can to much roof ventilation cause mold issues

0 votes
I had a roofing contractor contact me because he's being sued for a roof he put on the reason is that the owner says he put to much roof ventilation causing his attic to mold.. However it was stated to the roofer before work began that the homeowner had mold issues in his attic space but never remediated it or hire someone to do so..

Hi Hoferg88,
Too much roof ventilation? It depends how you define “too much”- you might have more (or much more) roof / attic ventilation than recommended standards under one condition; it must be properly designed and balanced. (Attic Ventilation)
If you install it “everywhere”, mixing all types of vents under one roof (gable, soffit, ridge, power, etc.), problems like air turbulence, and dead air pockets formation under the roof can develop. This could result in mold growth.
Besides ventilation there are of course many other “issues” that might contribute to mold growth in the attic. (Attic Mold)
