Absolutely loving this series. Massive thanks to roger for taking time to film and also to the boys for taking time out of their day to explain their work. Top notch.
The reason a hip is at a lower angle is because it has to travel further than the common rafters to get to the Same height. It travels further because the hip is along the diagonal of a square rather than a side (common rafter). You can visualise it easier if you look at a hipped roof on plan. The maths involves a a bit of trigonometry.
That's one massive ridge board! I wouldve assumed a single ridge with a board would be fine as the rafter are tied at ceiling level.
To me a much simpler way is a single ridge board with scarf joints and dragon ties for the hips, keep it traditional. Already have triangulation of the rafter so maybaswell use it.
Great video again by the way.
Came here to say that! And also that the '1.41' for a 45º pitch is from Pythagoras: The height (opposite) is equal to the horizontal distance (adjacent), so if they're both 1, the hypotenuse is √(1+1) = √2 = 1.41421356237 🤓
Ahh but why is the root mean square of a sine wave 0.707?? Exactly half....?? And 1horsepower is 0.707kw....... Its almost like the world is linked by a series of constant laws that govern triangles and waves (which is simplya constant line of triangles plotted on a visual reference, joined up by 1 line). Perhaps God drew it all with an isometric set square.... Who knows....
Hi mate. Quick question. Because of the ties and ceiling height and they have obviously been set out first. I assume that the position on the wall plate where the king commons go to take the hip are very important and the ceiling joists are set out from those marks so that the rafters and king commons are not fouled by the joist?
Thanks any help appreciated. 👍
First class tradesmen that all seem top fellas aswell, a month on the tools with these lads would gain you knowledge that’d last a lifetime. Good neat tidy job 👍🏽
Ive seen the guy who made the roofing tool on other videos. He's mustard! Really knows his stuff 👍👍👍👍
Great to see Daniel back on here. Hope to see more of him,very informative 👍
It took us a long time and some hard negotiations with his agent to get him back. He is such a star these days.
@@SkillBuilder 🙈
In this game every tool is a hammer. Except screwdrivers, which are chisels
And chisels, which are screwdrivers.
And for stirring paint! :)
Nice to see people who know what they what they are talking about.
😬. Thanks.
These guys are absolutely fantastic. Worth their weight in gold.
Excellent video 😉, love how you guys all get on & crack on 👍.
I feel your pain with the ridge, heavy & awkward. Looks an absolute treat.
Got to mention Dan's square - what an awesome bit of kit and beautifully made - couldn't work without mine now 😍😍.
Hope you can do more videos together as you make a great team.
Regards
Tim
Thanks Tim for your great support. 👊🏻.
It was great to film it with the chaps
🙏🏼
It looks like you lads are on a merry roundabout, making it up as you go along. Jolly well done.
I wish my wife was like a ForgeFast Screw... so reasonably priced and easy to get in!
Chippy and builders working through the downpour 👍 where’s the roofers? Hiding in the van😉😂
If they have any sense they are home in the dry
Love the vids with James in. Robin always said he’d challenge anyone to beat him pitch a roof, think that fella could give him a run for his money.
We aren't really into that "Who can piss the highest" mentality. More important is to get the job done and have a good day.
No race in pitching the roof. As long as we get the end result right. 👍🏻
Thanks
Some excellent carpentry work here guys, perfect birdmouths and angles.
I would have started with the gable end wall first with the beam pocket for the ridge beam and then installed the ridge beam, then the hip at the other end and then filled in the rafters.
Nice use of straight edges........I used them for checking all my custom roof framing.
Kinda wet, better than snow.
Thanks. The gable end wall wasn’t built as the gable ladders were built in once the roof was pitched. There’s a few ways of doing it, as long as you get the right end result.
Great job. For me, watching a roofer is like watching a magician. It totally baffles me. Amazing.
The hip or valley rafter is a more gentle angle because a hip or valley is always longer than the common rafter even on a 45° roof
Love watching James and Ian lol
Absolutely beautiful
Excellent video as always.. well done you
The reason the hip plumb and level bevels differ from common rafter plumb and level bevels is that the plan length of the hip rafter is longer than the plan length of the common rafter, so even though the rise is the same for the hip and common rafters the distance that each cover is different (the plan length of a standard hip is 1.414 times the plan length of a common rafter) the reason the angle differences for hip bevels is not consistent for all common rafter bevels is due to the 1.414 multiplier for the plan length of the hip. hope that helps
Square root of 2. It's not difficult is it!
One of the best vids for ages, should have been longer.
Was that a days work or over a couple of days.
It's a pleasure to watch true craftsmen at work. I can't see the snowflake generation turning out craftsmenship like that when they reach 40.
The whole job was a day and a half. Daniel has a really good apprentice right now so who knows what he will be like in a few years time.
We had good fun filming it, and I’m grateful to help James pitch it.
Thanks.
Lovely work guys. Loved the long detailed video!!
Dan has a great approach to his roofing, get on with it and it's done with out any faffing about.
nice one lads. The Cosine saves all that pencil work though Roger.
Thanks Peter. 👍🏻
Hi Peter
We will do that piece as a stand alone. When are we coming to see you?
That square is absolutely brilliant 👏
It is brilliant but Daniel was about to give up on it just before we met him. He has another 5 or 6 inventions which we would like to help him bring to a wider audience but it takes time.
Perfect job lads!
The good thing about strapping the wall plates down is that when a big wind takes the roof off it can take the top few courses of blockwork with it.
You are not wrong. I also fail to see what it achieves if the straps don't go right down to the floor joists.
Coming along nicely lads 👍
Thanks to James and Ian for inviting me over to pitch the roof, with a few laughs on the way. 😉
And Skill Builder for filming it. 🙏
All thanks to you mate, we had a great time and looking forward to the next one👍
@@jimichip Yeah with more tea.
It's really great to see a normal working man come up with a great tool for his industry and have the gumption to get it to market. Good on you mate. Cheers
@@SkillBuilder tea in bags!
@@jimichip Your roofer seems to like it loose and brewed in a pot, whereas you carpenters tend to go for Lapsang souchong with the leaves smoked over a pine wood fire of old rafters. Plumbers lay out the used tea bags on their dashboard and rotate them on a daily basis.
A double 9x2 ridge and hip..... that's nuts.
Perfect job
Thanks. 🙏
Ok say if you have 12inch square the diagonal corner to corner is 17inch I believe so that is why if you want to keep the pitch the same as the common rafter it alters slightly. So if you looking on plan and you looking at a hipped roof you would have 12 plus 12 to the king common. The hip would be 17 from ridge to plate and the jacks diminish according to spacing. Hope that makes sense. So if the common rises 6 inch’s it rises 6 over 12 inches of run and the hip would rise 6 inches over 17 inches of run. That’s why In most American books you’ll have 1/12 or 2/12 etc pitch.
It's lashing down :) love it.
another excellent video.
Dans the biz and the crew of course !!
Wow thanks. 👊🏻
That roof should be in the Tate gallery
Top work
'Ere, I had a brickie build my extension roof, I've had to have the roofers in twice... need to teach them to roof too!
What is that? a poor mans scarf-joint?!
Thanks for the laughs Rodger
Dislike. I wanted Rodger to say "Where's James?" Then see him pop up from behind somewhere...
It should have happened but we got a sidetracked by work.
@@SkillBuilder you let us down....
James was too busy admiring those reasonably-priced ForgeFast screws. They really do drive in beautifully. And so reasonably priced.
If you need to set your ceiling joist say a course lower as cant adjust you rafter as its running inline with an existing roof, can you infill between the cj's with another wallplate and birdsmouth the rafter over that, cheers 👍
Watching this video, working in the rain, reminds me why i convert basements for a living ☔
one day we will make it to Leeds and visit you.
I am sure the hip is a lower pitch as the rise is the same but the span is further
Yes that is explained in the video. The bit that we wanted explaining is why the difference is not a constant. It varies according to the degree.
Ah right have to find someone a lot smarter than me to explain that one 😂
angle on the hip plumb cut is different because the hip travels across along its run a longer distance but the height is the same so the angle is different the eg common rafter plumb cut is rise ÷ run 2nd function tan = pitch of common rafter 2.5m rise ÷ 2.5m = 1 (2nd fuction tan) = 45 degree now thats the same formula to get the hip the rise is obviously the same be ouse they meet at the ridge but the run of the hip is slightly longer maybe it would be 2.6m if do the formula to get the pitch for him it would be different and thats what the square takes into account when u move it to the hip 45 from the common 45
on the the old model dans chart gave you this new hip angle and you simply adjusted the newer version eliminates the need to have the chart the Stanley adjustable arm square works same principle Common rafter pitch 45 degrees line up with 12 on common rafter scale them when u do hip yiu move the arm to the 12 on hip valley scale this takes into account the longer distance the hip has to travel to reach the ridge
What talas said 🤷♂️😉😂😂😂
The SE was full of pep when they spec'd this extension. Hopefully they don't have any more surprises from here on in.
Think your engineer mate is pulling your leg 🦵
Hi, what is the adjustable angel tool called that was used to cut the rafters in correct angle with the skill saw? I’m from Sweden and have never seen it before. Looks extremely neat! .../Tom
Hi Tom, I used my roofing square to do some plumb cuts. It’s from Essential Carpenter Tools link in description.
Some cuts were done on a guide rail which the saw sits on. Thanks.
Tom
You can see it here www.essential-carpenter-tools.co.uk/
Looks like this video is going to cost me money for a new square
You won't regret it, even if you just hang it on your wall, people will think you are clever.
I wonder why the engineer wants such a large ridge beam. It is not holding any weight. The rafters hold themselves up and the joists hold them together.
My 1st hipped and valley roof is for rosemary valley tiles and hipped bonnets.
It's very stressful.
The plates aren't 100% square. I knocked them about as much as I could, but was hard measuring from corner to corner on my own. I got them parallel and within a about a quarter of on an inch.
The building was 3240 wide and 6455 long.
The plans are wrong, nothing works how it says it would.
I have to keep everything mono pitch to suit the tiles.
I took about 5x different readings from the original rafters which where all very slightly different.
All round 41 degrees.
I'm abit out of my depth for my first one.
I've only ever done lean tos, flat roofs and a few up and over gables.
I've done 3 hips, and one valley, I'm connecting to the original roof now and something has pushed it out so that one side is just under 48 and one side is just over 42..
Worrying like shit, am I fucked?
What a crackin iob
Thanks for all your great videos, please keep making them. What length are the screw fixings you have used for the roof rafters to the ridge ?
I've got a roof that needs doing just like the one in the video , can you recommend anyone near the Leicester area that can do this?
Where can you find a roofing chart
Plenty on line or go on my website and you can download it for free. 😉
Can't see any wall plate brackets.
Great job, good builders
Dan is your surname Pythagoras by any chance?
No... that’s my middle name.🙈
How long did this take you to do all the roof?
We got the main roof pitched in 2 days, however we did have a laugh and probably lost time as such.
James had all joists already in and he finished the roof off. ( fascia , soffits etc )
Double 9" x 2" ??? What is that engineer smoking!
Im doing a lean to, whats the equation to find out the exact height of a ridge board when you know your angle and level length from wall plate to face of ridge board ??
Where does he get the 1.414 ?
I only understood 1% of what that roofer was talking about
Honest question which roof square do you think is better out of this one and roffersqure
How can you work in the rain like that ? What about your power tools ?
We mainly use battery powered tools especially when it’s raining.
Guy plut shower tray above me strsight to timber joints. Is that legal because he leveled it on my plaster boards. I have 3x of those shower trays above me. Guy mafe 2 units with shower trays.
Any opportunities for Carpenters
Dragon ties to btm of hips?
It depends on what is required. If the drawing calls for it then it is done.
We will put a dragon tie in our next roofing video, it seems to be popular.
The collar ties are in compression not tension. And what's the fastener detail for the tie at the bottom of the triangle? For Canada it's some crazy number of nails that would Swiss cheese the wood if it's anything less than a 2x12 and usually the tie goes a bit further up on the rafters to reduce the requirement.
The reason why the angle of hip is less than the angle of the rafter is because you are essentially forming a square based pyramid at the corner of the building and the hip is running across this pyramid.
If the corner of the building where the hip is to be placed is square and the pitch angle is 45 degrees then the angle of the hip beam is expressed by:
hip angle = arctan ( tan( 45 ) / sqrt(2) )
hip angle = arctan ( 1 / sqrt(2) )
hip angle = 35.26 degrees
If anyone is interested I've done a step by step run down of how this is derived:
www.dropbox.com/s/wsi5yrrx3o5piwx/Find%20the%20Hip%20Pitch%20Angle.pdf?dl=0
(and yes I'm fun at parties)
Thanks Adam
The question I (Roger) was asking is why the difference between the hip and the rafters is not a constant? I am trying to work out if this is answered by your excellent drawing but it hurts my brain.
@@SkillBuilder Hi Roger,
I added some more pages to the PDF in that link above to try and explain (although I may suck at explaining it).
The long and short of it is that sin, cos and tan are related to the curvature of a circle and so any formula which uses them will not have a linear relationship. The angle of the hip is found using the tan function and so that's why it's not just a constant.
There's some "cool" videos on the unit circle that probably do a better job than I do explaining. 3blue1brown on youtube is particularly good with animations and such for stuff like this if you're interested.
Hope this helps and also wanted to say I'm loving the channel, learning a lot about practical building methods which is very useful for me :)
Why don’t we in this country do like other country’s and use pre made trusses....In think that structural engineer is getting paid by dulux paint to get give James some pain on his build...haven’t seen James custom made levels out much but guessing by the way he smashed that impact driver there probably in the bin 🔥🔫
People use prefabricated truss sections all the time in the UK. Traditional cut is becoming less common.
@@TurinTuramber must be where I’m based and working but haven’t seen any trusses used, only on new build sites and when mentioned to traditional roofers they don’t like the idea.
Ive watched all skill builders vids brilliant . Just one thing all the vids with clavet and others cutting hip rafters have a incorrect plane on hips .. They do not do the drop cut of seat cut ...check it out Roger plenty of utube vids on it ...you will be suprised .

How can you build a roof and not use a nail gun?
Roofs have been around longer than nail guns.
It was a pleasure working alongside these two. Their knowledge is plentiful. As for Daniels roofing square it is amazing! I’ll actually use it for pitching roofs rather than my speed square. It’s so simple to use and so quick. Well done on crafting such a tool!!
Thanks Ian, it was great fun filming it., even in the rain... 👍🏻
Great to see my 3 favourite builders/chippies working together
@@iangough7659 thanks 🙏🏼
Dan, what type of pencil do you use as I have not seen it before.
@@Ultimate-roofing-square. aaaa
If drills were not meant to be used as a hammer, why does it have a hammer setting?
Good point, it is just that Ian would prefer to see James using his own driver as a hammer.
Is James a fan of those reasonably priced ForgeFast screws or not? I know they drive in nice and fast, and they are reasonably priced, but I can’t work it out?
We think he likes them but he struggles to bang them in with the handle of Ian's impact driver.
@@SkillBuilder I’m going to get some ForgeFast screws if they really do drive in nicely.
@@mickyork41 and they are reasonably priced... apparently....
I picked up some about 3 years ago from toolstation as screwfix didn't have the gold screws I normally used in stock (I love the turbo golds, but they're just so expensive and it really adds up over a year), never bought anything else since. They're the perfect compromise between price, quality, longevity and ease of use. My only gripe is that getting one torx bit per box of 1200 40mm (or even 700 60mm) screws is too stingy! The bits last well (generally better than PZ2's due to less torque out), but not THAT well!
On my current project, every time I say to the Engineer "this is our issue, any chance we can do option B or C" he tells me in detail how to perform "option A". There's been a few swear words.
Brilliant video, You and James should be careful how you discuss constructing roofs, the structural engineer may be watching and thinking "I never thought of that " These guys are just covering their backs, We were told that the ridge was there just to hold the rafters in the correct place, ?do you have a ridge on a truss roof.
It certainly makes you wonder about structural engineers calculations..
The ridge and hips were much smaller timbers years ago, so my dad told me who I worked with most of my carpentry life. Thanks for watching.
Some of the structural design of this roof makes no sense to me, I'd guess the Engineer has designed everything as individual beams in bending to make their life easy, ignoring the more efficient truss action that is achieved from triangulation. In particular, if a roof is symmetrical and the rafter feet are tied, the ridge will see no bending. If the hip jacks are symetrical and their feet are tied, the hip rafter sees very little bending. Most older buildings often use very skinny timbers for these with no issue. Sadly, many Engineers don't seem able to get their head around the structural mechanics of traditional cut and pitch roofs, especially hips!
Can’t get their head round it or won’t? Easier to blindly over spec and cover their arses.
@@noskills9577 In defense of Engineers, the cheapest price often wins so there isn't always the time to do the more in depth analysis that will provide the more efficient solution we'd like to offer. I routinely lose work to cheaper Engineers that provided poorer service. I think informed clients understand that paying a bit more up front saves money down the line, but for residential work, most clients (homeowners) only do a few job a lifetime so any lessons learned from going cheap don't feed back into the next job. I think the notion of Engineers blindly overspeccing things is a bit of a catchall misconception that people use when wondering why that bloody steel beam is so big. You still have to do a calculation to know you're overspeccing, so by that point it's no more effort to spec something sensible - I'm more open to the idea that lack of knowledge/skill is the reason for poor design, rather than willful laziness.
@@smartbuildengineering is it common to do the roof structure in treated wood?

You guys are great. I’m building a house in Spain next year... I’ll give you a call. Will I get a cheaper job because you won’t have to work in the pi####g down rain.
Awesome workmanship! Great series 👍 makes you proud to be British 🤣
This is a great video made with clever humour and funny comments. These men are giving away their
years of invaluable accumulated knowledge, this will be of great value to young apprentice carpenters.
The reason that the hip does not sit at exactly 45 deg is because strictly speaking the 45 deg is only
on a level plane, the hip of course is falling and the angle of intersection changes slightly at any
given point.
Love the humour as well, British banter at it's best.
Roger's commentary is spot-on, as usual.
Thanks Kurt. Some of our viewers find it intrusive but I try to ask the questions I think will come up in the comments.
@@SkillBuilder Roger, I love your questions and comments because I am often asking those same questions as I'm watching. I really appreciate your expertise. I wish they didn't edit your comments from the "ask Skill Builder" segments. When Dillon tries to get smart, your comments provide a bit of comedy as well. Keep up the good work!
A well done cut roof. Gas nails can loosen ok, my own build I avoided the nailer guns went old school wire nails, heavy screws are good move.
I was able to draw my roof out on CAD helped the cutting schedule, a lot!
Brilliant video guys, loved it. Even though I'm not in the building trade I found it so interesting to learn about how to construct a roof, and the accuracy is amazing. I want one of those roofing squares for my workshop, not to use but to hang up to impress my mates that I've got one, well done!
What an absolute Pleasure to watch . The dream team pitching a beautiful roof . I should have been a joiner but I was told I was too clever 🤣🤣.
James just watch it back at 5 minutes but play Michael Jackson thriller over the top 🧟♂️😆.

I'd love to see a dream team of Roger, Robin Clevett, James, Ian and Dan all on a site together. It would be like the A Team, only with less jewellery, fewer cigars, and a more fuel efficient van...
I have a feeling it would get competitive.
A lot of toys would be thrown out of prams
Good the maths is well over my head right now
It's fascinating watching you guys do such beautiful workmanship with the materials and tools a sell everyday. I don't get to see the end product of what goes out my merchants front door so I love watching this channel.

Just ordered one of them roofing squares should make life easier!!!
Many thanks.
Great video this one, always had trouble with the hips, that 10 degree difference throws me every time. Why these structural engineers want big steel plates in them aswell these days I'll never know. 18 years in the trade and I'm still learning, cheers 👍🏽.
Beautiful bit of carpentry!!
Top job, love watching good roofing chippies, great marking tool
That was a great video, really enjoyed it.
We enjoyed doing it. Thanks
Maths teacher: Today we will be learning Pythagora's theorem.
Kid in back of class: Why sir? We'll never use it in real life.
2 years later kid on building site trying to work out rafter length: Now what did my maths teacher say about a right angled triangle?
I loved maths as a kid. Forgot most of it now though. With pythagoras it means something and you get the right answer.
Not sure about algebra though. 😬
@@Ultimate-roofing-square. I know what you mean. In school I had the highest mark in the borough for technical drawing, a trade probably defunct now with CAD. But a couple of years later i looked at an old school book of work Id done and had no clue how I could have drawn such amazing technical drawings. And algebra yes, bloody trains passing at ridiculous speeds all the time.
Great video guys. Informative and enjoyable. Thanks guys looking forward to next week's episode.
