Potential Downpipe Issues to Look Out For

Posted on

Rain is one of the most harmful predators of a home. Water can rot structural timber beams and interior walls, resulting in significant damage. That's why the guttering system and downpipes are built to properly drain rainfall. Rain runs down the roof tiles or metal sheets into the gutters. It then runs into the downpipes, where it's carried to the ground and away from the structure. Downpipes might have issues from time to time. Though your roofer can resolve these difficulties, it's helpful to be aware of the possibilities.


Downpipes can become clogged as a result of leaves and debris carried by the rain. If the downpipes jam, the rain will have no choice except to overflow the gutters as a means of escape. It might spill into the roof cavity or flow down the outside walls, resulting in moisture and mould. Leaf guards over the gutters and around the tops of the downpipes can help avoid this. The downpipes can be unblocked by a contractor to free up the system.

Drainage Issues

Rain can exit downpipes in a variety of ways. You might notice a drain underneath that connects to the stormwater system. Downpipes can also curve away from your house and carry rainwater to a garden area, where it can seep into the ground. They don't always dispose of rainwater properly. The water may, for example, be discharged too near to the house. It can seep into the earth near the foundation, causing the structure to become unstable. If your home is built on a slope, released water should flow away from it rather than towards it.

Downpipe Capacity

The downpipes must be able to handle the amount of rain that they receive. This will be determined by the roof's size and pitch, as well as the local climate. Roofs with larger areas gather more rainfall than those with smaller surfaces. Plus, roof pitches that are steeper transport water to the gutters faster than those that are softly sloping. Often, a structure will require more than one downpipe. They're frequently needed near a roof valley that gathers water from two different roof pitches. In rare situations, the downpipes that were initially placed can't transport the water they receive.

Broken Piping

Some rainwater downpipes are made up of sections that connect with clasps or screws. These attachments can wear away, and parts of the piping fall apart. The rain will then flow out the bottom and along the external walls. If the downpipes don't reach the ground, you can easily notice this problem. You may also see screws scattered about.

Contact a roofer if you need help with your downpipes.
