Good question! Slate is very forgiving would be the best answer I can give. I talked to another roofer in town yesterday about a different roof. He has gotten a job to re-slate a roof but didn't know that the slate he was going to buy was the true slate instead of real slate. He also didn't realize that the existing roof was a graduated slate roof. I tell ya, the tuition on these is going to be a bitch! | ||

With that said: how do you explain tiny bell tower slates functioning on a 6-12 pitch with only 1 inch of sidelap: (3" wide slates). I've repaired two of these and scratched my head both times because it defies logic, but the roofs where both there and dry for over 100 years no underlay either. I don't think it's good practice but I've seen it done and last a long time | ||

Problem with gapping slates like that is the nails aren't covered adequately, increasing the likelihood of leakage. The object is to center the joint but also to cover the nail as much as possible. | ||

I looked at those pictures of the spread slate again and I figured out when the other "roofer" was thinking. Whatever slate he had in his hand was installed and it went over the slate below it almost centered on the joint. That gave him the best chance of not having the water run beneath them, but also explains the widely varying and random gaps between the slates. What a goof! | ||

I have worked on this castle over the years, but not for the last 20. I have to put together the spec for the rehab of the exterior`and hopefully they can get the money together to save it before it falls apart. I have never seen any slate repaired quite like this one. I guess "Wow" says it all. https://picasaweb.google.com/crookston.john4/HendersonCastle?authkey=Gv1sRgCOq28 sCpxdHSaQ#6141085858916171202 |
