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? Thank you, Lorraine
no. dry it out and the rot will stop.
The other question would be "Is there enough solid wood left to hold nails and keep the new shingles in place at that location?"
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.
why not replace the 1 square foot portion if a metal roof is going to be installed?
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
Chlorine bleach is bad for wood. It destroys the lignin.
Use antifreeze and borax instead to kill the mold sporeds and permanently treat the wood:
