6 Common Reasons why your Flat Roof is Leaking.

leaky flat roof

How often do you think about your flat roof? Can you remember the last time you inspected it or checked the gutters or the drains? Have you noticed damp patches, flaking paint or stains on the ceiling?

Here in the UK rainfall has increased in intensity over the last several years. With some regions experiencing one month worth of rain in a single day.Now we have a growing amount of flat roofs deteriorating due to the excess precipitation. We are now seeing a need to protect our homes or buildings with a modern roofing system such as a fibreglass roofing system designed to overcome these problems. So let’s get to what can you do yourself to hopefully prevent any leaks happening, and theses 6 common reasons why your flat roof is leaking.

 

Rips or Tears:

A rip or tear in the roofing material can go unnoticed until it’s too late. However, if it is caught early enough, it can be treated and repaired. If a leaking roof is left without a remedy, the roof substrate can become wet and rotten with decay. At this point, it is advisable to call a professional for a full roof inspection, as a decaying roof can be very unsafe to walk on.

Clogged Drains:

It’s really easy to forget about your drains, but they do an essential job. In fact, they are critical to keeping your home damp and leak free. You should clear the drains every autumn after the leaves have fallen from the trees. If you see stagnant water sitting in guttering, is never a good thing to leave sitting there. This can and will lead to blockages and pooling, which can cause sagging on the flat roof due to weight overload.

 

Sagging and Pooling:

Over a period of time, the older flat roofs begin to sag because of the lack of support. So when a flat roof begins to sag, water will collect in the low area of the sagging roof. This ponding water will not run off and it can cause deterioration of the roofing material. Normally or depending on weather conditions, it is only generally determined as a problem after 48 hours if it hasn’t drained away. A structural roofing survey is required to determine whether the joists and boarding need to be replaced.

 

Flashing:

Flashing is one of the most important parts of your roof and protects the joint between the vertical wall and the flat roof. It can be made of copper, aluminium, lead or tar. When this deteriorates water can seep into the brickwork and into your home.

 

Skylights and Vents:

Skylights or vents if incorrectly installed can be a cause of a leaking flat roof. If you have a leak coming from an area near the skylight or vent, it would be best to seek professional advice, as they may need to be refitted.

 

Inadequate Roof Slope:

Flat roofs were originally seen as a cheaper solution to pitched roofs and were only adopted in the UK after world war two. The lifetime of a flat roof built after the war has been somewhere between 10 and 35 years. Without a low slope to the roof to allow the rain to run off, the roof can deteriorate due to pooling and rapid ageing.
