Understanding to Roof Leakage Problems
A newly and properly built tiled or metal roof is water-tight and there should be no occurrence of water leakage. A properly designed and built roof will only start leaking after years of wear and tear. Singapore experiences hot weather all year round, it is especially hot during midday when the sun is scorching. But when it is past midnight, temperature starts to drop by 4-5 degrees Celsius. The problem is this, your roof tiles and metal roofing sheets expand dramatically during the midday sun and contract during midnight when temperature falls. Over time, these roof tiles and metal roofing sheets get damaged and crack. When there is presence of cracks and water, water leakage will occur.
SWC Construction’s answer to this form of water leakage is to carry out application of waterproofing membrane onto the existing roof. This method saves a significant sum of money as compared to removal and installation of a new roof.
Moreover, SWC Construction’s green roof system is proven to reduce roof temperatures by 60% and it keeps your roof temperature constant, varying not more than 2 degrees Celsius throughout the day. As a result, your roof is being protected from thermal expansion and contraction which lead to cracks. Moreover, our green roof system is lightweight, approximately half the weight of conventional systems, and soil-less. This makes our green roof very feasible and suitable to be installed onto your existing roof without the need to make any structural changes.
