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.
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 ?
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?
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?
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.
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.
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.
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.
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
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.
Close valleys are one of the worst things to come over the border they go down just the the close cut pipeboot rage of the 90's what about that 3" stagger
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.
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 ?
No “Hey, great video.” No “thanks in advance for any input.” Just a demand for someone’s time, no niceties. Gotta love it…shocked you didn’t get a response.
Your videos have helped me so much! Thanks a ton! Fortunately I had a hipped roof but i was curious what doing a valley would look like. Seems like open valley is more diy friendly. Cut valley seemed a little less diy friendly but very doable. Woven seems like it would be easy to make it look messy for someone just learning this.
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!!
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!
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? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I1uzjqXc72c.htmlsi=xzv_ntkFBm3kUpUE
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
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 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.
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?
@@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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I1uzjqXc72c.htmlsi=xzv_ntkFBm3kUpUE
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 .
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.
