How to locate a roof leak

Roof leaks can differ in size from a small, barely noticeable trickle, to a business halting, costly deluge. Roofs leak for a number of different reasons; from dislodged shingles and tiles, gaps in the joinery, small holes in the roofing caused by adverse weather conditions, acts of God or even from general wear and tear that damages your roof slowly over time.

Both domestic and industrial properties can suffer from a leaky roof. Domestic properties have the benefit of being under the watchful eye of those that live under it and therefore leaks are usually spotted quite easily. Especially as the roofs tend to be slanted, making them much more visible from the ground.

Industrial roofs, on the other hand, tend to be much larger. They may have more people underneath on a daily basis but most of these will be too preoccupied at work to take much notice of what is going on above their heads. And the major problem with industrial roofs and spotting leaks is that industrial roofs are almost always flat. Not only are these too difficult to see from ground level, they are also far above the heads of those inside. For an industrial roof to be checked, someone needs to go out on to the roof itself.

If you suspect your property’s roof is leaking then it is wise to send someone who knows what to look for to inspect. Because of the added danger of walking around on top of a large commercial structure, it is recommended that you hire a professional roof inspector or contact your roofing contractor to carry out the inspection for you.

However, there are a few things you can do to keep an eye on your roof and spot leaks that do occur, identifying them before they have time to escalate into a serious problem.

Signs of a leaky roof

Water stains are always the clearest indication that rainwater is permeating your roof. They are most prominent on wood, which makes it easy to spot in domestic properties but slightly more difficult when it comes to industrial roofs which are made up mainly of metal.

A better way to spot an industrial roof leak is via water spots. These are much easier to spot as they are noticed inside the building. You can use these water spots to judge where your leak may be originating from; hint, it is usually directly above.

Check your roof shortly after a bout of heavy rain to see if any water is leaking through. If you suspect your roof has a leak but the weather is dry you can spray the roof with a hose pipe to mimic rainfall and check for any leaks.

The location of the leak on the roof may be separate from where any evidence of the leak culminates. Water can run between the shingles before exposing itself inside the building so you may have to follow the water trail before finding where the water is getting in. Once you have located the leak, contact your roofing contractor and have the problem remedied as soon as possible. The longer a problem like this is left, the more damage it can do.
