Stone Roof Repair - (real stone, not that cheap slate stuff)

I recently had a chance to work on one of the old estates in northwestern PA. Birthplace of the modern oil industry. Drove about two hours for a measly 2 shingle roof repair. Lots of fun working on a one of a kind roof. ( One of a kind in the US. There's many of these stone roofs in the old country.)

Jed,

Are you saying that the covering stone worked itself under the lip of the nail and curled it up into that mushroom shape?

Copper nail head.

Looks like maybe the copper was wrapped around a lead cap?

I tried to reply yesterday, but I crashed! Dang it. That's what a real roof looks like, alright. I've thought about shanking my own stone like that, but I need more knowledge than I have, and access to the right stone to boot. Nice job.

What/how much corrosion are you talking about? The whole head rotted off like an EG nail after 7 years? Just 'ruts' in the copper, like lead does? Or just vergis?(sp)

Thanks all.

Rafters are 2x6 rough sawn. Steep pitch and short joist span limits sagging? Previous owner opened up the attic/ceiling and made cathedral ceiling exacerbating the ice accumulation on the front dormer. It used to have gutters.

If I put apprentice lauzier on my resume, can I charge more?

5 1/2" SS #12 on top piece,and 4 1/2 " on lower shingle. Drilled and countersunk. Top piece I lifted the crappy apron and installed screws. Originally the nails were covered with mortar. I sealed with silicone so they could be easily removed when proper repair work was done. Lower piece is screwed through the joint and covered with a copper bib.

Odd thing about the original copper nails. They were corroded at the shank/head. Just the top. The "head" of the nail seemed to be a washer. Possibly a lead head or washer that corroded? I dunno.

He used SS screws.

Hate to be standing there when one fell loose.....frick..

If you keep packing stones like that up a ladder by yourself you're going to live up to that surname. j/k Thanks for sharing that one with us. Still wondering about attachment. Where did you put the screws?

I like the way you handled the statement in the 'about us' section of the website. Actually, everything on it.

I think I would travel the 2 hrs to work on it too, I have a feeling a two shingle repair on that could eat up most of a day though lol. What kind of rafters do they have? All that weight and I didn't notice any sagging so it must be well framed.

My back started hurting just thinking about lugging those up the ladder, especially some of those 3 footers :blink:
