Building ventilation diagnosis, improvement, repair, inspection, standards & specifications: these articles explain how to inspect, diagnose and repair ventilation problems in buildings. We suggest building ventilation methods and we describe the pros and cons of different ventilation approaches used to assure good indoor air quality, low building energy usage, and minimal building moisture problems.

Our page top sketch explaining the wind-washing effect on attic insulation is provided courtesy of Carson Dunlop Associates. At left we show an example of severe indoor condensation at a window. We discuss how to identify and correct various building leaks, moisture, and venting problems such as ice dams, blocked attic ventilation, excessive indoor humidity, how to prevent indoor mold, and how to respond to building floods and similar emergencies. Our photo (left) shows extreme condensation at a building basement window. Moisture at this level risks severe mold growth which can be costly to clean up, and over a longer time this condition invites rot or insect attack on the building. Below is our list of articles on the diagnosis and cure of building ventilation problems.

Frequently Asked Questions about proper building ventilation methods, curing ventilation, moisture, or fresh air problems in buildings, and venting tricky or difficult building designsQuestion: How to fix "Leaks" or condensation problem in roof at un-vented valley rafters?I just built a new house consisting of cathedral ceilings throughout. I installed perforated soffits along the bottom of the eaves, however, I mistakenly forgot to vent the roof along the valley rafters spanning approximately 30' in length. I have discovered a leak at both valley only occuring in the spring time when the temperature finally rises above freezing. I strip back both valleys and re shingled using snow and ice shield as well as torch down roofing, it still leaked at first snow. Is my roof sweating from improper ventilation? I also ran the ridge vent continuously along the peak, should I only have this where the soffit is vented?(not above the valley). I ran styrofoam baffles under all of the sheathing even at the valley rafter, could this be warming the roof where they are not vented to the soffit? Can somebody offer some helpful advice? - Scott Reply:Scott, the ice and water shield approach can stop leaks around valleys - and is a good practice. The fact that you observed leaks when temperature rises above freezing suggests that a pile-up of snow or ice in the roof valleys is melting, that the water load is exceeding the present roof valley's ability to drain without leakage, and that thus water is finding its way under the shingles past the valley and into the building. Waterproofing three feet on either side of most valleys will seem to "fix" this leak, but we really don't want to leave water trapped under the roof shingles either - that can be a source of roof damage and reduced roof life. So in addition to the ice and water shield membrane improvement, take a look at roof valley design details including bends and sealants that prevent water from passing out of the valley and into the roof structure. These three articles should be helpful in curing leaks at your roof valleys for all weather conditions: VENTILATION, ROOF, BEST PRACTICES ASPHALT SHINGLE VALLEY FLASHING FLASHING MEMBRANES PEEL & STICK x Questions & Answers regarding this articleQuestions & answers about building ventilation diagnosis, improvement, repair, inspection, standards & specifications.
