Yesterday I dyed the shingles. I had ordered two colors of dye- brown and grey. The effect I'm hoping to get is of a multi-colored roof. If you look really closely you will see three shades.
The first batch (about 3/4 of the bag of 1000 shingles) I did grey. I didn't want a really light brown, so for the second shade I added a little more water to the grey I was using and then dumped the brown dye into the grey. They came out a nice autumn brown. For the in-between shade (really hard to see in the photo), I then took a portion of the ones I had dyed grey and put them through the brown/grey stain a few times. This resulted in a darker brown shade.
I'm happy to see that they are drying nicely. Yesterday they just looked like a giant blob, but today I am able to see more of the actual color. I'm hoping to start attaching them this weekend.
