Anyone who has suffered a leaking roof knows just how important the crown of the house actually is. Between constantly worrying about the weather, the buckets and the towels, it is a continuous problem that only gets worse until it is properly resolved.
Our roof is the most important feature of our house, serving to keep the rain, snow and sun outside. A small leak therefore can quickly grow into a bigger problem, and if left unrepaired can cause some serious structural damage over time.
To help combat this we have compiled a list of the most common causes of a roof leak to help you identify the source of your problem.
First, however, it is important to make sure that the leak you are experiencing is actually coming from the roof. Any number of things can cause water to drip through your ceiling from condensation building up from poorly ventilated and humid spaces to leaks from improperly sealed terraces or bathrooms. Try and find the route that the water is taking and ensure that it is coming from the roof, rather than a different source.
If you find that it is definitely coming from the top of your house, here are the 5 most common causes of a leaking roof:
Age is perhaps one of the most common causes of a roof leak. People often forget their roof entirely and leave it neglected for long periods of time without checkups or minor repairs. Like anything roofing material experiences deterioration with age, caused by wind, erosion and heat from the sun, melting the tar from shingles, creating cracks and turning important parts of the roof brittle.
Roof vents and chimneys
Roof vents which help bring air into the house or chimneys in older properties are some of the most common culprits of roof leaks. The material sealing the base of the structures to the roof can crack or misalign and allow water to seep through.
The gutter serves an important function in helping funnel water neatly away from the house, however it is also prone to cracking or becoming blocked by debris. Sometimes a gutter is also improperly placed and cascades water onto a lower roof which can cause oversaturation after a heavy rain.
Tiles or shingles
A roof that is often frequented by contractors, or one that is heavily exposed to weather that it is not properly built to withstand can cause tiles or shingles to become damaged or fall off entirely. Seeing different colours on your roof or tiles in your garden are visible signs that you might have a serious issue.
Roof junctions, or the areas where two section of your roof meet, usually experience heavy flows of water during rain. Flashing is a metal seal that normally runs along this junction and helps to direct water safely to your gutters. If this material is broken or if the joins between it and the roof are becoming deteriorated it might be allowing water to seep through.
