Hip Roof Erection Procedure

The procedure for the erection of a simple Hip Roof

[@carpentryandwoodwork2018]

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 Thomas, thanks for that great explaination, it is great to hear how things are done in other parts of the worid.

[@samuelalbritton2224]

Excellent video man. Thanks for your time. These individuals who leave negative comments about your free help blow my mind.

[@Buildsum]

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.

[@aniton11aniton11]

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

[@Buildsum]

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.

[@BigJProductions]

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)?

[@Buildsum]

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

[@hondaguy9878]

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.

[@Buildsum]

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. kzbin.info/www/bejne/q6e2pnegeZeNqdE

I need the software you are using please 🙏 thank you

Hi Eddy, I am using SketchUp which you can get free access for if you register for an account. www.sketchup.com/products/all

Hi.. . In which software you are doing working?

Hi Mate, I use SketchUp for all my drawings

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

[@Buildsum]

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 kzbin.info/www/bejne/i3e7coR5aK6DnMU Hope this helps

[@modemaranquiles5760]

What do you call that small brown rectangle inside the ceiling perimiter?

[@Buildsum]

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.

[@nikoscuatro7251]

Do you put the purlins inside?

[@Buildsum]

Hi Mate, yes the purlins go inside the roof under the rafteres

[@nikoscuatro7251]

@@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?

[@camman61]

what is the size of the roof ?

[@Buildsum]

What ever you want it to be.

[@83170mimi]

What about accessories?

[@Buildsum]

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.

[@vphonetastic9384]

Fantastic presentation

[@Buildsum]

Thanks Mate, I'm glad you like it.

[@szeale]

hi is it possible to remove the joists between the 2 beams? This would allow for a high central ceiling area.

[@Buildsum]

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

[@jonienglish3231]

do you actually need perlins ?

[@Buildsum]

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.

Hi Joni, the creeper rafters are the same sectional size as the common rafters just shorter in length.

[@Buildsum]

Hi Roger the collar ties go on every second set of rafters about halfway up the rise of the roof.

Hi Sam, Thanks for the suggestion i will see if i can do it in future videos

[@edthompson9337]

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!

[@Buildsum]

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.

[@Buildsum]

This video goes into the setout in more detail kzbin.info/www/bejne/mnnXq5Roma6Gp8k

[@edthompson9337]

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.

[@edthompson9337]

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!

[@Buildsum]

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.
