Gutter Problems That Can Cause Water Damage Around Your Home

Gutters and downpipes are designed to move roof water away from the building. When they are blocked, damaged or poorly connected, large amounts of rainwater can overflow into places that were never intended to handle it.

For more detail on the service itself, see our roofing and guttering page.

Overflowing gutters

Leaves and debris can restrict water flow, but overflow can also occur when the gutter or outlet cannot move water away effectively.

Leaking joints or damaged sections

Water dripping from joins, corners or holes can stain walls and concentrate water near the base of the building.

Downpipe problems

A damaged, disconnected or blocked downpipe can cause gutters to back up or discharge water beside the house.

Poor gutter fall

Gutters need suitable fall toward outlets. Standing water between rain events can be a sign that sections are holding water.

Problems at roof valleys and flashings

Some roof leaks are related to the way water is directed into gutters rather than the gutter itself. Valleys and flashings should be considered when leak patterns appear near roof junctions.

Ground drainage still matters

Even well-functioning gutters can create problems if downpipes discharge into blocked or inadequate stormwater drainage.

Treat roof water as one system

Gutters, downpipes, flashings and stormwater connections all work together. Fixing only the visible overflow may not solve the underlying drainage issue.

Roof Plumbing and Drainage: Gutters, Downpipes, Flashings and Box Gutters Explained

Roof plumbing is the system that collects and directs rainwater from the roof. Gutters are only one part of it. Downpipes, flashings, valleys, box gutters and stormwater connections all need to work together to keep water moving in the intended direction.

For more detail on the service itself, see our roof plumbing page.

Gutters

Gutters collect runoff along roof edges and direct it toward outlets and downpipes. Their size, condition and fall all affect performance.

Downpipes

Downpipes move water from the gutter to the stormwater system or approved discharge point. Restrictions or poor connections can cause roof drainage to back up.

Roof flashings

Flashings help manage water around penetrations, junctions and changes in roof geometry. Damaged or incorrectly detailed flashings can allow water into the building.

Box gutters

Box gutters sit within or between sections of a roof rather than along an exposed edge. Because overflow can affect the building quickly, their drainage and maintenance are especially important.

Roof valleys

Valleys concentrate water from multiple roof planes. Problems can occur if debris, damage or poor drainage restricts the flow.

Stormwater connection

Roof drainage does not end at the downpipe. The underground stormwater system also needs to carry the collected water away.

Look at the complete water path

When diagnosing a roof water problem, follow the path from roof surface to gutter, downpipe and stormwater outlet rather than looking at one component in isolation.
