Looking for someone with knowledge of roof construction.

We're installing an HVAC system and all of the bids we received said they would put it in our attic. We chose a mid-range bid from someone with 20 years' experience, licensed, and bonded. Now that job has begun, he says our attic is strange as we have these angled 2X6 beams somewhat haphazardly placed throughout the attic space.

He sent pics to a friend of his who is a builder, but they are both unsure if these beams were used to shore up the roof during construction and would normally have been removed, but for some reason they weren't, OR if they are actually load-bearing support beams.

Unless they are cut, there will not be the 9ft of space the heater, compressor, etc. requires. The HVAC guy's suggestion is to cut them, place the units in, and then replace them with 2X4s just in case.

We've asked neighbors who have similar home construction and no one else seems to have ever had an issue with this when they installed their HVAC systems.

So, we are left wondering if these diagonal beams really are useless beams or for some reason our if our roof needed extra reinforcement and removing them will cause a cave in?

As usual, we're getting different stories depending on who we ask :plain: and could really use some HELP.

I've added pics of the angled 2X6s in question (they're the ones that are diagonal and look sort of "off" not the ones that are horizontal/vertical). If there's anyone out there with knowledge of roof construction--or knows someone who might-- who might know why these are there or if we should be concerned, would you please let me know?

We're first time home owners and have already learned it's hard to know who to trust. Sorry for the long thread and thanks for reading all that!

THANK YOU!

Have an engineer come out and determine if they need to be there. While this will cost you some money. it also gives you some safety, if he says they aren't structural, and he turns out to be wrong. It falls back on his insurance.

If someone here says they are not structural, and is wrong. Its on your dime for any and all repairs later.

Codes require a ridge board bigger than the rafters, which you have. The diagonal boards were for the install, they can be removed, The cross boards (above the ended ceiling joists) are the required "elevated" rafter ties- do not remove- they really should be 2x4's, 2nd para.; http://publicecodes.cyberregs.com/icod/irc/2009/icod_irc_2009_8_par022.htm

The 1x boards (1/2 attic span serving as stabilizer) over to the temporary ridge braces (diagonals) can also be removed.
