HOW TO DRAW A HIP & VALLEY ROOF
Example 1 Example 2 Example 3 Example 4
As you can see, this is a floor plan
layout of a house.
Note the 2 different widths of the
walls.
One wall is 4000mm (4 meters) and
the other 3000mm (3 meters).
These can be any value depending
on your floor plan, but for the
purpose of illustration, we will
follow 4 meters and 3 meters as
illustrated.
To start drawing in the hipped roof,
draw lines at 45 degree angles from
all the points on the roof as shown
in blue.
The internal roof lines are called
valleys and the external roof lines
are the hips (as shown).
As you can see, the 2 lines to the
top left of the image are just drawn
in approximately. We will
determine their length in the next
step.
All the other lines making up the
hips can be calculated by joining
them where they intersect.
In this step, we add in the ridge
lines starting from where the hips
that are established join.
We can now trim off the valley line
and hip line lengths that were
unknown from the previous step.
Now we can draw in the last hip to
complete the roof.
Plan
This is the finished roof showing
the fall direction of each of the roof
planes.
Example 2
As you can see, this is a floor plan
layout of a house based on the
previous example layout, but with
an extra piece added.
To start drawing in the hipped roof,
draw lines at 45 degree angles from
all the points on the roof as shown
in blue.
Now we can draw in the ridge lines
as shown.
In this step, there are dashed lines.
The 45 degree angle lines represent
the hips.
The other 2 lines (the horizontal
and vertical line) are there to make
an imaginary box. These lines help
to show you where to start the hips
from.
This is a good method for working
out roof designs. Try and work out
pieces of the roof into rectangles or
squares to aid in working out roof
line placement.
In this step, we can draw in the hip
lines and ridge line.
Delete the temporary lines we drew
in the earlier steps as shown dashed
in red.
This is the finished roof showing
the fall direction of each of the roof
planes.
Example 3
As you can see, this is a floor plan
layout of a house based on the
previous example layout, but with an
extra piece taken out.
To start drawing in the hipped roof,
draw lines at 45 degree angles from
all the points on the roof as shown in
blue.
Now we can draw in the ridge lines
as shown.
In this step, We have to draw in
some dashed lines.
The 45 degree angle lines represent
the hips.
The other 2 lines (the horizontal and
vertical line) are there to make an
imaginary box. These lines help to
show you where to start the hips
from.
This is a good method for working
out roof designs. Try and work out
pieces of the roof into rectangles or
squares to aid in working out roof
line placement.
In this step, hip roof is drawn in
purple color from the previous steps
working out, and also deleted the
temporary dashed lines from the
previous step.
In this step, we have again drawn in
the temporary lines of the hips and
the vertical and horizontal lines for
the imaginary box.
In this step, the hip lines have been
drawn in and the temporary lines
shown in red can be deleted.
Now just draw in the ridge lines.
This is the finished roof showing the
fall direction of each of the roof
planes.
Example 4
As you can see, this is a floor plan
layout of a house based on the
previous example layout, but with an
extra piece taken out.
This time we are going to approach
the roof design a little differently.
We have created a series of coloured
rectangles. Imagine each rectangle as
its own seperate roof.
This is how we are going to work out
the roof, in pieces, that we will then
join together.
Here we have started creating hip
roofs from 4 of the colored
rectangles.
Now let’s tackle the biggest
rectangle, the green one.
In this step we have added the hips
and also valleys.
In the next step, we will merge the
roof lines together.
Some parts that are shown now that
intersect will need to be erased to
form the proper roof line.
In this step, the dashed grey lines are
to be erased.
The blue lines are the connecting
pieces to merge the different roofs
together.
Now we will work on the last
rectangle.
Add the hips and valley as shown.
Erase the grey dashed lines.
This is the finished roof showing the
fall direction of each of the roof
planes.
