Choosing A Flat Roof

Published: February 2, 2010

The flat roof has always been a popular choice in places where the climate does not tend toward snow or heavy rainfall. Unlike the pitched or sloped roof, the flat roof is a horizontal covering for a building, which is not positioned at an angle above the building.

Sloped roofs were specifically developed in order to allow houses to shed heavy rain, or snow, in order to prevent the extra weight and moisture from causing damage to the roof structure. As a result, this kind of roof has been most common in northern hemisphere countries, where such considerations were important for the structural well-being of the home.

In contrast, as we mentioned above, flat roofs are most suited to countries with dry, or snow-free climates. In South Africa, where rainfall can be an important factor, it is advisable to build a slight incline into a flat roof design, to allow water to run off. However, in most cases, the roofing material will make allowance for such run-off.

Flat Roof Waterproofing

Flat roof designs in South Africa are often constructed from corrugated metal or fibreglass, which incorporate enough of a slope to allow water to run off. However, a flat concrete roof is another possibility. It’s important to remember though that standing water can lead to flat roof leaks, and that, if possible, it’s advisable to make sure that your flat roof is waterproof by using one of the many available methods.

These include membrane coating, often covering a rubber coating, and can be chosen to suit your roof and your budget. Good waterproofing will increase the lifespan of your flat roof, and reduce the amount of maintenance that needs to be carried out over time. However, flat roof repairs, like repairs to other kinds of roofing, are an integral part of the maintenance of your house, and should never be neglected.

The Benefits Of A Flat Roof House

There are many advantages when it comes to building flat roofing. This is without doubt one of the most cost-effective methods of roofing, partly because it allows the full height of the rooms below to be utilised, and partly because it reduces the quantity of necessary roofing material.

Another advantage to flat roofs is the ease with which solar panels can be affixed. In our sunny climate, this can be a great advantage, albeit a type of modification which is not yet widespread.

Although flat roof roofing can generate a lot of heat in summer, there are numerous ways that this can be alleviated by forward thinking construction. One possibility is to erect lightweight asbestos sheets above the roof to shield it from the direct sun. Flat roof insulation is another potential method of keeping temperatures down, but your roofing contractor will be able to recommend the method best suited to you.

Although in most cases a flat roof is very susceptible to weight, which can easily cause cracks or punctures, a concrete flat roof can literally be used as an extension of the living space below. Roof gardens, recreation areas, and even additional living space are all possible uses for the extra space that a flat roof can provide. Bear in mind that any ideas you have for using this space should be considered before flat roof construction starts, in order that the correct factors are taken into account.
