Been involved in construction for several decades. Also taught the subject. Read many books and believed in simplicity. I must say that this is one of the best videos I have ever seen. Basic, simplistic and easy to understand. Kudos to you sir. You should be teaching in an Apprentice school. Absolutely great job. Beautifully illustrated. Thank you. A joy to watch.
I am new to construction, and I am builing a 12 x 16 shed. Why is there not a video with simple plans for a 12 x 16 simple 2 x 6 rafters joined with a gusset so iIdon't have to fiques out the math?
@@christinerameau885 you can order a complete 12 x 16 shed as a kit. No math. Just read the plans and nail it together. But if do not want order a kit. Then Math is necessary to measure and build it.
This is an excellent introduction to the construction of a roof, clear, concise and easy to understand. It explains the angles & geometry of the build and the reason it works the way it does. A superb example of how to teach. Well done that man.
I'm building a 600 square foot shop- and know nothing about roof rafters or how to design them, i have wached about 15 you tubes on the subject all say the same thing, follow these very simple math equations and you will know how to cut a roof rafter, well i say to them bull hunky. i was starting to pull out what small amount of hair from my head that i have left when i said i will try this vid but it's the last one before i call in a professional. Thank you thank you thank you. i finally get it and i feel very confident now that i can do this. the world needs more teachers like you,
This is probably the best video I’ve watched describing how to create a pitched roof for those not familiar with construction methods. Simple, well explained and easy to follow. Well done and thank you 😊 👍
I am not an experienced Carpenter however I do have some basic carpentry skills. I am in the planning process of building my own off grid house and was extremely confused and a little bit scared about building the rafters because of the complicated way everyone explains them. I feel like after watching your video I now have the confidence and understanding I need to successfully complete the task of putting up rafters. Thank you very much for the wonderful way you have taught this process through this video. Please keep up the good work and I will be subscribing
GREAT !!! I love how simple it can be made, ... leaving all those whom invest tons of money into tools out to dry... meaning... it's not as important to have all the fancy tools as one might think... just need saws, pythogaerom theorem, calculator pencil, paper or something to write on like wood to make note and marks and measuring tape, maybe chalk line... (clear water hose ends with fluid in them for leveling) ... that is all you need, and most important IDEA of what you want to do and how to do it studying these youtube videos really helps, one really has giant advantage that all the previous generations of builders never had... youtube is a coach is like having GPS maps in your car is helpful to all whom previously used paper maps and counting freeway exits to your destination for turn off connecting roads on the way to somewhere else... love youtube and everyone taking the time to teach, many many thanks! -tibor
I appreciate the detailed way you describe the "math" and the layout concepts. Don't change the way you are presenting your content. You method "cemented" the concept into my mind so well that I doubt I will ever forget it or need a review. My next stop is your link for more helpful videos. I am a fan.
This is a hands-on easy-to-use way to make rafters without all the math problems. It is a hassle free way to measure your angle & rise by eye. Any & all variations will work . This is a down to earth method. Great for the weekend carpenter, great job on your instruction. Thanks
The BEST, SIMPLEST, EXCELLENTLY PRESENTED guide to shed rafter layout on the Tube. Watched this a couple of times now and provided you make sure you are working from a square base, is fool proof. 👍🏾👍🏾
I have no experience in building anything. I decided to build a greenhouse to protect my plants from the freezing weather this winter. I was having trouble figuring out how I would make my roof. Your video has helped me figure out what to do to get a stable roof and how to cut my angle at the top. Thank you for making it so easy. Don't change your videos. I'm attaching to my house and using 2 x2 x8 boards and plastic to cover the roof and sides. Nothing is level or at right angles. Fun projects! Thank you.
I have to say that this video explained pretty much everything i needed to know about roofing and how to build one from start to finish. I've tried other videos but all they did was explain one part with out the other or they didn't include the small details such as adding the distance of the run and rise ALONG side with the base foundation. That is what made it make more sense to me in a way that it was so simple i couldn't believe i did some sample roofs of my own. Thank you kind sir!!
Truly the best (most intuitive, well structured, easy to follow) tutorial on rafters I've seen... and I've seen far too many before arriving at this, the last one I'll watch.
I have been wanting to build my own work shed for about a year now. After watching this I can say I feel very confident about going through with it. Thank you for your video.
been watching rafter videos for days now trying to understand it because I'm planning to do a roof by myself. This is the only video so far that didn't lost me in all the difficult mathematical steps.
Amen! I read through most of the comments so I will echo most of what's already been said.. After investing in a "Calculated Industries Magical Calculator" (and getting even more confused) This method and the way its explained is certainly in the top 1 percent!! Now going forward it will so simple.. Thank you for your teaching! I totally believe Jesus would give you two thumbs up!! Subscribed
Soon I am starting the shed project. I wanted to do gable roof. Have been watching a lot of videos and this one made everything crystal clear and made it easy❤
Excellent video! Nothing is too lengthy, very clear, practical, and useful. Math works the same way, but practically only easy if using the metric and decimal system, and no mistakes are made when marking the lumber. This makes it faster, isolates you from the material's dimensional inconsistencies, and inspires confidence. Superb, thank you!!!
That's a fantastic idea. I've been using the speed square and Pythagorean theory all this time. Luckily, I'm in the middle of another build and just have the floor down, so the timing is great. I'm going to use this, Thx!
I used your method to build make the trusses for my shed. By far this was the easiest method from all the others I’ve seen on you tube. Writing out mathematical equations like others are showing is a waste of time. Thank you, thank you, thank you!!! Just taking the roof pitch and multiply it by half the width of my shed it took me 5 minutes….
I'm certainly not trash talking your method, i love the simplicity of your method. I'm thinking that if i showed this to the framing foreman, he'd say just frame the walls up and do it the way we always do it!!! Your slowing down production, time is money!!!
Dude I’ve never bother to comment ever before! So that should speak volumes I’ve been pondering how to make this type of roof for my kitty house before I try a building thank you so much made perfect sense & cannot wait till daylight comes to start building
Thanks for that , now I get it . Been pounding my head with all these other videos doing all this math . Your way is so simple and easy . thanks again . Greg
Thank you for the tutorial. Very simple and easy to understand. Unfortunately I checked your video after I installed the walls of 😊my shed but I was able to laid my rafters in my garage.
Keep keep keep putting information please! if the video is too long we can always fast forward! Your videos are very educational keep them coming!!! Thank you sir!
I can tell you right now I love the video and the longer I would choose to watch due to the fact it's more information that you're going to be able to teach me I'm 50 years old but in this industry since I was 17 years old I know mostly everything that there is to know except brilliant ways like this following the rules of carpentry makes this one of the most efficient ways I've ever seen in my life thank you very much for taking the time and educating me I can't wait to see what you have next
Working on kingplate today..up and down ladder..foreseeng the setting of roof trusses ..next part of process..full sun etc..doing the work on the pad is so helpfull..thank you for sharing..i know this is great..it just went to"FUN"..after watching this video..also the others etc
@@gregvancomif I may sir I am a 65 year old retired firefighter with absolutely zero construction experience. I love your videos but I'm just trying to put it in practical application with my brain power. I am actually trying to put my pickup truck in my trailer undercover and I am looking to make a 20 ft x 20ft shed type building with no front doors at this moment. I'm just looking to back in my trailer and my truck to be under roof and my riding tractor in my backyard. I was thinking about just having a company deliver enough gravel to give me a base to drive my vehicle on. I did want to give it three sides and a roof and I am trying to decide between making trusses or just doing this ridge board with 10 ft Rafters on each side. I would like to not have any wood coming down from the middle to the ground. I was thinking of putting up four by fours in the four corners and one in the middle on each side but I wanted to have an open area in the center
one time i went to wooden boat building school where the craftsmen used a layout method called "lofting" to lay out all the curves to build a boat - all laid out on the floor. this reminds me of that. thanks for sharing.
You made a complicated project very easy to understand. Thank you so much for the video. I understand this will work for any size rafter on any size building. It all correlates with the size of building. Got a thumbs up from me!

I am a frame and truss detailer.This is a very good explanation!( we do precut rafters too).The only thing i can fault is perhaps a quick word on dealing with the natural bows of timber,and doing the layout on the middle of the floor.I have never seen a concrete slab that would be so accurate
@@gregvancom you probabaly right all i know is when we go to measure a concrete slab they are never exactly as per plan and the corners are often messed up

What an awesome compliment and I myself started full time when I was 17.
Way to go. Forget the fancy maths. Just snap some lines down and see it on the low down first.

After doing the "math" I took your advice and laid it out on the driveway. Worked PERFECT. Thanks
Excellent!
Very clear, thank you sir
All the way from Belize central America, thumbs up to your video, it is so easy to understand, on how to cut roof rafters.
All right and glad you learned something new.
Love the building the rafters before the walls. I always build my walls then rafters after and its always been a pain in the ass lol
