Roof Construction ~ Extension Build #7

[@KurtMGibbs]

Roger's commentary is spot-on, as usual.

[@SkillBuilder]

Thanks Kurt. Some of our viewers find it intrusive but I try to ask the questions I think will come up in the comments.

[@KurtMGibbs]

@@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!

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!!

@@SkillBuilder tea in bags!

[@SkillBuilder]

@@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.

[@alexbekele8945]

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.

[@Aaron-gl8cm]

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.

[@ChrisHow]

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 🤓

[@beardedsailor5890]

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....

[@jaser461986]

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. 👍

[@alistairbiggar6830]

[@jimwulstan8592]

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.

[@jeffreywarner6792]

Just the intro is a good lesson. When i was at school many kids said something like "I'm going to be a builder, why do I need maths?" Now, I will not not be negative to the kids, but maybe the teachers should have had a few site visits so that could answer the question with good context.

[@garyevans718]

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.

[@Ultimate-roofing-square.]

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.

[@iestynjones5796]

Great video guys. The hip cut is different because the hip doesn't go straight up the slope. Think of it like walking up a mountain, if you walk straight up you're travelling at a steeper angle than if you traverse the mountain.

[@SkillBuilder]

Hi Lestyn Thanks for that but Roger was asking why the hip difference was not a constant? It varies according to the degree of the main pitch but it is not a set amount. It varies by a degree or two. That is what keeps him awake at night.

[@iestynjones5796]

@@SkillBuilder That's because trigonometric functions are not linear (they're sinusoidal) . A change in the main pitch will not produce the exact same amount of change in the hip.

[@rocketmunkey1]

Having done a lot of hip roofs years ago working for my Bricky Dad on extensions, I remember being puzzled by the strange 45 degree hip rafter anomaly, the reason the angle "appears" less than 45 degrees is if you held the rafter square flat and level hovering above the rafter, as if the bevel angle was cut at 90 degrees, and eye it down, the cut is at 45 degrees, but as you lower the rafter squares angle to sit flat on the rafter, the bottom edge rotates inwards, as does the diagonal edge progressively along its length from 0 at the top point against the hip, to the maximum distance on the bottom edge. So as you rotate it down to sit flat on the rafter, the diagonal edge moves inwards at its bottom corner but not at the top, changing the angle of the diagonal edge on the horizontal, giving the appearance that the angle isn't 45 degrees. Its the Angle you are holding the rafter square which is changing, not the 45 degree Hip cut, Hope I've made sense ;-)

[@janeweedon6335]

Yep, hubby built our extension roof with ForgeFast torx 6 x 150's (he says...). Doesn't use anything else now.

[@Mastertradeskills]

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

[@Tom_Hadler]

Square root of 2. It's not difficult is it!

[@livingladolcevita7318]

nice one guys. Have to say though I didn't have a scooby when he started talking about the square. Like French he was talking too quick to understand lol. Glad to say that the point about connecting the floor beams across to stop roof collapsing confirms other vids I have been watching about loft conversions. I am not saying James is wrong but other vids say that the cross member at the top near the ridge is to resist roof lifting and not sinking. I may be wrong.

[@shanegent5804]

Beautiful job and top attention to detail as always 👍…ya can’t beat hardwood decking, I’m not a fan at all of the flake timber look that do mark up regardless of saying scratch resistant.

[@nickhaley4663]

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.

[@grahams6690]

another excellent video.

[@jayfallows5749]

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.

[@ETB9090]

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 👍

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!

Any tips for setting the wallplate height when trying to align an existing truss to a new traditional rafter? Basically extending an existing roof longer but with a different build-up.

[@Ultimate-roofing-square.]

It can be tricky. Usually you need bigger rafters now days and if the new wall plate is in at the same height as the original one you end up with a big birdsmouth. If your original roof is trusses it may help.
