A mossy gutter is a common thing in the Pacific Northwest. All that moss needs to grow is a little bit of dirt, a steady supply of moisture, and few well placed spores. The gutter is almost an ideal home if you were to ask the moss.
But nobody cares what the moss thinks, because as far as your home is concerned, a mossy gutter is dangerous business. Moss in the gutters can do more than impede the flow of water and debris. It will actually retain a large portion of that rainwater. This adds extra stress to the gutter by packing on additional weight in the water-logged sections and increases the risk of overflowing on consistently rainy days.
Gutter Guards Help
Having a properly installed gutter guard can really cut down on the amount of moss that collects over a single season. Our favorite brand of Alu-Rex gutter guards are terrific for this part of the world, and they work with almost every existing aluminum gutter out there.
Using gutter guards will not guarantee you a 100% moss free existence, but it will absolutely save you more than a few trips up the ladder every season.
Take Your Time
If you decide to take it upon yourself to clean out moss from a gutter system, be sure to take your time. Moss has a root system that is very persistent. Even the smallest leavings can grow back to a sizeable problem in a few short weeks.
If the weather is good, take the time to enjoy the moment as well. Cleaning out gutters may not be the most luxurious work, but the view is usually quite nice.
