What I Know About Dry-Rot and Mold

When you look at the result of dry-rot on wood you see that the wood has lost it's hardness and will literally allow you to put your finger through it depending on the stage it is in. Dry-rot has discoloration  like mold but it appears less powdery and less blackened. Mold is more of a slimy black area with a blooming spore type appearance. These are again my own obsevations and in no way a difinative explanation as to these two fungi. For more information on mold check out the EPA website at http://www.epa.gov/mold/moldresources.html or https://www.envirosafetyproducts.com/black-mold.html. I have experienced roof leaks enough to know that a roof leak that has been neglected and is being constantly fed with moisture can lead to mold issues but the chances are much less that will happen with a short duration. The same goes for dry-rot as it takes a constant  moisture source that doesn't have a chance to dry out. I have seen exposed boards lacking paint that have been rained on for years and the wood is still in good shape probably because the wood dried out soon after. Wood has it's own built in pitch that repells water naturally. That pitch can over time evaporate by the sun and become able to absorb more water that will take longer in drying out and that creates a fertile bed for fungus growth. This is why proper maintenance on your home will save you thousands of dollars in these kinds of repairs. Don't let your roof leak continue to feed moisture into the structure of your home. With a quick response to water issues you will save in the long term as things will only get worse.
