A slate roof I am working on

Old School Said: Thanks clover. I was having a hard time wrapping my head around that one too.

Yeah Max. We used HT with titanium over it on the big tile job I did a few years ago. Anything with asphalt on it will stick to the slates or tiles and make it a bitch to try and repair them in the future. As long as the surface is a slip sheet, it will work just fine.

You want all of the penetrations through the roof before you start to install slate or tile. The carpenters and plumbers havent a clue how to do it and they make a BIG mess. better to dry it in and wait. Having a material that will hold up for 6 months is amazing. Good stuff.

There must be 20 different vents in this roof and they will all be copper, just tryin to get in the dry for now. I remembered that tile job when I saw that pic. That is a great way of doing it. With the woven top, the slate sealing to the underlay will not be a problem here.

Ah, now it makes sense. If your winter was anything like the one we just had here, you will be glad you dried it in like that.

Slate not. This is going to be a interlocking flat tile roof. One I"ve never seen before. 15 3/5" X 9 3/8" or 40X24cm exposure. Good thing it is a low pitch.

Nice project.

Worked there all day today with the guys and too=k some more pictures. It is coming right along.

You know, after looking at the scope of work being done, I'm surprised he didn't spring for enough snow guards for proper retention at 4'-6' vertical intervals.

Nice looking work though. :)

Tinner, We looked at that, but most of the area around the building is going to be open, and rather than fight the snow and ice we decided to let it slide off the roof onto the ground. I will hold the front lip of the gutter down so that the snow can slide right over the top of it.

That's also a good idea and the correct way to hang gutters. :) I guess I was more concerned with the buildup of snow and ice that occurs at the eaves. BTW, I watched some of the roofs I covered in SG's and the snow seems to melt off the bottom nearly as fast as the ridge. I start about 2' up from the gutter.

I was just curious and don't have much experience with the snow amounts you get. :)

This is going to we insulated and well ventilated, so most of the snow should remain so. I just want something over the doors to protect them. The farther east you get from Lake Michigan, the less snow you get, but it can get nasty. they had a lot there this winter.

I worked there again today. Here are the pictures we have. It is coming along well considering the amount of rain we have had to deal with. It should start to move faster as the guys are getting it and the hard cutting is about done.

John,

That's really gorgeous work, from what I can tell.

Can you give me some close-ups, or even better, a detailed description of what I see where the dormer ridge meets the main slope. This flat-lander is having trouble comprehending what I see with the copper flashings in this photo https://picasaweb.google.com/crookston.john4/ChelseaSlateRoofing?authkey=Gv1sRgCI2___6w6pnzqwE#6016418306503613266

Mike, we bent up a "trough" valley in copper and brought both of them together at the peak. The tops run through and overlap at the peak. The pictures are actually in reverse order, as we took a piece of beveled 2 x 4 that completed the peak and it slid underneath the copper to support it on the peak of the dormer. The tops of the next row of slates attached to this nailer, and then we put another nailer at the peak to hold the ridges on with. This whole assembly was covered with another piece of copper flashing and that flashing covered the joints you are seeing in the picture you highlighted. It was then covered with the ridges that installed last. I will see if I can get some better detail pictures the next time I go over.

Dear Old School:

I featured this in my eblast this week. Sorry I didn't ask you first. I just had too. I love watching you work and everyone can learn something from you. Don't be mad. I'll be more proactive next time.

Vickie, I don't mind as long as you give credit ...or blame, as the case might be. I really enjoy that type of work and it is my mission to teach as many people about slate and tile roofing as I can before I have to give it up. I will be 62 in a bit over a month and I have been working on roofs literally all my life now. I have home movies of me on a roof when I was 4, so that makes about 57 years.

If I can take pictures of things and give as many details as I can, I know that the capable roofers will get it, or at least have the information so that they can ask the correct questions. For guys like Tinner or copperman that work with this stuff all the time, it an opportunity to put myself out there and get their critique or criticism to, and that makes us all better roofers. I certainly don't claim to know it all, as I learn something new every day. Glad I can contribute in any small way.

BTW. What is an Eblast, and where would I be able to read it? Old School.
