A flat roof is designed and installed in a way that endures repeated exposure to moisture, sunlight and all other weather systems.

However, like everything, there is always an expiry date whether we like it or not. Depending on the type of material used and the installation method, the life span of a flat roof can vary significantly with traditional flat roof systems such as felt having the most common problems.

Here are a few tell-tale signs that you could have a leaking flat roof:

1. Pooling water

If your roof has a low spot surrounded by a dirt stained ring, then it is quite likely that you will have some pooling water. Seek advice immediately if this happens to your roof as it could be a sign that your timber structure is damaged.

2. Cracks & Blisters

If your flat roof has any cracks or blisters, they need to be dealt with as soon as possible. These are weak spots in your roof that will eventually wear and tear and allow water to seep through the flat roof’s protective covering.

3. The undercoat is exposed

If the undercoat of your flat roof is exposed, then there is no covering protecting your roof at all. Wet weather can cause significant problems if this issue is not dealt with immediately.

4. Water stains, mould or wet insulation inside your home or on exterior walls

If you have any interior damage you must call a contractor immediately. If the problem is not dealt with as soon as possible, the water could spread further around the house and cause significant structural problems.

5. Flat roof is covered in moss, algae and grass which compromises the protective roof covering

If your roof is covered in moss, algae and grass, your flat roof is a lot less effective than it could be. Ensure that you are undergoing an effective maintenance procedure for your flat roof.

If you have a leaking flat roof, you must always treat it as an emergency. Water entering your home can wreak havoc in a matter of days. If you don’t deal with the problem straight away, a leak can end up causing significant structural problems and end up being incredibly costly.

Remember that when it comes to a flat roof, the source of the leak may not be directly above the damage. The only way to determine where the flat roof has been compromised is by visually examining the roof’s surface on a dry day.

It’s also important to note that walking on a flat roof comes with its own risks – Particularly if its integrity has been compromised by a leak. In the first case, try to spot the damage using a ladder and/or binoculars, or ask a professional flat roofing contractor to take a look.

Seek professional help

If you still cant detect the source of your leaking flat roof, always seek the advice from a professional. A good flat roof contractor will always be able to find the source of the problem and quote you a competitive price for getting the work done. Even if you’re a DIY superstar, do not take any chances in fixing your flat roof without prior experience. You could do yourself and your roof more harm than good in long run!

I hope this helps!
