A brief history of coating practices in the past would serve as an eye opener to the need and advancement that preventing flat roof leaks San Antonio has done. It is not as though there were no leaking roofs in the past and the use of poly vinyl coating only started about a hundred years back when the petroleum industry came about.
The use of resins to prevent flat roof leaks San Antonio
One of the first substances that came to be applied to water proofing solutions across the world is resins. The material came to give as natural a sealing function as possible and the use of the material became quite common and rampant. This was particularly in use in the colder climates where the problem of water logging of the roof structures was seen to happen.
There is the effect of stagnant water on roofs that drew the attention of builders of tenements from the very early stages of town planning. The ready source of resins that could prevent the worst types of water logging was thus a heaven sent opportunity to a lot of people. The resins had an additional property that it could be impregnated into roof material at little effort.
The innovative use of oily substances
From time immemorial, the use of oil impregnated cloth and paper was seen to be effective against water seepage. This was in use in countries like Japan in the old days to prevent water seepage. The method was seen to be effective and yet affordable solution that a fair part of the population took to it.
There were some oils that are had from the processing of sea products that are particularly effective in the prevention of seepage and ingress of water in living spaces. The planners of the days gone by were particularly keen on harnessing the goodness that blubber from whales and such by products afforded to people.
Tar as an effective insulation
In the very cold climates, it was common for roof tops to be completely covered in snow and at times water for a good part of the year. This made it necessary that a method needed to be devised to keep out the moisture from the insides for sometimes like six months in a year. With the development of the petroleum industry, the byproduct of the process of refining, tar was particularly use full for the purpose.
The hardy and lasting nature of the tar made it an ideal yet cheap product to use at all times and in most encountered conditions. Thus it soon became customary to finish off a roof with a coating of tar. The only drawback was the sheer weight of the substance, which made it necessary that the roof structure must be sufficiently strong enough to support the additional weight.
The later development of materials that specifically were useful in the construction industry made most of the above methods and applications redundant.
