I have my first metal roof coming up and a little nervous about it. Any tips and tricks? House doesn’t have gutters so I know the solution will run off quick. I plan to use a 60/40 solution with cling on. Should I increase the cling on to try and make it thicker for less runoff?
Read through the posts on the site, but no matter how much surfactant you use its still going to run off quick. Make sure your landscape is covered and watered down and I would dilute your mix more though.
I’m by no means a roof expert, but on 1 of 2 that I have done I used spring clamps and a tarp to make a “runoff ramp” to funnel it over flower beds and onto the concrete.
From the pic here it looks like that’d be simple to do on this roof too.
I have tarps for the bushes and shrubs. Would 60/40 be considered too strong because it will damage the grass more or cause damage to the metal?
You’re better off using a lighter mix, say about 3%, even if you have to hit a couple of times. Don’t let your mix dry and rinse thoroughly and then rinse again. I always hit with a bleach wash (bleach neutralizer) when done and that will need to be rinsed also. This one not that bad, so one good application should do it.
Thanks a lot. I’ll weaken if a little and see how that goes. Will try to do it on an overcast/cloudy day to help with the drying too fast issue, which won’t be a problem in south Louisiana with all this wet weather.
Let us know how it goes
Finally got around to this metal roof…it sucked!! Several coats of mix needed and took a lot more time than expected
Would citric acid work for the bleach wash?
I don’t know with regards to a metal roof. I would just rather use a neutralizer.
Looks good though. Nice job. How long did it take you?
6 hours exactly. I ran through my 65 gallon tank before even making it to the opposite side of the house, had to leave to go make another batch at home since I didn’t bring extra. I’m very pleased with how it came out but not pleased with how long it took us and how much chemical I ran through. But oh well. Learning experience
That’s really not bad. I would have allowed 4-5 hours in case there were areas I had to scrub. Deduct the time you had to go get more mix and you’re probably close. Looks really good though. Sometimes on a job you end up spending more time to get it extra nice. That will come back to reward you hopefully. Some great before and afters.
Why would you have to neutralize the roof after washing? Is that just for metal roofs or do you do that for all roofs
Spill or spray some bleach on a new Titan aluminum reel and then ask me, lol. Because the SH is very corrosive. Metal roofs secured by screws also and it will corrode around them unless you actually had a contractor use ss screws. You can probably rinse it really, really well and it would be ok, but can spray neutralizer on it after you rinse well, and then rinse the neutralizer off. Maybe take an extra 1/2 hour, but then you know you’ve done all you can. I charge a good price for roofs, so why not do the job as well as you can. On metal roofs it’s also a selling point.
Ok I gotcha thanks for advise … I will make sure to remember that if I ever wash a metal roof
What are you using as a nuetralizer?
I use Softwash Solutions Bleach wash, think they call it Final Rinse now. But most the distributors have something similar.
