My Dad and husband have a disagreement on rotting wood. If wood is
rotted on a 1ft. square portion of the roof, will it continue to rot,
even after the leak has stopped, and a metal roof is installed?
There is also dry rot. Rot is caused by an organism or plant that eats
wood - celulose, household bleach kills molds, spores, by removing
oxygen. So if the water is stopped kill whats there with bleach, so both
may be right to an extent, spray from both sides.
dry rot is something of a misnomer. the moisture content of the wood
needs to be elevated for the fungus to survive (something like 20% mc).
the moisture content of wood framing protected from rain will depend
on the climate, but unless you live in a rain forest, it is well below
20. on a roof where the sun beats on it i bet it's below 10%.
