Moldy drip edge, staining on interior roof...help!

[Vermontyurters]

Hi friends,

I feel like a “long time listener/ first time caller” over here. I’ve really appreciated all the knowledge shared on this page ever since we thought about building our yurt over a year ago.

We bought a Two Girls Yurt out of NH; we live in Vermont. The yurt stood for a year before we moved in, and we’ve been in it since June.

We are experiencing a terrible challenge with

moisture

and mold. A few months ago, we discovered streaks of water dripping from where the ceiling

insulation

is taped together, staining the interior fabric cover and dripping down where the rafters meet the lattice.

I found mold growing on several sections of our drip edge (plywood edging along the perimeter of platform) and when I investigated found that the bottom of the interior wall layer (reflectix/ fabric combo) was sopping wet at the bottom and mildew present.

We opened the yurt up and I did some cleaning with vinegar, hydrogen peroxide, and baking soda to soak up any remaining

moisture

. Used a hair dryer to dry the fabric/insulation wall and replaced the drip edge.

This seems to be a losing battle and I’m going insane. I’m sensitive to mold and not feeling well on top of the stress of new mold discovery and repairs in the snowy and cold winter months.

Please help. Is this a condensation problem? What can we do? Our yurt maker doesn’t have much to offer us it seems and has said that this hasn’t happened before in his design. We’ve only lived in it 6 months and are already replacing so much. This is the third yurt I’ve lived in and first with this problem.

I’m at a loss. Please send advice!

Notes:
-heat with wood stove, usually cranking daily and through night
-we cook inside but don’t have running water. No showers inside but yes to dishes stovetop cooking.
-floor not insulated
-platform is on a slope with a range of 1-3 feet distance from ground
-although interior roof staining is mostly on north side of yurt, water is still drippping down between

insulation

side of interior fabric and cover and saturating the bottom section of interior wall fabric.
