft roof and almost 1 1/2 hr to rinse twice…collect $500 and I’m out!

Dude. You don’t have to list your business name and location on every post. You’re going to keep getting flagged until you stop doing that.
Just letting you know who said it and what experience I’m speaking with. Sorry. Didn’t think I was advertising to other pressure washers. My apologies.
No worries amigo just letting you know.
It’s good for SEO though but would clutter the forums. Complete your profile and we will see who said it.
This is amazing info. Thank you
I really don’t understand the idea of not rinsing the roof down after the chemicals have done their thing. It comes off as very lazy, a very lazy approach. You guys don’t want to hear that, but it’s the truth. Furthermore, doesn’t the customer deserve some satisfaction after spending a cool grand for you to bleach their roof???
It’s just an odd approach that seems to be filled with justifications.

Did you want help understanding the reasons some people don’t rinse, or were you just wanting to tell them you think they’re lazy?

What exactly are the reasons? Do the reasons justify the roof looking like crap for a month? It seems like if you can rinse the roof off, then it’s a much more appealing process.
