Weird framing for a Truss system, thoughts?
 
I attached the photos of the truss system I inspected this morning. No ridge board? The Trusses are also 24 inches on center for the most part. There is an area where they are less than 16 inches on center.

Not sure what to recommend here. Anyone have any recommendations?

Weird framing for a Truss system,...?
I don't believe I have ever seen a truss system with a ridge board and 24" on center is normal...16" o.c. is stronger, no?

The center struts do look a little out of alignment, though, and I can't tell if there is any diagonal bracing needed from the pictures.

Were the center struts loose anywhere, especially on the bottom?

24" OC is fine, as with anything less. Typically truss members over 5' have some type of bracing, stiff/strong back and/or horizontal bracing across the trusses is common practice. Blueprints should be reviewed to make a definitive recommendation.

That's coming back to me now, Dave...10' max spacing on lateral bracing (or, less distance on long spans for temporary),and as prints show for permanent.

What you have is a typical truss system. No visible issues. Trusses do Not have a ridge board. 24 inch on center is common.

You should consider brushing up on the Basic fundamentals of residential construction.

Truss systems don't have ridge boards, and they are 99% of the time 24" OC. Is this the new norm now? Are we not getting the proper training anymore?

It would help immensely.

It appears so...CMI, too? :shock:

I am thinking of concrete tile roof systems I see here almost daily to
lighter materials would have different requirements .

Mr. Murphy, I am sorry but if you have been doing 20 years of Inspections and a CMI as you claim on your Website, and don't recognize a standard roof truss system, you are definitely doing the public an injustice and falsifying your credentials to make an unethical charge for your services.

I would highly recommend another line of work to fit your capabilities.

First, I am not a CMI, nor have I ever said I am. I would recommend you read the entire page (instead of the header) before you assume, and go out of your way to insult them.

In this photo you can see a ridge beam.
Ridge board must not be the right terminology for this system. I know it's not required but the truss webbing is at an angle I have never seen before. Not to mention an improperly supported package unit on the roof. I was asking for thoughts not insults. Thanks for the advice...

That's not a ridge board. It's part of gable end bracing, and not adequate for high wind loading. There is plenty of information out there on truss systems to research.

The center struts were twisted. And they look out of allignment to me. Ive seen 24 and 16 OC obviously. I just don't normally see both used in one house.

Yes, we don't see much of that up here. :)
