Solving Flat Roof Problems

Hi, I’m John Barnett, owner of Broadstairs Roofing. In this article and video, I show you the top 6 signs that your flat roof might have a problem, the top causes of problems with flat roofs and what to do about them.

If your home has a flat roof, the chances are there could be hidden problems as well as some obvious signs that your flat roof needs attention.  If left or ignored, these problems can worsen and cause further damage to your property.

So what are the top 6 signs that my flat roof might have a problem?

1# Signs of damp on interior ceilings or walls

2# Blistering of the membrane covering material

3# Water Pooling or blocked rainwater outlets

4# Visible signs of debris including leaves and vegetation growth

5# Cracking of seams/joints

6# Damaged or deteriorated flashing causing water to go behind the felt

If your flat roof shows any of these signs, it’s a signal that it’s showing early signs of deterioration and you should act now before things get much worse.

What are the top 4 causes of problems with Flat Roofs?

#1 Leaks
A leak can start small but the water ingress will cause problems and worsen over time. As the leak worsens, the damage becomes a problem affecting not just the roof but the adjoining seams and the building’s interior walls.

#2 Weather damage
Over time, our drastic weather conditions in the UK, particularly along the coastline, can seriously damage flat roofs and if left untreated become increasingly troublesome, such as water seeping through the roof causing damp and deterioration of interior ceilings and walls.

#3 Poor fitting
A flat roof should actually have a slight gradient to allow rainwater to run off and have a decking of marine or WBP plywood. If your flat roof hasn’t been fitted properly, it can lead to a variety of problems which occur over time such as water ingress, condensation, water pooling, cracking and thermal movement.

#4 Lifespan
A flat roof typically has a lifespan of 10-20 years depending on the material. Over time, the roof will deteriorate and will need completely replacing.

Acting now can save you money in the long term.

If left, a leaking or damaged flat roof will deteriorate quickly and become costly to repair or your flat roof could need completely replacing. Here’s what you can do about the problem right now:

  • Have your flat roof inspected by a Qualified Roofer with experience in flat roofing
  • Have a Survey carried out of your flat roof
  • Find out why it leaked and arrange to have the problem repaired
  • Get recommendations about what can be done for prevention in the future.
  • Invest in a new modern flat roof which will last for up to 25 years.
