As you look at a home or any building, it is not easy to state objectively what part of it is the most important. Any defect in the design or construction can detract from the overall building and can even become a nuisance for the people living within it. Certainly, one element that you take for granted unless it should be defective or fail in some way is the roof. A well-designed and constructed roof will protect you from the elements of nature, especially the sun and rain. But if a roof starts to leak, as it gets older, subject to the heat of the sun on a daily basis, the annoyance is very distressing. Water leakage will quickly damage ceiling materials such as drywall, and dripping water can destroy your possessions, especially if the leak occurs when nobody is at home to develop a quick emergency solution. Roofs that are placed at a low angle or are almost flat are especially prone to problems due to the tendency for water to stay pooled and seek alternative paths through the smallest fissures and cracks. Where freezing temperatures occur, such fissures and cracks will automatically widen when freeze-thaw cycles occur.

For well over 40 years, high quality flat roofing has been available for use where flat roofs are desired. These are made using an extremely durable polymer membrane that is impervious to water. This flat roof material will typically last 40 years or longer. More than 8 million square metres of these roofs have been installed around the world in basically every climate from frigid arctic climates to scorching deserts. This type of roof is strong enough to support standing and walking. Conventional tar-based roofing materials are an obsolete technology using materials that deteriorate after a few years of weather. The cost of polymer-based flat roofing is naturally higher, over the long run; the costs probably come out being less, especially if a conventional roof has to be replaced every 10-15 years, since labour costs seldom decline. So, this is effectively an investment or a kind of life insurance for your roof.
