Attic ventilation problem

sserrels · 2007-01-20T18:32:28+00:00

My house is one half of a prefab duplex from the 80's. Last week I wentinto the attic and found mold covering the roof sheathing. It had notbeen there a few weeks earlier. The attic is supposed to be vented bysoffit vents and ridge vent, but I found that the air is not flowing upfrom the soffit to the ridge like it should. The only moving air in theattic is the air blowing in from the ridge vent. The soffits areblocked by fiberglass batts and an additional layer of blown ininsulation. So there's practically no ventilation.Now here's the problem: the roof pitch is something like 2/12 and therafters (except those at the soffit vent) run parallel to the ridge.The pitch is so shallow that I can't get any closer than maybe 10 feetaway from the soffit vent from inside the attic. I can't clear out theinsulation blocking the vents. Plus, if I did remove the insulation,the ceilings of the rooms below would be exposed and uninsulated for acouple of feet from the outside wall.I'm considering buying an electric attic fan and just forgetting thesoffit vent. Any ideas?Shawn
