Let me know which of these 3 methods is your favorite to install!
Been waiting for this video!!! Thank you!!! :D
Open valley .....
ام كمال 😅😅😊😊@@EstateFlip
Such an awesome technique for installing that open valley, negating the need to cut shingles!
Glad it was helpful!
well back in the day, when mostly 3 tabs were used, I'm put metal in the valley and weave the valley. that it the best, other then that metal in the valley and closed is awesome too. Great Video btw!
It's great that you give these videos because some people just can't afford a new roof.some people can do it themselves with the use of these videos
That's me. My menopausal butt is going up the ladder.
Great comparison. Thank you. I like open valley with copper.
Copper Valley, thats nice!
Great video and will definitely help me with some roof modifications I need to do!
Right on!
That valley installation is amazing and confusing. I am planning on having a new roof installed. This give me information to work with and questions to ask. Great videos.
Glad it was helpful!
Great presentation. Very educational. Thank you
You're very welcome!
This video should have a lot of likes... nice exposure to the possibilities.
Thank you
Good work thanks for sharing this video I live around the corner from you guys
Thanks for watching!
Oui, merci Maître pour toutes les choses. Merci beaucoup.
Sorry, dont understand. But thank you for watching anyway
this was one of the finest videos I have ever seen... your details were clear and understandable and now I CAN'T WAIT TO DO MY ROOF... this helps me understand more clearly what the job is all about.... if I do the cut valley, do I use tin to line the valley before I put the paper, or after?
I've been roofing for well over 30 years been a good trade
Your work looks great
Thank you!
Hey this is a great video very well done I wish the valleys were longer but to do 3 types impressive. The cut valley wins for me.
Agree
Thank you , a great video, I subscribed right away. good luck
Thanks for the sub!
I agree with your analysis
Good Video
Thank you
Excelent information You Are Number # 1
Many many thanks
Great video bro at least the old 3 tabs are gone and people can more easily wrap there head around arcutectual shingles
Nice. We use the cut method
Good choice
Good video. I saw one video about a particular valley in which a woven pattern was used. The reason is that the valley didn't join two roofs perpendicular to each other but instead the roofs merged with about a 20-degree angle. The thought was that a cut valley in that case would fail.
A valley that doesn't leak would be the best valley.
100% the best Roof is the one that doesn’t leak. Aesthetics is secondary in roofing
I also like a space for water flow in valley and around skylights exc
I'm doing my own roof. I'm using the atlas storm master shake shingles. I live near Detroit michigan. I have a 4/12 pitch going in to a 2/12 pitch. What valley method would you recommend for this ?
Great vid.
Gotta say I like the woven valley. It looks like art. I sell it to customers as a mark of a roofer's signature skill. But that said, the cut valley does look crisp. Got no use for a metal valley.
All of them work. I think it’s opinion and what your used to. Thanks for watching and sharing your ideas
Quite a few manufactures spec sheets I have seen actually do not include woven as an approved option valley on architectural shingles. GAF specifically says not allowed. I know MALARKEY LEGACY, which is a thicker shingle, specifies that it does not allow woven.
As far a open valleys go, my roofing supplier has all the metal roof colors, which is somewhere in the 30’s, I think anything can be matched.
Ya, I dont think I've ever done a woven valley, but makes sence especially with thicker shingles.
OK merci
No problem
Awesome video. So the woven valley. Would that be the easiest way to do the valley? Also would you recommend putting roofing cement under the shingles in the woven valley?
Good question. I don’t think one is easier then the other. As far as mastic, it won’t hurt, but i always default to following manufacturer instructions
Don't weave architectural/composition shingles. You should only weave the bottom one or two at most. Most manufacturers will not approve the weave for installation practice
I've been putting down time lately not much shingles and was not planned that way just by luck
I am not a roofer in trade. When i replaced my parents roof about 6ish years ago in the valleies i ran ice and water shield, then a strip of 24" alum flashing, then i did a cut valley. I did this because growing up almost every year they had a different roofer come out to work on leaking in the valleies above an addition they had built. I dont know if its right, but it is not leaking.
If it’s not leaking it’s right.
Do we need to install any metal flashing going down the valley if we are doing the cut method? Or is it safe to do it over felt?
Just do it over felt, if you want to be safe out a roll of ice and water shield
6" step back from the starter strip
?
With a cut valley, how close, and how far, should the cut valley seam, be from the valley? I just had my roof redone two days ago. My cut valley seam, seems esthetically, too far from the valley. It looks like it works. It looks like if them seam was closer to the valley, it would look nicer.
I would look to see what the manufacturer recommends depending on the type of shingle installed. However I would say anywhere from directly center or a 1” offset. I think direct center looks nicer, however having it offset would allow for better water flow
What about a "cricket"? Can I use one of these methods, along with ice and snow shield?
Yes, though I prefer metal crickets, galvanized
I LIKE THE WOVEN VALLEY THE BEST. THEY SEEM TO WORK BEST WHEN THE OTHERS FAIL.
A differing opinion I like it. I can’t say it’s a wrong way of doing it
2nd method: did you trim each valley end of the course of shingles on the upper pitch? If you photographed straight down at the valley, we could get a better look!!
Yes
So my observation about the 1st method is dependent on how hard it rains I think water will seep up under the shingles that are laid over the valley flashing. I could be wrong but that’s my observation.
Don’t get me wrong now…great content I am not criticizing your content just the 1st method that’s my observation.
Same case could be made for a cut valley.
Do you have a company you can recommend in the Atlanta GA area?
No, you can check out directorii.com
At 2:16 you started to "install your first row of shingles." But then at 3:06 that shingle is gone. What happened? Did you mess up and you weren't supposed to put that first row of shingles down yet?
Correct, that was a mistake. Thanks for paying stock close attention
@@RoofRepairSpecialist Ah ok, Thanks for clarifying. Love your videos.
Is it better to start from shingling the valley first than outwards?
No, always better to start from a straight end. A gable or a wall
What about on a hip roof
If you're right handed, yes, start at the left and work your way towards the right, absolutely you can start shingling the valley first, makes no difference. You could run straight up the middle and shingle both ways if you wanted to, I wouldn't do that because I hate shingling right to left, but absolutely that can be done.
I'm not a fan of butting shingles end-to-end with no overlap and installing them perpendicular to the valley just to get a straight line. Sometimes called a California valley, and also used within other valley installation methods. Here in the north, water can get under the shingle, freeze, expand, and move or crack that shingle and the adjacent shingle. The object should always be to divert all water off the slope as quickly as possible, and not retain water or rely on the ice & water shield or the flashing.
35 years of roofing I've seen so much like running a kettle witch you must know I'm old know lol
Really like the explanation, but you can see the blow thru (?if correct) with the nail gun.
100% correct
Why wouldnt you flip the row that sits aligned with the flashing such that it is a solid piece instead of the tabs.
If I understand your question correctly, it’s so that shingle is exposed on the granular side
As a 35 year roofer there is only two types of valley I will ever install. My number 1 is w valley metal, and 2 is a cut valley. Weaved valleys are totally ugly, and a point out valley is a leak wating to happen.
Agreed
I used to enjoy the woven valley but shingle supplers won't warranty it anymore
Really, from what I know it’s still a approved method
So Tamko has a video showing starting on the larger roof/bigger slope, i put their valley install video link below. How much of a difference does it make starting on one roof or the other?

Big or small the concept is the same.
@@RoofRepairSpecialist Thanks for the reply👍
All new roofs are installed with woven valleys. Go to any new or even 10-20 year old neighborhood with original shingles and you will see woven valleys. Raleigh , NC. Area I personally don’t like open cut because that open cut edge will curl after 5 years. That shingle edge is relying on the adhesive and caulking to make that valley watertight. Here’s the easier way to understand it….take a water hose and spray directly on that edge of the open cut, then take it and spray it in a woven Valley… which one do you think is going to be more susceptible to water getting underneath the shingle? Obviously the open cut with the raw edge .
And yet they seem to work just fine. That is not a typical failure point.
This is SO wrong in several ways. You were lining up the right side of different courses of shingles (at 6:23+) ! A few butt seems of the shingles were practically on top of nails of the lower course ! WTH Bro ?
Those shingles were cut short just to make the demonstration easier to show.
Your shingle spacing is completely incorrect
I don’t think so
Why do they mispronounced center it is not on center it is called center
Center is center, I don’t think you are center
That’s 100 wrong
Your 101 wrong
2" offset..... you are fired i tear off all your work and redo it!
lol
smh
These videos can't be serious. I have sat here for the last hour and every one of these videos. These guys has called themselves out on their own videos of nailing wrong in the valley. What?
Now get off the crack pipe and watch again.
@@RoofRepairSpecialist I been watching videos lately to learn and most videos show the way you did it however shingle manufacture video below show starting on the other side of roof. How much of a difference will this make?
It's a super quick tampko video showing a closed valley.
czcams.com/video/I1uzjqXc72c/video.htmlsi=xzv_ntkFBm3kUpUE
He explains the rules of step back and then doesn't follow them. Not a very good example. Also you need paper going over the edge of the metal valley.
I’m pretty sure I do, I’m genuinely curios if not, can you call out the time in the video.
Pretty sure he means around 6:20 or so when you do not appear to leave a six inch setback. Looks almost like no setback.
Dry in goes under flashings always but I noticed the books were shrinking that can work if you know your nail placement come back and do your cuts
Sorry your job site/video is a mess
? What video
Open valleys are BS. You should never rely on the shingle adhesive nor should you nail in the flashing. The best valley remains the closed valley.
Is your concern on open valleys wind?
Don't follow anything this guy doing he has no clue what roofing is.
I would say you have no clue, but you do look like a wise old man.
@@RoofRepairSpecialist yup I started roofing before they had nail guns
So what's your suggestion? What do you think he's doing wrong? You can't make a comment like that on a short video like this and just not mention what the issue is.. otherwise you just look like a troll.
Agree with you. Fourty years roofer. Only use metal if roof too steep. Shingle over metal area lasts much shorter than field shingles and gets dirt under it real fast. For roof contractor is a good way to do it bc faster, but for homeowners not best especially as you see it here.
in England you dont nail all metal valleys along the sides to allow the
metal to expand and contract or it splits in a few years especially zink
