How to Install a Roof Drain How to Install a Roof Drain
Over time a flat roof can collect too much water which will cause it to flood, to prevent this you will want to install a roof drain. Installing a roof drain isn't that difficult as long as you have the right tools and materials available to you.
Installing a roof drain is something that many people can do safely. If your roof already has lots of pooled water then you will need to use a hose pipe to syphon the water away from the roof before fitting the drains.
Step 1 - Siting your Roof Drain
If you need to siphon the water off your roof first then you can fill the hosepipe with water before submerging it in the standing water and lowering from the roof. This will cause the water to flow down off the roof.
Whenever you are installing a roof drain, the first thing that you will need to do is think about where to place it. You can place it pretty much anywhere you like in the roof. However to work the best, it should be in the lowest point of the roof. It is also normally located around the outside edge of the roof to make run offs easier. When locating your roof drain give some thought to how well it will work and how easy it will be to use.
Step 2 - Removing Bricks
Next you will need to remove bricks from the location where you are siting the roof drain so that the water can run off correctly. Make sure that you remove as small a hole as possible so that you're not damaging the integrity of your building, but at the same time you're allowing the water to escape easily.
Step 3 - Fitting Down Spouts
It's never a good idea to allow water to run down the outside of your house because this will allow lots of water to come into contact with the surface of your wall. This can cause problems because the water will gradually seep into your house. Instead you must use downspouts and gutters to redirect the water away from your house.
Step 4 - Gutters
The gutters need to be carefully put into the drains, or soak-aways, so that the water can be absorbed without causing any damage to the foundations or your property.
Step 5 - Testing the Roof Drains
Next you will need to test the roof drains by using your hosepipe. Drench the area of your roof to ensure that all the water is drained away from the roofs surface without it settling or pooling anywhere. Any pooled water could potentially weaken your roof and cause serious structural damage.
