Hay gang, how is everbody, been a while since I been here, Mafia Wars is gonna cost me a crop yet...lol I got a job comin up in a few weeks, here are sum before pics. this is a job that we did about 15 yrs ago. The owner shipped in some type of man-made slates from California, that were supposed to be warranted for like, 50 yrs. Well it aint been but 15 and they are starting to fall apart rather badly. It doesn't help that we have had a couple of hail storms on them too. Have any of you guys ever seen this type of slate? The company that made them either went out of business or was forced out from prob. lawsuits over the warranty from failure to hold up. http://jalbum.net/a/954830/
The problem with any hard roofing material is that if they are not steep enough, people will walk on them. They will break and crack, because that is what they do. Not a walking surface. With that said, they are long lasting and beautiful when properly applied. I have done many myself.
OS, looks are one thing. Performance is another. Slate will do both superbly. There is nothing that can touch it for looks and longevity both.
I have a long article or a short book written about just this thing. I have been working on it for two years now. One of these days I might even put it online.
Everyone wants to install something that looks just like slate. Guess what, nothing looks quite as much like slate as ......SLATE. go figure.
Actually, I am serious. I have re-read it many times and it is quite good.
Going for the 50 year roof that looks like the devil in 20 years and needs to be replaced in 25, eh? :laugh: :laugh:
None of those wannbe slates have any comparison factor to real slate. No sense in putting a roof on that can last 100+ years. :P
I think this feller has had his bait of slates or slate wannabe's. We are going to put back a composition roof. We are looking at Certainteed's Carriage House or Centennial Slates.
I didn't see all the pix. 3" headlap on the 6/12, and 4" on the 4/12 will work. It'd be better to use copper SS for the lower pitched sections. But, I don't see any issues caused by the low pitched sections where the temporary roof was installed before.
---I am not a slate person... ---I question whether slate is the best product for a roof with large sections of 4/12 roof pitch. I can see where the product is at fault by its decomposing. But why put slate on such a low sloped roof? Seems like asking for trouble. Lanny
Don't forget, the roof has to be scaffolded. You can't step on the finished areas and walk on the slate. And the new OSHA rules will really slow you down too. 1-2 square a day is the norm for production.
Every slate has to be culled and even fitted into place due to variations in size. Slapping them on without nesting for best fit will lead to early failures. Here's an example of how to create a leak and build it into the roof job.
Another.

roof_dawg Said: Is $2000 installed price w/ material? Just curious, there are very few slate roofs in this area.
Of course. Nails alone are about $600. a box.

Well, they lasted longer than normal. :dry: Now, put some Buckinghams on there for $2,000. a square, with stepped caps, copper nails etc, and we'll all be dead and gone before he ever has trouble again.
Suprador slates. I believe they took over for Johns-Manville when J-M had all of its' asbestos troubles. Those are the J-M asbestos slates minus the asbestos. It didn't work too well!
....oh yeah, I forgot to tell ya, he paid $250 a sq for these. 110 sq on this plus cappin.
