What causes your wood gutters to rot? First you need moisture. Of course gutters are supposed to get wet. Their main purpose is to carry water to a downspout and move the water away from your house. Ironically, the main reason for their existence is what helps accelerate their decay.

Rotting Wood Gutter

Once the moisture content and ambient temperatures are high enough wood decay spores that have settled on the wood gutter will begin to germinate into fungus. The fungus grows by consuming the wood fibers of your gutters causing the wood to become soft. Once the fungus has taken hold it can spread very rapidly if the conditions remain favorable – wet and warm. The result is failing wood gutters. The fungus is hardy and will survive the New England winters and go on to thrive in the spring and summer months.

Rot is a living organism and if left unchecked it may spread to other parts of your house. It’s common for us to remove a rotted gutter only to find that the fascia board behind the gutter is also rotted and in need of repair/replacement. In extreme cases we have seen the rot spread to the rafter tails, soffit, and rake boards. This may result in very costly repairs. If your wood gutters are showing signs of rot it’s best to have them replaced before other parts of your house are impacted.

Common Types of Rot Found On Wood Gutters

Brown-Rot Fungi actively decays wood. It is made apparent by the appearance of brown cube shaped splits (cubical fracturing) in the wood. In advanced cases of Brown Rot the wood will become powdery and will crumble. Brown Rot is common in the wood gutters made from Douglas fir, cedar and redwood.

White-Rot Fungi also actively decays wood. The wood takes on a whitish appearance and becomes soft, spongy, or stringy. White-Rot is more prevalent in hard woods.

Dry-Rot is not a fungi. What is referred to as dry rot is actually brown rot in a dry crumbly condition. It is a bit of a misnomer where there was once rot but the key element of moisture has been removed. Thus, leaving behind dry but damaged wood.
