There are many reasons why roofs leak. There are defects in the general waterproofing treatment: structural and waterproofing layers even if the original practice is maintained, but generally also in the prefabricated hollow slab on the coil waterproofing layer, so it is still inevitable that leakage occurs at weak links such as along the gutter. A serious problem, especially with rigid waterproof roofs, is that cracks may appear in the waterproofing layer after construction is complete and water leaks. There are many reasons for cracks: climate change and solar irradiation caused by thermal expansion and contraction of the roof; warping deformation of the roof panel after the force; foundation settlement or wall bearing after sitting pulp shrinkage and other reasons caused by changes in the roof; roof panel material dry shrinkage deformation, etc.
Of course some people like to plant flowers, plants, or vegetables on the roof and so on. There are too many water sources for roof gardens: watering water for various plants, pools, fountains and other water bodies are also used extremely frequently, making the roof an additional source of water that produces leaks. The drainage system on the roof of a building does not take into account the leakage of water from plants and the drainage of water bodies required for the construction of a roof garden, especially when the watering water and pool sewage contain plant roots and leaves and sediment and other debris, which can block the drainage opening and pipes and cause water to accumulate and leak on the roof.

Roof construction destroys the original waterproofing: roof gardens built on roofs can leak, and a number of landscaping works on the waterproofing layer of the roof, which is more prone to leaks, make it more likely that the waterproofing layer of the roof will be damaged and lead to leaks. Even if holes are not drilled and perforated or iron fixings buried, if not carried out with care, the waterproofing and drainage structure of the roof can still be damaged, resulting in roof leaks. Sometimes planting can also damage the waterproofing, for example, the shovel used to fill in the soil can damage the waterproofing.
If the roof has a large area of leakage or multiple leaks, first by professionals in roof guttering malaysia to check whether there are cracks, first deal with the leaky cracks, in the entire roof on the waterproofing membrane, if you want to strengthen the waterproofing effect, you can also lay on the thermal insulation board, can achieve the dual effect of protecting the waterproof layer and thermal insulation. For roofs where insulation boards are not used, consider using wire mesh mix. In the case of cracks and water seepage on the walls, the professional construction team will normally use hanging baskets and the maintenance staff will work on the external walls.
