A gutter leak is something important to fix right away. It’s a really simple and easy thing for us to fix and a moderately easy thing for most homeowners to fix. But not fixing it, promptly, can cause a lot of damage to your home.
A leaky gutter can cause water to drip down the side of the house or cause it to at least leak out where the leak is instead of at the downspout. If water from a leaky gutter slips down the side of your house it will cause damage to your soffit and roof. It may cause damage to your wall as well.
A leaky gutter that prevents some, most or all of the water to flow out of the gutter at a point besides the downspout will splash on the ground below the leak. every drop that lands on the ground washes away a little dirt and splashes , some of that splash hits the wall. Consider there will be tens of thousands of drop in the average daily pop up shower we get here in the Naples Florida area, that’s a lots dirt washed away from your landscaping. Whats usually moire important is the amount of water that splashes up on the wall.
Some walls don’t have siding, instead they stucco or concrete. Some walls have wood siding or even worse, synthetic wood siding (which acts like a sponge when it comes to moisture). The prolonged exposure to moisture will cause wood to rot, literally making holes in your walls, large ones too). With synthetic wood this happens a lot faster. Prolonged exposure to moisten also damages stucco and to a lesser, but significant, extent, concrete. Mold growth can also occur on all surfaces that are exposed to this prolonged moisture.
