Installing a Dektite silicone boot flashing on a wood burning stove chimney

[@BryanHansen]

A follow up to this, I added a Kuma Snow Cricket in front of the chimney. You can also see how well the boot has held up 2 years later: kzbin.info/www/bejne/aWKrgX2Hjb9qn7Msi=AOoQDJrFwy_zuIkA

[@jimconrads9515]

Thank you! This was incredibly helpful. Mine didn't come with instructions, so your specificity of tips is greatly appreciated.

[@erice9536]

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.

[@markmeyer9571]

Thank you Mr. Hansen for this video!

[@BryanHansen]

You bet!

[@toolsteel8482]

Thank you for sharing this. I want to put triple wall smoke pipe through my garage- shop roof & this seems like a simple way to accomplish that. I would prefer it to be grey or silver if possible though.

[@BryanHansen]

The Orange are the high temp ones. They have black, but that is intended for plumbing not heat. If you are using Class A or Triple wall pipe...honestly it should be cold enough that you could use one of the black dektite boots. It is rated to 239 degrees fahrenheit. Honestly if your pipe is hotter than that, you likely have other concerns to address. I burn coal in this stove and that was a concern, but to be honest it is never over 150 at this point in the chimney. So you could use this one: amzn.to/4f1Z20E

[@MrSprintcat]

Awesome video.

[@Redlinesixtynine]

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.

[@BryanHansen]

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.

[@sueby1409]

Great tutorial, thank you 👍👍

[@EasyAim1]

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

[@KevinMaxwell-o3t]

If I may add a comment, I believe butyl roofing sealant would be a better choice. Silicone sealant is highly over-rated and prone to failure.

[@BryanHansen]

I don't disagree with you to be honest. Butyl is great and if installed correctly makes a good seal too.

[@mikestamm101]

Is there a reason why these are bright orange in color?

[@BryanHansen]

@@mikestamm101 to easily identify the high heat boots.

[@Massey-yj2dx]

Hello how long do these boots last does the sun rot them away in a few years

[@BryanHansen]

@@Massey-yj2dx the sun does not rot them away. I’ve had one on another installation for 8 years and it’s as pliable as the day I put it on. They last great!

[@warwickcathro2650]

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?

[@BryanHansen]

Install it in a diamond configuration to help it not block the flow of water.

[@silverhustlin1390]

How’s the boot holding up 2 years out? Thank you Sir

[@BryanHansen]

@@silverhustlin1390 fantastic. I actually posted another video last week of it. I installed a snow divider in front of it.

[@adanmendozamonterrey]

Is the flashing still good I saw a picture of one catch on fire that why I’m asking

[@BryanHansen]

The only way that would catch fire is if the entire building caught with it. It is silicone and rated at over 500°.

[@blakehafling6995]

Warning, if you have a galvanized roof make sure your silicone is not acid cure. It will corrode.

[@cocinaycocteleriaconjunjun7823]

Good video thank you. Those flashing are for high temperature. But are they resistant to sparks coming up the chimney and touching them?

[@BryanHansen]

Very. They work great. No complaints after running them for 2 years now.

[@cocinaycocteleriaconjunjun7823]

@@BryanHansen thank you

[@itsoktoberight4431]

How do you seal the top of the dektite onto the chimney?

[@BryanHansen]

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

[@dillonwilliams7384]

has you’re boot had any problems with melting or not withstanding the temp of the chimney pipe?

[@BryanHansen]

No, not at all and I’m burning coal. The red boot is the high temp boot and it has performed perfectly.

[@scottdieboldsr.3594]

What screws did you use? Are you just screwing the boot to metal roofing or all way to plywood underneath? Thanks

[@BryanHansen]

@@scottdieboldsr.3594 I used sheet metal screws that have a rubber gasket. They were actually extra ones from the building. Essentially these though, amzn.to/3XPKJoe and just into the metal roof, not wood underneath. Held great.

[@scottdieboldsr.3594]

@@BryanHansen thank you

[@TheDond56]

I turn them like a diamond. Less surface area for water and gives it a path to flow away

[@BryanHansen]

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

[@MrSprintcat]

Good job

[@flowerpower9541]

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]

This is the exact glue I used and we live in similar climates. amzn.to/3yFWSQ4 here is the boot too: amzn.to/3aOzBDR

[@flowerpower9541]

@@BryanHansen I really appreciate it, I had found the boot but I was especially concerned about the sealant. Thanks

[@job38four10]

When I put my chimney pipe up in 2015, I never heard of such a thing. You mean to tell me that rubber boot wont melt, I cant even put my hand on my chimney pipe.... In my shop I just replaced my chimney pipe with 7>3' sections of Selkirk chimney pipe on 35° metal roof similar to your stile. I have the same metal boot that you replaced and I dont like how seals either but I got it, I used the prefab metal roof foam top and bottom, painted wood slats down the sides there was. I had to replace mine after just 9 years, a whole nother story.......

[@BryanHansen]

@@job38four10 these are rated to 500 degrees Fahrenheit. At the stove mine is 400+, but 10 feet up leaving the roof, never over 200+. I do run class a through the roof, it’s never over 150 at that point, but yeah either way, rated to 500.

[@joshuamorris9050]

What temperature is the boot good for

[@BryanHansen]

392 degrees Fahrenheit

[@rockpaperflowers2181]

Hi Bryan, is a storm collar required with a silicone boot? Or is it more like- "could be helpful, why not!" thanks!

[@BryanHansen]

Definitely a “could be helpful, why not”. I had it off of the old one and decided to reuse it on this one.

[@MrSprintcat]

We always silicone the storm collars also. Good job

[@Cire3PC]

Are these only for steel roofs ?

[@BryanHansen]

What type of roof are you wanting to put it on?

[@MrSprintcat]

I think he has a glass roof😂😅

[@johnmatysek7102]

Where did u buy storm collar

[@BryanHansen]

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

[@badromenful]

Does the steel roof require 2 inch clearance?

[@JD-fo6gs]

No because it's not a combustible

[@ArchieLex]

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.

[@BryanHansen]

Not per the manufacturer.

[@MrSprintcat]

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.

[@fliple48]

With metal roof you need to seal it all around. If you don't water can slide in with the wind same for the ice and make lot of damage

[@carl8568]

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]

I have put a bead around it before. It is a tight fit, but it doesn’t hurt anything to put RTV around it.

[@carl8568]

@@BryanHansen Yes, for sure. I think I'll do that, cheers 👍

[@carl8568]

​@@BryanHansen Argh, I got a leak 😒

[@BryanHansen]

@@carl8568 coming down the pipe or around the roof seal?

[@carl8568]

@@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.

[@LukeAudette]

Double wall or Triple wall chimney pipe?

[@BryanHansen]

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.

[@LukeAudette]

@@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.

[@BryanHansen]

@@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.

[@jackktorness]

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

[@BryanHansen]

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]

@@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.

[@BryanHansen]

@@jackktorness it should all seal up. That’s why you use the silicone and gasket washer screws.

[@bw3506]

@@jackktorness Unfortunately when you go diamond pattern it overlaps more tall ribs. This in my opinion makes more areas of damming.

[@bugoutranch1313]

Awsome ! Which size did you order ?

[@BryanHansen]

The 7-13”. amzn.to/424VcgX

[@gregmorgan3308]

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]

Nope! Right from the manufacturer instructions: "Apply neutral cure silicone sealant on underside of flange"

[@JD-fo6gs]

He did it the correct way it's a high temp SILICONE boot SILICONE is what is recommended under the flange

[@BryanHansen]

Here is the follow up and what it looks like 2 years later. I burn coal and you can see the soot has made the orange black, but it is still sealed like the day I installed it: kzbin.info/www/bejne/aWKrgX2Hjb9qn7M

[@bksduskmirror1250]

Can you install thin on the peak? My chimney come out right on the peak and cant find a flashing that works

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
