I found out that the vent on my roof that is used for the bathroom fan is leaking a bit. I’m going to take out the vent and re-install it making sure that it is well sealed. There is some mold around it on the surface of the plywood (the side that is in the addict). the house is only 4 years old and I’m told I should be able to just use some bleach and kill the mold after making sure it is sealed and I should be good to go. Just looking for other opinions/suggestions.
Bleach does NOT kill mold. You must use a biocide or anti-microbial. Supporting article: http://www.normi.org/articles/bleach-mold.php
It won’t be easy on a substance such as plywood because of it’s multiple layers into which mold spores can penetrate. However, after an application of biocide or anti-microbial and allowing time to dry, check to see if it returns. If not, I would seal with Shellac. Just brush it on. Sealers/Primers such as KILZ often contain Shellac because of it’s sealing properties and the fact that any finish including paint can be put over Shellac. If you elect to use KILZ or a similar product, make sure it has a anti-fungicide in it. If not, it can be added.
Finally GET RID OF MOLD for good, watch the free video training guide.
and...
Only non-toxic mold removal products to KILL and PREVENT MOLD from coming back... guaranteed. This saved me a lot of future mold headaches.
I have friends who work in the remodeling industry and they insist that bleach is the best form of mold-death.

bleach will kill it fastReferences :
STOP THE LEAK U STOP THE MOLD
MAKE SURE IT IS JUST STAINED AND NOT ROTTED.
IF YOU ARE GOING TO REMOVE TO REPAIR, U COULD REPLACE A SMALL SECTION OF THE DECKING WHILE U ARE AT IT.
A STAIN WILL NOT HURT THE DECKING BUT ROTTED WILL BE HARD TO REPAIR THE VENT.References :
yes, spray it w/ bleach, then paint on some kilz. goodluck.References :
A little bit of bleach is your best bet. A cup of bleach to a gallon of water is a good formula and you can spray it on and then wipe it off and then repeat a couple of times to make sure it is good. If you are really paranoid of spreading then you can wait until things dry out and then paint it with a good primer like Kilz or something.References :
Bleach is best.References :
spray with bleach it will kill the mold…but be sure to provide adequate ventilation to the attic so the mold wont grow backReferences :
1/2 bleach, 1/2 water in a spray bottle…but don't wait to seal it first, do the spraying now AND after you seal the leak in your A-T-T-I-C. Keep a rag handy to wipe any that trickles. FYI, "Tilex" is mostly bleach but costs a lot more…plain Clorox is cheap and everybody has some for laundering 'whites' and other household chores. P.S.: chlorine is a gas that you DON'T want to breathe…do the spraying and any wiping up that you have to do, then get the heck away from it. and NEVER mix it with ammonia…you'll be sorry;References : handyperson

If you want to try using bleach, don't apply a straight solution. Mix one part bleach to ten parts water.
Since it is surface mold on wood, you may want to try a product specifically labeled for cleaning mold off wood, such as Mold-Care.References :
