Different roof styles have evolved to meet various needs. Every house and commercial building has to have one that fulfills its requirements. Other factors to consider are cultural norms and architectural influences. The designs and shapes of the structure will differ from one place to another. The important thing is that the design is able to provide full coverage for the house to protect the interiors from the changing weather. The look should also match the rest of the home. Functionality must be considered as well including insulation and ventilation. Let's go through the most common roofing styles below:
Gable Roof -- This is a common design that features a triangle with the highest tip in the middle. Although it's good for draining water quickly, it is susceptible to damage due to strong winds so those living in coastal areas and high places may want to avoid it.
Flat Roof -- This is usually found on the tops of commercial buildings. Simplicity and functionality make it a popular choice. Construction is quite easy as there are no limits on the surrounding walls. A small pitch is introduced to help water move to one side. Despite this measure, it can be a time-consuming option due to maintenance requirements. Water tends to pool and debris can accumulate quickly. It can be feasible in dry areas and tall structures.
Green Roof -- This is a version of the flat roof with additional ground cover that makes it suitable for plant life. Water does not seep through to the other side. Plants can be placed on the surface without worries about the roots wreaking havoc on the roof. It is also possible to use artificial glass as the material for such a project for the added benefit of transparency, especially if the interiors offer a great view.
Mansard Roof -- With this configuration, there are four distinct slopes instead of the usual two. One pair is more dominant in that they occupy a larger area and have a greater slope than the other pair. This is based on classic French design and was developed with the goal of having more interior living space.
Sloping Roof -- This is a general category encompassing all designs with tilt to any degree. This is what most would expect to find in homes as it provides owners with a guarantee that rain water will drain quickly and debris will fall down to the ground.
Hip Roof -- This is a variation that features four slopes that do not meet at a point or a straight line. Instead, it is as if the middle of a pyramid has been cut halfway and a square is left on top.
Skillion Roof -- Unlike the other designs, this one revels in its asymmetry. There is a singular slope that goes from end to end. Therefore, the walls are built to different heights. No ridges are visible. Getting the orientation right is extremely important.
Pyramid Roof -- Whereas the hip roof was sliced, this one retains the full pyramidal structure including the central peak where was slopes meet.
Shed Roof -- This option features a fairly flat design that has a bit of a pitch to help with water drainage. This may be considered for house extensions.
A-Frame Roof -- With this design, the walls and roof merge into one. As its name suggests, the roof starts from the ground and rises up to the top where it meets the panel from the other side. This is used in many cottages and churches due to economy.
These different roof styles all have their pros and cons. It is up to each homeowner to select the most suitable one for the current circumstances.
