Flat roofs are a common type of roof. They have their advantages, and plenty of people use a flat roof as an extension of their living space. After all, a flat roof is somewhere you can create a roof garden or outdoor entertainment area. Flat roofs are also cheaper than other designs, but the downside of that is that they don’t last as long. You will need to replace your flat roof after 15-20 years, so it is sensible to be aware of what potential issues look like. Read on for a guide.

Internal Leaks

Leaks are a sure sign that a flat roof needs replacing. If water is leaking into the room below, you have an issue. It might not even be an obvious leak, such as water puddling on the floor below. Mold growing on the ceiling is an indication of water getting in somewhere. If you do spot any leaks, look online for roofers St Louis MO. You might be lucky, and the leak is small enough to repair.

Pooling Water on the Roof

One of the biggest issues with flat roofs is that over time, water starts pooling in places. Unlike a pitched roof, water can’t drain away. The right installation should prevent water pooling from becoming a problem, but if you notice significant pools of water on your flat roof, have it checked out. If water is allowed to remain for a long time, it will damage the material and could eventually seep into the underlying timber.

Moss and Algae

Green stuff growing on a flat roof might look pretty, but it’s a sign your roof needs attention. Moss and algae can’t grow without water, so if they are blooming happily up there, water is present. Pools of water are bad, as already mentioned. Look out for unwanted greenery on your flat roof and if you spot it, call an expert to check the condition of the roof.

Bubbles in the Roof Material

Flat roofs shouldn’t have bubbles and raised areas. The asphalt material used is supposed to lie flat. Obvious bubbles mean the adhesive used has failed or the material wasn’t properly glued down. Either way, it’s a disaster waiting to happen. If left untreated, bubbles in a flat roof will eventually crack and you’ll end up with a leak.

Cracks and Splits

If you spot cracks and splits in your flat roof, these need fixing too. If left alone, water will find a way in and seep into the underlying ply or chipboard. Wet wood rots and loses its strength. The last thing you need is a soggy roof on the verge of collapse.

Damaged Flashing

Flashing forms a seal along the edge of a flat roof. If there are gaps between the flashing and the edge of the roof, water will get in and cause issues.

Check a flat roof at least once a year, particularly toward the end of its natural life.
