Roof moisture problem


I recently found a moisture problem in an unfinished attic space. The area is insulated with baffles between the insulation and roof. The roofing is intact. I recently had to replace the roof vent. I went from aluminum roof vent to the Air Vent Shingle Vent II from Lowe's. Now I find moisture on all the baffles. In one area it's even dripped onto the sidewalls. The attic area is heated. There was no condensation last year with the old roof vent. The only thing that's changed is the roof vent. Has any one else had problems like this?

It sounds as if you reduced the airflow. That's the only change in the system you mention.

Roof moisture problem


Tinners right,There`s a big difference in volume,and mesh baffles in the shinglevent II that are meant to stop the water going thru

Roof moisture problem


Ridge vent won't work at all without equal or greater intake ventilation. However most mushroom vents, while work better with an intake, will still work somewhat without the intake. Is there an intake? In this space, how much insulation do you have? What is the architecure of the roof? It's not good to install a ridge vent on a hip roof, in most cases. Do you have a bathroom or kitchen vent dumping into the attic?

You say the attic space is heated? Am I to assume you have a furnace in the attic supplying heat to the rest of the house? Those are ALWAYS a problem in my experience, and require additional ventilation. What is the humidity level set at on the furnace? Is it possible there is a break somewhere in the duct pumping warm moist air into the attic? Have you sealed all the joints in the duct work with metal faced duct tape?

Hi K Faust,
Moisture in your roof is definitely not good. I would look into getting a professional roofer before the problem gets worse.

This is a list of roofing companies. Maybe it will help. Good luck.

They have moisture in the attic and you are telling them to paint their roof.
