Why 2" headlap on the bottom few rows? Looks like 11" -12" slates would have been better.
You didn't trim off the top of that slate on the 4th row, last picture. That solder looks like it's on the front edge of those laps. All that aside, some inspectors can be difficult. Maybe you could have used a closed valley for artistic value instead. |

Some of the concave roofs I worked on had gaps you could almost slide your hand in at the top of the keyway.

Two other questions. Why aren't you using copper nails??
And why do the nails you're using look like they're sitting high on the slate? Optical illusion? They don't look recessed in the photos. |

not a big blog-a.
They are copper nails (has noting to with the help I was looking for)! The solder is sweated in the seam. We don't trim the corners of the tops of the slate in the valleys around this area. All that aside: we changed it to closed valleys. Thanks for trying! |
