Roofs with little or no slope have gained a good deal of popularity due to their economic and structural feasibility.

They have evolved to become the default roof type for most tall buildings and as well as to be a requirement for creating eco-friendly urban landscapes. Having a flat roof atop your building can offer you many benefits such as the ability to convert it in to a roof top garden or to make your building more energy efficient by converting it in to a solar roof.

The longevity of this type of roofs is determined by the roofing materials, the weather conditions and proper maintenance. Concrete roofs atop tall buildings generally have slightly sloped concrete roofs. Allowing rain water to drain properly is rather important as pooling water can lead to structural damage and in large quantities and longer time frames, lead to sagging. A suitable method of water proofing is essential for the long life of the roofing materials as well as the interior of the building.

A quality flat roofing systems from a reputed flat roofing installer usually comes with a waterproofing method included in the full package.

The water drainage system is also very importance to the condition of the roof. In most situations it is necessary to install automatic siphons which will suck in pooled water at regulated intervals to prevent sagging and seepages and in the case of cold climate, freezing and adding to the dead load. But, this should only apply to roofs made out of fragile materials.

In the case of concrete roofs or roofs made of stronger, sturdier materials, it is necessary to install roof drains.

Regardless to what materials the roof is constructed out of, it is necessary to check up on the condition of the roof occasionally and especially after a rainstorm or other extreme weather occurrence. Roof drains and gutters should be regularly inspected and cleaned to make sure that they don’t clog and lead to water retention on the surface of the roof.

In addition to all this, the flashing which seals the seam between the roof and the wall plates should always be kept intact. If the flashing is not properly fitted, that would eventually lead to water damage on the walls. The main thing to keep in mind is to make sure that the proper maintenance of the roof can add years to its lifetime and also add to the overall quality of the building as well.
