Bitumen WaterproofingHailed as being a perfect waterproofing material for roofs because of its ability to move. It is considered to be not too rigid as well as being impervious to water.
In its raw form Bitumen resembles tar. When applied it is first heated and then brushed onto the surface it is protecting. However it may not be the best option for extremely cold climates as these weather fluctuations may cause cracks.
It is not water soluble, and it is not biodegradable. Bitumen roof products are available in different top surfaces however which can help blend into the landscape, it offers a long lifespan, reflect sun rays. However this is a roof waterproofing that takes the place of tiles or shingles, and is not applied as an under layer. Perhaps it is an option best used on flat roofs where it is not easily seen.
The three waterproofing ideas mentioned here are perhaps the most common methods for waterproofing a roof, but they are by no means the only ones. Technology today is advancing each year and with it comes newer and newer innovations aimed at saving time and cost, adding value and increases longevity.
For some of us in South Africa who have to contend with a lot of rain one of the easiest methods of preventing water seepage is to have a slanting roof, but this on its own does not guarantee waterproofing. We need and extra layer between the roof, the elements and us. Those who opt for building a flat roof need above average waterproofing as water tends to build up which can lead to water logging and seepage over time.
Waterproofing a roof is a very big thing, if not done properly the results can be disastrous, even leading to a compromise of the very structure of not only the roof but of the entire building. Water can creep into concrete cracks and can cause iron to rust and weaken. Rusted iron expands which causes the concrete to crack even further and eventually as the iron becomes nothing more than powder, the structure loses its strength. All this because your roof wasnít waterproofed correctly!
If you are one of the unfortunate few who are experiencing water leakage, donít hesitate in calling in the professionals. Many different options are available today which will put an end to any further leakage before it becomes the nightmare of having to remove the entire roof and replacing it. Who knows, it may be something that can be simply fixed by means of painting a waterproofing on the areas that are affected.
