Overflowing guttersWe regularly talk about the importance of a proper gutter maintenance and how we should regularly clean and check our gutters for damages. But today we would like to talk about why it is so necessary to keep your gutters and downspouts clog free and fully functional.

When leafs, twigs and other debris block your system, all the rainwater that falls over your rooftop gets trapped in your gutters. “Big deal” you might say. Actually, it is. Did you know that …

  • Frozen water in a gutterA litre of water weights 1 kg or 2.2 lbs
  • The average rainfall that falls over London is approximately 23 inches or 50 mm per year
  • Just a single inch of rainwater falling over a 1,000 sq ft surface will produce more than 600 gallons or nearly 3,000 litres of water annually
  • The average Victorian house has a 1,000 sq ft of tiled roof
  • This makes an average of 70,000 litres of water that pass from your roof, trough your gutter system
  • Yes, that’s a lot
  • Experts estimate that a heavy blizzard can increase the weight of a water-filled gutter by as much as ten times!
  • If frozen, a single gutter filled with water can weigh up to 50lbs. That’s 20+ kg of ice hanging over your head, most often held to the rooftop by a plastic gutter. Is it a risk you are willing to take?

Leaking gutterSo next time after a heavy rainfall you find your gutters filled with water, consider the above facts. What can you do about it? The best thing is to clean your gutters regularly. You can also install gutter guards, but they will not solve your problem entirely. Having copper gutters might also help, since they are much more durable, but their price is a factor that drives away many.

Overall, you should know and accept that your gutters will always get clogged sooner or later. Regular cleaning and repairing is the only key to keep them fully functional at all times. If you find trouble with any of those you can always use our guttering repairs specialist to fix it.
