What this word covers
Questions
Before you commit to attic ventilation in Manlius
Should I add more vents to my Manlius attic?
Not before sealing air gaps and checking that existing vents are open. The Department of Energy guide tells you to seal air leaks ahead of insulating. Ask the contractor what the attic needs most.
Can I use gable vents and a ridge vent together?
The Department of Energy advises against it, because the gable openings can short-circuit soffit airflow. Ask which one the contractor would keep.
How do I look at my attic?
Only from the hatch opening, with a flashlight, and keep off the insulation. Look at the deck near the eaves, the insulation edge and the vents. Write down what you see, and let the contractor go further.
Attic ventilation in Manlius: two ages of attic, two checks
In the Town of Manlius, 38.3 percent of housing was built in 1980 or later, and 11.2 percent dates from 1939 or earlier. Attics from those two ends of the range tend to need different questions.
In an older attic, ask whether insulation is laid thick against the roof at the eaves. The code asks for at least a 1-inch space between insulation and sheathing at the vent. In a newer attic, ask whether it has soffit vents, baffles and a ridge vent. There the question is whether the baffles are in place and whether the gable vents were left open.
Both are checks you can describe to the contractor without climbing anywhere. If you look at all, look only from the hatch opening with a flashlight, and keep off the insulation.
Signs
When a Manlius stain calls for attic ventilation
Frost or dark spots on the roof deck
Ask the contractor to check the deck near the eaves first. Cold collects there.
Insulation pushed up to the roof at the edge
It can block the vent that is meant to bring air in.
Both gable vents and a ridge vent
Used together they can short-circuit the airflow.
A hatch with no gasket
Warm air leaks around a loose hatch straight into the attic.
Baffles, ridge vents and the gable vent trap
A baffle holds insulation back from the eave so air can enter. The energy code requires one next to soffit and eave vents when the insulation is air-permeable. The Department of Energy puts the clearance at 2 inches between the deck and the top of the insulation.
Gable vents together with a ridge vent can defeat the soffit airflow. If your house has both, ask the contractor which one the proposal keeps and why.
Under section R806.2 the Manlius attic starts from 1/150 net free vent area, and 1/300 is allowed only when 40 to 50 percent of it is in the upper vents. Onondaga County is in Climate Zone 5, so only that upper-vent split applies, not the retarder condition meant for Zones 6 to 8. Ask the contractor to show your upper-vent share in writing.
Seal first, then vent: what a Manlius proposal should say

Vents alone do not stop a warm-air leak. Sealing the attic floor comes first. A tight, continuous air barrier is a requirement of the energy code, and loose insulation does not count as one.
The proposal should list what gets sealed, what gets vented, and in what order. Ask about the hatch too. A hatch should be gasketed and insulated like the ceiling around it.
If you are not sure the stain is attic moisture at all, begin with roof leak diagnosis in Manlius. The guide on how much attic ventilation your house needs has the vent math.
