HOW TO SHINGLE A CLOSED VALLEY

what's up everybody life's apprentice i've gotten a few requests um to do a video about how to do a closed valley and uh i just haven't gotten around to making it so today that's exactly what we're gonna be doing we got a valley right here coming up and a valley over there but i'm going to be showing you this valley right here this is as simple as the valley gets i'm going to show you how we do it all right so we're going to do a closed valley here we have our starter down which is a standard practice but what i always like to do is on the first course i always weave a shingle so this valley is going to go up underneath here first but our first shingle is going to go right here now another thing with valleys is your standard nail placement is not gonna apply so i'm gonna put a nail here i'm gonna make sure that this is down in the valley nice and flat and we're gonna nail that i'm just gonna cut this little bit of excess off we don't need that much now when you're doing a valley there's lots of ways to do it but i like to have and most manufacturers gonna recommend that you have 12 to 18 inches from the valley up so right here we have about 16 inches or so so we're going to use our normal pretty standard nail placement but we do not want to nail in the valley i'm going to put a nail there i'm going to put a nail there about a foot apart that gives me enough to give my six inch offset and then we're gonna nail this now this is not important where you nail it because this is all gonna end up covered up so we're gonna continue that you can put these nails over here they're not going to be seen oh so there you can kind of see how our offset is going to work we're going to continue that process all the way up to the peak so i'll show you when we're all done you can see we have our first course run through the valley now not every roof are you going to be able to do this offset without cutting especially on a steeper roof these are going to not be wide enough on this roof it's pretty much perfect so we don't have to cut them but you want to make sure that your offset stays about six inches so the other thing i didn't explain is when you're doing a valley there are certain reasons why you're going to go up one side and vice versa so this one here you can see this peak is diving into the main roof so in general i'm going to start on the smaller roof and i'm going to run the shingles up onto the bigger roof if you're doing a dormer which this is a little big to be a dormer but if you're doing a dormer where the peak is diving into the main roof you're almost always going to want to run this side up underneath this side like this sometimes if you have multiple pitches on a roof you're going to run whatever is the lowest pitch you're going to run your valley up underneath the steeper pitch not the opposite way so say this was like a 12 12 and this was a 412 we would never want to run the 12 12 up the 412 we would run the 412 up underneath the 12 12. so we have all these on and the next thing we're going to do is we're going to snap a line and we're going to start working on this side another thing when you get up to the peak here where this peak meets i just take a knife and i'm just going to cut that just like that you can see so we have our line snapped i don't know you guys can see that pretty well i hold it say here's the center of the valley i hold it like two to four inches on this side i don't want it directly in the valley i want it up just a little bit if you have a nice straight line running down there we'll show you what we do next so here's our next step we're going to run a shingle on our line and you're going to nail it on the tar line nail placement is not really that important on this as long as you're on that line that one i'll cut this excess off i'm gonna start running the shingles now when i'm doing this i'm running this corner right to here and we're just gonna nail the shingle you'll see how it works when we get the full ones again by doing it this way too you have a square shingle right here and when you nail this edge you're far enough out of this valley you never ever want to nail anywhere near the valley you want to stay at least eight inches away okay okay now that we're at full shingles we're just going to keep the normal nail placement and by doing this on this pitch in this situation our offset is pretty much perfect we don't need to do anything other than just keep working our way up oh oh here i'm starting to straighten myself out a little bit so i'm cheating these up just a tad because i can tell on my paper when i'm off a little bit nobody's gonna notice it down here but when you get up further they will oh yeah don't worry about it right now though so here we peeked our tar paper so i know that this tar paper is pretty straight to the peak so i have to adjust a little bit just slowly hmm let them watch me struggle okay so i'm gonna stop there because this next course is gonna run straight across on the other side of the roof so that's uh that's essentially it so you can see what it looks like going down and uh now we're just gonna continue shingling as normal all right well that's basically it it's pretty simple um the way that we do it i never do open valleys at least in our area i find that they leak and i just don't really like the way that they look in most cases i know in other parts of the country the open valley is very uh very popular but not around here you don't see it very often around here so there it is that's how you do that if you like that hit the thumbs up subscribe we'll see you on the next one
