How To Shingle - Step Flashing

A few issues to point out Shannon: 1. Never metal to bare wood. Always put in a vapour barrier on the wall before the metal is installed. Avoids sweating 2. Nail the steps to the roof top outside corner. Nailing into the wall could cause buckling as the roof and wall move differntly in warm and cold weather. Also gives you the possibility of making step repairs in the future as the nails are accessible and not hidden behind the siding. 3. Leave a 1/2' to 3/4" gap ( I use 1/2" gap ) between the shingle and previous step ( channel ) to allow water to flow though and prevent blockage from needles or debris 4. The bottom wall flashing ( not the step ) should wrap around the wall and it's bottom leg should extend out under the step above it . I just remember metal should seam up to and overlap metal 5. The very bottom step flashing should extend out at least four inches past the bottom. You might need to use 2 steps to make this work I think what you've suggested would work, but there could be future problems. I'm a roofer here in Vancouver. Great work on all of these roofing videos.

[@HouseImprovements]

Thanks for the tips" coffee troll ". I have one question ,when you say vapour barrier do you mean a membrane material or even a strip of house wrap? I would assume so as vapour barrier would not be on the exterior.

[@CoffeeTroll]

A strip of house wrap would be great. I turn my underlayment 4" up the wall to get the same effect as suggested by seephor in the comments below.

[@bigal9940]

Just a point on your second issue about nailing to roof instead of wall. Great in theory, I learned this also but not realistic simply because when you nail the j-trim on the wall to catch the bottom edge of siding there will be plenty of nails through the step flashing and into the wall. I usually use a self sealing membrabe on the wood first before the step flashing goes against it.

[@ozziestrom9793]

WE INSTALL THE J-MLDG. but only with one nail at the far top left or top right end of the channel depending on what side you're going up the roof. By doing this, only one nail is going through the step flashing eliminating possible leaks from nailing down low into the J-mldg. slots. When the siding is installed into the J- mldg. it actually holds the J in place against the wall. You can also run a bead of compound at the base of the J as an extra precaution. We've been doing this for years, never had a call back..........We also install the ice-water shield where needed

[@CoffeeTroll]

Love hearing about thoughtful methods like yours ozzie. Thanks for the tip.

[@kattay3465]

thanks for the video. one suggestion; there should be a strip of building wrap/paper under the wall and step flashing protecting the sheathing from condensation behind the metal. The above building wrap then laps over the flashing as mentioned.

[@kenhughes186]

Thank you for taking the time to post this video! It was very helpful. I'm confident this is the source of a persistent leak on my roof where it meets the chimney.

[@johnburns2940]

Dude, did STEP FLASHING, solve the problem around the chimney?

[@huejanus5505]

Always easy to do proper flashing on new construction, problem is most of us are reshingling a house, and in my case, there’s a layer of 1” insulation, strapping and siding already over the sheathing.

[@Amunra-h4x]

the gaf videos recommends to nail to roof only , never to the wall. and I think it makes sense. flashing is a piece of roof( it gets glued by shingle too) system and should remain with roof body, while the walls/roof junction moves.

[@ericnagy8056]

Wrong

After we moved into our house a couple years ago that we had a roof leak and what happened was whoever did the roof did not put flashing up at all....very frustrating to deal with.

[@dsbradley018]

They make a corner flashing that you can use on outside corners like this. You can form it to the corner and it is the best $1.50 you will ever spend!

[@mikehikes710]

Or use lead

[@scottdowney4318]

My house made in 1973 with aluminum siding would be very difficult to do flashing the way your saying. You dont just remove the bottom levels of aluminum siding, they do not come apart like that without ruining them, they would be bent. I am going to reroof as it was previously done by roofers, angle flashing slips up under the existing siding with no J channel and is left loose on the wall, not nailed. It is still nailed thru the shingles. On a wall with a slope, siding is loose along the edge and has room to slip up between siding and the wall. I have repaired an upper story corner of the house above the large 24" wide overhanging soffit on a sidewall. I removed the siding and used 1/2" plywood. I used Protec 200 from the small roof section going across that soffit roof and up the wall 2 feet. Then used a drape of Protec 200 to go down the wall overlapping the underlayment that came up from the roof. So in the corner where wall meets roof is solid fabric underlayment. I am going to flash with 7" by 8" pieces cut from a 14" by 50 foot trim coil. It is better than what was there, no underlayment wrapping, and angle flashing was 2" legs and 6.5" length and lousy exterior broken apart sheet rock sheathing.

[@Smpl97]

Thanks for your video. I like your videos all the time and I'm at home inspector. I don't think so, We can put a nail on the surface level of the step flashing And you have to put the building wrap under the roof covering materials. This is a defective job

[@alm7707]

Great info, I have to do this. Why would you leave the bottom longer than the shingle so you see the edge, wouldn't it be nicer to hide the tin?

[@brownitsdown]

it lets the water take that longer edge and run off better, its there for a purpose

[@fisher9915]

I have to disagree, you should never nail thru the step flashing. You can adjust your shingle nails over to keep from nailing in the flashing.

[@johnburns2940]

I appreciate your caveat and will think on it. Would you, spot glue it or caulk it to hold it in place until the shingles' tar, locks it down? Certainly a nail through the flashing is the last resort.

[@nejolo9563]

What if the roof is already done and you need to put flashing on a roof window. Will contact cement or a caulk suffice? What is the best option? I’d rather not nail but if I have to I’m thinking only the upright portion of the flashing.

[@chadziegler7292]

So why step flash when you could run the head wall as one piece Also you didn't leave a water channel like half inch gap to give the water space to get off the roof instead of under the shingles also roofing cement last forever if it never sees the sun

[@RobXb]

Yeah no seen so many roofs with the step flashing causing the shingles to lift up and it looks horrible all cause they weren’t nailed.

[@Gadfly321]

Yes avoid nailing the step flashing on the roof surface, nail the vertical part of flashing along wall only

[@waltermatthewberg]

I kick the roof-to-wall past the corner a few inches then fold the side. Trace the angle on the step and cut it off even but leave a little kick out on the bottom to shed water. You can put a little goop in the very inside corner. I don't leave exposed flashing because it looks ugly. Don't nail the step too close to the wall because it may leak and maybe leave a 1/8” or 1/4" gap for water to flow on the path of least resistance

[@a191015]

Thanks for using the model. Makes it easier to understand👍

[@Brandon-no3vc]

Dont you need a 1/4 inch space between the shingles and the wall for expansion ?

[@R90916]

I like to put a dab of solar seal under the shingle and flash card! I use one or two nails as far from the wall as possible and squeeze a little muskrat oil for extra protection!

[@eddiegreg7064]

Why doesn't your front pan extend onto the roof nor wrap around? Thanks 🙈🙉 🙊

[@mercilesstango2701]

Prior to this video (pretty basic stuff) gents, remember to run your underlay up the 90s. I prefer to run min an inch or so higher than the height of the step flash, this gives that nail a second job, additionally securing the underlayment. Wrapped outside corners, always the way to go.

[@paulinemarr586]

Thanks for this video. Makes perfect sense.

[@Dave-jc6ky]

HI, I am trying to estimate how many pieces of step flashing per linear foot or per shingle. I know this may depend on actual width of flashing. Though most pre-made step flashing appears to be 5 x 7" which doesn't provide much rise against wall behind siding material. Also I see some allow more overlap of step flashing across the top of the shingle and prior to the next end piece of shingle is installed. Your input is appreciated.

[@timbibin1301]

2 pieces of 8×8 flash cards would be needed for every linear foot of shingles

[@ryanthibeau6586]

Put ur nail at the top of you wall side of step flashing that way your next step covers the nail so they are covers the whole way up

[@mattomite9097]

Thank you! Your videos are always so well done and helpful.

[@morokeiboethia6749]

Question - when the shingles are meeting a wall on the "north" side (the side of the shingle facing ridge) of the shingle, L-shaped flashing aka "headwall flashing (continuous)" is used, and one lip of the flashing goes behind the siding of the wall and the other lip of the flashing goes on top of the shingle. Then another row of shingles is installed on top of that lip of the flashing to hide the flashing. How is that final row of shingles attached on top of the flashing? I was wondering this b/c if you nail the shingle on top of the flashing which punctures the flashing, there will not be another row of shingles to overlap the nail and direct the water past the nail like it does in the sidewall/stepflashing. Do they normally just use an adhesive to attach the that final row of shingle on top of the flashing? In your video, the shingle meets the wall on the east side of the shingles (sidewall connection) and nailing the shingle into the step flashing is fine since there will be another run of shingles overlapping that nail a few inches and directing the water past the nail. I understand I'm talking about a different kind of flashing and wall connection but I have only seen pictures of how headwall flashing and shingles should be layed out but none of the illustrations I've found show how that final row of shingles that are run on top of the headwall flashing should be fastened.

[@HouseImprovements]

You would install an apron flashing over the last row of shingles. This is normally a coloured metal flashing ,maybe 3x3. It goes under the siding materials and is nailed to the wall while the bottom lip extends out over the last row of shingles and covers the shingle nails.

[@stumpynubs5387]

Which flashing hold up better? Aluminum or galvanized?

[@tonybenjamin7844]

Why do you leave some of the metal step flashing showing instead of hiding it under the shingle?

[@HouseImprovements]

You dont need to that is just how I was shown to do it.

[@jim77004]

Everything I've read is that step flashing should be nailed to the roof like a normal shingle, not to the wall (read that it can buckle). Most skylight manufacturers recommend roofing tar with each course as well. Why do you recommend nailing to the wall? Cheers... you have great videos.

[@ericnagy8056]

Flashing on face of dormer should wrap around corner and 1st piece of step flashing should wrap around front. Do not strip siding unless necessary. Inflated labor cost for homeowner. Dont leave flashing exposed. Nail Flashing through roof( always a chance shingle could lift because of expansion/ contraction). Ice and water barrier under all flashings. Just some tips from guy with 45yrs experience and counting

[@seephor]

Good video once again. Question: If you were doing a new construction home that had no siding or if you had removed the siding, would it be a good idea to run the roofing paper up the wall about a foot just for added protection in addition to the step flashing?

[@kernjames]

[@ClintUmbrell]

Thanks for the education. What is the advantage of step flashing versus one long solid piece of L-flashing?

[@HouseImprovements]

The step flashing helps direct any water that gets under the shingles back out on top of the next row right away a long 1 piece length has the water flowing down it a long ways and more chance that that water will creep sideways and off of the flashing on to the roof sheathing before it ever gets to the bottom of its length.. This make it less likely that you will get significant damage .

[@nejolo9563]

What type of adhesive will work if you prefer not to nail the flashing? Contact cement or caulk? Will it hold the flashing in place?

[@HouseImprovements]

adhesive won't do the job on its own.

[@andrewlee6184]

Would it be okay to run a bead along the side of the shingle to ensure water doesn't somehow get underneath?

[@HouseImprovements]

The whole idea of the step flashing is to direct it back out onto of the shingle below if it does.

[@yogibeer9319]

Awesome video. Why is step flashing better than a long solid piece of flashing?

[@HouseImprovements]

With a long single piece the moisture that gets by the shingle to the metal just follows it a long ways down the roof and sometimes just rolls off under the shingles to the roof decking. The steps allow moisture to only travel a short distance and its directed right out onto of the shingles again.

[@MayonR]

Put a roof-to-wall (the front L-metal on video) up to window flush to the window. So you might have to cut it to size. Wrap some to go around a corner or seal generously. 2 inches should be enough to get away with on a pitched roof but more would be better. You can caulk the edge that ends at the window to avoid leaking.

If you cant get it to bend enough to stay down I would first try taring the crap out of it and putting some weight on it for a few days to see it that will hold it down. If it doesn't work a nail may have to be used.

[@GeorgeMinton-jb8ky]

Why do you nail the step flashing so close to the wall? Wouldn't the water most likely be right along that edge?

[@blackstaticband]

why do you need step flashing vs 1 large L flashing instead? Is it because it would stay under the shingle until the end of the long L?

[@HouseImprovements]

Step flashing will direct any water that gets under a row right out instead of one long piece that does not direct the water out until the bottom giving that water more chance of rolling off the step flashing and into the roof underlayment.
