- Welcome to Schoen Roofing!
In this video I demonstrate how to install step flashings along a wall. Step flashings are an integral part of a wall detail and need to be installed properly.
I have seen numerous roof leaks caused by the improper install of step flashing.
Even worse I have come across may leaks where there were no flashings!
Thank you for watching this video, it means a lot.

your nail on first shingle nearest the step flashing (the 4th nail that is closest to the wall) will be a leak after it rust from water contact. The seal down strip on the bottom of the shingle will seal to the step flashing and direct the water over the step flashing onto the shingle nail at the outer edge of the step flashing. This would not be a problem with 3 tab shingles as the seal down strip is above the shingle exposure. Good practice of no nails within 6" of the step flashing would solve this issue.
The first step shingles you installed is suppose to divert water away from the wall.
Yes there will be a kick out flashing installed when the new siding goes on later this year.
@@schoenroofing later? What's you talking about?
dont water go behind the step flashing along the stucco wall when it rains?
I never put any nails in the step flashing on the roofside. That's where they all leak .
Do you have the next video that would show how to install the counter flashing on the stucco walls? This is incomplete and therefore confusing to newbies.
Unfortunately we did not record that process.
Your step nailqpattern is wrong, by placing the low nail below the overlap of the step above it you keep an exposed nail where the water diverts potentially under the transition area, under the shingle. Snow build up in the wrong area would also be an issue, if the roof attic isnt properly insulated...just sayin
You are not incorrect. I find this pattern helps keep the step flashing flat and therefore lets the water flow downhill instead of sideways.
All wrong. Lol. The stucco should be your counter flashing. Stucco is porous. The water should weep out onto the step flashing. Not behind. To do this properly, you need to cut and repair the stucco.
They will be siding over the stucco in the near future. You are correct and I should have mentioned that in the video. Thank you for pointing that out.
Yes, needs Z metal
@@schoenroofing Yeah Kinda important detail to overlook
I know this is a year old comment but I can't find a video of doing your method! Help please
Ive been running the electric dewalt nailer too😎 so convenient for metal install 🤘🏻
Oh baby, Its my 3rd child
Until it hits the ground. I'd rather have the air hose.
So there is going to be siding installed to overlap the vertical seam. That makes sense now. Thanks!
What is stopping water from going behind the flashing since the wall isn’t flat?
We installed a counter flashing over the step flashings. Probably should have mentioned that in the video.
I'd like to see how the counter flashing gets installed.
I can't wait to see the counter flashing installation.
@@schoenroofing so the counterflashing makes some sense, but you will still have a smooth surface (flashing) against the rough stucco wall. do you just caulk the daylights out of all of the gaps and hope for the best? the stucco on my house is very similar and I'm not sure what is standard practice to do.
@@schmitty69 You can caulk the daylights out of it. Better option is when the counterflashing is installed it should be cut into the stucco. its called a reglet detail and I have a video showing how to do it in brick. Hope this helps!

To me, Flashing always seems to be inherently flawed to me when its designed to allow water under a shingle. It exacerbates all sorts of installation errors which seem to be common place. Even the install on this video had an error according to some.
Thanks for your videos.
So how do you seal the step flashing to the house?
We installed a counter flashing over the step flashings.
You need kickout flashing
The only thing he does right is when he adjusts the bend in the flashing so it lays against the wall.
step 1. lay flashing (don't nail)
step 2. lay shingle over flashing (nail through shingle and flashing)
step 3. place flashing (don't nail)
step 4. lay shingle over flashing (nail through shingle and flashing)
More than 1 way to do things.
I’m confused there’s step flashing but where’s the counter ? And where’s the kick out ? lol
Good question. Both were installed after.
😅🤣😂 you are NOT roofer sr
Yes )) it just for the video
That’s a soaker, not a step flashing.
Where is the counter flashing? There doesn't appear to be enough overhang not to use it...
Counter flashing was installed but this video was just to show the step flashing process.
Our you could use a flash right
Great job man. It's hard first starting out doing videos. I love how you make a mistake, you catch it, own it and fix it. Great work
Thanks Shaun. It is hard to explain what you are doing while trying to keep it simple and digestible and not make a mistake.
Good work caveman 💪💪 that was a sweet detail at the top
Thanks Andrew!
I have a question, what cocking do I use for metal and with stako?
I always use Malco Supra.
I don't understand how water doesn't go behind the flashing and the stucco?
There is a counterflashing that gets installed on top of the step flashings.
What if you don't have siding going over top what do you recommend?
If there is no siding I would install a counter flashing.
Is flashing 4 x 4 x8 ?
Yes I believe so
How much would a job like this set you back for? Just noticed a water damage spot on the ceiling which appears to be where the second story wall meets with the garage roof. I do not see flashing there.
Cost would depend on the scope of work. Sometimes shingles need to be removed. I would get 3 quotes and go from there.
shouldn't there be a kickout flashing at the beginning?
Absolutely. The company installing the trough on this job has their own diverted they like to use so it colour matches.
We just uploaded a video on how to make a seamless kick out flashing. Thanks for the question!
Is there going to be another metal flashing on step flashing? wondering if you have a video. Sorry, I am so new, never install this.

This video will show something similar that would go on next.
@@schoenroofing Thank you for the tip and your video. Really appreciate that sir
Also, do you have a video how to cut the line on the stucco wall?
A great ideas
Where are you located??
Hi. Thank you for the comment. We are based in Souther Ontario, Canada.
Excellent work!
Thank you for the kindness.
I have a sunroom that i want to gable roof with an extension room i saw that you did exactly what i am going do you have a video for that
Do you mean how to build the addition?
@schoenroofing yes I am going to turn it into an extension room.
@@leighton999 I do not have any videos of framing the structure. If you search on TH-cam I’m sure you will find some qualified framers who share their talents. Good luck!
Should the nail heads fastening the step flashing be sealed with caulk or a sealant?
You can if it makes you feel comfortable but is not necessary.
Search up "blind nailing step flashings"
Where's the diverter? If you start your starter from the opposite end chances are you can still run full first shingle.
excellent demonstration
Thank you! Cheers!
Water will still get through when it is very windy. Water will come all directions. You should have counter flashings as well.
what about any rain that gets behind the step flashing ? should the back to the wall have been sealed ?
Hi Danny. We installed a Counter flashing over the sterps. Did not get around to filming it but will make for another good video. Thanks for watching.
@@schoenroofing you should link that video... Without that it's useless
I dont think this bloke knows what he's doing!
Over time, i've paid £1000s for my flat roof sorting.. last one £6000 or so....and not one of them cut a chase in the wall, consequently, as the roof is subject to movement, the seal (butt up to the wall) just comes away..seal was concrete. I said he needed to cut a groove in the wall to insert some kind of flashing...nah..it'll be alright this way 😡 I've had to keep sealing it again myself as he can't come till after New Year!
There will be a counter flash added up the wall usually secured with one shot or concrete screws then on the top of the counter flash there usually a spot to run a bead of caulking!!
Diverter first and I would never have srep going up a stuccoed wall
So what happens to rain that hits the siding above and drains down the wall and behind the step flashing? Usually you overlap siding over the top of the step flashing, but in this case the house is already "sided" so there's nothing going over it.
Hi! Thanks for the question. We installed a counter flashing over the step flashings to keep water out. One day I will make a video showing that process.
You don't need counter if you put one nail high on wall. You're just adding to the cost.
@@highnoter1 Not true. You must have a lot of leaky walls if thats what you do.
Dont you need a 1/4 inch space between the shingles and the wall for expansion?
You are correct. We leave a 1/4”-1/2” gap between the shingles and flashings to allow for shingle expansion and to give the water an unobstructed channel to flow downhill.
@@schoenroofing what if shingles are already expanded?
@@Brandon-no3vc Still leave a gap
@@schoenroofing shouldn't need a gap should you?
@@Brandon-no3vc?
What do you do if there’s already shingles?
WRONG that will leak and fail.
No good roofer uses a gun
Hi can put a flashing over the shingles cause I already have the shingles on?
No. If you put flashing over the shingles, water on the roof would run right under it.
You can remove a few shingles and install your flashings. The shingles and flashings have to overlap and alternate as shown.
So you cut the underlayment everytime you cut a shingle?
Hi Chad. We use hook blade knives so it keeps the material raised and does not cut what is underneath.
You never nail through the tin shingle into the roof. You better learn how to do things right
Sometimes you can nail to the wall, many times you can't. What then, no step flashing? You put the nails high enough to be well covered by the next shingle and flashing.
Exactly the same as you nail shingles.
the grey beard says old school but your technique says Rookie. one nail on the wall will hold every one just fine if its getting siding later then you wont have nail holes leaking thru playwood in heavy rain and wind..... and FFS i can hand nail faster than that slow crank engine nail gun that drives ur nails too deep almost right thru each shingle does. Get it together My Guy!!!
oh and you quarter shingle stagger!?!? ooof.......
Lol. Thanks for the comment.
So you nail all your steps into the wall so they can never be replaced? Great idea.
As far as hand nailing, you do what you feel comfortable with. It’s not always about speed my friend.
Lol.... may be I am wrong. your first #1 piece of metal flashing support to go on top of the shingle and not on the bottom ?
We want to keep all the flashing hidden so this is the procedure we use.
You for get the kikcout
HELLO
Nope.
Lol
How do you create a seal between the plates and stucco?
We installed a counter flashing after these step flashings. Im hoping to make a video showing the process.
Thank you. I didn't realize multiple peeps asked the same question. Apologies.
Thank you!!
👍👍
What do you use to seal the vertical seam where the flashing rests against the masonry wall? on a sided house, this seam would be behind the house wrap and siding.
Thanks for the comment. There is no need to seal the vertical seams on the steps as they overlap each other. And you are correct that house wrap and siding would come down and cover almost all of the flashing.
@@schoenroofing Really? Seems like when the rain hits the wall, it will go behind the flashing.
@@Rich-hm9ux Hi. There is a counter flashing that goes over the step flashings to prevent water entering from the top. This video was only showing the step flashing install.
water or condensation can get in the holes where you drove the nail. It is necessary to use seals under the sheet metal
The idea is to put the nails high and outside (away from the wall) where they will be covered by the next shingle and flashing. It's time tested and works.
If you're super worried about it you could use a small amount of sealant only where the nails go, but it's really unnecessary. And if you use a lot of sealant/caulk over your step flashing, you defeat their function. Water that gets behind the shingle edge needs to flow out on top of the shingle below.

Metal is permanent, goop is temporary.
Shingles, what a horrible system of roofing 😥😥
What’s your roof product of choice?
Sorry, but this wrong. The nails in the flashing belong on the wall not the deck. The nails in the shingles will hold the flashing down. Doing it your way introduces more holes you don't want.
Thank you for the comment. This install method is not wrong. You need to choose the wall or the deck to secure the flashings with. As long as you don't nail both you are alright.
Nope. You are wrong. Any roofer that knows his stuff would agree.
@@highnoter1you are wrong bud. He is doing it right. GAF states you nail to the deck.
@@highnoter1What about when you can't nail to the wall? Then you have to nail to the deck. You put them high and outside, away from the wall, and will be well covered by the next shingle and flashing. Exact same principle as nailing shingles.
Forget the step flashing unless you have something to go over the top of it like siding. Otherwise i would cut a reglet and have a continuous flashing.
No. Don't do that. You add a counter flashing over your step flashing. That can be continuous, and have a reglet if appropriate. But you need the step flashing under the shingles to kick the water out over the shingle below. A continuous flashing won't do that, it keeps water under the shingles where it can then run back under the flashing lower down. It will eventually fail.
You could have just flipped it over when you cut the wrong side
What? No..

Definitely not
