As the world becomes increasingly industrialized, it is important to find ways to conserve our natural resources. One way to do this is to collect rainwater from an asphalt roof. While this may sound difficult, it is actually quite simple. Here are six steps to get you started:

  1. Firstly, you will need to purchase a rain barrel. Make sure that the barrel is big enough to hold the amount of water you want to collect.
  2. Place the rain barrel underneath your downspout. This will ensure that the water flows directly into the barrel.
  3. Once the rain barrel is in place, cover it with a mesh screen. This will keep out leaves and other debris.
  4. When it rains, the water will flow into the rain barrel through the screen. Be sure to empty the barrel regularly so that it does not overflow.
  5. You can use the collected rainwater for watering plants or washing your car.
  6. Finally, remember to clean your rain barrel on a regular basis so that it does not become a breeding ground for mosquitoes or other pests.

By following these simple steps, you can help conserve our most precious resource – water!

How Much Rain Can I Collect?

One of the most important things to know about rainwater collection is how much rain you can actually collect. This depends on a number of factors, including the size of your catchment area, the intensity of the rainfall, and the amount of storage you have available.

To get a rough idea, think about an inch of rainfall. One inch of rainfall on a catchment area of 1,000 square feet will yield approximately 623 gallons of water.

If you live in an area with average rainfall and have a standard-sized storage tank, that's enough water to last your family for three days! Of course, you can always increase your storage capacity or catchment area to collect even more water.

What Are Some of the Disadvantages of Collecting Rainwater From an Asphalt Roof? 

While there are many benefits to collecting rainwater from an asphalt roof, there are also a few potential disadvantages.

One of the biggest concerns is that asphalt roofs can contain harmful chemicals, such as heavy metals, which can leach into the water.

In addition, asphalt roofs and other roof can be a source of bacteria, mold, and other contaminants. If these contaminants are present in the water, they can potentially cause health problems if ingested.

Another potential downside to collecting rainwater from an asphalt roof is that it can be difficult to remove all of the sediment and debris from the water. This sediment can clog gutters and downspouts, and it can also reduce the efficiency of rain barrels and other storage containers.

Finally, wet asphalt can be slippery, making it important to take precautions when collecting rainwater from an asphalt roof.

How to Prevent Danger in Collecting Rainwater From Asphalt Roofs?

There are a few things you can do to minimize the dangers.

  1. First, make sure that your gutters and downspouts are clean and free of debris. This will help ensure that the water flows smoothly off the roof and into your storage container.
  2. Second, check your storage container regularly for leaks or cracks. Any leaks should be fixed promptly to prevent contamination of the rainwater.
  3. Don't drink the rainwater. It can be contaminated with pollutants from the atmosphere, making it unsafe to drink. Instead, collect rainwater in a rain barrel and use that to water plants, clean the backyard, and wash cars. Not only will you save water, but you'll also be helping to protect the environment. 
  4. Finally, be sure to label your storage container clearly so that anyone who uses it knows that it contains rainwater.

By taking these simple precautions, you can safely collect rainwater from an asphalt roof.
