The roof style that gently slides from a central roofline is known as hipped or hip roof. When a hip roof slides in four directions from a central point it creates a pyramidal structure. In the late 19th century, hipped roof became very popular in Canada. One of the most notable buildings from that period, H. Vincent Meredith Residence, still stands in Montreal, Quebec. Its steep hipped roof is one of the most noteworthy features of the building. A hipped roof never seems to lose its popularity since those days.
Hipped roofs do not lack in variety either. Some of the popular variations of hip roof include:
Mansard roof – Mansard roof is a legacy of the baroque era in France. It owes its design to renowned architect, François Mansart. In Ontario, you will get to see plenty of public administration buildings and residential structures with mansard roof. Montreal City Hall is a prime example of a house with mansard roof. Beaverbrook House, built in 1877 and located in Miramichi, also showcases mansard roof.
Dutch Gable – Also known as gablet roof, this one merges a gable roof style with a hipped roof. The gable roof is constructed on top of the hip roofing.
Pyramid hipped roof – This one joins four equilateral triangles to a central point. The resultant boxy structure resembles a low rise pyramid.
Cross hipped roof – When two or more than two separate hipped rooflines meet at a central point, it creates a complex roof design. This one is typical to large houses built on sprawling private parks.
If you are planning to install a hipped roof in your house, you will need the following roofing materials:
* Lumber – Lumber is needed to build the basic structure of the roofing system or the roof trusses. Wooden roof trusses last for more than 50 years. They are aesthetically pleasing and sustainable. They are also capable of giving the entire structure much needed strength and stability. Lumber is popularly used for gable and hipped roofs. As an alternative to lumber, you may use galvanised iron for building the structure. Iron is as durable as wood. Roof trusses built from iron tend to be lighter. It is not unusual to use a combination of lumber and iron for building the primary structure.
* Materials for sheathing – For sheathing use materials like plywood, foam board, fibreglass or Oriented Strand Board (OSB). This will provide adequate roof insulation. Plywood and OSB tend to last longer than foam boards and fibreglass, but they are also costlier. Due to its durability and energy efficiency, plywood is generally used for hipped roof insulation.
* Asphalt shingles are needed to waterproof the interior. Wood and felt shingles are also used for this purpose. While all three are equally efficient for waterproofing the structure, asphalt shingles are more cost effective and available in almost every hardware store across the country.
* Concrete and glue are needed to fix the shingles.
* Most people like hipped roofs with roof tiles. You may use terracotta tiles manufactured for this purpose.
* You will also need nails and braces to hold the beams and rafter in place.
* Other necessary equipments include ladder, safety goggles, helmets and gloves. Tools like saws, hammer and measuring tape is also needed for the task.
The entire process of building and installing the hipped roof would cost you between $650 CAD and $800 CAD per square metre. This includes the costs of purchasing the raw materials, building the framework, installing the roof and paying the dues of the people involved in the project.
It is always better to discuss your design requirements with an architect. You may use homify’s online platform to find an architect for your project. An experienced roofing professional will help you in the actual installation process of the roofing system.
If you prefer the DIY way of building your own hipped roof, then follow these steps:
* Use measuring tapes to scrupulously measure base area. Accordingly, measure the correct length of the rafter and beams.
* Install the rafters 50 cm apart from each other. Alternatively, you may use pre-fabricated trusses for this purpose.
* Use braces and nails to hold the beams and rafters in their place.
* Cover the framework with plywood or your preferred sheathing material. Use nails to fix the sheathing material with the rafters.
* With the help of concrete and glue, fix the asphalt shingles on top of plywood.
* Now arrange the roof tiles above the shingles. You will need to use concrete to hold them in place.
Both gable and hipped roof are very popular in Canadian architecture. Both of them boast of versatility in design. Their legacies are rooted in history. Hipped roof as well as gable roof is suitable for houses in cold climatic regions of the country. Neither of them allows piling up of snow or water on the roof. Their sloping designs effortlessly slide off snow and water.
With the exception of cross gable roofing, a gable roof is relatively simpler to design and install. It is cheaper than hipped roof. Hipped roof has a more complex design. It is more expensive to install this type of roofing system. Compared to a gable roof, a hipped roof is safer for the houses in the windy areas of the country. Its boxy style does not easily unsettle it from its place even under stormy weather conditions.
