Roof Framing (How to Install a Ridge Board & Rafters) // Roof Framing Part 4

Sharing buttons:

okay so we've done a few things since

we've laid out our ridge board will talk

about the ridge board here first so if

you remember we did our 24 on center

layout and what we've done is we've

transferred those same layout marks to

the back side of the ridge board and

we've also installed our rafter hangers

these guys are pretty simple they're

very similar to joist hangers you just

throw them on the 24 on center and fill

every nail hole with a joist hanger now

those are going to come in real handy

when we start laying our rafters up in

place I'll just be able to tack them in

place with some more joist hanger nails

if you've noticed we've also installed

our ceiling joists for the interior of

our our home here so this kind of serves

two purposes one as you can see we've

installed scaffolding it's basically a

good platform to walk on if you have a

little bit larger of a home and you

can't span your ceiling joist quite yet

you can set up scaffolding along the

ridge or if your peak is just way too

high you may have to set up some

scaffolding before our case here the

rafter or the ceiling joists serve as a

good scaffolding just a quick safety

note we do have a 2 by 8 that we're

walking on and we've screwed it down in

a few places just so it doesn't shift

that's really important when working

with volunteers and for your personal

safety and we've also installed two two

by fours on the ends those are just

temporary so they're just fastened down

until we get this roof framed the second

thing that these ceiling joists do is

remember when we straighten our walls we

wanted to keep our walls nice and

straight this is a good double-check to

make sure that they're perfectly

straight we know that our ceiling joist

for this building are exactly eight feet

long so we lined up the ends of our

ceiling joist with the front of the

double top plate here we fastened them

down and then we made sure that they

were perfectly flush on the back side if

they weren't perfectly flush we knew we

had to do a little bit of adjustment we

turned out pretty good with this project


our roof is ready to be framed so now

that we have our ridge board laid out

and our rafter hangers in place we have

these two two by fours on both ends here

those are just a good idea that are like

helper hands if you have a building a 16

foot or less usually you have 16 foot

material these are just a really good

way to hold the ridge beam so you don't

have to use an extra pair of hands if

you didn't have the capability of doing

this you can just have a couple people

on both ends holding the ridge beam on a

ladder so all right if you remember from

earlier we laid out all of our rafters

these are our common rafters we have our

plumb cut at the top which is going to

meet our ridge board here we have our

bird's mouth right here towards the

bottom and then we have our plumb cup

for our fascia board and those are going

to fit on here sitting right on our top

plate I'm going to meet our ridge board

right at the top here and of course

they're going to be on our layout inside

our rafter hangers here but I just

wanted to show you guys a little bit

closer here if you remember I had that

bird's mouth cut from the outside of the

sheathing here to the inside of the

double top plate that way we have plenty

of surface here for using for fasteners

and that fits all the way from the

outside of the sheathing to the inside

of the double top plate giving you a

good seat you don't you want to try to

avoid only having an inch or two one it

doesn't give you enough surface area to

nail and two that can kick out over time

and your Raptors can fall down so make

sure you have a good enough surface area

there for nailing all right so what

we're going to do now is I like to

install the outside rafters first that

accomplishes two things one we just got

this temporarily in place you can see we

have some quick clamps there if we

install the outer two here in the outer

two there that'll get this ridge beam

pretty much at the right height for all

the rest of them and we can do any final


there so what we're going to do here is

set this guy right on the outside and

place it in our rafter hanger here and

I'm not going to really focus on the

outside too much at this point I just

want to make sure that this point here

is nice and flush with the top and then

I'm going to tack it in place with our

joist hanger now all right this guy's in

place so obviously I have my my helper

2x4 here I can't quite nail through this

side but there's four holes on each of

these rafter hangers and you want to

make sure you fill every hole with a

with the nail I'll get these other two

after we remove the helper

all right we are in place so now I'm

going to go ahead and tack this other

guy in place AJ you want to take the

reins on this one AJ will grab it here

all you want to do the other one on the

opposite end would have to pass you here

same thing he's going to put it in place

and get those two nails on the outside

okay so AJ now has his rafter in place

and I'm now putting mine in place in the

back and I notice I'm about a good

three-eighths of an inch below my ridge

board that doesn't mean that my rafters

are at the wrong length quite yet it

just means that we're going to have to

adjust our helpers and make sure we get

this right in the right location so do

we have that drill that we had here in a

few minutes ago we had secured this with

a screw just to be safe

remove that screw and now I'm going to

have AJ running this quick clamp here

and I'm going to go ahead and put this

rafter in place and he'll be able to

adjust it where it needs to go ready

bring it down a little bit that look

good right there yep

all right so he'll tighten it in place

now go ahead and check this rafter into

place now it's important to remember

we're just working on the top here our

rafter tails our ends are kind of still

flopping a little bit so it might be a

good idea to have somebody on the ground

watching that so they don't accidentally

fall off on you all right so we have

these two guys in place we'll go over

here and adjust the ridge board on this


yep this one needs to come up just a

hair so AJ I'll release the clamp right

there looks good all right and we'll

tack this one in place okay so we have

our first four in here now

now our ridge beam is pretty much at the

right height what we're going to do now

is secure the two bottoms and that will

make sure that this is right where it

needs to be and then we can go ahead

install the rest of the common rafters

here so I'm going to show you real quick

on one how we attach these guys at the

bottom come to the front here and what

we want to basically do here is see how

we're a little bit away from the wall

here we want to make sure that this

plumb cut of the bird's mouth is pushed

real tight up against the wall sheeting

we don't do that on all of them our

ridge is eventually going to be really

wavy and that just doesn't look good

with the final product so I want to

really take our time and make sure that

we have all these guys set nice and

tight up against the sheathing so what

we're going to do here is do a toe nail

right through the bird's mouth here into

the double top plate and I know a lot of

a lot of communities have different

codes requiring different fasteners for

their for their common rafters so it's a

good idea to check your local cold for a

nailing pattern I typically do two toe

nails on one side and split the

difference on the other side with a

third toe nail so I'm going to get the

nail started here

all right so I'm looking at two things

here I'm wanting to get it nice and

flush against the sheathing and I also

want to get this end one nice and flush

with the double top plate on the outside

so what I'm actually going to do is I'm

going to actually start it a little bit

further this way and when I hit that

nail it's going to bring this rafter

into right to where it needs to be nice

and flush on this outside all right

start it a little bit too far back but

got it flush do a second tone out here


so we've got these two on this side

we'll do a third on the other side and

then we'll continue to do the other

three that we have put in place here

after we get those pores secured we'll

go ahead and put the other five on each

side right up against our ceiling

rafters here and then our roof rafters

will all be put in place okay so we got

all of our common roof rafters in place

here we ended up and put all four nails

and each rafter hanger here and then we

also nailed off each bottom we have one

last one here that I just want to give

you a quick demonstration on how we

nailed off the bottom here so basically

you just we're going to use some 16

penny nails

a little unorganized with my belt here

and just like we did on the end roof

rafters here we're going to do a couple

toenails just put them in place one more

okay so we have our bottoms nailed off

and then the only last thing to do here

is to finish nailing off right here at

the ridge beam and what we're going to

do is we're going to do some more

toenails here and we're going to put two

on one side and three on the other side

right into the ridge beam and I'm going

to start this way so every once in a

while I don't know if you can get come

in close here but you can see our

rafters just a little bit off a layout

here if you if you have a rafter that's

a little bit off a layout you can fix it

right here with your toenails just start

on the opposite side that it's off

hitting the rafter on the other side but

it brings it right back into place and

then that nail will hold while you put

in your other two nails okay so now

we're connected at the top or connected

at the bottom we have all of our common

rafters in next we're going to move to

the gable and framing
