Because gutters are typically out of the range of sight, it can be tricky to spot a problem, unless you can clearly see a hole or crack. If you’ve spotted signs of water ingress inside the house, damp patches on ceilings or around the windows, this is a big flag, and the leak may have been there for some time.
You may be able to tell if you watch the gutters and drainpipes during a shower of rain. Look to see if you can see free-flowing water out of the exit points and keep an eye on the gutters for signs of overflow.
Gutters can become clogged and lead to damage quickly, so if you notice a problem, it is important to tackle it as soon as you can.
