How can I seal these two buildings together?

[maroon88iroc]

So I have a 30x40 red iron steel building that was installed on my property when I purchased the place, also had a 24x40 concrete pad infront of the shop. I purchased a 24x24 carport style building installed onto this existing slab. This building has worked out perfect for me I am very happy with it but unfortunately I was not there to supervise when the people installed the roof panels and there is a large gap between the new & old building.

I am attached 2 pictures of the gap I have. I am not into construction I am into restoring cars thats why I am here asking the experts what is the best solution for this situation.

thanks in advance for your help!

Isn't that the stuff they use to replace the bottom of a boat with a screen door LOL at that commercial

Yup,

The cheap fix would probably be to fill the gap with foam (either from a roll or the spray foam variety) and then use that as a backer that will hold sealant in place, then go on the roof and seal it up with some sort of roll/brush on roof sealant. Depending on how flat it is on the roof, you may be able to use some flashing as well.

Your pictures are hard to disseminate. I can't understand what I'm looking at.

This. More pics please.
I had a gap between My steel shop and a lean to. I spray foamed the gap, and then later used roof tar to weatherproof the foam. The tar ate the foam and it all fell thru the gap! What a mess! I had intended to cover the tar with a metal flashing.

What dues it look like from the roof? I think you will have to use flashing on the outside.

The correct way would to get some type of metal flashing from the original building manufacture that would match the shape of the sidewall.

I agree-proper flashing.And pics are hard to read.

x3 . . . MORE and BETTER Pictures.

Only proper fix is FLASHING so that water runs off taller building onto the shorter building. Flashing will need screwed to the building with silicon caulk so it can't leak behind the flashing.

Tell us HOW another building was installed by a vendor and this issue was not addressed then ?? Who built the 2nd building ??

You should use a flexible joint. They are commonly used in large commercial buildings to allow for expansion and contraction. If you search for expansion joints, you might find something.

I would use a flashing and some foam closure strips
That looks like r-panel siding They make a ouside strip that matches the panel profile.
Thet are foam so you need to coat the exposed top so they don't deteriorate

Click on "finishing touch flyer" it shows all the trim options.

Looks like a no. 5 to me. ( like was said above )

Your location would help.

you need a real sheet metal worker. with 24 gage min slip flashed under upper metal set in water block or mp1 caulking .most of the time I use a z closure with upper metal hooked over to allow for movement / call a roofing contractor that dose metal roofs

^^More information, and better pics would help. How long ago was the work done? If recently, My first thought would be to contact the installer, and politely explain the problem. Who knows,maybe they will come fix it for you.

Thanks everyone for the responses, I will get more pictures tonight, see attached for an overall shot of the new building against the old building. Not sure if you can tell but the new building in front sits completely under a gutter on the taller building so there is not much water getting into the shorter building bc all runoff water from the tall building is collected in the gutter but if we get a heavy rain it will come down the wall that is what I am trying to prevent.

The new building is a pre-ordered carport from an online retailer, I was never garunteed they could connect the two buildings together but if I would have been there I would have probably had then install those metal panels differently.

I like the idea of the Flashing that matches the taller buildings siding. This is an older style siding so I did not think I could get that flashing anymore. also the pitch of the new buildings roof would not allow me to just get a 90 degree flashing. Anyone know any online retailers that might offer something like this?

Also I am in the middle GA area.

you could also fabricate a false wall out of flashing against the old building walls. run it right up to the eves or soffet on the old building. if it runs up and meets the eves or soffets you will not need to be that precise with matching the contour of the old walls.

That is an idea to or you could move the building wall forward to cover the gap.

Where in middle GA? Detailed Metals in Griffin might be able to help. All my roofing and trim came from them. Blakes Builders in Griffin also deals in metal as does Balamo in Barnesville. There is also a place in Jackson but I can't remember their name.

This may not be the right way but ive done it twice with great success. Use a marker and trace the carport roof line onto the tall building. Take a angle grinder and cut a slit 1/2in above the marker line. Now you should be able to see day light inside the tall building. Now get some 3inx3in 90degree flashing. Slip the flashing into the slit you just made. Now use roofing screws to tack the flashing to the tall building. Last step screw the other leg of the flashing to the carport roof (you may want to lay down a bed of sealant on the carport roof under the flashing but I didnt and its leak free.)

This is the right way to do it. I would apply butyl tape before you install the flashing. If there are ribs on the add on building roof, you might want to use closure foam to keep bugs out.

Cyamaha 2007 is right on! You do exactly what he said & you will be VERY HAPPY.
But, cutting the metal is a loud noisey task. A piece of cake for a contractor.

Maybe some V-channel metal installed inside of the "new" building, all sealed up with silicone. Nice to look at on inside and then the V channel catches precipitation and guides it away (slope it)?

 

[jkrswld]

oops didnt see page 2 here. I agree with cyamaha that sounds like a solid idea.
