Installed one just like it except I used butyl tape for the seal rather than silicone. Nice product, seems to be holding up perfectly after 1 season at least.
I need to put a chimney through a sheet steel cabin roof, I've been trying to figure out how to do it properly with that steel flange you removed. Seems the more research I do, the more I think it's better to go with one of these flexible boots. They aren't cheap, but in the end, knowing they will seal properly is probably worth it.
It is such a tight fit around the pipe that it is watertight. I still ran a bead of RTV silicone around it, but you cut it to size and it fits really tight
What do you do if the gap between the ridges is narrow enough so that the Dektite boot blocks the flow of rainwater to the gutter on a nearly flat roof?
I typically do that as well, but we were trying to cover up the previous installation, screw holes and this is such a shallow pitch roof that it doesn’t really matter anyway
I think you would be fine screwing it to the roof sheeting/decking. I wasn't screwing this into the purlins, just the metal roofing. Works phenomenally.
@@BryanHansen Really? I'm worried it will act as a water dam and leak. I might orient it at as a diamond to help shed water. i don't have as good an orientation to the ribs as you do. I would use a standard metal flashing if I could but the chimney I'm using its a weird size and not standard in the U.S.
I'm an old single dummy gal, im doing this myself, would you tell me what brand of silicone glue, or is it just silicone? I'm in Montana too so cold temps, I hope you answer questions I'm hoping to fix my pipe this next month, still have to order that rain boot, thankyou!!!
@@BryanHansen we have the pelated kind here. It was caught before it was broken through but it definitely was nearly compromised. I loosely reinstalled the old cowl over it just to be sure.
Great job ,I used 1 of these boots, and yes ,seal all the way around. When using the steel boot on an asphalt roof never seal the bottom .that's where the water will escape.
Nice, I'm hoping to attempt this. So do you put any roofing silicone on the join between the flue and the top of the flashing? Or is that a secure seal?
@@BryanHansen Yeah it's coming in between the roof and the dektite mate. I put a lot of silicone (and screws) so it's a bit frustrating. Unfortunately the flue is pulling the tin roofing down slightly causing a depression which is allowing water to pool around the seal.
If I'm not wrong, I don't think you're supposed to use silicone to seal it. I think you're supposed to use a polyurethane based caulk but you might want to check..
@@BryanHansen Ok I have been just scouring to find if double walls are cool enough for them. I actually just want to install it at the top of my chimney chase because of the type of cap I have would benefit from a boot type install.
@@LukeAudette guaranteed it would be cool enough. My stove running coal through single wall up at the cathedral box isn't 200 degrees fahrenheit (more like 125) where it goes out the chimney top. They are rated to 392 degrees fahrenheit. You will be plenty good.
Thank you! This was incredibly helpful. Mine didn't come with instructions, so your specificity of tips is greatly appreciated.
Thank you Mr. Hansen for this video!
You bet!
Great tutorial, thank you 👍👍
Awesome video.

We use Haslet Roof Top platforms. A lot less cutting, it seals great, and actually looks good.

This was such a better solution when it was all said and done. For a metal roof this is the only way to go IMO.
Warning, if you have a galvanized roof make sure your silicone is not acid cure. It will corrode.
has you’re boot had any problems with melting or not withstanding the temp of the chimney pipe?
No, not at all and I’m burning coal. The red boot is the high temp boot and it has performed perfectly.
How do you seal the top of the dektite onto the chimney?
It is such a tight fit around the pipe that it is watertight. I still ran a bead of RTV silicone around it, but you cut it to size and it fits really tight
Good video thank you. Those flashing are for high temperature. But are they resistant to sparks coming up the chimney and touching them?
Very. They work great. No complaints after running them for 2 years now.
@@BryanHansen thank you
What do you do if the gap between the ridges is narrow enough so that the Dektite boot blocks the flow of rainwater to the gutter on a nearly flat roof?
Install it in a diamond configuration to help it not block the flow of water.
Can you install thin on the peak? My chimney come out right on the peak and cant find a flashing that works
Definitely can
I turn them like a diamond. Less surface area for water and gives it a path to flow away
I typically do that as well, but we were trying to cover up the previous installation, screw holes and this is such a shallow pitch roof that it doesn’t really matter anyway
Good job
Hi Bryan, is a storm collar required with a silicone boot? Or is it more like- "could be helpful, why not!" thanks!
Definitely a “could be helpful, why not”. I had it off of the old one and decided to reuse it on this one.
We always silicone the storm collars also. Good job
Hey, do you think most rubber boots can be screwed just directly to 3/4" roof decking? Or does it need 2x4 or 2x6 framing
I think you would be fine screwing it to the roof sheeting/decking. I wasn't screwing this into the purlins, just the metal roofing. Works phenomenally.

@@jackktorness it should all seal up. That’s why you use the silicone and gasket washer screws.
@@jackktorness Unfortunately when you go diamond pattern it overlaps more tall ribs. This in my opinion makes more areas of damming.
Is the flashing still good I saw a picture of one catch on fire that why I’m asking
The only way that would catch fire is if the entire building caught with it. It is silicone and rated at over 500°.

This is the exact glue I used and we live in similar climates. amzn.to/3yFWSQ4 here is the boot too: amzn.to/3aOzBDR
@@BryanHansen I really appreciate it, I had found the boot but I was especially concerned about the sealant. Thanks
Does the steel roof require 2 inch clearance?
No because it's not a combustible
does anyone have a link to the correct rubber boot shown here?
Here: amzn.to/3DSIc2Q
Awsome ! Which size did you order ?
The 7-13”. amzn.to/424VcgX
You know what likes these damn things? Woodpeckers. Just a tip don’t throw away your old steel cowl. It may come in handy.
Odd. We are lousy with woodpeckers and I haven't had one touch ours.
@@BryanHansen we have the pelated kind here. It was caught before it was broken through but it definitely was nearly compromised. I loosely reinstalled the old cowl over it just to be sure.
You don’t apply silicon to the bottom edge, only 2 sides and top so if the silicon fails it allows the water to escape.
Not per the manufacturer.
Great job ,I used 1 of these boots, and yes ,seal all the way around. When using the steel boot on an asphalt roof never seal the bottom .that's where the water will escape.
Nice, I'm hoping to attempt this. So do you put any roofing silicone on the join between the flue and the top of the flashing? Or is that a secure seal?
I have put a bead around it before. It is a tight fit, but it doesn’t hurt anything to put RTV around it.
@@BryanHansen
Yes, for sure. I think I'll do that, cheers 👍
@@BryanHansen
Argh, I got a leak 😒
@@carl8568 coming down the pipe or around the roof seal?
@@BryanHansen
Yeah it's coming in between the roof and the dektite mate. I put a lot of silicone (and screws) so it's a bit frustrating. Unfortunately the flue is pulling the tin roofing down slightly causing a depression which is allowing water to pool around the seal.
If I can't necessarily get the top pirce of the chimney off. Could I just cut this boot somewhere to wrap it around and tar the seam?
You could, but I would cut the pipe before a spliced the boot
They now make a split boot that you can use if you can't get your top piece off: amzn.to/3RDdI9R
What temperature is the boot good for
392 degrees Fahrenheit
If I'm not wrong, I don't think you're supposed to use silicone to seal it. I think you're supposed to use a polyurethane based caulk but you might want to check..
Nope! Right from the manufacturer instructions: "Apply neutral cure silicone
sealant on underside of flange"
He did it the correct way it's a high temp SILICONE boot SILICONE is what is recommended under the flange
Does the steel roof require a 2 inch clearance?
For which piece? Want to make sure I am answering your question correctly
@@BryanHansen 2 inches clearance between the steel roof and the chimney pipe
@@badromenful no. Not at all. Only from flammable items. I peeled back the insulation underneath back from the triple wall pipe 2 inches.
Where did u buy storm collar
You can get them at home depot or any improvement store, but this is the one that works for 6-8" triple wall pipe: amzn.to/4aRD8eL
Double wall or Triple wall chimney pipe?
Single wall to the cathedral box and then triple wall out the cathedral to the cap. But, use whatever your ceiling box requires, double or triple.
@@BryanHansen Ok I have been just scouring to find if double walls are cool enough for them. I actually just want to install it at the top of my chimney chase because of the type of cap I have would benefit from a boot type install.

Are these only for steel roofs ?
What type of roof are you wanting to put it on?
I think he has a glass roof😂😅
You should’ve put it like a diamond shape the other the water don’t have a damn it goes around it
If you watch the video, I explain why I didn’t
