Wow, hopefully that HVAC guy isn't responsible for any roofs caving in!

I'm glad our HVAC systems are typically in the basement!! 

So who sistered up that new green stud?

Just a slight mis calculation! lol

Your Friend in Charlottesville!

Good catch, Joseph!

Looks like the Boss came up and put a stop to the carpentry work.

Christopher, I hope not.

Tammy, I guess it's better to fall through the floor than to have the roof fall in on you  :-)

Bobby, I'm guessing the builder but I don't know for sure.

Charles, when I was up there it didn't even look like the notching was necessary to get the unit in.  Just a lazy guy I suppose.

Steve, thanks for stopping by.

Keith & Robin, that's what I think.

You are definitely right Joseph, buyers should always make sure that their inspector will go in the attic and of course in the crawl space as well, when they are accessible.

Also you've touched on a great point here regarding foreclosed properties. The bank never lived there and so has nothing to disclose to the buyers which just makes the need for a good home inspection that much greater.

Joseph, it is all part of the "get a bigger hammer" approach to building.

Looks like a notch job to me.  What a shame people can't own up to the problems they cause others.

John, thanks for the comment.

Charles, I like that term.

Gene, they should take DNA evidence and track down the worker  :-)

Plumbers are also notorious for notching beams, joists, and the like.  It amazes me what people will do to  a structure instead of finding the proper means to install something.

Yikes!!!  Obviously one never wants to see a truss compromised, but how much would be acceptable?  That only seems like a little amount, and much more would be bad, but is a little bit acceptable?

Jennifer, I agree.

Derek, I actually took the class "Statics" in college.  That's where you evaluate static (non-moving) loads.  A truss distributes the weight of the load throughout the truss system, therefore every component is going to carry some load.  That's why only an engineer can okay a modification to a truss (no matter how small).  I wouldn't take a chance with something like that.

Wow Joseph.  It is amazing what some people do.

Richard, very true.

Joseph - very interesting!  I guess based on that theory, even a hairline change can be HUGE.  Good to know ... thanks.

Derek, it really depends. Remember, wood isn't perfect and may have slight cracks from drying out, etc.  However, notching is a totally different issue.
