HOW TO LINE UP 2 SIDES OF A CLOSED VALLEY

In this video I do a detailed explanation on how to line up 2 sides of an open or closed valley on an asphalt shingle roof

[@2112Primus]

man i don't know what i would do without this channel i'm redoing my roof on this old as hell house i bought, first time ever roofing and i hate this crap so much man🙏thank you for making these videos for idiots like me who think they're hard enough to roof their own house you're a godsend dude

[@BWeezy-sw1wy]

I’m finding this out too, but learning how god awful this work is to do in the summer; almost by myself. Problem is having to learn it without someone there telling me what to do a few times. I just shingle one side of my porch and once done I noticed I have a varying gap to the peak. I think nobody will notice but the next roofer, hopefully when I’m 70.

[@matthewasti5821]

I decided to save myself a fortune and do my roof myself (limited roofing experience in the past), your videos are the only ones I used. You're a good teacher, thanks for your help.

@@Lifes_Apprentice I'm not going to say the way I do it cus your just going to ridicule the method.. all I'm saying is you're telling people to do it a way that you think is easy and it's not, it's easy to you because you've been doing it..

[@Lifes_Apprentice]

@@pimp1979robertmack It is easy if you can do basic math. You probably shingle out of the second valley from the top down and then shingle as normal. I do that too but that isnt how you teach people on youtube

Ummmm each line should be 45. Or 22 and a half

[@douglascunningham148]

It's 5 5/8 reveal, just like it says on the package. I use theses shingles " certainteed" exclusively. Like millions of dollars a year. I have 5 other guys that I work with

[@gregwawryk1898]

About 25 years ago I started weaving all valleys. Never had one leak ever. Thanks for the video.

[@GVPARTS]

Exactly the info I needed. Thank you.

[@Shryquill]

Nice video! The way I like to handle these is to snap a reference line parallel with the main ridge, at a height of a few feet above the intersecting ridge. I then shingle both sides up until they're 5 courses below the intersecting ridge height. Take measurements of both sides against the reference line, and with those 5 courses of space I can drop either side up to 3" with ⅝" drops, which is enough to bring shingles into level even in the worst case where they'd otherwise be half-height out of phase. There's a little bit of math, but it's fairly straightforward when you see it being done. Bonus tip: for the last course before merging, only use 2 nails at either end of the shingles, work out where you'll want the merged course of shingles to be positioned, then fill in the rest of the nails, respective of where the keyways of the next course will be.

[@michaelhilber8284]

Good job. The back of my house has no valley, but the front has a small one because of the roof over the front porch. Measure down from the ridge. I've already shingled the back of the house and I did measure down from the ridge doing that because I wanted to adjust where I started the first course a bit so the top course that gets capped would have a reasonable looking exposure. Now I tackle the front with a couple small closed valleys. Actually my very old house, the ridge has a bit of a sag in the middle. I measure down from the ridge at the ends of the ridge and snap lines all the way across. I will rely on your video on how to lay the shingles for the closed valleys.

[@davidbrakefield188]

Chalk a line for the starter. Chalk a line for the first shingle. From the top of your shingle make marks 11 1/4 and 22 1/2 on most achitect shingles. Chalk lines all the way up both sides. The line should be the same unless you make a mistake making your marks.

[@elguanaco2692]

Good work 👍🏻

[@wdkofc6989]

That was a great video. I would hire you if I could.

[@baltazargaspar8233]

Great work, The only thing I’m against is speed valley due to the fact your coming short on your key way steps there looking like 3 to 4 inch stagers. Closed cut allows you to control your steps. Here in Canada that roof will leak over time due to ice and snow. I do a lot of valley repairs for this reason. Cheers and keep up the hard work!

[@richardmitton4115]

On that roof slope, I am not against his choice to let the valley dictate his set-back pattern. It looks to be around 5 plus inches? That would work in my region. What I don't like is the California Cheater Valley method. I've been roofing in southern california since the late 70's and hate that detail! Snap a line and do a real closed/cut valley!!!!

[@Lifes_Apprentice]

Thanks!

[@AdanAveytia-s6t]

I always use 22 1/2 or 45 just so my shingles wont show white line. And my valleys i raised them two at a time to keep em straigth. But good job looks good.

[@tr4v3sty420]

Absolutely correct 💯 22 1/2 , 45, 67 1/2, 90 and so on. Every fourth shingle will hit the line on the top side of the shingle. That fourth course will seemed dropped but true and straight (plus it covers that low nail ya just laid on the 3rd🤣). But first if you measure 13 1/4 inch from the edge of your gutter apron on the eaves bottom edge across the roof gable to gable, gable to valley etc. Then off of that line use the 22half,45,67half,90,112half THEN you have a recipe. Do that stuff and let me know how it goes for you. 👍 you be shooting lazers every roof.

[@VanSantHaus]

Hey do you have a video on doing the slope from beginning to end? We are planning to shingle our roof in April ourselves and I was going to take out porch roofs off to avoid and valleys but not am thinking about keeping them but I don’t want any chance of leaking in the valleys do to lack of experience. I found a couple videos but non on how the shingles at top of where two valleys meet should lay

Is there a way to avoid back stepping the stagger of the shingles in the valley?

[@D1andonly4]

Hello, for the valley. Do you go up 12 inches on the higher side of the roof? Does more of the shingle have to be on the higher side or lower. Some people do it differently, thanks

A question that you might have a fair answer to. As a home owner, hiring a roofing contractor, how much of what you teach in your multitude of very helpful videos, would it be whize to ask about, or have put in a estimate/quote?

[@brandongarcia3725]

You said the shingles you where using where 11 1/2 inch wide and you multiply. What do you multiply? Sorry may be a dumb question but I’m trying to figure out what you multipled

You are right, many people mistake for the roof

[@donaldphelps7867]

Bro am I smokin crack or do u have ur valley started backwards . I was taught to weave in bottom 2 rows. Then run ur lowest pitch roof , smaller roof , then run ur cut side , bigger steeper roof last

[@blake3646]

What's the purpose of running that shingle long ways all the way up the valley? I've been roofing 21 yrs,I no every1 has different ways of nailing,just couldn't figure out what that shingle would do other then having something to line your valley shingle to,an then you don't have to cut your valley shingles at the end ..what area is this in

[@Lifes_Apprentice]

WE are in wisconsin. This keeps it straight and prevent having to cut any shingles

[@VictorMendoza-p2y]

Okay thank you so much friend

[@carlandrews5810]

I got a question about roofing, dormers, etc. Any reason that I can't roof a dormer that dives into the main roof about half way up the main roof, before the lower parts? Just worried about tying it all in

[@gibsonbuilds4841]

Good job. My only suggestion would be to chalk lines right from the start. That way there's no fudging a little here or there. Ten minutes in the beginning will save a lot of .... thinking and talking with the crew in the heat of the battle.

[@markritchiejr4068]

What size blue line up from the row?

[@STapia-hf7vp]

Start like you always do, off the left side so you can use the gun to gauge and staple like no tomorrow. When you get to the valley just cut material so you are about one and a half to two tabs away from valley. Keep slot out of valley.

[@richarde7649]

Just a question, why not use the one inch spacing from the end on the first nail staring from the valley? Is the nail not covered by the next shingle sloping further into the valley? I was just thinking about the corner lifting? Sincere question, I would like the understand the reasoning?

[@natto_4]

On a closed cut valley like this (California cut) you want to put your valley nail no closer than the diagonal bleeder strip nail line. It will be closer to 4" from the edge of the shingle and the glue line will bond the shingle. The bond/glue is what really helps shingles from blowing off once they have had a day or two of sun on them

[@BillSch]

Easy to do with dimensional shingles. Try it with t loks.

[@corymesser1569]

In the valley you have shingles running up to the peak then run your shingles to it, what’s the difference and the advantage of doing this instead of just popping a line and cutting them?

[@Lifes_Apprentice]

I do not need to cut 40 feet of shingles in the valley????This is easier and faster

[@janellegrieco6077]

It looks like the ice and water shield is underneath your gutter apron in your next video I would put the ice and water shield over the top of the gutter apron! Otherwise, it’s a very good video

HELP.. Could you explain how to join shingles on a four way intersection connected at the same elevation.. one ridge is 12 12 the other is 6 12.. I put new dormers in a 12 12 roof, the dormers are 6 12 but the new ridges come together at the same elevation.. Thanks so much for your help!! I did subscribe!!

[@VenusMilan]

😊😅😊😊 great 👍😃

[@joerobijr]

So... the rest of the roof above the dormer just get ran from left to right like normal?

[@Lifes_Apprentice]

yes

[@natto_4]

These "speed valleys" on the left side of the dormer can be a nightmare for newer installers changing up their normal nail pattern for right handed installation. 99% of the time we build books up the right side on the left side of the valley and might need to piece in a double knife (15") shingle running into the valley

[@Atownshottas]

The quality of your work is spectacular sir 🫡

[@adamlynch7005]

Fantastic. I always view shingles as exterior trim. There's nothing uglier than shingles at cap with a one inch real on one side and five inch reveal on the other.

[@davidbrakefield188]

Sometimes you run into a crooked house where your lines are off no matter what you do.

[@Brandon-no3vc]

So you went streight with the ridge all the way down to the eve? Doesnt that make your reveal at the eve rally crooked and all the way up the roof just to make your ridge reveal streight and parallel???

[@Lifes_Apprentice]

If the house is out of square really bad. usually it is only an inch or two off which is very easy to hide over the course of the large run. The most important part to keep straight is at the ridge. If you are an inch or 2 off on a large side you will not see it

[@Brandon-no3vc]

@@Lifes_Apprentice what do you mean it's easy 2 hide over the course of a large run? Dont you start to tilt it a inch or 2 at the very 1st eve shingle? Idk I think it would be very noticable, you should make a video about this

we never do. I have never seen another roofer in my area use them either. I have torn off one roof in my life (3tab) that had rake starters. I have done thousands of roofs. Never had a single issue

[@Lonestarexteriors]

There should never be an issue, the reason why I do it, is because I overhang my shingles about 3/8 in on the gable and the starters keep it nice and straight.

[@Lifes_Apprentice]

@@Lonestarexteriors We install D-edge and cut to that and it is just as straight

If you do it like that, it leaves a space on each side so you can run the next row either way and not have a nail in the seam. I like 1, space, 2 3 4 5 but sometimes you gotta change it up near obstacles and edges.

[@808airgunsbackyardaz6]

Thx very detailed

[@shawncummings4653]

I can tell you the best way to have your rows at the top of the dormer comes out perfect, but is old school and not many roofer take the time or effort to do is to back down the opposite side. Not hard and your rows will come out on the money.

[@joerobijr]

Here's a dumb question...where/how do you start the very next run after the video ended? I ask because it seems like your going to run into 2 different nail patterns on each side of the peak. Plus adding that small piece at the peak seems like its gonna throw things off. Good work BTW. Just asking so I have an idea when I have to do mine.

[@Lifes_Apprentice]

yes you will have a different nail pattern for just the one row of shingles. If your nails end up in a bad spot when you run next row just use some sealant on that row

[@amandacarroll9611]

Life's Apprentice I had the same question using 3 tab. I'm wanting to replace my roof myself but a little worried about that part.

[@Lifes_Apprentice]

Same thing with 3 tabs... layout is a little different but pricipals are the same

[@dbarr8261]

​@amandacarroll9611 For 3 tabs you have to stay with the bond line. Whatever edge is on the line that same edge will be on the line all the way up and down if you run on a 6 inch bond. If you run a 5 inch they will stagger and you will have to step it down to get it to come out right. The architect dimensional shingles are most forgiving.

[@natto_4]

​@@Lifes_Apprenticenail your tip row with a nail 1" from both sides of the shingle and add nails according to the new nail pattern. I'll often nail off the top of the shingle if I have guys potentially walking over the shingles. We just had a "journeyman installer" keyway 50+ shingles working out of a left handed book and being right handed

[@adamcombs2739]

1st u go with the lowest side not the lowest measurement to line up the other side. The lowest measurement would be the higher shingle. So That's wrong. There goes your margin of error plus 3/8. 2nd. After u determine your lowest side you get u a lin all the way across using the measurement from the lowest side (wich will be the higher number from the top) but u make the line = 5 & 1/2 from the number of the lowest side but do it on just each end to get 1 straight line all the way across so u cam have a straight line to measure off of and your top will come out the same across assuming it's straight so iff u had 164 and 163.5 u would go from top 158.5 from top and that'll straighten out your top. To get the bottom unsalted side you pull from your lowest line on top u just got all the way across to your highest bottom line and measure and find the first increment of 5.5 u cam hit wich should put your tape at a small angle. Do the same on other side to same measurement. If it doesn't reach scoot up another 5.5 higher now that you know wich increment will work best to perfectly hide any short shingles but dividing the distance out evenly. This also works for any step downs or to just straighten out top section so your top shingles are straight with the ridge. The reefer roofer. The higher I get the dryer you get

[@jeremypeardon41]

Not bad but my day shingles show 5 in to the weather You can start on the other side regular. Then when you get up about 12 courses to the top and start taking a loose shingle to a loose shingle and see how much you got to drop them That's how easy it is and the other side will meet up.

At 7:13 and up your seams are way too close. Looks like 3 inches it needs to be at least 6. Cut back the right side of your shingles if you have too.
