Rest assured. I started looking for a structural engineer several weeks before starting this thread.

Thanks for your insights. This is exactly the kind of information I was seeking.

Thank you for answering the questions I actually asked. [thumbsup2]

The problem is it is actually very difficult to answer the question ‘Is this roof structurally sound?’ because the structure of the roof is not visible. Even if as-built drawings of the original construction are available, it doesn’t guarantee that it was built that way or there hasn’t been any...

Thanks for pointing that out. From the photos it looks like the holes in the hanger flanges aren’t used at all. Rather, nails are shot right through the metal of the flange into the supporting joist. Also, one hanger has the top of the flange bent over the top of the supporting joist for some...

I’m told some inspection holes would need to be cut in the deck in a few locations to get a more complete understanding of the construction work on the sub-structure. I would have thought that a boroscope would be used which would be far cheaper and easier to repair, since it could be done with...

None. If it costs $100,000 to fix, we are not prepared. There is only one building in our development.

My understanding is that it would cost something like $100,000 if the roof deck needs to be removed and repairs made to the underlying structure. Although, this is something I need to clarify with our consultant.

Trust, but verify, as Regan said. I’m an engineer also, by the way. There has been some uneven settling and heave of the building foundation which was investigated about eight years ago. So perhaps that has something to do with the separation of the joists from the hangers. But the report says...

I checked both sides of the U-part of one hanger on a joist that is on the south side of the roof hatch opening (shown in one of the photos above). It does not have any nails on either side into the supported joist. So, unless there is a nail on the bottom of the U-part, it appears that the...

I'm only trying to gather as many opinions as I can. The ones I have so far have not been universally the same. In fact I have received one opinion from an engineer, based on the photos and the age of the building, that an inspection isn't even needed. One of the concerns I have is that an...

They wouldn't be insulation board nails because there is no insulation board above the plywood deck. The only thing above the deck is the membrane, which is a BUR (Built Up Roofing) system membrane. Thermal insulation is only the fibreglass batt between the joists as shown in the photos...

What are the issues that you see in the new photos?

I understand your point that an engineer should be hired to check it out. But do you see any significant problems based on what you can see in the photos? Here are a few more photos of a joist hanger and close-ups of the joists pulled away from their hangers:

I am on the board of directors for small condominium in Canada. The building was built in 1979, it is wood-frame construction and has a flat (i.e. low-slope) roof. Recently we had a roof consultant inspect the roof in preparation for replacement of the weatherproofing membrane, that covers the...

Thanks for the response. So, are you saying that an "intersection weld" is the weld used on a stub-in connection (ie: branch pipe to run pipe connection)?

Hello, I have a question for the forum: What is the meaning of the term "intersection weld" in section 1.3 of ASME B16.9, Factory-Made Wrought Buttwelding Fittings (the term is also used in 14.1.1 of MSS SP-75)? To be more specific, in the fabrication of a pipe-to-pipe tee (ie: a tee...
