Hey guys I need a little info on a soft wash metal roof cleaning. I cleaned the customers other car wash location which has a tile roof and came out great, so he gave me his other location to clean but his roof is being very stubborn. I have soft washed tons of metal roofs in the past but have never come across this situation before.
The entire metal roof has this gold tint over the entire roof as you can see in the photo. Not sure if it is pollen, mold, or maybe even light rust stains.
On the far left you will see a small section I cleaned for a demo to show him that it can be cleaned. When I did the demo I came at it with a very light roof mix which has worked on every metal roof I have cleaned in the past. But it wasn't coming clean so I took a brush as well as rinsed with water and it came out pretty good. I figured it just needed a stronger mix and bid the job with a strong roof mix.
Well today I rolled up with some very strong mix and applied to the middle section which worked slightly after about 4 coats, but still not where I need it to be. On the far right i took a brush and went to town and it came out like the test spot did but when it dries it still has minor spots. I busted out the pressure washer to give it a tough rinse to see if the results were better and came out pretty nice.
I do not want to have to pressure wash this entire roof and informed the owner I would need to rent a lift to get every area to pressure clean the roof.
He is actually super cool and said if you cant finish it that's fine he knew the roof was in really rough shape and wasn't sure if it could even be cleaned.
But I do not want to leave the roof like this!!
Have any of you come across a metal roof like this before? What do you guys suggest I do?
Thanks,
