@@Ultimate-roofing-square. Dan. Always a pleasure to watch your work. Make it look very easy. You mentioned all the degrees to rafter length factor chart could be found on your site. I’m struggling to find it? Thanks Jason
I am fascinated by these video's about Dan's roofing square. I sat at a desk with a computer keyboard for most of my working life. I was thinking that I would love to give that a go until it started to rain.
Just bought this tool and pitched my first L shaped roof. Absolutely brilliant tool, was invaluable. The engineering of the tool itself is also top notch! Thankyou to Daniel, Roger and skill builder for the videos which have helped this young novice make it happen.
Jason Great to hear! We love Daniel's square and we love Daniel because he is a joy to work with. He deserves his success with this tool. Some people buy it to do just one roof and it pays for itself in that one job but having done one roof it becomes strangely addictive. Maybe it needs to come with a warning.
I think its great seeing Dan use his square to help people. I bought one myself and it was a dream to use. I really like the fact you've got Dan and Robin to give different takes on how to do it as well. Two very skilled tradesmen with two different approaches.
Excellent stuff its almost like Google tube knows my thoughts and has put this video on my feed. Downloaded the pdf charts and bookmarked the roofing square. Well done for not building over surface cabling, hate to see roofers cut lead flashing around a cable which can be rerouted. Dan is my kind of tradesman, perfect balance of confidence and humility, and a clear communicator.
Skill Builder has come to be one of my favourite channels on UA-cam. And I don't mean in the genre of construction, I mean overall. In my past life, I was a 'wood butcher'-I chanced my way into shuttering/formwork carpentry back in 2000, and picked it up as I went along over the course of 15 years. I thought other aspects of carpentry was a mug's game, because back then I'd earn far more from shuttering, so I never bothered learning much of anything else. HOW WRONG I WAS. I got out of shuttering in part because of several people I knew losing their lives on site over the years, and got into I.T. instead. But after watching so many of these videos from Roger, Dan and Robin, I'd LOVE to get into 'proper' carpentry. They're inspiring teachers and effectively convey the steps as they're working-it would be an honour to work alongside them on a job. And I'm seriously weighing up my options as to whether I should reapply for my CSCS card, pull on a toolbelt and head back on site again-truly a testament to the value of these videos 👷🏽♂🔨🧰🔥💪🏽
Another great video. I've been thinking of ordering Dan's roofing square for a while. Perfect timing, I've got my own porch to do + one for a friend/customer. So will be placing my order this afternoon. Keep up the great work - it's great to tap in to the knowledge of quality trades people.
First , nice brickwork 🧱👌🏼 Second what a joy to watch Dan at work . Fantastic craftsmanship and a great tutor too . As for inventing that square, massive respect . I like his Roger asks all the right questions for us viewers watching . I’ve just watched build with A& E on an amazing roof then straight onto you two guys on this small but just as interesting watch roof . Lovely job as always 👌🏼😍😍🧱👍🏽. Rog makes his list . Right I’ll go and get this timber then ….. see you in 6 weeks 😳🤣
I like most of your videos. Always good for other trades to have an understanding of what the other trades do. This said.. As a Ahem.. Heating Engineer (Not a plumber). I'm happy for the roofing boys do their thing. Shiny new tools or not.
Hi Roger cracking job, awesome bit of kit Dan’s roofing square makes life so much easier, make a chippy of you yet Roger you smashed it all the best Tony 👍 have a awesome bank holiday weekend to you all 😀
I have only resent bought Dan square. It’s payed for its self with in the first two roof one being a traditional roof. It only took an hour from plate. Bare in mind my bricklayers before had were Bob on Best tool I’ve bought this year couldn’t fault it one bit. Much respect to you do you have made roofs a dodle
I've done a couple of roofs (including plates) and the clever bit isn't putting it on, but doing the calcs before one cut has been done. That hip option is pretty decent. Great video 👍
@@bikerchrisukk thanks. It has been fun and games but very happy with how it’s going now. Originally I wanted a bigger firm to sell it, but one thing and another I’m selling it. I have a great business partner who directed me in the right direction and I’m truly grateful to Skill Builder who gave me exposure, and fun filming.
@@bikerchrisukk 🙏. Getting the prototype made wasn’t as expensive, however when the first batch was made I did wonder if I’d still have them now.. Definitely right with the control. I get to chat to the customers, and built up a very nice community on various social media platforms. Had fantastic support from the customers, and a few offers globally to meet up from carpenters, last one was beers in Sydney Harbour.. 🙌🏻
Great job that. The reason the hip angle works on a framing square is because it is an imperial measurement given as a ratio rather than a given angle. So for example you will use a 4:12 pitch for the commons but 4:17 for the hips. The 17 should actually be 16.97inches which is the diagonal measurement across a 12"X12" square but is rounded up to 17 for simplicity. Providing the building is square this will always work out.
@@tk2097 You can do it all with the metric square but it requires some maths and scaling down to use it. That's why Dan's square is useful because it takes a lot of the hard work out of the job.
Don't let anyone tell you that, "You're going into a trade so you don't need maths", eh Rog? Setting out floors, tiles, fitting windows, building roofs, just calculating the most economic quantity order for the job, they all require a confidence with maths. And it's why we have maths in the first place; from Babylonian surveyors with their 3, 4, 5 through medieval masons trying to move or cut stonework the least number of times possible, canal navigators piling and moving earth only once and on through Victorian engineers to today's precision in everything, maths saves time, money, and mistakes. So if you want to be a master builder, pay attention at the back! :)
These videos are amazing Robin confused me when he was marking out the first rafter but once you see which cut is called what ie seat cut it all falls together I have no roofing project yet but I might make a garden tool cabinet with a small pitched roof just to try it out because it's so satisfying to watch never mind attempt! Fantastic videos chaps
Hi Stuart The more videos you watch the more it drops into place but there is nothing to beat having a go and a little garden shed is the ideal place to start. I can guarantee that you will love it.
@@SkillBuilder Skill builder videos and robins other channel are the only ones I watch if I want to do a job on the house already refitted all brand new door casings and fitting doors. I would love to see a video on what you would do with sagging cieling. Our house was reroofed just before we bought it and the company left all that shitty lime morter mixed in with old tatty loft insulation so that weight has been removed but the sagging remains unless you've done a video already?
Cheers Dan know a good few ways of pitching roof this by far is the easiest bought one of your squares the other day and has payed for itself and again first day getting it out on job 👍
Our structural engineer has specified double hip boards, how do you centre the hip in that situation and where do they sit in respect to the centre rafter on a truss. Also I assume it will be necessary to chamfer the board's as the hip is going to be 90mm wide and will kick the battens high in the air on centre. Dan's advice would be much appreciated.
@@SkillBuilder thanks for that Roger it clarifies what I thought would be the case. Ours is a complicated roof all cut on site trusses, half trusses etc. The double hips are 6.2 metres long,the pitch height above plate is 2.7m and we have raised ceiling joists that have to attach to the trusses. They've specified clips and birds mouth, all rafters are nail plated to the ceiling joists like trusses would be and all trusses nail plated together. I even had to design the concept because the engineer couldn't get the roofs to come together at the relevant angles joining the original roof. Work began yesterday but is going to be slow going.
Thank you for another great video, leaning so much from them. Just a question, when you marked the corner for the ridge length, did you have to allow for the thickness of the ridge plate?
As this was a lean to roof rather than a normal roof it’s slightly different as it’s a full ridge, where as it’s half the ridge on a normal roof. Hope this makes sense..
Hey Dan. How do you work out the pitch angle when working to a fixed ridge height? If you put a 6x2 upto the fixed ridge and on top of your wall plate and plumb your roofing square like you did, it won't actually be the correct angle because the rafter is going to drop at the bottom when you take the birds mouth out.
Hi Andrew, when it’s a fixed ridge I cut a plumb cut roughly to what I think it should be. Then project it above the ridge a third. So now it’s above the ridge and touching the corner of the wall plate. Now it’s sitting at the correct pitch. Hope this makes sense.. thanks for watching.
Your not singing in the rain your cutting in rain . When your dealing with a material like wood it’s never totally 100% predictable , but under the control of a master craftsman’s it can be tamed into submission . Best wishes and kind regards as always 😀👍👍👍
I doubt I’ll ever pitch a roof but I could watch Dan all day. True professional/tradesman/craftsman, seems so modest too. Roger’s not a bad bloke either 😀 Thanks for a great video.
Enjoyed the video chaps! I'm sure I've seen Roger doing a bit of roofing in past vids with Robin... Would have been more of a test of Dan's square to have a twit like me who's never set foot on a roof having a go at pitching! Looks like a useful bit of kit!
Yes you are right, I have done a bit before including loft conversions and pitched dormer but never a double hipped roof. We are always happy to take a complete novice and see what they can achieve. I think with Dan's square and a little guidance it would be a success.
Hi Paul, With trigonometry it’s 22 then the TAN button on a scientific calculator , then times it by half the span and this will give you the height. You will need to allow for ridge boards and height above plate on the rafter.
@20:21 I understand most of what's going on but could anyone explain how the bevel angle on the shoulder of a hip isn't the 45° bevel which the saw is set to ?
Hi Qualtiy kitchens. It is because it is a compound angle, The saw is cutting at 45 degrees but because you are also cutting at the angle of the plumb cut the real angle of the cut when measured with an angle finder or protractor is not quite 45 degrees. It would be in plan but not in 3D if that makes sense. Some experienced carpenters get this wrong. It is largely an academic point because you set the saw to 45 degrees and let God take care of the rest.
It is not uncommon to show the underside of a hip and plasterboard up to it on both sides but these days the 50mm of insulation which is now required on the underside of the rafters will cover it.
Yo, Dan Cox- you can adjust the cable length on the kapex saw. There's a cable clamp on the top of the fixed head. Two torx screws. Slack them a bit and just pull the cable through a bit. It really is perfect!
On figuring hips, if the plate is square and level the math is easy. If your pitch is 4/12, the hip is 4/17. If the pitch is 6/12 then the hip is 6/17. Test this out on a floor tile, if it is 12 inches long and 12 inches wide, the diagonal is 17 inches. Once you have the pitch, half is cut from each side of the hip. Then measure length at the seat cut but the birdsmouth cut might be deeper so mark height above plate then mark the seat cut. Also, the hip is angled 45 degrees so the sheathing only contacts the hip at the corner edges. Drop the peak of the hip so corner edges are on plane with the common rafters and nothing sticks up. There are several other rules that apply to hips and valleys, you must stick your tongue out the left side of your mouth while sawing from West to East in the Northern hemisphere. Opposite applies if you saw in the other direction. Never saw in a southern direction and if you're not sure always face north. Direction of cut has no bearing on the cut at all but you don't want a sunburn on your tongue. Once you have the roof on and youre in the shade it's fine and you can stick your tongue out all day. There are a lot of rules about rafter framing that vary by region. Probably why so many opt for trusses.
You are not thick. Watch some of Dan's other videos on this channel. It might take a few more viewings but you will get it and then it seems really simple.
Yes the hip is very slightly lower than the commons so the battens sail through on the corner. It is not that much of a problem on a tiled hip if the rise up a tiny bit and it is possible to notch the battens.
Roger - Here's a way to convince yourself that the common rafter angle/hip rafter angle relationship should not be not constant. Think about the difference at the extremes of 0° and 90°. If the common rafter angle were 0° (i.e. a flat roof), then the hip rafter angle would also be 0°. Likewise if the common rafter angle were 90° (i.e. the angle is so steep that it becomes a continuation of the wall), then the hip rafter angle would also be 90°. So at the extremes the difference is 0. But we know that in the middle there IS a difference (as you say, because the hip rafter travels a further distance along the base for the same height). That means that if you imagine the roof angle gradually increasing from 0°, the angle difference must at first also increase, but then at some point it must start decreasing again so that when the rafter angle reaches 90°, the difference comes back to 0. ********************************** EXTRA: I thought it might be interesting to include a formula you can plot on google (see below) to see this in action. The formula is quite easy to derive with a little trigonometry, but as it's most easily explained with a diagram I'll just state the result. (By the way, this is an "idealised" formula, designed to illustrate the basic geometrical relationship without taking into account details like thicknesses etc - as Richard points out below, for an actual build please consult published tables.) θ is the common rafter angle θₕ is the hip rafter angle L is the length of the common rafter *in plan view* Lₕ is the length of the hip rafter *in plan view* θ - θₕ = θ - tan⁻¹(L/Lₕ*tan(θ)) You can plot this by copying and pasting the following into Google: y = x-atan(0.8*tan(x*(2*pi/360)))/(2*pi/360) θ is on the x-axis, and θ-θₕ is on the y-axis. I've set L/Lₕ=0.8 here, but obviously you can set this to any value between 0 and 1, depending on the dimensions of the roof in question. You will see from the graph that θ-θₕ=0 at θ=0° and 90°. As for what happens in between, we might guess that the maximum difference happens at 45°. This is approximately true when c and h are close in value (i.e. when L/Lₕ is close to 1), but as Lₕ becomes significantly larger than L (i.e. when L/Lₕ is much less than 1), the maximum difference actually occurs at values greater than 45°.
I have new conservatory with warm roof. the roof is aluminium frame with OSB with vapour barrier on top with aluminium tiles and with 2 layers of silverback in insulation and insulted plasterboard. Will this rot?
@@Ultimate-roofing-square. cheers for that Dan I noticed how Rog pinched it off you in the vid )) By the way it's a real pleasure to watch a master at work no one is ever to old to learn 👍
Velcro strapping is a good thing to use for re-usablecable ties. If you sew it into a permanent loop around the loose end, then when you coil the cable it is handy just to wrap the velcro around the main loop bundle. :)
You are right, it was the rain that put us off but it is a great app and totally free, even if you don't buy the square but it would be nice to give Dan a quid in our tip jar. We will pass it on.

He's A Smart Cookie That Carpenter 👏👏
Your Not A Bad Apprentice Yourself Rodger 🤔😛👍
👍🏻. He’s great. 👊🏻
Your not singing in the rain your cutting in rain . When your dealing with a material like wood it’s never totally 100% predictable , but under the control of a master craftsman’s it can be tamed into submission . Best wishes and kind regards as always 😀👍👍👍
Brilliant 👍👏👏👏
Amazing tool
Thanks Dean. 🙏
Hi Rog. What mechanical carpenters pencil does Dan use? Can’t seem to find it on internet! Ta. 👍
It’s a pica, but the larger lead one. 👍🏻
What length nails do you tend to use in your nail gun for the rafters guys?
Looks great
90mm
I doubt I’ll ever pitch a roof but I could watch Dan all day. True professional/tradesman/craftsman, seems so modest too. Roger’s not a bad bloke either 😀 Thanks for a great video.
Thanks Iain. 🙏
Enjoyed the video chaps! I'm sure I've seen Roger doing a bit of roofing in past vids with Robin... Would have been more of a test of Dan's square to have a twit like me who's never set foot on a roof having a go at pitching! Looks like a useful bit of kit!
Yes you are right, I have done a bit before including loft conversions and pitched dormer but never a double hipped roof. We are always happy to take a complete novice and see what they can achieve. I think with Dan's square and a little guidance it would be a success.
@@SkillBuilder And I would be well up for that! Always good to add to your skillset. 😉
@@burwoodbuild glad you like the video, thanks.
Where can we buy the square?

can you tell me how to get ridge board height ie the rise on a 22 degree pitch gable end
Hi Paul,
With trigonometry it’s 22 then the TAN button on a scientific calculator , then times it by half the span and this will give you the height. You will need to allow for ridge boards and height above plate on the rafter.
love the video, good learning.. but... can u guys show us how to do this without this squarre from Dan? Just so we know how to do it tradionel?
2 sliding bevels and alot of head scratching lol
Dan Cox is like Bro I wanna go home
@20:21 I understand most of what's going on but could anyone explain how the bevel angle on the shoulder of a hip isn't the 45° bevel which the saw is set to ?
Hi Qualtiy kitchens. It is because it is a compound angle, The saw is cutting at 45 degrees but because you are also cutting at the angle of the plumb cut the real angle of the cut when measured with an angle finder or protractor is not quite 45 degrees. It would be in plan but not in 3D if that makes sense. Some experienced carpenters get this wrong. It is largely an academic point because you set the saw to 45 degrees and let God take care of the rest.
What’s happens inside when the hip rafter is lower then the common rafters and jacks? How do you plasterboard it? Won’t the hip be to low? Thanks jase
It is not uncommon to show the underside of a hip and plasterboard up to it on both sides but these days the 50mm of insulation which is now required on the underside of the rafters will cover it.
Yo, Dan Cox- you can adjust the cable length on the kapex saw. There's a cable clamp on the top of the fixed head. Two torx screws. Slack them a bit and just pull the cable through a bit. It really is perfect!
Thanks, I cut off about 8 inches, so it was a bit much to pull back, however it’s a good tip. 👍🏻
brilliant vid SB
On figuring hips, if the plate is square and level the math is easy. If your pitch is 4/12, the hip is 4/17. If the pitch is 6/12 then the hip is 6/17. Test this out on a floor tile, if it is 12 inches long and 12 inches wide, the diagonal is 17 inches. Once you have the pitch, half is cut from each side of the hip. Then measure length at the seat cut but the birdsmouth cut might be deeper so mark height above plate then mark the seat cut. Also, the hip is angled 45 degrees so the sheathing only contacts the hip at the corner edges. Drop the peak of the hip so corner edges are on plane with the common rafters and nothing sticks up. There are several other rules that apply to hips and valleys, you must stick your tongue out the left side of your mouth while sawing from West to East in the Northern hemisphere. Opposite applies if you saw in the other direction. Never saw in a southern direction and if you're not sure always face north. Direction of cut has no bearing on the cut at all but you don't want a sunburn on your tongue. Once you have the roof on and youre in the shade it's fine and you can stick your tongue out all day. There are a lot of rules about rafter framing that vary by region. Probably why so many opt for trusses.
I must be thick because you totally lost me but a great video and an excellent tool.🤪
You are not thick. Watch some of Dan's other videos on this channel. It might take a few more viewings but you will get it and then it seems really simple.
Every time I watch those roof pitching videos my brain blows up
If you spent a day with Dan you would find it is not such as puzzle.
Did you drop the hip to compensate for diahedral angle ?? I think roger made mention of it earlier in the video but nothing about it afterwards ??
Yes the hip is very slightly lower than the commons so the battens sail through on the corner. It is not that much of a problem on a tiled hip if the rise up a tiny bit and it is possible to notch the battens.
@@SkillBuilder cheers Rog !! you should do a video of the hip drop calculation or diahedral backing one of these days 👍
Roger - Here's a way to convince yourself that the common rafter angle/hip rafter angle relationship should not be not constant.
Think about the difference at the extremes of 0° and 90°. If the common rafter angle were 0° (i.e. a flat roof), then the hip rafter angle would also be 0°. Likewise if the common rafter angle were 90° (i.e. the angle is so steep that it becomes a continuation of the wall), then the hip rafter angle would also be 90°. So at the extremes the difference is 0. But we know that in the middle there IS a difference (as you say, because the hip rafter travels a further distance along the base for the same height). That means that if you imagine the roof angle gradually increasing from 0°, the angle difference must at first also increase, but then at some point it must start decreasing again so that when the rafter angle reaches 90°, the difference comes back to 0.
**********************************
EXTRA:
I thought it might be interesting to include a formula you can plot on google (see below) to see this in action. The formula is quite easy to derive with a little trigonometry, but as it's most easily explained with a diagram I'll just state the result. (By the way, this is an "idealised" formula, designed to illustrate the basic geometrical relationship without taking into account details like thicknesses etc - as Richard points out below, for an actual build please consult published tables.)
θ is the common rafter angle
θₕ is the hip rafter angle
L is the length of the common rafter *in plan view*
Lₕ is the length of the hip rafter *in plan view*
θ - θₕ = θ - tan⁻¹(L/Lₕ*tan(θ))
You can plot this by copying and pasting the following into Google:
y = x-atan(0.8*tan(x*(2*pi/360)))/(2*pi/360)
θ is on the x-axis, and θ-θₕ is on the y-axis. I've set L/Lₕ=0.8 here, but obviously you can set this to any value between 0 and 1, depending on the dimensions of the roof in question. You will see from the graph that θ-θₕ=0 at θ=0° and 90°. As for what happens in between, we might guess that the maximum difference happens at 45°. This is approximately true when c and h are close in value (i.e. when L/Lₕ is close to 1), but as Lₕ becomes significantly larger than L (i.e. when L/Lₕ is much less than 1), the maximum difference actually occurs at values greater than 45°.
Good chat mate,, if only I had the concentration to read it 👍🏻
Nathan
That is brilliant, I don't know why but it makes me a lot happier doing a job when I understand what is going on.
@@SkillBuilder Absolutely!
I have new conservatory with warm roof. the roof is aluminium frame with OSB with vapour barrier on top with aluminium tiles and with 2 layers of silverback in insulation and insulted plasterboard. Will this rot?
Can’t beat a skilful joiner 👌🏼
Rog where's that pencil from I need a few of them !
The big one is a pica. It’s very good, square lead in it.
@@Ultimate-roofing-square. cheers for that Dan I noticed how Rog pinched it off you in the vid )) By the way it's a real pleasure to watch a master at work no one is ever to old to learn 👍
@@jharris7407 oh yes, I was his pencil and tape assistant..
many thanks, much appreciated. 🙏
Are you planning on making a smaller version of the URS like a speed square? It seems a rather bulky tool.
You don't put it in your pouch so why does it have to be smaller?
@@SkillBuilder So it's a tool to be left by the mitre saw? What if someone comes along and pinches it?
Velcro strapping is a good thing to use for re-usablecable ties. If you sew it into a permanent loop around the loose end, then when you coil the cable it is handy just to wrap the velcro around the main loop bundle. :)
i love that square, i'm a shopfitter and never do any roofing but i still want to buy one, weird :)
What pencil is that?
It’s a pica, but the larger one.
Where can I get the square from
Link in the bio. ⬆️. Thanks
Dan, if I have an idea for a new product, how do I go about marketing it?
I’m no roofer, but that was Technically beautiful come the end, All about the angle of the Dangle !
Hi Dan that lads coming along well now ,what do you think?
Not too bad Peter.. 🙈.
Thanks for watching.
excellent
Were do I buy one of those squares please

Thanks
Dan should have taken the opportunity to use his App mate...It's as simple as you can get for anyone reading this...
You are right, it was the rain that put us off but it is a great app and totally free, even if you don't buy the square but it would be nice to give Dan a quid in our tip jar. We will pass it on.
@@SkillBuilder I'm sure if you had a link to a recognized charity many would drop a few pounds in here and there.
No need to plane the hip I suppose the. Battens will pick the tile course ?
Well, that settled that one. But can can doubler hipped roofer plumb a pitch. That is the next question needing an answer.
