While waterproofing of the other structures is of prime importance, it is equally significant to consider roof waterproofing so that an impermeable layer is formed over the roof, which will prevent water seepage,and prevent structural damage to the building. The choice of roof waterproofing materials, that suites the Indian tropical climate, is all the more essential.

The materials generally used for roof waterproofing are cement-based material, bitumen-based material, and liquid-based waterproofing membrane,also liquid membrane using polyurethanelike a Polyurea Membrane.

Some of the roof waterproofing services in India use most of the above materials for waterproofing the various structures, both commercial as well as industrial. Accordingly,the methods applied for roof waterproofing by a majority of roof waterproofing services in Indianeeds to be selected carefully, since most of the conventional methods of roof waterproofing do not work effectively under Indian weather conditions. They being ineffective are also a waste of time and money.

The thermal expansion, due to extreme heat during day time and the contraction due to sudden cooling during the cold nights, especially under extreme climates, leads to cracks in the concrete roof. Due to the inelastic, conventional roof waterproofing system, there will be cracks in them as well.

Therefore new, more elastic roof waterproofing latest products have been developed by Indian manufacturers and roof waterproofing services in India, to overcome this drawback. These are liquids which can be applied with a brush and are bitumen-based, acrylic-based, PU-based, etc; which can also be in the form of pre-formed membranes. These types of membranes are laid loosely or stuck using a blow torch.At times self-adhesive membranes are also convenient to use.

With the type of required roof waterproofing,the products having a bitumenbase, acrylicbase, or Polyurethanebased solutions and can be used depending on requirements. Each type of these products meets specific requirements in roof waterproofing. The advantage of these products and methods is that leakingroofs are not required to be broken completely. It can be repaired by deploying such products which can be coatedusing a brush.

Even thoughthe modern methods of roof waterproofing services in India are superior to the conventional methods in terms of effectiveness, less application time, easy to apply, cost-effectiveness, it is still not popular among many builders for want of awareness. There is a certain unique polyurethane waterproofing system which can be sprayed to apply. It has no joints andprovides2.5 times better insulation against extreme temperatures and also requires about one-tenth of manpower as compared to roof waterproofing using the conventional brickbat coba.
