Designing a breezeway from the garage to the house. My question is in regards to the connection plate that connects the roof to the side wall of the home. The home walls are ICF and I want something that will allow for movement of the roof and connect to an ICF/concrete wall.

Since I am using 4" SIPs on the garage, would it be easier to just continue with a SIP roof for the breezeway? I know the insulation would be wasted but it might be easier to just continue with the SIP roof for the breezeway.

Will the roof line of the garage continue across at the same elev. to the house? My breezeway was about 1' higher than the garage, I made beam pockets in the ICF before pouring, for the pine 6x10s to sit in. On the garage side I beefed up the corners where the beams would rest in.

The garage roof line is NOT on the same elevation as the house roof (it's a 2 story home).

Do you have any close-up pics of how the beams anchored into the ICF wall? How do you waterproof that area?

I would go SIP for the roof for several reasons. One, if I build anything, i like to get as much use out of it as possible, so I would make the breezeway somewhat of a porch. When it's hot out, the insulation of the roof would make the breezeway more comfortable for sitting out. I'm surprised how much heat radiates through my porch roof. Secondly, over the years, structures tend to get used for other purposes. I could see enclosing a breezeway to make a greenhouse of sorts, and of course the insulated roof would benefit that as well. I've seen a lot of porches, garages, and yes, even breezeways converted to living space down the road.

As for attaching the roof (or any structure) I would make voids in the foam so that the concrete comes to the surface, and embed J-bolts in the concrete while pouring. You can then attach anything you want to the ICF wall.

When I attached my front porch header beam (3.5" wide x 14" tall) to the front of my ICF wall, I removed the outer layer of ICF foam the same size as the end of the header beam plus an extra 4" below the header beam for a piece of steel angle. I used blue tapcons and construction adhesive to install a 3.5" wide x 14" long treated 2x4 to the concrete. I then used two (2) 1/2" Red Head anchor bolts to attach a 3.5" wide piece of 4"x3"x1/4" angle steel below the 2x4. This provided a steel shelf to support the end of the header beam. I had a couple of small holes drilled in the steel angle to allow running a couple of deck screws through the steel into the bottom of the header beam. I also used 4" long deck screws at 45 deg angles through the end of the header beam into the treated 2x4 attached to the concrete. After the install was completed I came back with some canned foam and sprayed over the piece of angle steel and then trimmed it flush with the ICF foam when cured.

I did almost the same thing as arkie, except I used a strongtie joist hanger with the turned in attachment and the tapcons. I cut the foam to the dimensions of the beam down to concrete. I then flashed the beam to the wall using foamboard adhesive. It was an idea I passed by my PE first, and my inspector loved it.

Simpson makes a beam hanger, as seen here:

GluLam Beam Hanger

They recommend TITEN screws to install the hanger into the concrete wall.

Lbear, All I did was use a piece of ICF, placed it inside the ICF block where I wanted the void created in the concrete. The beam is sitting on 3 1/2" of concrete (inspector fine with that) couple of screws from top plate into beam. No water proofing, this area is 2' under the breezeway roof.

I wanted to use that Simpson HUC410 beam hanger, but couldn't find any locally. I only needed one (1) and was kinda pressed for time is why I made my own solution.

Note also that those Titan screws appear to be just Simpson's brand of blue Tapcons that you can get at just about any lumber/hardware store.

I ended up using the hanger (it was an HUC) because I missed putting in a pocket. I also couldn't get the hanger locally, but it was only a day wait, my supplier gets a truck up from the big city everyday. As far as screws I used the Tapcons because the local orange box carried the right length, they didn't have as good a selection in the Titan, and if you check the specs you will find that you are splitting hairs.
