Dionised Water is cleaning the tiles.
« on: March 10, 2020, 08:47:46 pm »
Customer asked why there is discolouring on the roof tiles where the water runs off the windows and on to roof tiles.  I looked and agree that the water seems to be cleaning the tiles and leaving them a differnet color to the rest of the roof.  I then started looking at other customer windows which allows water to run down on to a roof.  Again all discloured due to the fact that they have been cleaned by the dionised water.  As anyone  else had this.  Its great that its keeping the tiles clean, but not in a way that the tiles are a completely different t colour to the rest of the roof.

Have you tried running tap water down them to see if there's a difference ? deionised water/purified water is no different to rain water so I suspect what you are seeing is tiles that look different when wet.

I've noticed this too. I've found that on the windows i run pure water on they're clean. And on the ones i don't they're dirty, so i do think there is something in this.

If it’s hitting lead and then going on to the tiles it’s the lead that’s cleaning them,look at directly below lead flashing or on a dormer window they all have a stretch of clean tiles from water that runs straight off the lead.
Something to do with a chemical reaction with lead and water I said to a roofer once if you ran a stretch of lead across the top of the ridge tiles on a roof they’d have clean tiles for years,he looked at me and said yeah they would lol.

copper is used in USA on the ridge tiles to disuade the growth of moss and algae. The water just washes off the residue of the oxidation process and it is that that cleans the tiles.
