#625 - 01/30/04 12:08 AM attic mold
Anonymous Anonymous Unregistered	We recently had a moisture problem in our attic due to some remolding. We have corrected the moisture problem by adding vents- but not before mold started to grow on the plywood in the attic. How do we clean this mold off the plywood? Are there risks now that we have solved the humidity problem? I have been told bleach won't kill the mold spores - is this true and if so what should we use? Can mold grow on the fiberglass insulation? Are our young children at a health risk? Thank you

You can have all of the intake in the world, but if you don't have the exhaust to accomodate it, it's worthless. The attic will get hot and humid. The moisture will form on the decking under the roof shingles and form a layer of MILDEW! Very seldom do you get a TOXIC reaction unless the wood is rotten and provides a food source for more harmful molds. MY SUGGESTION! Fix the ventilation. Measure the attic and make sure that you have enough intake (sq. footage) and the exhaust ( fans, ridge vent, gable vents etc.) to vent all of the air and accompanying moisture into the atmosphere. ------------------ Jimmy McDonald http://www.StartRemodeling.com Jimmy@StartRemodeling.com http://www.ToxicMoldUSA.com McMoldMan@ToxicMoldUSA.com _________________________ Jimmy McDonald http://www.StartRemodeling.com Jimmy@StartRemodeling.com http://www.ToxicMoldUSA.com McMoldMan@ToxicMoldUSA.com Jimmy McDonald ( RemodelingGuy) specifically assumes no legal liability or responsibility for the accuracy, completeness or usefulness of any information or process disclosed.

Anonymous Anonymous Unregistered	The attic is approximately 900 sq feet. We have three exhaust vents on the roofand six intake vents in the soffits(three on both sides of the house). Do you think this is enough? I'm not sure our roofer knows these answers because he didn't put any vents in when he put on the new roof. Thank you-

provip provip Super Do It Yourselfer Registered: 03/03/01 Posts: 1153 Loc: Victoria, BC, Canada	Sounds like you have enough. Too much is not good either. Rule of thumb for roofs vents with a standard pitch roof say between 2/12 to 12/12 is 1 sq.ft. of inlet usually at the soffits and 1 sq.ft. of outlet(exhaust) usually at the roof peak or gable ends for every 300 sq.ft. of attic, so your roofer didn't need more vents because most vents are about 1 sq.ft. ------------------ Bart Blainey, B.E.R.

Anonymous Anonymous Unregistered	Great, then we should have enough now. Any idea why he wouldn't have installed vents in the roof of soffit when he put the tile roof on?

provip provip Super Do It Yourselfer Registered: 03/03/01 Posts: 1153 Loc: Victoria, BC, Canada	don't understand your question. I thought you already had vents at the soffits? 3 on each side. ------------------ Bart Blainey, B.E.R.

Anonymous Anonymous Unregistered	We do now. We didn't when they replaced the shake roof with tile and that's when the moisture problem started. When we noticed the moisture - they came and added the roof vents. This seemed to stop the condenstaion problem - but I read we needed soffit vents so I asked them to come back and add them. The roofer says the condensation is because the temp. went from the 40's to below 0 quickly. I don't understand why they didn't put the vents in to start with.
