I played around with a few ideas for my roof replacement last summer. I finally settled on factory-made trusses and I am very happy with the result. Two section roof 18.5' x 24' and 24' x 14'. This required 11@18.5' span trusses and 8@24' span trusses and cost me just over $2,200. My limiting factor here in Newfoundland was lead-time from the truss factory (about eight weeks) and it also drove up my cost as the largest factory here was 10 percent less expensive but the lead time was double.
Great teaching style. I am having a loft conversion done and had difficulty working out what was going to happen in my roof - feel enlightened. Thank you.
Very informative and well presented video. However, your use of the term Queen Post truss to describe the arrangement shown at 2:42 is incorrect. While this does indeed look similar to a Queen Post truss arrangement, the structure is not working in this way. This is because the vertical post you have provided is working in compression to support the purlin. In a true Queen Post or Palladian truss arrangement, this vertical member works in tension to support the main horizontal tie beam below.
Well demonstrated video on designing roof structure using computer modeling. It’s a great way to derive unique and durable roof designs. Thanks for sharing this informative clip.
When you say "of course we need one of these tie-beams for each rafter" I don't agree. I've seen a roof 6m long with two wires(doing the job of ties) stopping the lateral movement. No sag in the roof after 25 years. I know it's the custom but don't believe it is structurally necessary to have a tie for each rafter. I think the practice of using pre-made trusses has brought this into fashion. Excellent vid all the same, just a picky point. I've done a lot of building incl my own house. I've got a double carport with nine posts (3 lines of 3) and am thinking of taking the central one out and replacing it with a truss/collar/tie arrangement of some sort. That's what brought me here.
Agreed.. Assuming a roof with ridge board and depending on the width of the wall (top) plate - then you would only need a tension tie every 2-3 meters. (or more if the remaining rafters had 'collars' say half way up) The only value in multiple cross ties would be to support a loft or for ceiling fixing. Otherwise - good video
Thanks for uploading this summary. Is this part of a series and if so are other parts available? I'm researching how to design an open pitch roof for an extension that is 5m wide..
I am considering constructing timber shed 1.8 m wide and 4.8 m long using 2 x4 inch timber for the walls and rafters. Will I need rafter ties? Concrete roof tiles like on a house Thanks. Great video
Which of the two designs is stronger, if the width of the building is quite large, like 6-7 meters? Bigger, heavier logs, or the smaller, lighter repeated design?
Guys I found a website on which more then 12000 sheds plans available I am learning so much on their. the website is LatestShedPlans48.blogspot.com all you guys should try it....
Can you please do one on how truss rafter roof works and why it's needed and then how the roof can be adapted to make dormers with no truss webs? Would be great as you explain things much better then the others!
I really like your video. I build a small house of 6 / 4m and I build the roof now. I bought beams for the attic, they are 8 / 8cm, (the base of the rafters, the rest of the rafters are also 8 / 8cm.), They are placed horizontally on the walls (concrete blocks), the base of the attic. I'm a little worried they're not thick enough, I mean those that are laid horizontally. Can you tell me if they are thick enough? Thank you very much.
excellent video. One missing element though. The horizontal stability members to keep the trusses in alignment on intended centers. Could you add to your video please? Roof sheathing can be the element or timber members inside the trusses perpendicular to the direction of the trusses.
Thanks Jay; you make a good point. Hoping to do a whole series of bitesize construction (in my copious free time) - I'll aim to pick this up separately.
hi, this is a great video, very informative. i think, i may have a problem with my roof. it is a timber roof 6mx8m. there are a couple of very thick beams which are completely loose. if i took a video of it, could you have a look and comment?
Hi ya Great vid solent bird , I'm a loft convertor up north , apex lofts in google should be top hit if you'd like to check me out. I'm looking for something simular to this video to explain how i take a normal low pitched roof off and place attic trusses on. Im not sure how to get hold of you to have a chat. thanks woody
One of the most helpful videos about ceilings and roofs I have seen. Thank you for sharing this info with us.

What an excellent video, straight to the point and loaded with information, thank you so much for it
good stuff, and such a pleasant voice.
Great teaching style. I am having a loft conversion done and had difficulty working out what was going to happen in my roof - feel enlightened. Thank you.
I agree she was very easy to follow and listen too.

This was the information I've been looking for, thank you!
Sometimes we do roofs with a vaulted ceiling using a laminated Ridge beam and depending on the spans etc without purlins.
Great information and doubly useful with the nifty Sketchup supporting imagery. Love it.

Wow, great video! I have a mid-term in 38hrs, this helps a lot.
Very welxome, ShoesOnHands!!

Excellent video. I never new or heard how roofs are done. This is quick and to the point :-)

spelling isnt your strong poin either?
jolyon, wow

I have ceiling joists that are half way up the rafters. Is that a structral issue?

The video capture is done using Camtasia; the modelling with Sketchup.
Clear explanation! Brilliant. I am trying to Learn how to design roofs.
what if i got 3 load bearing walls, and make a stud wall from the midle of the house up to suport the ridge
Thanks for posting this video. Good basic info!
What program do you use for modeling, it looks nice
Very nicely put, very watchable,thank you,
excellent video. One missing element though. The horizontal stability members to keep the trusses in alignment on intended centers. Could you add to your video please? Roof sheathing can be the element or timber members inside the trusses perpendicular to the direction of the trusses.

Very informative guidelines especially for beginners.
hello im a complete beginner,what kind of programs i need to design my home ty
hi in the queen post is it possible to remove the centre cross member and if so diagonal support or straight support, thanks
Fortunately steel pipes with L-beams are forbidden in support scenarios.
10/10 one room How much cost please.. Inform..
i hate doing angle cuts with a power saw and a jig!
Very Good , so interesting .
Your voice is so charming~
great video..nice explanation
Very nice. Thanks
what program are you using???
Do it a school or company work in Ghana
great video!

What program are you using?
The model is in Sketchup and the video editing is done using Camtasia.
O.K. thank you
What's the name of the program you're using by the way awesome
She's using Sketchup.
@SolentBird, do you have this file available for sharing?
thank you
whats the program u use ?
+swiftgmx ady Sketchup
Why and how would there be a load at the peak where she placed the arrow? Ahahahaha. What does that simulate exactly?
Very nice

Stupid model, you have to construct two side wall just to support your roof
