Most common causes of roof leaks

Posted on by Protech Roofing Team

No one wants to be shivering on top of the house in the pouring rain, in an attempt to patch up their roof; or scouring the house for a big container to catch the leak, for that matter. This month with Protech Roofing, we aim to keep you in the know with the common causes of roof leaks, so you can get to the root of the problem or avoid a leak altogether.

Failure of underlay:

roof tiles and slate are utilised to keep out rainwater, however, with the addition of strong winds, rain can occasionally seep through the gaps under the tiles. This is why underlay is fixed underneath the tiles, as it’s job is to transport water to the guttering. As you can imagine, this process can eventually cause general wear and tear. When failure does occur this leads to leakage, so it’s important you maintain your underlay with regular checks, to prevent this from happening.

Slipped tiles or slates:

tiles or slate that has moved results in a buildup of rainwater which can cause a destructive leak. It is important for you to get any slipped tiles or slates looked at in good time. This is something that can’t be avoided especially if there’s a belt of bad weather, so if you do notice damage after a storm or heavy rain, it’s in your interest to get someone to relay your tiles. This will save yourself the hassle of sorting out a large leak in the long run.

Damaged roof junctions:

incorrect installation can cause leaks, and unnecessary wear and tear to the flashing. Unfortunately a small issue can rapidly get out of hand due to the inconsistent changes in the weather. If you can visibly see an issue from the outside or spot damp in the corners, seek help from an expert who will sort out this issue.

Lean-to extensions:

if you have a lean-to extension, this increases the chances of a leak. With the rainfall already being transported off the upper roof, this will fall on the lean-to extension that’s already carrying it’s own rainwater. The increased pressure can potentially cause a leak.

Condensation:

a poorly ventilated roof can be a non-direct cause, but can appear to look like there’s an issue with the roof itself. This is simply droplets accumulating and dropping, creating patches around the ceiling. This can be salvaged with simple roof vents.

Debris:

a build up of leaves and twigs can block the guttering, trapping the rainwater on its journey to the drain; the water will overflow and can cause a leak. An easy way to keep this maintained is to trim back any trees close to your guttering.

Punctures:

if you’ve had any rooftop installations, such as TV antenna removals, the roof should be checked over to make sure there aren’t any holes after the work has been done. If there are, they need to be covered.
