Loving the big build series Robin. As a 59 year old joiner I think it’s great to see you showing and educating Dan and Oli the construction method of a traditional roof. Keep the videos coming 🛠🛠🛠

[@carlroge]

brilliant as per

[@ukconstruction]

Hi Carl, good to meet you!! Love your work man!!!

[@johncoppock3823]

Top job. Great to see the lads grinning in that. They can do that with pride knowing the fantastic project they are creating with you.

[@royordway9157]

I'm doing a job right now that is a simple shed roof over a roof-top deck at a pub. I'm an old guy who usually works alone, but for this job I have some young muscle coming to help put it all together. Everything is precut, posts, beams and rafters. I laid out everything on the ground so on Tuesday morning when the guys show up, we can just insert tab "A" into slot "B",,,,,,,,I hope. We have a 70-pound load rating for a roof here in Maine so its 2x10 rafters 16" OC sitting on triple 2x10 beams and it's all heavy.

Just up, cup of Tea, sitting here on the the Kitchen floor avidly watching another great episode while my 12 Week Boxer Puppy 'Ernie' is curled up asleep in my lap! Best way to start any day Can't wait for the next episode. Be safe! ✊🐾🇬🇧 Thanks Robin.

Robin, you have my greatest respect. You are making building things cool.

[@ukconstruction]

Thank you so much 😀

[@chrisgardner2597]

Looking fantastic lads

[@wrightwoodwork]

Brilliant working methods. My attitude is the more you do on ground level the safer it is.

[@3house325]

Those scarf joints look flawless. I noticed them earlier in your videos, honestly these parts are a joy to put together.

[@ukconstruction]

Glad you like them!

[@royordway9157]

I have worked on many old houses from the 1800s and have never seen a scarf joint in them. I have however, seen them in old post and beam barns and wooden ships.

[@gazobee]

This whole series is blowing my mind. I almost feel that I could use this to self build. The benefits of you sharing your knowledge are immense. Thank you so much. With regard to self building, I would actually leave it to the professionals. 👍🏾

[@ukconstruction]

Glad you enjoy it!

class stuff as usual. efficiency at its best

[@jonny4288]

Love the maths and trigonometry that went into this, beautiful design.

[@ukconstruction]

Thank you very much!

[@Morning_Rays]

Thank you for your videos. I am a newbie and learning a lot just by watching your channel. I have some questions please 🙏Q 1. Does the scarf joint to lengthen the ridge always have to be on the centre of the ridge length? Q 2. @8.25 which app is that you are using to position birds mouth on the rafters please? Q 3. How do you measure the length of props that you drop under head plate so that they fit snugly under the plate? Thank you 😊

[@zeez9053]

You seem a nice lad very clear voice easy to understand and learn from 👍🇬🇧

[@AsadMulla]

So exciting to see a new video on the big build series

[@rossmorrow3013]

What Craftmanship, and superb apprentices!

[@NSResponder]

Looks rather luxurious to frame your roof under a temporary roof, but I guess you really need that in the UK.

[@jonylevitt90]

Great work. Love to work on a roof along side you to sharpen my own skills as a carpenter. Never to old to learn an easier way or better way.

[@philpearson1714]

Been watching them building a house in the USA on the Lumnah Acres youtube channel. Their philosophy seems to be quick and dirty and yours quality first. Guess which build will still be there in 100 years or even more?

[@SirAlanPartridge123]

Robin i would love to see what that device is you made to hold your rafters together before allowing you to push it free when lifting your ridge up and in. I always enjoy learning new tricks. Great video again by the way 👏

[@carolewarner101]

Do you have a video showing how you make those jigs that allow you to marry up those rafters but then they slide right out when you push the ridge beam up in between them? That's a clever bit of work...very useful. Also, it looks like there's a significant gap between the top of those engineered ridge trusses and the bottom of the ridge board that's already in place when the engineered truss is resting on the weight bearing wall...how do you deal with that? Many thanks.

[@ukconstruction]

The truss is propped up and shimmed with ply packers until it presses tight under our ridge, from memory this can be seen in subsequent videos, the small jigs that you mention are really helpful!! I will make a video in the coming weeks

[@jacannon9147]

Great channel robin, bites for ashlar wall on rafters look too big, max 1/3 depth, have renovated and replaced roofs where this has occurred at wallplate level causing rafters to split and sag

[@peterwooldridge7285]

1/3 is the maximum set by our framing standard in Oz

[@ukconstruction]

I have a video coming all about bites or birds mouths as we call them and the theory behind the size, In some cases here in the UK we also use the 2 thirds rule especially if you are using small timbers such as 2 x 4 it is critical then as the timber is weakened by the birds mouth especially if the foot or eve is long (The section past the wall plate supporting the facia boards etc) when you get up to the size of timbers we have here you have the benefit to create a birds mouth that will take better fixing and indeed hold the member plumb tight and well seated, look out for the video!!

[@MrJimjam2011]

With a engineered roof or a trussed rafter roof we do a shear check on the birds mouth to ensure that the design still works. So while we sometimes work to 1/3 depth its not set in stone. At the eaves overhang the design check assumes a fully loaded roof with a man load at the end of the overhang.

[@carl4406]

Educational, fascinating and well explained as always. Quick question if I may Rob, what is the height of the overall roof structure as a whole structure and then with the framed out ceilings i.e. the lived in space?

[@ukconstruction]

From memory the overall height of the roof structure was about 3.6m and the finished floor to underside of ceiling collar was 2.4m

[@therealdojj]

I've watched that twice and think I'd still miss bits out It looks great though "work smarter not harder" 👍

[@Artthoujim]

Is it a policy to brace the opening when complete? And what’s the reason to do it! THANKS in advance

[@ukconstruction]

I will always brace any opening or frame and leave the braces for as long as we can until the structure is complete, its good practice and gives great strength

[@carl4406]

Hi Robin, would you generally always build timber frame walls like you did the supporting wall in this video I.e. building the wall stud by stud? Or would you build a entire wall and then fit into situ?

[@ukconstruction]

Hi Carl, This very much depends, if I am building a stud wall on top of new level joists and its load bearing then `i would do make it as a parallel wall and stand it up for speed, if as was the case here we are building load bearing stud partitions to support roof loads and we are building over an existing out of level structure then we would measure each stud for a really good structural connection

[@olafbigandglad]

I always thought ashlar was a way of laying stone. Is there another meaning?

[@robertbamford8266]

Same question. Except for me “always” spans the previous 90 seconds of checking google.

[@peterwooldridge7285]

That was my understanding too....clearly a UK quirk

[@amazing451]

Hi, Robin that roof is a real testament to your skill and ingenuity, were the rafters birdsmouthed at the ridge to allow the lattice frame to slot in between? 👏👏👏

[@ukconstruction]

Yes Kevin

[@pugachev70]

Great job, anyway about the scraf joint, have you tried to "slope" the shoulder (or all contact surfaces) , so it will enable to withstand against all x,y,z forces?

[@greggbutler9344]

Why is there no glue in the scarf joint ?

[@Toyotaamazon80series]

No need.

[@collcolin]

@@Toyotaamazon80series Yes but why is there no need what’s the theory behind no need for glue

[@Toyotaamazon80series]

@@collcolin If cut and fitted properly the wedges drive both sets of shoulders together. This results in a rock solid joint resisting loading and deflection along it's longitudinal axis. The rafter pairs lock the joint in and triangulate the roof. The same principles apply to something like a draw bored mortice and tenon joint in green oak framing. Those joints were never glued as far as I'm aware.

[@kennethcampbell2323]

How much load is the lattice ridge absorbing ? normally would smaller 3m-3.6m stud walls absorb the load??

[@tlangdon12]

Really enjoyed the video. So satisfying to see the first sections of ladder ridge go in. I'm just left wondering whether it was chance or planning that resulted in there being a rafter close to, but not over, the hole for the wedges on the scarf joint?

[@christaylor5291]

You would make out the rafter positions to make the centre of the scarf joint fall in between or a rafter just off to the side. I prefer to get the wedges centre to a rafter void so a rafter either side of it locks it all together.

[@gbwildlifeuk8269]

By the time Robin has finished complaining about his height, (or lack of it) and demonstrated the problem with the three giants, he'll soon get the title, "the two foot chippie"! 😊

[@darrenb3214]

I love your videos but they're not long enough. Maybe upload a raw video unedited to save editing time and do a condensed version like this for the people that want short videos 👍🏻

[@ronniewilson6597]

👍🏻😀

[@carpentryzucconiltd7875]

For sure, I do not want to criticize the operate of a brother, but to me, it is really hard to understand why, (having a detailed drawing like I have seen on previous videos) marking out pieces from 1:1 sticks, try them as templates rather than doing a few hours with the good old tables and calculate any piece of timber, add them to the drawing, cut them all on the ground (site or workshop) and fit all together like a numbered puzzle.

[@guyemmott4009]

Looking forward to the strategic product placements..🤔🙄

[@ukconstruction]

Got to pay the bills Guy, and afford to share my work for free mate!! In the Future I may go to a pay per view so I don't need the support of some great brands and product manufacturers but for now we will stick to this!!

[@ricos1497]

@@ukconstruction I'd rather see the product placements Robin. I'm guessing Guy walks out the cinema when an actor grabs a can of coke. Guy, you're essentially getting free instructional content. There were zero products (of a particular brand) used in this video that were integral to the work being shown, which is the same in most of Robin's content.

Guy - do you expect Robin to provide the content for free? Please explain how you'd like Robin to pay for the cost of filming & editing content without any kind of advertising / sponsorship?
