- In this video we’ll show you how to install roof flashing around a chimney. Whether you are flashing the bottom, top, or sides of the chimney frame, there are different flashing methods that we use. The same process works when flashing around a skylight, so keep that in mind if you’re installing skylight flashing.
This video does not show how to install a cricket, we will provide those instructions in a separate video.
The methods of flashing a chimney that we show you in this video will ensure that the chimney is waterproof and won’t cause any leaks or roofing issues. If you’re a homeowner, we recommend hiring a professional, licensed roofer rather than attempting any roofing work yourself.

Thanks for watching, leave a thumbs up if this tutorial was helpful!
Hey guys this really helped me out as my hack "roofers" bailed on me. I have 2 skylights that have the step flashing and the one question I have is does the bottom solid Tin flashing go on top of the shingles like you guys have in your video or do I put shingles over that solid piece on the bottom of the skylight? I really appreciate any advice as some hack roofers took advantage of my grandmother so now I'm trying to fix the mess
This is by far the best video I’ve seen on this process ❤ y’all get straight to the point no BS. This system should last decades
Thank you! Glad it was helpful
You've saved my life once again, my friend. And tell Marcos thanks for being a faithful friend as well.
Will let Marco know, I’m sure he’ll be glad to hear. I feel like he is the unsung hero.
This is the best explanation by far from all videos. And not just this video all his roof videos i watched are better then anyone else. Thank you for doing this. You helped me a ton.
Wow, thank you for the comment!
Thanks for the in-depth videos. I decided to put my roof on myself so it would be done right. I'm installing O.C. Duration and find you follow their guidelines to a T and with some nice added touches I must say. Definitely the best videos out there.
Thank you, much appreciated. Hope your project is going successful.
This show is a lot better than the others and thay demonstrated the warter good job guys
Thank you.
Excellent video ... just what I was looking for ! Explained everything !
Glad it was helpful!
You guys do beautiful work! Thanks
Thank you too!
Now I can finally lay my shingles! great channel! greetings from Germany 👍✌️
Glad you like them!
professionals. Nicely done.
Thank you very much!
Nice. Hope you show the counter flashing in another video.
Hi, what about top of the flashings? Won’t water be able to make it in between the flashing and the chimney? I have a stucco chimney. What should I use to between the chimney and the top of the flashings to prevent water from entering?
good video
Thanks for the visit
This is the best video I have seen regarding chimney leaks. I have tile roof. Can you do a video on the same subject with tile roof ? Thank you.
I have one. Search the channel you should find it
11:11 the areas where Marco nailed on that rain diverter, I would also seal them with ice and water. I would put ice and water to cover those nails and cover the upper edge of the diverter to prevent any water from going underneath the rain diverter to the chimney area
Definitely wouldn't hurt
Very helpful video. Did you cover the installation of counter flashing for the chimney in another video? thank you.
Not yet, that is on my list of future videos.
Usually the orders to put the chimney shingles are front apron , 2 sides of step shingles then the back higher slope of back apron. If my chimney the highest slope point between on the left corner of my back apron and on the left top of step flashing, and also the highest point of my chiney hits the hip, what do you suggest to put the flashing order? same way? Do you have any tips for this kind of shingles order to set up?
Honestly having a hard time picturing your exact situation. Every job presents a unique situation that sometimes need field fabrication. The concept remains the same. Water flows down, top flashing or shingle on top of the bottom one.
3 nails on a step flashing? one of those nails are way too close to the wall as well which will cause a leak after a while
I put 1 nail in the top left corner and a little bit of tar to sit the step flashing onto the shingle
Ya, I think your probably right. It might be better just to do 1 or 2 nails all the way at the top.
where do you find your flashings or your 110 flashing for example?
We buy our flashing and actually all our materials from roofing suppliers. If you are in the US the 3 major ones are ABC, Beacon, SRS. Keep in mind the flashings and the names of flashing vary from region to region.
@@RoofRepairSpecialist thanks for the past response. We have ABC here in my territory
The 110 Metal, you're nailing into wood. How should one fasten if the chimney is brick and mortar ?
When working with Chimney's the best practice is to not fasten it to the chimney and just fasten to the roof. The reason is that chimneys are independent from the roof. There is actually movement that takes place.
Could you please call me I have dormor windows and don't know how to do the fasha board on top of dormor with starter strip and be able to put siding?
Hope our videos can help.
What type of sealant are you using?
We like using Chem Link M1 structural sealant. But there are plenty of other great sealants on the market
My garage has a chimney that has a box built around it that goes through the roof and one side is attached to the gable side of my house. So, there are 3 sides that need to be protected. Would I use this same method for my chimney?
The upper side collects debris. Not sure if its called a dead pocket or not.
No slightly different. We would build a cricket and give a slight slope. Approach with caution, that’s a tricky detail. I don’t have a video on anything like that
What size gap between shingle edge and step flashing?
I would say 1/4”
Is 4x4x8 step flashing adequate size?
4x4x12
Someone told me this is a lazy way to do roofing and should not be done as it will fail much faster than tucking the flash in the Chimney. Will you elaborate on this technique in that regard. Thank you
Not clear on your question. This technique is tucking the flashing under chimneys counter flashing.
Usually chimneys will have z bar.
why can't you use one full piece on the step flashing?
I think I explain it in the video but maybe I am mistaken. If you use one long L flashing
Water can go onto the shingles. When you use the flushing water roles back on top of the shingles.
Can you use metal bent at 120 degrees
That’ll work depending on the pitch of the roof, 10 degrees won’t really make a difference
Thanks can you use just a coil metal and bend it by hand estimating the angle
Do you work in Souther California
Only in LA County area. We are based in Burbank.
how do u air seal and insulate a chimney in the attic?
Not sure, that’s not something we have experience in.
@@RoofRepairSpecialist you should get some experience in it and post a video about it
Is there any reason why you don't use lead no cutting. All corners can be dressed or bossed and will last 100 yrs
That's definitely a solid detail. I think it's overkill in our area, however if someone does do it it'll definitely outlast the roof.
i really like the step flashing / .. ( i know that's what's missing on my roof.. and MY QUESTION is.. is there a way to fix that.. ( instead of that ( long L piece) .. ( with out taking off the (hardyboard) siding now? ... gez THANKS!! (cuz YEAH, if you are redoing the whole roof.. and taking up the siding and all.. 'it's easy to redo' at that point'.. but your throwing 20k into it... hahaha ( when it's a 20$ piece of flashing right.. lol .. idk.. ( no point in putting more 'tar or elasto- STO over it i guess... *shrug
Thats a tough one. there is a way to retrofit it, a little hard to explain without a video but I'll try. Essentially you cut the bottom 6" of siding without remove it. Now you have a 6" gap between your roof and siding. At that point your able to install step flashing as needed. Then install Zbar if your able to , if not just install a 1x or a hardie 1x and caulk it.
he nailed WAYYY to close to the curb, guaranteed leak
I guarantee you don't know what your talking about.
The roof shingles are going to come from the roof down on the dormor top no flashing on top edge of dormor.
Not sure I follow
Chimneys are brick? nails in brick?
You can mail in roof only, no need to nail to chimney.
Cant believe you don't use even a hand break
lol, unbelievable
Terminology is confusing here. Saddle flashing is another name for cricket flashing. You installed flat head flashing on here, but kept calling it saddle.
Saddle is different than cricket. Saddle is just flat, crickets divert water.
Front pan &
Back Pan.
If you have a chimney, get yourself a CHIMELLA you will save Hundreds per year on your energy bills
Thanks for the spam.
So a couple of quick points. Not sure why you would install a saddle flashing component WITHOUT a cricket, that’s a huge professional Nono and long term, not a good solution. Second, why on earth wouldn’t you GAF StormGuard, ice water barrier BEFORE any flashing installed. These steps are rudimentary and almost apprenticeship level steps! Overall, not a bad video, but certainly I wouldn’t pass this as an “expert” install.
1) We install crickets on chimneys wider then 30”
2) I’ve and water shield is optional and not required especially in areas that don’t have snow and ice damns.
Any roofer should know this
This will fail during heavy rains.
Why? How?
That first step flashing ugly bro
Looks good to me
You guys need to stop roofing
Will do.
Great work. The roofer I hired did a less than satissfactory job around the Chimney. it leaked. When I contacted him, he said 'that chimney stye is difficut to work with.' I Replied, Then why did you not say that before taking on my roof replacement? No answer. Just a not good contractor.
That’s a bummer
Sice the 2020 'crap' that was pushed down our throats, I now trust no one. Sad, but True. Best wishes. . @@RoofRepairSpecialist
