Subject: leak fixed...still rotting?
Date: Mon, 27 Mar 2000
Dear Dr. Rot,
When roof joists or wall studs suffer some degree of rotting due to roof leaks, and the source of the water is stopped...will the wood continue to rot even after it dries out?
The damage is not so much as to need to replace the wood....just don't want to worry about what still may be happening that I cannot see.
thanks for your help,
Rot fungi require a wood moisture level in the 20-30% range to propagate and
thrive. Usually when the leaking is stopped, the moisture levels drop below
However, the reproductive spores of the fungi are still in the wood, and if
the moisture levels rise again -- from whatever cause -- the rot will resume.
For this reason we encourage people to treat the wood (if it's accessible)
with our CPES (Clear Penetrating Epoxy Sealer). This pretty much ends the
fungi problem and makes the wood incapable of absorbing enough moisture to
reach dangerous levels.
