Hi. Rafael:

Hope you are fine.

Looking at the pictures, it is hard to figure out.

A smart-butt answer would be, they ran out of 2x6. ha. ha..

From the pictures, I can see 1x6 boards at approximately 12" O.C., with wafer board on top, most likely 7/16". Why would they do that in lieu of one layer of advantech, plywood, or boards? Maybe I am not looking at the picture right.
The ridge should have had a 2x6 continuous and not knowing the span of the rafters, can not comment on wether or not the collar ties are adequate that close to the ridge.

What is that pipe in the picture that seems to be held by a pipe strap?

Marcel,


You are looking at a home that was originally roofed with cedar shakes.Hence the 1 X 6 or more likely 1 X 4 solid slats.


When the shakes were torn off 7/16(probable thickness) OSB was placed over the solid slats to form a continuous sheathing surface to accommodate,most likely, asphalt comp. shingles.


The practice is very common.


I hope this is helpful to you in the future.


Regards,
Cheremie

Hi. Rafael,
It appears you will get help one way or the other, thanks to this board.
There is nothing more valuable that communication.

Cheremie;
Thanks for the input, I now visualize the full picture, due I am aware of the installation of the cedar shingles the old fashion way, but in this part of the Country, I haven't seen in 40 years. I guess, when I was looking at the picture, I did not realize the roof had been renovated. My mistake, ha. ha..
Rafael,
Now that I know that is a transite chimney, do you realize that this contains asbestos. Should be checked.

Thank you all for the information.
Take care.
Marcel

Marcel,


Tell me more about transite.I've probably seen it and didn't know what I was looking at.Even worse, in my younger years, I've probably even torn something like it out under the close supervision of my first and only boss.His favorite supervisory chair was in a bar.He would dump me on a job site and leave me to figure this stuff out at the tender age of 16. His teaching method was, however ,succesful. I quit him and went into business for myself.

Take care
Cheremie

Hi. Cheremie;


Tried to find information on the transite asbestos product for you, but obviously,lawyers firms keep popping up, guess it is because of this money making mesothelioma deal for people that worked with this product over a life time.

To answer your question, I worked with transite board material in 1972, installing it on the facade of a Zayre Store I was building in Madawaska, Maine. At that time I had no idea what that product was made of. We cut it and made dust all over the place. We did not have carbide blades for our saws and had to use abrasive blades. Dust masks, none in site, and did not know about them. The transite board was used as a backerboard for an epoxy applied stone rock face. The adhesive was troweled on and the 3/4" stone was actually placed by hand by being pushed on the product and would stick to the adhesive.

At the same time, the water and sewer district was also installing piping of the same material. All pipes were cut using abrasive blades with no air inhalant protection.
The product was of a gray color, resembled cement piping or the such, was heavy, and very difficult to cut at the time. Of course, Maine has been ten years behind technology for a century or more , ha. ha. .

Carbide blades would have produced the same hazardous dust, if we would have had them.

Chimney material was also manufactured at the time to resemble the pipe in this forum.

Anything that you see in the future that resembles this character of composite is asbestos containing product. It is not a friable material and is safe to look at, but do not cut it in any way. I am surprised to see myself talking about it when I installed it, cut it, breath it, installed asbestos joint compounds, sanded it breathed it, and still here to talk about it.

Hope this helps you understand this product, and hopefully some other forum reader might elaborate on the subject.
Hope this helps and any communication amongst us always helps to enlighten the reality of the consequences of technology.

Have a good night.

Marcel
