I don’t know why every second comment is where is robin, James did a great explanation of setting out a roof and he may not be robin but a genius in his own right. The guy can do pretty much every part of the building trade to a high standard and we still get to watch robin on his own channel.

@SkillBuilder 3 года назад

It is a natural but regrettable trait of human beings that they love to stir up conflict and make something such as a simple carpentry video into some kind of competition. The roofing square was around before any of us were born so nobody owns this information. The important thing is to pass it on. Thank you for your support.

This subject is just about the only thing I’ve never been involved with hands on over the past 49 years of being an all round builder/roofer. The way it’s worked out amazes me especially hipped roofs. I must get one under my belt while I still have time! The best explanation I’ve seen so far on RU-vid.

@christaylor5291 3 года назад

This is a version of stepping off along the hypotenuse or rafter length. Stepping off as far as I know always works across the run which is half the span. Your either a split the span and x by per metre of run.... Or step off which is across the run/ at right angles to the building using a metric square. The good thing about stepping off is you can set collar heights/pre determined purlins heck even steel work before the roof has been pitched. Great content as always. I suppose there is always more ways to skin a cat or a ferret whatever floats your boat! Stay safe all.

@SkillBuilder 3 года назад

They teach you that trick with the fence when you first go to College and it works a treat, some carpenters use stair guages but they are easy to lose. James chose the tape because it left the numbers visible, the fence obscures the detail when you are demonstrating. These videos aren't just thrown together.

@jimwulstan8592 3 года назад

The square on the hypotenuse is equal to the sum of the squares on the other two sides (Pythagoras). Forget all about that and all the calcs and just use the roofing square as shown, it will give you everything, Use a thin piece of timber instead of the masking tape so that it just slides from one postion to another with ease, all the cuts and the birdsmouth can also be taken from the same setting. If you include the ridge you will know where to cut it later. Great video5 stars

I use stair gauge to maintain my marks , I use the dimensions from the rafter square and multiply by the run and mark the rafter and then step it off marking each step with my board knife for accuracy , it allow ways works out , if not there is a mistake.

@Morning_Rays 2 года назад

Thank you 😊. One question for you please. If the seat cut can’t go above 1/3 of the timber, replacing 4x2 rafter with 6x2 for loft conversion would increase the finished roof height by 2 inches? Is that right? Thank you 😊

@Blue60 3 года назад

Yes, we picked 5 over 12 but you can do it in metric or degrees. It is the same deal, once you know that third measurement you are good to go.

@SkillBuilder 3 года назад

Lots of carpenters use fence made of hardwood or aluminium angle and it is shown in the City and Guilds carpentry books as a good method, you can also use stair guages to do the same thing but this is a video to explain how stepping off works and having a fence across the numbers obscures the very thing we are trying to show. We tried it.

@daihedral9269 3 года назад

That's a great explanation of stepping off to mark the length of a rafter, and it's important to keep craft skills alive, but now we all have calculators on our phones isn't it easier, quicker, and less prone to error, to use trigonometry to find the rafter length? Run divided by cos of the pitch or rise divided by sin of the pitch.

@SkillBuilder 3 года назад

Hi Dai You are right and James did say you can get a free app but a lot of people have asked us to have another bash at explaining this so we thought we would let James have a go and see if he could make a few lightbulbs go on. It is, in many ways redundant but it helps to understand what is going on and not just become a slave to the machine.

@thelegoloft5174 2 года назад

@peterbell4154 3 года назад

There is so much to the roofing square that measurement of 13 being the length of rafter per ft run take that on the body and twelve on the tongue and you have the side cut for a jack rafter and the top cut and bottom cut for the valley lay board.

Thanks. There still is 12” in a foot. The 13” is 13” of rafter length per foot (12”) of horizontal run, If it was a steeper pitch then the rafter length would be more, for example a 12/12 roof would be 17” of rafter length per foot (12”) of horizontal run. I hope that makes sense.
