The Most Common Causes of a Leaking Roof

As a homeowner, the very last thing you need is a leaking roof. One of the great problems of roofing is that many homeowners are simply not equipped to either understand the cause of the problem nor how to remedy the cause.

At IronHead Roofing, we have helped clients through Albany, Corvallis and beyond in the greater Oregon area, with their leaking roof. In many cases, the cause is relatively benign; something that can be fixed without too much time, cost or effort.

However, in many other cases the cause is severe – damage that has accumulated over many, many years. In these cases, a more robust approach is required which can result in a substantial roof repair operation.

That’s why we encourage homeowners to conduct a regular, basic inspection.

Value of Roof Inspections

Of course, we do not encourage more intensive inspections that carry health and safety implications. After a storm, for example, you may be able to notice damage from afar or perhaps you’ve become concerned about the effect of wind damage on your roof.

Whatever the cause, a thorough inspection is always warranted.

Even if your home hasn’t recently experienced a storm or other traumatic event, damage can still accumulate – often silently – over many years. In the same way that your body can become damaged internally without notice, so too can your roof.

Homeowners should always remain vigilant.

What are, then, the most common causes of a leaking roof? Here, we go through some of the most common examples we’ve encountered here at IronHead Roofing.

#1 Slipped tiles / slates

Have you experienced slipped tiles or slates in the past? If you have, you may notice that a pool of water can accumulate. With slipped tiles and slates, more rain can access the underlay during periods of bad weather. Over time, that water can trickle into the roof to cause substantial damage.

#2 Condensate

One of the great causes of a leaking roof, or at least the perception of one, is the presence of condensation. Insufficiently aired and ventilated will inevitably produce condensate on the underlay of the roof which, over time, can trickle down onto the ceiling. Roof spaces should always be adequately ventilated to prevent the formation of condensate.

#3 Compromised underlay

Compromised underlay is one of the most common causes of a leaking roof.

When we talk about compromised underlay, we’re talking about that part of the roof designed to pass water down the gutters. Of course, this is the function of the underlay, but it doesn’t always work in the way we’d like it to.

Over time, the effect of wind and rain and destroy and, in the end, rot the underlay. Slate or tile damage, no matter how small, can result in the passage of rain through the underlay and into the internal roof space, causing leakage.

#4 Failing Extensions

Do you have a lean-to extension? If you do, there is a significantly higher chance of experiencing a leaking roof.

And if you think about it, this makes sense. Rainwater that hits your roof falls and passes onto the lean-to extension. Pressure on the lean-to extension is doubled; first from the rainwater hitting the extension and, second, by the additional discharge from the main roof.

Over time, this can compromise the tiling and underlay and increase the risk of a leaking roof.

#5 Junctions

One of the gravest, and most common causes of a leaking roof, is damaged roof junctions.

When the flashing at the junctions of the roof is incorrectly installed, or damaged, it means that the area becomes terminally exposed. Once a sufficiently large volume of water hits the junction, it can collapse and lead to a substantial roof leakage problem.
