I have a 9 year old mountain cabin with metal roofing. The ceiling is very steep cathedral. Off and on since the cabin was built, we have noticed dripping in two locations along wooden support beams that run near the top of the cathedral. The dripping does not seem to be related to rain, snow or snowmelt. Seems to happen intermitently especially after we have been at the cabin for a few days or more. I have checked the humidity at floor level and it is constantly in the dry to low normal range. We never have condensation on the windows. Ideas???

If it is not related to precipitation and if there are no plumbing pipes in the area, then this is undoubtedly condensation. Warm moist air rises and then condenses on something cool. I assume the ceiling has no ventilation. That is unfortunate. Adding ventilation would be ideal but also costly. Are there any sources of moisture inside the home which are not vented outward? Dryer vents, bathroom vents, etc. Does the home even have bathroom and kitch vents? Perhaps you should try running a dehimidifier. Also, visit www.auravent.com for a product that vents direct from inside the house to the outside. It may help you. Again, though, ideally, you need to have ventilation as part of the home's construction. A vapor barrier behind the ceiling would also be helpful.

Todd Thank you for the info. The home does have vents in the bathrooms and for the dryer. There are no vents in the ceiling. I am convinced from other discussions and readings that the moisture is condensation. Do you have a recommendation for a dehumidifier that would work in a home with approximately 1700 sq ft. Thanks again! Curt

I am sorry, Curt. I really do not know anything about particular makes of dehumidifiers. You may find that, for a home that size, you will need more than one. All Best.
