What is a hipped roof?
A hipped roof or a
tent roof is a type of roof in which all four sides are sloping.Two of these sides cover the
front and back of the house and the other two, the sides. This is
unlike the typical gable roof in which there are vertical sides or
gables.Although the gable roof is more common in India, a lot of
bungalow-style houses in Delhi, Mumbai, Bangalore and Rajasthan
utilise the hip roof design.
What constitutes a
There are four main
elements that make up this type of roof. These are the ridge board,
common rafters, hip rafters, and jack rafters.
Ridge board- This is
the uppermost part or edge of this type of roof and is used to nail
the common and hip rafters in their place
Common rafters- These
are used to centre the ridge board in the building, set the roof
height, and locate the ends of the ridge. Commons run from the ridge
and down to the top of the exterior walls. Common rafters are the
largest components of such a roof assembly
Hip rafters- These are
nailed at a 45 degree angle to the ridge board and run down to the
four outside corners of the building. Hip rafters are critical to
give this type of roof its peculiar form and arrangement. These
rafters are also used to nail the top of the jack rafters.
Jack rafters- These
are typically the shorter rafters and are nailed to the hip and slope
down to the exterior walls.
Which type of roof
tiles can you install on a hipped roof?
Similar to a gable roof,
the hipped roof can be covered with multiple options. Prominent
among-st them are wooden shingles or Asphalt shingles. When deciding
to choose the best option for your home, don’t forget to consult
with a roofer.
Pros- These are
considered as a popular roofing option for their attractive design
and natural appearance and are typically known to increase the
home's value. They also extremely durable and are known to last about
5 to 10 times longer than typical shingles. The average wood shingled
roof can last 30 to 60 years if it is maintained properly.
Cons- They are
expensive and can cost up to 5 times more than composite or asphalt
shingles. Installation is not simple and often users have to pay
substantially higher for professional assistance. They are also
susceptible to infections and moulds that might develop due to
factors such as high moisture. The roof will also need periodic
chemical cleaning and preservative treatment to protect the structure
from long term exposure to environmental hazards.
affordable and provide a decent level of protection for anywhere
between 12 to 17 years. They are easy to install and are available in
a variety of styles and design.
Cons- They can get
damaged if installed at below freezing temperatures. Cheaper grade of
shingles such as tab-3 are susceptible to wind uplift while they are
also not resistant to extreme temperature fluctuations. They are not
environmentally sustainable and demand regular maintenance and
What is the
installation process of a hipped roof?
-The first step in
framing a hipped roof is to find the run of a common rafter. Through
this, you will be able to place the ceiling joists alongside the
common and jack rafters.
-After laying out all
common rafters the ceiling joists can now be placed alongside where
the rafters are to be located. Depending on the pitch of the roof you
may want to leave the end ceiling joist out until the hip rafters are
-Setting the ridge
board is the next critical step, this will enable us to know the
exact location of the hips.
-To set the ridge you
will require at least six common rafters cut and positioned around
their final location.
-You can begin by
spiking one rafter to the top of the wall next to the ceiling joist
then go to the opposite side of the building and repeat the process.
The carpenters involved in the process can just let plumb cuts rest
together to support the weight.
-After this, the ridge
board can be slipped into its place between the commons and nailing
it in its position.
-Now it will be
possible to place the king common rafters in place on the ends of the
ridge board. This way, the ridge can be locked in its final location
and temporary braces can be taken out.
-Now you can proceed
with setting the hip rafters. It is recommended to nail the bottom in
its place before fixing the top.
-Before starting with
the jack rafters, straighten the hip rafter with a string line nailed
on top and a temporary brace near the center to hold it straight.
-It is recommended to
nail the jack rafters on opposite sides of the hip rafter to help
keep it straight.
-The final step is
installing the fascia prior to installing the sheathing.
Pros and Cons of
Hipped roof and Gable roof
A hip roof is a lot
more complicated to build compared to a gable or flat roof due to its
complex truss and rafter structure. Due to their geometry, gable
roofs are relatively easier to construct and hence are also slightly
cheaper than hip roofs. However, hip roofs are sturdier (which is
great for areas with strong winds) and require less bracing than a
gable roofs, but at the expense of losing attic space.
