Ordered my copy of Roof Framers Bible today
Great! Thanks for watching.
It's been great to have it book to look at as I'm watching the video..keep them coming
send me a copy
One of the best videos I have ever seen to describe a hip roof construction, excellent explanation!
Thanks. Our goal is to make the explanation clear. If I fail to do so please let me know! Thanks for watching.
Extremely clear demonstration outlining the appropriate setting out and cutting of timbers for a regular hipped roof. The close up shots of the junction between the common rafters, the hip rafter and the ridge board to demonstrate how the seat cut for the hip rafter could be dropped and the top edges of the hip rafter chamfered, was really helpful. Likewise, the explanation on producing appropriate Jack rafter lengths was most useful ( again related to the geometry in the vicinity of the ridge board, the hip rafter and common rafter). Thanks for providing this content - it simplifies many concepts for those of us wishing to learn about roof construction.
Thanks for watching!
Roof cutting is a dying art. Glad to see these videos on youtube.
Thanks for watching!
You tube is the only one keeping us together.
I’m glad you came along and that I found you.Thx for sharing your tips and tricks, and to clarify on how to use the roof bible.Your a legend ,Thankyou.
Glad it was helpful!
Thanks Barry for a great video! Just a note for viewers, as the model didn't show this: don't forget that rafters need to be tied with ceiling joists to be structurally sound.
You are correct. If the ridge isn't directly supported, then a solid ceiling joist tie across the building is required. Thanks for watching!
Excited for future videos! Have you seen the method of not dropping the hip and clipping the corner of the top plate at 45 this planes the HAP line with the commons and lines everything up perfectly as well. Would love for you to show the explanation as you did a great job showing the jack dedudctions
I have not used that method. I can see where that would work, but it would seem to be the "long way home". Thanks for watching.
Another great video, Barry! I wish I had these resources 20 years earlier when I was framing... always had to leave the rafters to the older guys. Keep these coming!
Hey Thomas. I'm glad these are helpful, but remember the main question is not how to do things right, but rather finding the right things to do.Thanks for watching!
Yeah .. Wish I had these resources years ago as well . Seemingly the old guys kept it secret and all to themselves and worked ya like a mule carrying plywood and floor joist all day .. LOL..
oh, that's how it's done, great stuff. looking forward to more framing tips.
More to come!
Absolutely brilliant. Thank you. Marta Jersey UK
Thanks for watching!
Very good 4 hip rafters & the jack rafters! I’ll buy your book!
Excellent! Thanks for watching!
GREATLY APPRECIATE YA TAKING THE TIME. Excellent Video!
Thanks for watching!
The best video I have watched on framing. Keep the videos coming. Thanks
Thanks for watching!
This channel is awesome.
I appreciate that!
It's really great. It helped me study a lot. Thank you👍
I'm glad it helped. Thanks for watching!
Really helpful for turning an old electrician into d i y carpenter. Thanks.
Glad to be of help. Thanks for watching!
Awesome!
Very clear
Thanks for watching!
Nice info... since you wrote the book, I'm hoping you will go into more detail about the rafter tables and more rafter mock-ups... Thanks
Thanks Aaron. Did you see our first video on basic gable roofs? It covers the details of cutting common rafters. We will be posting more videos soon. Next up are two videos on irregular, or bastard hip roofs (parts 1 and 2). These will show how Roof Framer's Bible is used to get all the detailed info needed for these complex roofs. The rafter tables and related info are fully explained.
@@RoofFramersBible Yes, I did see the other video and will go back in and like... I'm glad your going to continue with this series, I believe that the rafter tables and the square are two of the most overlooked when roofing is being explained. So please don't leave any stones un-turned.
Very good 📐🫡

Hi, brilliant book, just brilliant. Can i ask in regards to a standard (pitch same on all sides) hip roof, is it advisable to always drop the hip lower than the HAP of the common rafters as illustrated in the book?
And in regards to irregular or bastard hip roofs you don't do that?
Yes, you would typically drop the hip to avoid having to "back" the hip. For a bastard hip, if the pitch difference isn't too great you could cheat a little and just drop the hip an average of the two hip drops. But if you want to be completely accurate then you would need to back each side of the bastard hip rafter. Thanks for watching!
Great video, question I'm trying to make a hip roof for a shed the dimensions are 24'x24' what would my ridge be? 24 Length - 24 Deep=0 plus the thickness of the ridge 1 1/2. So my ridge would be 1 1/2. Thanks
If it is a regular hip roof, then you are correct - 1 1/2". It's kind of hard to call that a ridge isn't it? Good luck, and thanks for watching.
Instead of using 1 1/2 as ridge the two first rafter should be full length without deduction the other two deduct 3/4 from both
Everything I’ve done with string lines and the Phonics method of building is clearly explained. This is so great!!
I'm glad it was helpful. Thanks for watching!
@@RoofFramersBible the salient point for me is how, and where to generate measurements. Understanding the geometry, ratios of angles, and knowing when to add/subtract material thickness has been super helpful!
Really all of the angular math in building any structure (that has squares and triangles) boils down to chugging out ratios!
You are exactly right! Once you understand the principles you can build anything. Just take it piece by piece and solve for that next triangle. Thanks for watching!
This whole time, I thought you were saying from the o-ring, and I'm over here trying to figure out what the heck you're talking about... halfway through, I hear overHANG, lmao.
Ha! I can sympathize. I don't hear half of what my wife says. Thanks for watching!
When you said you should use the length of rafter to tail instead of HAP … how do you figure out the total length of the hip rafter considering the overhang is different on a hip? How did you know how much length to add on?
You can use several methods. You can physically lay it out with the framing square, or you can calculate the hip length. In our example since we were using an easy 12" overhang on the common, then the hip tail run was 17" which we laid out with the framing square. Or, you can use Roof Framer's Bible to get either the tail length or get the entire length of the hip. You could also use the tables on the framing square. Thanks for watching!
How do start assembling the ridge beam? How high from the ground?
Usually you would just set common rafters on the sides and end of the ridge. That will set the ridge height. You would then just strut under the ridge down to a wall to support it. Of course you could also calculate the ridge height. Simply take the adjusted run of the common rafter and use that to calculate the rise. Then you add the H.A.P. (height above plate) of the common rafter. That will give you the height to the top of the ridge. If some of that isn't clear to you, watch this video. ruclips.net/video/mjBEeN-O_Oc/видео.html
What do you do if the short hip king common rafter is not on 16 in on center? The long hip you mentioned and have shown. But on the short hip if you want to go 16" on center, then one side will not match on the 45 degree hip.
I'm not 100% understanding your question, but if rafters are off layout for any reason it is easy to adjust the jack rafter lengths. Roof Framer's Bible for each pitch gives a figure of "jack rafter length per inch of layout", that is used to quickly make those adjustments. Thanks for watching!
Do you offer in person classes? Where?
No classes here. Nick Ridge does that though. He is in California. He is on Instagram as "roofstacker". Thanks for watching!
@@RoofFramersBible thanks for replying!
If you had to do a hip drop and amend the H.A.P, would it technically change the pitch of the hip?
No, the pitch of the hip would not change. The entire hip would drop straight down and remain the same pitch. The H.A.P. also would not change from the common. It would just be measured at the edges of the hip instead of at the center of the hip. Thanks for watching!
@@RoofFramersBible That makes sense. Thank you.
The illustration first shown at about 1:10 min. appears to have an issue. The left end hip has 3 jack rafters on one side of the king common while the other side has 4 jack rafters!
You have a very sharp eye! I actually had never noticed that. That is an isometric drawing to illustrate it in 3D. It was drawn for perspective and is not a scale drawing. You are correct. Thanks for watching!
Una pregunta en este tipo se techos como se busca la altura del caballete con esas medidas de este ejemplo de este te ho del video
Para obtener la altura de la cumbrera, debe agregar la altura sobre la placa (H.A.P.) a la altura de la viga común. Lo lamento. No hablo español, así que estoy usando una aplicación de traducción. Espero que responda a tu pregunta.

Gracias amigo por tu atención 👍
Tus videos son de mucha ayuda para my
I don't mind using common length difference for hip jacks rafter on small spans . I will not use CLD on a large home with a 48' hip... Even the least minor deviation " In the perfect world of framing " can lead to customizing every sheet .. If I do a hip to heel sweep measurement and transfer the HAP or as I call The Heel Plumb Cut Line . Then find the second to the shortest with a heel sweep off the lead rafter . Then transfer the HPCL .. subtract the shortest from the longest and divide by what the book says is the CLD as a constant . I generally find a real world error and refine it . If a book says the constant is 19.22 but my calculations come out to 19.27 according to what's exist in the field . Those .05 " add up quick per rafter. So then I'll input a new constant and begin deducting from the longest and it will return to the second shortest and further deductions will find the shortest with supreme accuracy . I can use every descending 4th hip jack rafter as a hip stabilizing brace and fill in the blanks without layout and achieve deadly precision in an imprecise world . This method keeps every one humming along .. I also teach my guys to write numbers like 18'-3-3/8" as 219-6 .. Another thing that can cause a headache if the HPCL at he hip . How many times have we all seen a hip not being lowered at it's specific height and many wonder why it whiplashes up like a pagoda. Also . I like to draft a visual pyramid for a a bastard hip/ valley , Calculate all angles , cheek cuts , inclinations, plate settings and have all the trig ratios. I call it a Rosetta Stone where I can see what has to happen and have it hanging near my blueprint table .. When dealing with some insane roofs with 20 uncommon pitches all colliding .Better have your brain on high alert .
I agree with the "better have your brain on high alert" comment! Framing a complex roof isn't for the faint of heart. Certainly there will be site errors that can throw off the calculated lengths, however I have found that if the foundation is level, square, and true dimension it is amazing how well the calculated lengths will fit. As the old saying goes, "math doesn't lie". But at the end of the day the carpenter has to work with what he is given and make it work. My hat is off to all the hard working carpenters out there busting a gut everyday to deliver quality. It isn't easy. I know because I've been there. Best wishes, and thanks for watching!
Very informative but your makita sounds tired
Yep, me and that old saw have some miles on us! Thanks for watching.
Cant get the bible delivered from amazon to Ireland
We have sold them to Ireland before. I don't know if Amazon has had a change of policy with regards to Ireland. Unfortunately we do not offer international orders except through Amazon. I will look into it. Thanks for watching!
It's OK, my good lady wife has just informed me that she has managed to order it. I don't know how she did it but she did. Looking forward to reading the bible
Good deal! Thanks.
Here is how I get the length of the hip and the first jack My book gives the length by the span of the building say it is 24 ' so I deduct the with of the ridge so I would look up 23' 10 1/2 '' and that would be the length of the common. but under hip and valley I would look up the same length and that would give the exact length of the hip or valley no shorting. to get the length of the first jack. I take a cut common and let the tape hang over 7/8'' inch because the exact length of the common to the center of the ridge is about 7/8'' longer than the cut length.. then I take 1/2 the diagonal of 7/8'' and that is 1 1/4 let the tape hang over 7/8'' and subtract 3/4'' from 1'' and a quater that is 1/2'' then deduct the differrence in length
That works! There is more than one way to skin the cat. Thanks for watching!
I give simple mathematics
Sir how old do you sorry 😂😂
Ha! Old enough to have built thousands of homes. Good luck and thanks for watching!
Personally I like gables more. Less a job to roof and cheaper for joists, roof sheeting and roofing material. Get your run of starters cut to start and your done in half the time! Sorry to disappoint you!
Yep, gables have their advantages. Hips do as well. For instance you don't have to buy or install the siding in the gable ends. They both are just tools in the architects toolbox. Thanks for watching!
@@RoofFramersBible Fun fact: Shed roofs, gable roofs and hip roofs have the same surface area when they have the same size, same pitch and same overhangs.
