Water shedding is a very broad term that can refer to two main objects: water-shedding roofs and watersheds.
Although water is the very basis of life, too much water at the wrong place is a recipe for disaster. Rains, torrents, and tropical storms are some of the weather hazards that could unleash a huge volume of water on your roof, and if the roof of the house is not prepared for this influx of water, the internal structure could be severely damaged.
Water-shedding roofs are one of the main solutions against surging rainfalls. With these roofs, your home will be much safer from these disasters. But what is a water-shedding roof and how does it help to protect your home? And how do watersheds, a completely different but somehow related term, are related to them? This article will provide you with the information you need.
What is water-shedding with regards to watersheds?
Water shedding can also refer to watersheds, which are geographic regions that have some similarities with water-shedding roofs. In watersheds, excess water is drained from the land by a single river or a stream. These areas tend to have very steep slopes that facilitate fast streams of water that flow towards a larger body of water. When torrential rains fall down a watershed, or when it faces massive storms, the water will be drained much quicker than in other regions.
Watersheds are very important to the environment as well as an economy. A healthy watershed, one that involves dynamic hydrologic and geomorphologic processes, offers superb drinking water, and you can actually drink water from the rivers in these regions without fear. Healthy watersheds also improve the quality of recreational activities such as fishing and camping in the region. Finally, if you own properties within a watershed, their values might be substantially higher than in other areas.
Because of the benefits that watersheds offer to a region, watersheds must be protected at all cost. Without healthy watersheds, the quality of clean water within a region will be severely affected, and wildlife’s quality of life will plummet. One of the major threats to watersheds is forest fires, which have been increasing in intensity in recent years.
How is water shedding on a mountain similar to water-shedding roofs?
It is quite easy to see the similarities between watersheds and water-shedding roofs. Both have hydrokinetic properties, which means that both can facilitate faster water flow downstream. Both of these things are very good at preventing water puddles and ponds from forming on their surface, which can potentially be damaged by stagnant water. Thus, it can be inferred that water-shedding roofs might take inspiration from watersheds themselves.
Watersheds and water-shedding roofs are very different from one another, but they essentially share the same water-shedding principle. Watersheds help to improve the quality of clean water in a region, and water-shedding roofs will shield your roof from water damage with ease.
What is water-shedding with regards to a roof?
A water-shedding roof is also called a hydrokinetic roof by experts in the field. These roofs tend to have steep slopes that feature a ratio of more than 3:12. These steep roofs are generally used in residential buildings or buildings that have some aesthetic values such as churches, shrines, etc. Underneath their metal cladding is a water barrier membrane.
Water-shedding roofs are designed in such a way that they will allow water to run off its length with ease. Water will then be drained down a drainage system, preventing the formation of puddles on the roof of your home. Because the water drains faster than it accumulates, your roof will not be endangered by torrential rains.
Why choose a water-shedding roof?
A water-shedding roof is a very powerful tool to protect your home from rains and storms. This is because this kind of roof will drain water very quickly, and puddles could cause a lot of damage to your roof because water-shedding roofs do not tend to have a waterproof coating.
These roofs are also very resilient against powerful winds, which are also a hallmark of storms. This is due to the fact that water-shedding roofs are made from metal, which can withstand gusts of 140 miles per hour in wind speed. Metal water-shedding roofs are also highly resistant against updrafts.
Hydrokinetic roofs are also more aesthetically pleasing than hydrostatic roofs, which is the other kind of roofing design that it is often compared to. This is one of the main reasons why water-shedding roofs are very popular with residential construction projects.
Water-shedding roofs vs water-resistant roofs
Water-shedding roofs often get compared to water-resistant roofs when you talk about roof design. Both of these kinds of roofs are actually quite common, and each comes with a set of benefits and downsides that make them appropriate for different construction projects.
The biggest difference lies in how each of these two kinds of roofing designs works. Water-shedding roofs work by quickly directing water down the drain, thereby preventing water from forming puddles on your roof. These roofs will have a little water-resistant coating. Conversely, water-resistant roofs drain water more slowly than the other kind, but these roofs have a strong water-resistant coating, so they can make sure that even if the water forms puddles on the roof, it will not be able to damage the integrity of the structure itself.
In terms of design, water-shedding roofs will have steeper slopes, and water-resistant roofs will have flatter designs. This is because the water will need to be drained quickly on water-shedding roofs, and a steeper slope will help it do so with ease. On the other hand, a water-resistant roof does not need to quickly drain water, so a flatter slope will still be serviceable.
When it comes to water penetration, hydrokinetic roofs do lag behind a little bit. For example, if the house comes with chimneys or valleys, the downward flow of the water will be interrupted. In these particular areas, hydrostatic elements will be greatly valued, because if the water settles down into puddles, the roof could be damaged. Thus, these areas have to have added hydrostatic details.
Finally, with regards to which construction projects use which kind of roof, water-shedding roofs are more commonly seen in small residential projects or any building that requires a sort of aesthetic value. This is because steeper roofs tend to be more aesthetically pleasing. Flat roofs can be seen as unappealing by some, so water-resistant roofs will not be used on residential buildings but on industrial ones instead.
Water-shedding roofs are a very effective solution against both heavy rains and strong winds. They have very steep slopes that allow water to flow downstream to the drainer at a very high speed, ensuring that water will not rest stagnant on your roof. Water-shedding roofs are often compared to water-resistant roofs because they both are quite popular roofing designs. However, while water-shedding roofs try to drain water as quickly as possible, water-resistant roofs try to mitigate the damage by water-proofing the roofs themselves. Both methods work in different circumstances, so it is impossible to tell which is better than which.
