Find any rafter angle with only a Speed Square and Chalk Line!! 

You are the answer to my dreams !!!!! I'm a 67 yr old female DIYer who barely passed Calculus 101 and have struggled with numerous renovation projects since then. You just saved me a ton of money if I had to hire a tradesman to rebuild my mudroom and exterior planter boxes! I hope your channel continues to grow exponentially :)

I just want to say thank you. I'm ready to put rafters on a place I've been building . Everything was whithout plans so I'm not able to use common rafter angles this helped me a lot saved me hours of watching anymore videoes. I was really stressing till this video.

Sheesh, so simple to explain. I looked for multiple videos to find this angle, and this was the best. Well done sir. Thank you.

This is the practical knowledge young men need, keep up

went trough like 10 videos and all I was looking for was a method to accomplish this. great video thank you!!

Great info, Chris. Easy tips to use. Thank you.

Well done 😊..nice and simple..😊

Thank you. You just clarified 3 books and schooling in 1 minute..lmao😂

Nice tip, love your channel!!!

Awesome video needed this 👍🏼

I must watched your video at least 16 times and I must say I'm a bit confuse, I see how you obtain the 9, that was easy. What I'm still trying to figure out is where the 12 come from? Somebody help me out please!

Wow Thank you! That is so helpful!!

Excellent and quick!

How do you account for the birds moth cut because the angle will change slightly.

I was searching for this information for weeks. Years of typhoons, Earth Quakes, Monsoon cloudburst heavy rain, moisture wood rot means it is DIY replace Roof TIME! New King Rafter, all Vally rafters, but cutting the valley rafter ends for accuracy was confusing to my 80 year old brain. Now with my Chinese Speed square, short bubble level I am on my way to the attic. ,

Love it

Thank you for the video.

Right on, Chris. Hey, whatcha looking at?

dont forget to say read the opposite side of the line where you were pointing to find the pitch so its not inaccurate.

great style

What is the run & rise?

The Rafter King!!!!

Thanks. Everyone else was telling me to find the square root of blah blah blah.

Thanks for the video. Like 👍

TY

Thank you!

I was thought like this a LONG time ago & it's still the best method 🤝

1:21 how does that convert to degrees please. Really helpful videos thanks.

Hey man! Awesome video. I'm trying to repair a roof joist this was super helpful for the ridge board side but I noticed the side attached to the top plate ( sry if I got carpentry terms wrong I'm an electrician) is cut as well at an odd angle and I'm wondering do I just mirror the angle I cut for the Ridgeline? Cool video though. Short and to the point. Thank you

Dude NOBODY else made a video showing this, it was always some other setup or wack math thing, thank you very very much

CH Hanson makes a speed square, which they call a "pivot square" for this entire purpose. No need of a plumb bob with there's.

WOW! The simplest things I just didn't know. thank you.

Is the rafter sitting on the ridge board?

hi could you just not draw a level line (vertical ) with a spirit level instead of hanging a chalk line and then drop the square on it ? it should pivot and give u the number when the square touches the pencel mark thanks
