Since we are planning to try to make this a year around greenhouse in a colder climate, we’re going to install two types of roof system. A standard roof on the north side and corrugated polycarbonate on the south side. This allows us to insulate the north side where we don’t get much sun and it saves us money because polycarbonate is not cheap.

Now that we have the structure up and solid, we have a few things to do before we can install the traditional roof and polycarbonate.

• finish backfilling
• install a small skirt section of roof to cover the dome/building connections
• sheet the north side of the dome and seal the joints before we can shingle.
