Wow you watched Larry Hain too. That man was a legend, knocking thousands of four in nails with a single lick of the hammer
My 11 year old boy is totally hooked on you Robin. He has now worked out how to use a speed square and has been waiting for this video. He has been asking if he can be your apprentice when his older. Can you reply and say hello to my son Franky. Cheers
Hi Guys, that's awesome that you want to be a carpenter Franky, well done for working out the speed square!! Its a great job being a carpenter and once you have a trade you will never go hungry and you can work anywhere in the world, I will give you a shout out in a future video what part of the country are you in maybe one day you could do some work experience with me? Have a great weekend
Hi Robin clevett I like watching you building the roofs I made a birds mouth in my dads shed we made. I used a speed square and a hand saw. I want to learn how to make your fence for your roofing square and pitch roofs when I’m older. I live in Gillingham Kent. Say hello to Roger buy from Franky.
Robin Clevett top bloke you are robin 👍👍
Absolutely brilliant you have to be the most technically proficient Carpenter I have ever seen in 40 years as a Carpenter on both sides of the World. My favourite Carpentry job like you was pitching roofs. Hardly pitched anything now for over 20 years as everything is trussed in Oz. I have pitched some complicated roofs back in the UK including Oasts, Eyebrows etc. For that skillion pitch in days gone by and never knowing how to use a roofing square. Didn't go to trade collage just indentured to old school chippies that didn't use one unless they needed a square. All I would use is a bevel a tape a block of wood and a piece of string. You know the height down from the window (fixed point) you know the back of the plate (fixed point) you know the size of your timber and thus the height the rafter will sit above the plate at the birdsmouth. Mark that height on a block of wood and pin to back of plate. Put a pin in the wall at the top of rafter under window and tie off a line between the two points. Use the bevel at the top to get the plumb cut and that gives you the seat cut. You can measure the length to the birdsmouth direct. As I was working mostly on centuries old houses we often measured each rafter individually anyway as the buildings were mostly out of level, out of square or both. I love watching your videos and your attention to detail and technical skill amazes me. Good luck with the app. I will definitely try it once it is up and running.
Hi Dave Your comment brought back a lot of old memory's for me, I worked with some old guy's like that but boy were they good every thing fitted like a glove , some times you have to fit to what's there and you need the old ways! I myself use the calculator now just a basic one and the roofing square. thanks for the memory's.
Those are the age old skills and ways, mock up your reference points and take it from there, no need for tape measures when you're sizing in place. One of the first things my grandpa (who was a stonemason) taught me about measuring were to use string for plotting, sticks for measuring, and blocks for spacing. He said: you may not always have a fancy toolbox to work with. If you know how to work from scratch, you will never get stuck, and tools will just make it easier. 40 years in I'm still learning.
@@disklamerThose old school Craftsmen were gifted, 👍💪💪🔨🇮🇪
I think an app is a great idea Roger, but still think people need to learn how to calculate these things first...otherwise we will be left with a generation of roofers totally reliant on an app...!! Lol...what if their batteries go down from taking all those calls whilst on the job...chaos...😳
It's Robin. Roger is the other one 😂😳
Ollie B...that’s what comes from watching the other one rabbit on about tubes full of gunk...!!
@@stun9771 hah I watched that too 😁
If you learn pythagoras theorem itll give you a good base line of how to calculate the length of the rafter from centre of ridge to outside of wallplate then you can do your deductions or add on at the ridge as robin has done in this case hope that helps 🔨
I think you have to know how the answer is arrived at but apps and calculators are a good thing but understand how it was arrived at otherwise if you hit the wrong button you won't know if you have the correct answer.
Hi Robin,
When you notch the top of the rafter over the pole plate, do you match up the depth of plumb cut with your plumb cut on the birds mouth at the wall plate E.g both 1/3 of the timber?
Many thanks!
Anybody else noticed Robins haircut? He can pass of now as one of his apprentices.
Really looking forward to this !
Also happy to finally have a master at work documenting the craft. A lot of brickies out their doing the same, the likes of Stu crompton but it’s great to see a British carpenter showing who’s boss awesome stuff 👁
This is a very satisfying watch not lightly to do this work myself but if I were Robin's skill level is where i would want to be he is real master of his craft. His videos should be shown in school's and colleges to showcase what a real skilled job is all about.
Robin should be nominated for the Nobel Prize for this app !!
Hi Robin, Thanks again for an informative video, as with all apps and the use of calculators to gain the lengths of roof sections it is based on every thing being perfect, could I say that with a lean to roof that you should always check the wall for plumb prior to calculating your roof as if you just measure from your plate level back to the wall if the wall at a higher level where your rafter will hit may be in or out of plumb, I have had some walls leaning by quite an amount and even bulges in the walls all have to be allowed for. This is a great time to be a chippy with all these gismos makes for an easier life but just proceed with caution this is from an old timer and still working. respect to you Robin and your dedication to this not always appreciated craft.
Nice tidy job Robbin.good luck with the app. And by the way I'm glad you finally got the hair cut. You look 40 not 50. Tee hee
I LOVE ENGLAND SO MUCH

How long until you release the roofing square Robin roughly, please? Looking forward to purchasing one 😃.
@saetyr 100% empire stair guages are the bes
Stair gauges are to small where dealing with rough sawn timber a large flat fence well clamped to the square is a much better option, I started my career back in the late 80's using stair gauges on the steel square but they where for ever falling off and even if there was a drop in temperature they used to fall also when marking a birdsmouth close to one end if using the stair gauges you sometimes fall off the timber with the gauge
The first prototypes are arriving with me shortly once these have been field tested and honed then I will get the filming of the tutorials done and the app finished and away we go!!!
Robin Clevett yeah, I agree with you there m8.
Great looking forward to your new square %tutorials
Nice job again, interesting though u don’t double trimmers on velux top and bottom . I thought this was regs. any opening above 600mm?? What your thoughts?
Is it because the distance between steel (and wall) and the window opening is less than 600? Not your standard velux those, their massive! Normally there'd be a greater distance from the steel beam.
As a roofer its pleasing to see the roof pitched and bird mouthed onto the wall plate, this would be a joy to cover in !
It would be great if you did a video where you could quickly go through the process of the lean to/monopitch roof as it seems like the place to start when learning. Thanks for the update 👍
I believe that's what the selling point of the app try pythagoras theorem itll help you out once you get your head around it 🔨
What's the app called?. By the way love your work. Incredible carpenter.
Hi Robin can’t find the answer so I’m watching all the bids again, did you produce your App and roofing square to the point of sale? Would like one.
Your right there Peter. The guy I mainly learnt from was born in the early 1920's and started as a Carpenter at like 14 years old. By the time I started working with him he was about 60 and was well known in my area as a roofing Chippie. If he couldn't pitch it then it probably wasn't possible. The modern ways are quicker and once you understand them no doubt easier but at least the old way taught you the principals and you could expand from there. In Oz most Carpenters can't pitch a roof they do a basic bit in college and then most never do another. Apprentices have shown me the book they get given on how to do it. No wonder they can't. Maths for the sake of Maths I didn't have a clue. I was taught there are only a few rules you need to know that are constant and you can pitch anything and from my experience that was always true. Robin is an exception in that he can work old school or new whereas I can only work old school but then I am ten years older than him.
Nice haircut Robin...👍🏻...
Nice music Robin, what's it called?
Great video but I have a question please regarding the wall plate and why the spars rise above the top of the wall plate?
I mean the back vertical wall plate attached beneath the windows
Nice sharp hair cut 💇♂️ robin 👍
Your a star Robin. Great video mate. Stay safe.
look forward to getting one of these roofing squares and the app... since lockdown mk1 ive went from guessing at roofs and faffing about with bevels and string lines and guessing... to having a fence for the rafter square i bought years ago and getting stuff to be massively more accurate and easier to do in a quicker manner. plus knowing itll work right from the start is amazing. makes me wanna do more and more roofs rather than worry about doing them
Did this ever come out? I could really use this right now!
Great video Robin
Never been in the building trade but love to watch, find it fascinating 👍
I'm a cut and pitch chippy myself used the stanley 10" quick square for years but will definitely purchase and try for myself...good luck Robin keep up the great work!
Why buy something if you already know what your doing
What was the projection of this extension Robin? I have a very similar rear of my property where I would need to work around a difficult double storey bay window. The roof tile for my property can go down to a minimum of 22.5 degrees with a 100mm headlap so I'm sort of governed by that which would dictate my projection. Unless you know of any work around from your previous jobs?
Chippy yoda
imagine being his apprentice it would be amazing
How are you getting a secure fixing onto the bay. I’m curious as don’t see any wall plate?
And me Dave. I saw your question and then watched the video. It appears the rafters are simply butted up against the bay with no wall plate.
@@frank1847 They are birdsmouthed over a pole plate on the wall, this is obscured by the camera angle, in the video I mark the top and bottom birdsmouths I think at one point of the video you can see it, hope that helps
Robin Clevett what’s the difference between a wall plate and a pole plate?
@@coops6621 A wallplate is usually on the top of the inside blockwork/steel lintel ,a pole plate is fixed to a wall where you have a lean to /mono pitch roof to bare onto. Hope this helps.
Mark Worthington ahhh thanks Mark. I’d heard the term but wasn’t sure. Someone told me it was the plate you sometimes have on top of joists
Thinking about trig solution ,inverse tan of ratio rise over run gives degrees .Deducting height over plate (2/3 of rafter size) from measured rise on wall first should give correct pitch in degrees.Run to wall divided by cosine of angle gives rafter length double check with Pythagoras takes under a minute on calculator Is this an over simple solution I very much take Peter Bell’s proceed with caution message.
Hi Robin, Just update you, your costing me money mate,I have only gone and updated my phone from gas to super smart so I can get your app when it arrives there's life in the old dog yet!! that block wall behind you another governing factor if it was already built at 22.5 . Roger better get you a neck scarf for Christmas with that hair cut!!!
I would think it would save a lot of time on ordering timber
What's the name of the app????
lean to roof?
Don’t take this the wrong way but I hope your square doesn’t make you a fortune,,, in case you retire as I enjoy your video as so much.
Soh cah toa is something every roofer should learn it's so handy. I'm a welder and an now starting learning the speed square and framing square.i always thought framing squares were pants but I think I could mark out stairs much faster
Hi, very educational Video, I thoroughly enjoyed it. What is the app called?
Hi Rob like the music 👍
Where's the app?
Where can I buy the app?
Where’s the app?
I have been a joiner for over 20 years and traditional roofs still challenge me. I am good at maths and hold a degree but because I don't do roofs often there always a pain, also most of the youtube vids are American, who are miles ahead of us at roofing so there quite complicated, also the swanson speed square book is all in feet and Inches. The books/ vids are fine until you come across an odd size building or something that's not quite square... I think I would give your method ago but most of the people that buy it probably won't be roofers and would use it irregularly so finding the right price point will probably be hard mate. Good look your vids are ace 👌
Where can I get the app?
Nice one Robin.
Top tip from me, when cutting the birds mouth cut along the grain first before cutting across the grain, that way the piece doesn't break out leaving you to clean up the 2mm edge where the circ didn't get to.
Is the app out now?
The Hikoki multi volt is a great saw
Powerful precise and light
A bit like Robin 😁
Wow robin, good work . Great cuts all round
Take it the app will also have some highly technical formulation on angles and lengths for users best haircut and mapping for closest approved barbers shop .
You look a new man, sure the wife pleased lol .
Slick
Robin,
Newly subscribed to your channel & loving everything about it. I'm very interested in your lean to construction & particular your method of setting out the build. I am currently removing an aged lean to & will be attaching it to an 82yr old existing double brick house with 4 X 2 hardwood wall plates & roof rafters. Would like to continue the lean to roof pitch to match the existing roof plane. Any tips on how to attach the roof rafters is appreciated.
Thank you
Troy
Heya Robin, love your work as always, quick question, what ACQ fixings do you use in your pressure treated timber? Stainless steel, ceramic coated or just a heavy coated hot dip galavanised?
its easy to see why channels like yours and @Stucrompton get popular. People like genuine guys who do a good job and know their stuff. what's not to like!
Hi Robin like watching your videos keep them coming all the best.
Top notch work Sir, can I ask why you didn't double up the headers on the opes for the Velux windows?
Hi robin any news on when your square will be available. Thanks
I wonder if customers realise exactly how high quality your work is or if they just think a builder is a builder so no different.
Hi Tony thats a really interesting point!!!! most customers just think about the costs!! and thats the only comparison they actually know!! I am pretty lucky that most of my work is from recommendation and the clients are looking for a proper job, that said I still need to be competitive!!!
@@ukconstruction strange and a bit sad isn’t it? When I hear people talk about tradesmen the three things I hear most is that they were quick, made no mess/cleaned up and were cheap. I never hear people say a lot about the quality of the work unless it’s about the decorating/tiling or finish. There could be a bundle of sh*t behind the ‘top coat’ held together with gaffer tape and staples but as long as the builder hoovered up before he left they’re happy as Larry 😂. My game (furniture making) is a lost cause because of the Ikea effect. Nothing wrong with Ikea at all but when you can buy a flat pack chest of drawers for 30 or 40 quid nobody really wants to pay 500 even though it will last a century as opposed to a couple of years before the drawers go squint and it goes to landfill. I sort of understand but I still think it’s become a funny old world. But what I can say is if you were based in Scotland you’d do every job on my house without a doubt regardless of price and if I ever win the lottery you’ll be my first port of call to build my new gaff 👍🏻. Top quality work Mister and I love watching your videos because of it. Good luck to you and I hope you continue to prosper 🍻
@@tonyalways7174 Thanks Tony, thats really kind mate, why don't you start a furniture making channel??
@@ukconstruction I’ve got a face for radio 😂👍🏻
please just put all the videos you're involved in here instead of doing stuff on a shopping channel thanks
😅 Harsh, Rogers a top bloke
Excellent as always Robin although you may want to get your money back for that haircut, always get 3 quotes.😂
Great Robin, Thanks for all your input and advice. Been a chippy for many years but still learning👍🏻
... the George Michael of Roofing ! :-)
Good video Robin. Nice to hear you are making progress with your roofing square👍
Great job mate..
But late for summer hair buddy? V smart😆
Any link to your app please Robin?
robin i would love to know how you laid out the plate and rafters around the bay window?
Good video would be interested in seeing the new app 👏🇮🇪🍀
Looking Forward to getting me hands on one of the squares when there out and the app sounds great. I Use a Gibson metric square at the moment. Really, in joy your videos 👍
Yeah it's the height over plate that gets me, I've got all the trigonometry dialed, run and pitch I can get the hypothenuse ÷ by cos° for example, but then getting the exact height of a pre existing ridge messes me up somehow... Still figuring it out!
Hi Tom This may help you, to get height times the run of the roof by the tangent of the angle plus rafter's height above plate gives height. Say for example 2.4m run times by the tangent of 40degrees = 2.0138 then plus upstand of rafter say .120 = 2.1338 ridge height.
hope that may help.
@@peterbell4154 thanks so much Peter!!
Hi Tom . Glad that it may help,another little tip that may help you can also use the tangent to get the length of a roof collar you divide the amount you want to come down by from the ridge by the tangent of the angle and that gives you half the length which you double plus the thickness of the ridge equals length of collar you obviously have to take into account if you have measured your height to the bottom or top of the collar. I do all my roof rafter lengths with the cosine. I'm an old carpenter still working and full of stuff like this I can bore people for hours😆
@@peterbell4154 B E A uitiful peter I'm glad someone else has can do the maths pythagoras theorem and tan all the available information is in the roof 👏👏👏👏👏👏👏👏👏👏👏👏 that and structural charts for roofing spans and integrity
Just a little more maths involved
Is the 1/3 rd principal of the seat cut the same on the wall plate bolted to the house ? Asking for a friend 🤣
Not really, I sometimes do half or even 1/3rd the other way!! So there is a longer plumb cut against the pole plate and I can use a fixing through the top directly into the corner of the pole plate, hope that helps mate!!
@@ukconstruction thank you 🙏
@@4fingerfrankie Be careful though, the deeper the notch the more short grain one will have in what remains. I wouldn't go anymore than a third.
Robin have you been pumping iron on lock down?
Thumbs down, terrible.
Hi Chuck, are you saying that a thumbs down to this video is bad?, it pretty normal even the essential craftsman gets thumbs down?? Its the nature of the beast you cant please everyone all the time! Have a good day
@@ukconstruction thumbs down to the whole damn thing. Everyone wants to be an expert, you can already download these apps to your smartphone. If not hire a fucking carpenter.
I’ve had an app to do this for over 10 years
Looking forward to download the app. Good work, great teacher.
Love your work and your videos.
Your app will be an unbelievable aid to us mere mortals.👍👍
Hope so!
Robin is the best Chippi in the UK
You are my new best mate Darren!!!!!!
@@ukconstruction haha I’ve been doing it twenty years and take it very seriously but your another level mate keep up the good work love the content.
Now I just need good help
The pole plate that you have fixed to the bay have you run that over as far as the double headers that form the window openings
well I like this to connect to the next full rafters the I also birdsmouth the ones that fall on the side of the bay over this too its a nice strong detail
Roof and ready reckoner book 🤔
Rodin cleverjig what a ledge
Look forward to your videos, always friendly and informative 🙂
Super nice job!!
That’s an elegant looking rafter foot on that pitch 👌🏻
If only all carpenters could take the time, love and care as Robin. 👌
Paul Marsh if only we were all paid enough to take the time!
There are plenty of good carpenters out their who can turn quality work out as good as robins
“Lean to roof” how far do you have to lean?
grate job robin
Would love to do a bit more of this kind of work havent done many roofs in my time.
Fantastic job Robin
Thanks for the update, i can not wait for it !!!
Do side cut of hip n hip jack rafter run on a 45 degree
Yes, but only if the wall plates meet at 90°.
👍
Do you need beta-testers?
Brilliant video

Thank you! Cheers!
Cracking job 👍
What's your opinion on the Hikoki battery saw thinking of getting one but few lads say the flexvolt better
Hi George, I have not tried the Dewalt, the Hikoki is a really nice tool, but like any saw it's all about the blade and the power of the battery, I will try a flex volt soon and then be able to give a verdict!!
George, depends what side you want the blade on too, and whether you want a rear handle or top handle...
@@dorsetengineeringHaving one of each is a real advantage, 👍💪🔨🇮🇪🇮🇪

Thank you Robin! Great stuff 😊
Thanks for watching!
First!
Will the app help with unequal pitches on hips i had one recently that was 43.2 degrees on the side and 35 on the hip end
I dont do lots of roofing but it was a real head scratcher.
Hi. These are called bastard or irregular hip end roofs. These were formed to give the impression/ illusion from the road that the ridge would seem in proportion to the property length thus hips not being 45 degrees to the plates.
Always done this with string lines, bevels and levels. They are never an easy one.
I purchase a book from America called “ The roofing bible. All imperial of course but a fountain of knowledge which you can translate to over in the uk. Some great illustrations if you are more visual to pictures/ diagrams.
@@chippytecarpenter4890 yes that’s the key, plate heights. Think of pivot points. Done a few of them now. Keeps your brain ticking. Enjoy them to be honest.
They are mainly used to create a longer ridge to give the impression the building is longer than it is, optical illusion I suppose.
Thanks for reply. Stay safe
