I watched a lot of rafter cutting videos but this has been the best one by far. Straight forward and clear.

[@BuildWithAE]

Thanks Wayne! Much appreciated, have a great week 👍

[@indigo50003]

finally a British video on roofing. Cheers very informative i wasn't left scratching my head like i was when watching a american video

[@BuildWithAE]

Hi Am AM, I'm glad you enjoyed the video. All the best, John 😊

an excellent video, well explained,and a British video on roofing yay, thank you.

[@timwyld573]

Handy tip there using two levels and a square to find the existing pitch if replacing rafters or doing an extension. Nice one

[@eddiewyc2175]

This is literally sooo good! What a brilliant explanation👌

[@TheGhost-gx5vd]

Thank god an English man telling me how it's done you have explained it excellent 👏 👌

[@ciaranduffy7259]

That was so satisfying to watch when you put the template onto the wall plate. Great fit. Good video.

[@BuildWithAE]

Thanks for watching Ciarán 👍

Really enjoyed your simple explanations, will be tuning in for more of your work. Wish I had gotten a trade like this when I was a lad, I can see just how rewarding a job this is.

[@BuildWithAE]

Hi Adrian thanks for your kind words all the best Tony 👍

@Ricardo Braden Thanks for your reply. I found the site on google and I'm waiting for the hacking stuff now. Looks like it's gonna take a while so I will reply here later when my account password hopefully is recovered.

[@jasperarian1789]

@Ricardo Braden It did the trick and I finally got access to my account again. Im so happy! Thank you so much, you really help me out :D

Glad you enjoyed it James, have an awesome week! 👍

[@MrJasdog107]

Good skill good explanation . Thanks. What about one on Jack rafters.

[@badsmell4009]

Set your circular saw to the pitch of the roof your cutting into and the seat cut of the roof that’s flowing into it 👍

[@stephenrobb3730]

Good video, thanks. So just to clarify… the user would need to know exactly what the pitch angle is before using it? Also what if the wall plate the birds mouth isn’t perfectly parallel with the ridge board all along the full length? Thanks

[@saltychannel21]

I cut the plumb cut first then use the offcut to get the birds mouth as that is already exactly the angles you need

[@Xavyer13]

Great

[@BuildWithAE]

👍

[@leduynhat92]

Gonna use this for engine storage how much space is actually in there?

[@SolidworksUnlimited]

Excellent demonstration perfect fit it will hold that wall tighter than my wallet in a depression!

[@BuildWithAE]

Haha thanks for watching SW! 👍

[@zocratiko]

Thanks for this video, I've just doubt on 2:20. What happens if don't already have any rafter placed on the roof? What must I measure?

[@markworthington3893]

String line 😁

[@ewanhobbs6297]

From the top of the ridge to the OUTSIDE top corner (top corner nearest the wall cavity that is) of the wall plate.

[@radishpea6615]

interesting video but how do you do the first rafter when you have no other rafters to take measurements from?

[@jamieodonovan1690]

Top of ridge to outside of your wall plate

[@yousefrezaie6572]

👏👏👏👏👏👏👏

[@py_tok5589]

NIVE LOVELY AND INSTRUCTIVE

[@BuildWithAE]

😎👍

[@itunesify]

How does putting in a birds mouth not change the pitch after it sits on the wall?

[@lukepcreaney]

Does this pass building regs and hold the structural integrity of the rafter? I know its meant to be 1/3 of the timber on a standard birdmouth why do you do the inverted instead of the traditional? Thanks

[@eddjordan2399]

yeah that looks a lot more out of the common than you should, is half allowed now?

[@ewanhobbs6297]

@@eddjordan2399 no 50% is way too much

[@nbnnajs1974]

Was literally about to say this, need a margin with an adjustable square

[@bramvanhautte5112]

How is that instrument called you are using for the roof pitch and drawing?

[@Chucktender69]

Speed square

[@mitchislam578]

Can I ask a question. How much does all this cost

[@KillilaghChurch12]

How do you find the angle of bird mouth if your building a new roof

[@kennedymashonganyika4399]

that should be indicated in the specs

[@101mossie]

I’d need 6 months in college before I’d understand any of this, it’s good tho 👍🏻

[@robevs100ok]

how to measure and cut a slot this video should be called

[@gdfggggg]

How do you know the length to cut the rafter? Cheers

[@BuildWithAE]

Hi Slashley gibbins you measure from the longest point at ridge to the back corner point of wall plate is a quick sure method thanks for watching all the best Tony 👍 oh check out the video rafter cut I have done you will see what I mean

[@gdfggggg]

@@BuildWithAE oky doky mate. Cheers

[@TheDublin47]

What you did't explain was was how to get the run of the rafter which is very important in a roof video

[@anthonyjmeli]

What is the purpose of the 6’ level. Can you no just put the square on the rafter and level it up with the 2’?

[@BuildWithAE]

Hi Anthony there are many ways to find the angle, Jamie shows a certain way thanks for watching all the best Tony 👍 have a awesome weekend

[@anthonyjmeli]

@@BuildWithAE thank you for your response and I hope you have a great weekend as well. I think to clarify my question is can you achieve the same results without the 6’ level and just putting the square on the rafter? I plan on doing a mock up this weekend and I will share my results.

[@BuildWithAE]

@@anthonyjmeli my apologies for not understanding please share Your findings sharing knowledge is a wonderful thing all the best Tony 👍

[@peterpumpkineater6958]

Is there a reason you had to cut so deep? Your bird's mouth cut looks to be over halfway through the width of the timber. Can't imagine that's to code?

[@BuildWithAE]

Hi Kyle the birds mouth is fine it’s an inverted birds mouth, thanks for watching all the best Tony 👍 have a awesome weekend

[@hn9598]

You get it a lot when having to line in with the adjoining property unless you have the luxury of being able to reposition the wall plate.you have to remember most old rafters were 3 to 4 inch so if they were working to a third of that for their birdsmouth that isn't a lot when transferred to the bigger timbers we generally use now which can be around 6 to 7 inch. We get it a lot when they used to just put a full seat cut with no birdsmouth and just nailed through the side of the ceiling joist to triangulate it. That can be a pain 🤔😁

[@hn9598]

Nice tidy job by the way a&e everybody loves a bit of Roofing. Are you Leamington based. Lucky sods if you are there's some great buildings there that you will get to work on proper craftsmanship and proper old detailing that doesn't get done anymore on many new builds these days.

[@81mooks]

@@hn9598 literally just finishing doing a roof over a flat roof..restricted with the over hang for fascia so no traditional birds mouth..seat cut only , 6x2 rafter 12° pitch. Talk about a pain in the hole 😂

[@DRJMF1]

Surely, better to just use the previous cut rafter as a template for the next timber to be cut (place the already cut one on top of the next timber to be cut and mark out the cut line), why bother re- measuring each and every tiber, duh ?Unless you plan to milk the job. However, some useful tips on accurate measuring technique. Of course before buying your timbers, ensuring they are straight (highly unlikely in expensive modern crap wood available in the UK).

[@jamieodonovan1690]

Let me no if you want yours doing I’ll milk yours 😂

[@dermotkelly6946]

This lad will be a top chippie , but take it from a 59yr old chippie don’t grovel about on your knees protect them, or you will suffer .👍

[@dielauwen]

I do not know why there is such confusion. It is simple geometry. And learn trigonometry.

[@BuildWithAE]

Hi dielauwen, It would be great if we could use trigonometry to work out roof rafters, but it's rare to find an old property like this in which the walls are perpendicular. Which means that using trigonometry accurately isn't really an option. This means finding the pitch manually, using methods such as this is generally the easiest way. Thanks for watching. All the best, John 😊

[@hn9598]

You can use that method if if its a new construction and all the levels are right.i don't think I have worked on many old roofs where you had the same pitch both sides. I was taught by an old boy who learnt his Roofing method from hand cutting pairs of hipped semi detached house in the 50 s and his way of working out length of rafters was with a bit of margin for error so to speak but it would work as it was from scratch and to his pattern. Handy to know more than one way in my opinion.

[@keithmilburn4866]

American roofs are absolute crap, in fact an American roofer wouldn’t get a job here
