How To Calculate Gambrel Roof Rafters Lengths And Wall Heights Without Complicated Math Formulas

www.homebuildi... Visit our website today to learn more about roof framing, house design and home remodeling. In this video I will provide you with one of the easiest methods I could think of for laying out and calculating rafter angles and wall framing heights. Keep in mind that lumber sizes and other house framing components might need to be figured by an engineer and that the ideas in this video might not work for every project.

Thank you!! This video did help give me other options to build my Gambrel Roof I had 5 support beams one for every angle in my drawing. I chose a 3-angle cut verse the 2. Maybe applying your method with the Rig beam in the middle and the triangles on the sides may cut my cost and give me more storage space above. I chose this style so my wife can store her holiday stuff yet I keep my space at the bottom.

Very welcome

A great tutorial Sir, basically it's just a full size working drawing snapped out on the floor. I understood it all except I can't figure out where you got the 4-1/2" measurement at the wall plate. I must watch it again to see if I can figure it out, 👍🔨🇮🇪

great video building gambrel roof garage this spring

[@gregvancom]

Glad you enjoyed it

I like the video, but I have to point out in the first two examples the lines were drawn to the wrong corner point in the lower-right corner after you made a big deal about putting an arrow there to make sure we use the correct point. It was around 2:32 and 2:40. It was corrected by the time we got to 3:00.

Just what I needed for my roof
Layout

Awesome.

What would be the lengths of the upper and lower legs on a 14' wide bldg.

Hi we are building a new house with the gambler roof in New York city. Could you help us with the roof drawings based on your code?

I'm glad it helped.

How a bout room on the top of the garage can you please give us an idea about it size of 20’x20’ 🙏🙏🙏

[@gregvancom]

I will put it on my list, but it didn't win the contest. I will be showing how to build second floor over single story house.

I need help w a tall retaking block wall, can u giv me some advise?

[@lesliesweeney368]

Everyone of the three points must fit inside a semi circle, you can move them within the circle

[@ajsingh4009]

Great job

[@gregvancom]

Thanks

If I want to make a 36' wide gambrel roof, what are my options for floor joists without needing a center support? Would "I" shaped osb joists be the least expensive?

[@gregvancom]

Maybe the joist in this video or similar joist made out of metal.
ruclips.net/video/zvPQd95UHH8/видео.html I would install a beam in the middle to cut floor span in half to really save money if you can.

[@russianbot1779]

With this design couldn't you extend the rafter out past the walls to be able to add In a soffit?

[@gregvancom]

Yes, you would need to change the roof framing.

[@stevenleerobinsonjr5774]

Howz he gonna give you a reply that could be interpreted as a yes or a no? 😂

[@stevenleerobinsonjr5774]

It's a yes, simply extend your rafter ends

[@stevepierce5742]

Retaining wall

[@nestorini806]

❤❤❤❤cool

[@lesliesweeney368]

Plus when your laying out the roof you can not exceed 24' in width

[@khandam7709]

why not? I've seen 36' wide gambrel trusses. I guess if you just wnat to stick with 24' long material your point is valid, but one can easily get longer materials.
