Three Ways to Know if Your Roof Has Dry Rot

Dry rot is a common problem for homeowners. Dry rot is a bit of a misnomer, for dry rot to occur the wood needs to be wetter than it should be. Wood needs to be wetter than it normally is for dry rot to start and for the fungus in dry rot to grow.


When this fungus begins to grow it weakens the wood. When this wood is used to hold up your roof, it causes structural issues. This will affect the integrity of your roof and it will be less likely to withstand the excess weight and the elements. Knowing how to find out if you have dry rot in your roof’s structure is important to prevent further roofing problems.

When checking the foundation of your roof, one of the first parts of the wood you’ll want to check the color of the wood. When wood has been affected by water, it will become darker and this continues as the fungus grows. If you are checking your roof over time, if the discoloration spreads that is a sign that your wood has been affected by dry rot.


Places that are in contact with water or moisture should be the first places to check. Areas next to pipes, vents, and windows are the best places for moisture to get in.

Splits and Cracking

Splits and cracks in wood are one of the first signs that the integrity of the wood is at risk. Dry rot eats away at wood and makes it weaker. When wood gets weaker it is more susceptible to collapsing in some way. Excess weight or even the wood weakening will make it easier for the roof to collapse.


If there are no splits or cracks in the wood, but you still suspect dry rot you can run a screwdriver across the wood. If the wood flakes off that also indicate that the wood is being affected by dry rot.

Damp Drywall

It is not necessary to go into the attic to check for dry rot. If you see damp drywalls coming from the attic then that is typically a sign of dry rot developing. Even if there is no dry rot, damp drywalls are not good signs of roof or home health. Damp walls show that there is moisture in the house that is affecting the rest of the house.


Moisture and water does not always lead to dry rot, but it always contributes to problems in your roof or house in many ways.
