The roof doesn't look out of the ordinary.

2 questions on this slate:
1. A year after installation I am seeing some brown (rust?) streaks mixed in with the natural striations in this slate, seems to be on most slates, some much more than others. I understand this slate will weather some (Approximately 4% to
6% of these slates will exhibit slight signs of
weathering after 12 to 18 months of exposure) Is this something to be concerned about? Are there some bad "deposits" in this particular batch? If this is the weathering that is referred to above it is happening on more than the 4 to 6% mentioned.
2. The slate has a very rough texture, not just on the edges, but on the flat areas. I am noticing some chips of slate in the gutters and on the lawn. Is the roof breaking down? Is this something that will stop and stabilize over time. I've seem many older roofs with much rougher textures are they seem to be fine.

The slate was from Greenstone, from the Briar Hill quarries, as per their website.

Some photos are attached.

Thanks in advance!

Joe
