Got a Roof Leak? Here is what you need to know

A roof defends your greatest assets from our changing and often extreme weather conditions.  If roof leaks find their way to your property the water will penetrate any porous materials within.  Over a relatively short period of time, small roof leaks can lead to big expensive problems such as mould, rotted framing, electrical problems, damaged ceilings and walls, destroyed insulation, ruined contents and major structural damage; leaks should be rectified immediately in order to prevent damage.

Detecting a roof leak

Detecting roof leaks is difficult because water can travel a lengthy distance before finding an entry point in one place, dripping into another and eventually soaking into the ceiling and walls.  However, you need to know what to look for in order to identify potential issues and have them resolved as soon as possible before they become larger and more costly issues.

What causes a roof leak?

Themost common causes of roof leaks include:

Improperly installed or damaged flashing

If the flashing installed around chimneys, windows, skylights or vent pipes crack or break, rainwater and moisture will easily access your property.

Damaged or missing tiles

Tiles can become damaged or blown off in strong storms.  While missing tiles are easily identified, seeing a damaged tile is not and a storm damage inspection should be carried out.

Damaged or improperly installed skylights

Damaged or improperly installed skylights can allow water to penetrate into the property.

Blocked gutters

When gutters become blocked with leaves, water is unable to drain properly and will therefore pool in an area of the roof.  This may then cause rust holes and water will eventually find its’ way inside.

Improperly sealed valleys

If the valleys (area where two roof planes come together) aren’t sealed together properly, rainwater will get through as it runs down the roof.  This can also happen when fasteners have rusted or been blown off in strong winds.

Incorrect Roofing Material

Roofing materials are specifically designed for certain roof types and certain areas and climates.  If your roof was constructed with the incorrect and improperly fitted materials, leaks will occur.
