Very good information and well explained! For some of the other viewers who are interested in roof construction in different countries or who may even travel to work in other places. On the point where the crown rafter meets the end pair of common rafters, in good practice, we would face this pair of rafters up with a triangular "saddle board" a type of gusset board for the hip rafters to rest firmly rest against to ensure that they obtain full bearing because the hips can sometimes have a plumb cut about 1/3 longer than the common rafter plumb cuts. The crown rafter in between is also built down with a triangular block of the same rafter thickness and this enables a longer plumb cut on the crown rafter similar in length to the plumb cut of the hips. Therefore we adjust the position of this end pair of rafters to allow for the thickness of the saddle board and the hip rafter length calculations still meet at the center of the roof on the plan. Where the hip rafter meets the wallplate it is standard practice for us in Ireland and the UK to notch the hip rafter over a corner tie, or dragon tie, a very secure tried and tested method.
Hi thanks for that video.question. Why are pearlings needed the roof will support itself without them (between installing the main roof and installing the pearlings)?
Hi Mate, the Purlins are there to support the rafters. The Purlins are supproted on struts that transfer the loads down to the walls. If you remove the Purlins the rafters will have to be bigger to carry the load. Hope this helps
A future DIY project Im thinking of doing is a (3.7 x 4.3) 4 post hip metal sheeted roof 'gazebo' with exposed structure (no ceiling lining) without underpurlins, However will add collar ties to the commons only. Is this possible as your model indicates underpurlins
Hi Aniton Yes that is fine as the rafters wont be supported. You will just have to make sure that you are using rafters that are big enough to span the distance without the need for the purlilns.
Hi Samuel, thanks for your comments, thankfully I don't get too many negative comments and I actually prefer the comment rather than just getting 'thumbs down' and not knowing why.
Excellent tutorials. Thank you for all your hard work. Would it be possible to get a tutorial on erection of Broken Hip & Valley Roof with a built in garage that's at a 45 degree angle? Sincerely.
Hi Mate, thanks for your comment. That's a pretty specific request and to be honest not something that I would be looking to do in the near future. The erection process would be the same it would be the layout of the roof that would be different. This series of videos may help with that. ruclips.net/video/uvSuDjD2Zso/видео.html
Hi, I am building a side extension. Front of extension wall is 106 inches away from existing house back end of wall is 78 inches away from existing house. It is not square but I need to build a hip. Please can you explain how we can achieve a same pitch hip without flat roof. I am waiting for your reply Thanks
Hi Jabbar, That would be an Oblique Hip then, All hips have to bisect the corner of the wall plates. This playlist should help you out ruclips.net/video/UFXAQC3IPfc/видео.html Hope this helps
Hi Mate, the rectangle is formed by the Purlins which are attached to the underside of the Rafters and not in the same plane as the ceiling, hope this helps.
Hi Mate, I would need the exact size of the building to do that. Here is the link to the video on how it is done, ruclips.net/video/a0SS8lwqf7g/видео.html hope this helps
Hi, you really dont need the ceiling joists at all if you dont want them, you could run your ceiling lining up the rake of the rafter until you get to the collar ties, or you could also beef up your rafters and do away with the collar ties as well and just have a raked (sloped) ceiling. Hope this helps
Hi Mate, Requireed accessories will differ from country to country, and even city to city, wind zone to wind zone. So they are just added as required for the local area.
Hi Joni, it depends if the material that you are using for your rafters can span from the plate to the ridge with out them. Or if you dont want a purlin you will have to use larger (deeper) rafters.
Ties to 4200 mm long for F8/MGP12 or higher stress grade 70 X 35 Ties to 4200 mm long for less than F8/MGP 12 stress grade 70 x 45 or 90 x 35 Tiess over 4200 mm long for F8/MGP 12 or higher stress grade 90 X 35 Ties over 4200 mm long for less than F8/MGP 12 stress grade 90 x 45 or 120 x 35
Hi Bryan, my email address is buildsum@gmail.com Please remember if you are going to have a trussed roof they have to be engineered by the manufacturer you can't just build them yourself. Also, I assume you have seen these videos, they show the different types of trusses and their position in a Broken Hip roof. ruclips.net/video/Zv90ml4gIbg/видео.html ruclips.net/video/Gdnl0im-Cug/видео.html
Hi Ed, i did mention that the 1/2 span was to the centreline of the rafter, which was all the detail i wanted in this video as it was just ment as an overview. Just another small point, to get the edge of the rafter you would have to deduct or add half the rafter thickness, not the ridge thickness. Thanks for keeping me on my toes anyway.
Further to my earlier post and your reply, none of the common rafters come to the centre of the span, the centre of the ridge sits at that point so therefore you would half to take half the thickness of the ridge away when calculating where the last pair of common rafters sit.
It's the same when you are working out the length of the common rafter, half the span minus half the thickness of the ridge, as the plumb cut of the rafter doesn't sit in the centre of the span!
Hi Ed, yes i agree, none of the rafters actually meet at the centre of the ridge and in order to calculate the length of the rafter you have to deduct half the thickness of the ridge however this doesnt apply when setting out the position of the centring rafters. The centre of all the members have to align with the centrelines of the roof.
Hi Jason, you need to have a look at this playlist, the Pattern Rafter videos will show you how to work out the required lengths of the members, then there are 4 - 5 videos on different methods of developing the 8 bevels required for the Hip Roof and then there are the 4 videos on how to work out the length of the Hip Hope this helps.
Please tell me that you’re building your own loft for yourself? Not going around selling yourself as a carpenter, taking peoples money and then spending half the day on RUclips trying to learn how to actually be a carpenter.

What do you call that small brown rectangle inside the ceiling perimiter?
Hi Mate, the rectangle is formed by the Purlins which are attached to the underside of the Rafters and not in the same plane as the ceiling, hope this helps.
Do you put the purlins inside?
Hi Mate, yes the purlins go inside the roof under the rafteres
@@Buildsum Thanks sir. The video shows the real way of Erection Procedure insitu, in the steps that the builder is going to follow to make the roof?
Fantastic presentation
Thanks Mate, I'm glad you like it.
Can I use this for my shed?
If I m building a 14x16 gazebo & I want 2 feet over hang what's the length of my rafters it should be?? Please let me know I m building one
Hi Mate, I would need the exact size of the building to do that.

Sorry mate, I'm not sure what fall you are refering to.
how did you make the video? very interesting.
HI Harry, Thanks for you comment, I draw and animate everything with SketchUp and then just do a screen recording as i talk through it.
@@Buildsum Thanks
what is the size of the roof ?
What ever you want it to be.
Watched all and down loaded your videos. Excellent work, I am in the trade. Thank you
hi is it possible to remove the joists between the 2 beams? This would allow for a high central ceiling area.
Hi, you really dont need the ceiling joists at all if you dont want them, you could run your ceiling lining up the rake of the rafter until you get to the collar ties, or you could also beef up your rafters and do away with the collar ties as well and just have a raked (sloped) ceiling.

What about accessories?
Hi Mate, Requireed accessories will differ from country to country, and even city to city, wind zone to wind zone. So they are just added as required for the local area.
do you actually need perlins ?
Hi Joni, it depends if the material that you are using for your rafters can span from the plate to the ridge with out them. Or if you dont want a purlin you will have to use larger (deeper) rafters.
@@Buildsum thanks for Reply

Awesome vids keep them coming
Thanks Sam
hi John, Do we need collar tie if we dont have underpurlins ?
+Roger Zhang
Yes
Buildsum what's the collar ties space then? Every how many rafters?
Hi Roger the collar ties go on every second set of rafters about halfway up the rise of the roof.
Buildsum how about the collar tie size, has to be same as rafter size? Thanks.
Ties to 4200 mm long for F8/MGP12 or higher stress grade 70 X 35
Ties to 4200 mm long for less than F8/MGP 12 stress grade 70 x 45 or 90 x 35

How much can a 1800 sq ft roof cost to have this done
Hi Jose
Mate, there are really too many factors to consider to give you a price
Great video if you could highlight your curser that would be good
Hi Sam, Thanks for the suggestion i will see if i can do it in future videos
Yours videos are Very interesting !
+Marcus Fungeri Thanks Marcus Glad you like them

Very slow CAD or whatever has been used, Minions have better tools.
The position for the last pair of common rafters is half the span minus half the thickness of the ridge, you forgot to mention that!

Can I use this type of hip roof in 1800 sq ft
Hi Mate, you can use this style of roof on any size building.
Thanks sir

What about the collar ties?
+Abby Normy Hi Abby Yes the Collar Ties should be installed directly above the purlin to every second set of rafters.

I need to build a 10x12 hip roof
Hello bro
every Chinese build long and wide is odd number.
You should film yourself actually doing a roof :) go pro or something, that would be ace
very helpful
