Questions
Attic ventilation in East Syracuse: short answers
Do I add vents or seal the ceiling first?
Seal first. The federal guide puts ceiling air sealing ahead of added insulation. Ask the contractor to settle the vents after that.
Is a ridge vent enough?
Not alone. Ask where the intake vents sit. If gable vents are also in use, ask about that, since the guide says gable and ridge vents should not be combined.
Can my humidifier cause this?
It can add to it. Most sources suggest 30 to 50 percent relative humidity in the heating season.
How do I know the fan is the problem?
Look at the duct in the attic. If it ends on the floor or under insulation instead of at an outside vent, say so on the form.
Why a two-family sends so much moisture to one East Syracuse attic
Picture what two kitchens and two baths add up to under one roof. Humid air looks for a way out, and the easiest way can be up through ceiling gaps.
Attic condensation needs a cold surface, a gap in the air barrier, humid air and not enough drying. In a double you control the second and third, not the first. That is why sealing comes before venting.
Ask each household to say where its bath fan ends. If either duct stops in the attic, that is the first fix.
Also ask how long the shower and the kitchen fan run. Ask whether the fan is sized and ducted to move steam outdoors, not just to make noise.
Signs
Signs an East Syracuse roof needs attic ventilation
Frost on roof nails on a cold morning
It melts by afternoon and looks like a drip. It is room air that froze on the deck. Look from the hatch and keep off the insulation.
A bath fan duct that stops in the attic
Check both units. A duct that ends on the attic floor puts shower steam straight against the cold deck.
Insulation that is matted or dark near the eaves
Compressed or thin insulation at the eaves leaves a cold strip on the ceiling below, a spot where condensation often shows.
A hatch that does not close tight
A loose hatch lets warm air climb. A foam gasket and some insulation on top are a small repair to ask about.
Sealing before venting in an older East Syracuse attic
The federal guide says to seal air leaks at the ceiling before adding insulation, and calls that the best chance to limit condensation in extreme cold. The code also asks for an air barrier that is continuous, and says soft insulation does not count as a seal.
After sealing, look at vents. Onondaga County is in Climate Zone 5, where the 1/300 vent ratio rests on 40 to 50 percent of the area in the upper vents. Ask what ratio your proposal uses and where the upper vents sit.
Check the eaves too. The code wants a clear gap between the insulation and the roof at each vent, and a baffle beside it. Read how much attic ventilation a house needs before you compare quotes.
When ventilation is the whole fix and the roof is not
If the contractor finds frost, wet insulation and open ceiling gaps, the proposal may be for sealing, a fan duct and vents. That is the repair that fits a condensation stain.

Ask the contractor to describe the order of work: seal the ceiling gaps, fix the fan duct, clear the eave vents, then add or move vents if the count still falls short. The federal guide puts sealing ahead of insulating, so a proposal that skips the ceiling deserves a question.
Ask for the proposal to state that order. If you are still unsure whether your stain is attic moisture, the East Syracuse diagnosis page sorts the other possibilities.
