Questions
Before you commit to attic ventilation in Liverpool
Will a ridge vent stop frost in my old attic?
Not alone. If warm air still leaks up through the ceiling, more venting just moves more of it. Sealing comes first.
Is frost in the attic a roof leak?
Usually not. Frost is moisture from your house air. It melts and drips when the attic warms, so it can look like a leak.
Do two-unit houses need more venting?
Not by rule. They do put more moisture into the house, so the first step is finding and sealing where it gets into the attic.
Do I need to climb into the attic?
No. Look from the hatch with a flashlight and take dated photos. Never step on the ceiling between the joists.
Attic ventilation in Liverpool, NY: air seal first on an old house
Housing in Liverpool village is old enough that its attics may have been changed over the years. Insulation was added, wiring was run, a fan was put in. Each change may have cut a hole in the ceiling.
Federal guidance says to seal air leaks before adding insulation. The energy code adds that batts are not an air seal, so insulation alone will not stop warm air from rising. So the order is: seal the ceiling, then insulate, then vent.
If a proposal begins with more vents, ask what happens to the ceiling gaps. The attic ventilation article explains how much vent area a house needs and why.
Signs
When a Liverpool stain calls for attic ventilation
Frost on roof boards or nails
Look from the hatch early on a freezing morning. Photograph it.
Insulation matted or damp
Look near the eaves and around the chimney. Note where it is wet.
A hatch with no gasket
Feel for drafts at the edges. Note whether the cover is insulated.
One ceiling stained in each unit
In a two-unit house, a stain on both floors points to the attic.
Two kitchens, two bathrooms, one Liverpool attic
About one Liverpool home in ten is a two-unit building. Two households put two sets of showers, cooking and laundry into the same house, and one attic sits above both. That adds up to more moisture reaching the ceiling gaps.
Winter indoor humidity is best kept between 30 and 50 percent, the guidance says. Bath fans should vent outdoors, not into the attic. Check each fan. If one stops short, ask for the duct to be run to a roof or wall cap.
Tell us which floor has the stain, and whether the other unit has one too. Photograph the hatch, the top of the insulation and each fan duct, with the date and the outside temperature. Those photos help you check the proposal when it arrives.
Blocked eaves and what a Liverpool proposal should list
Insulation must not block the eave vents. At each vent the code wants a clear gap of 1 inch or more under the roof sheathing. Federal guidance suggests a baffle that holds 2 inches clear. Look from the hatch at the eave side and tell the contractor what you see.
Liverpool shares the county's Climate Zone 5. The vent ratio starts at 1/150, and dropping to 1/300 depends on keeping 40 to 50 percent of the openings in the upper vents. Ask the contractor how the proposed vents split.
Your written proposal should list sealing, then insulation and baffles, then any added vent area, in that order. Check it against the Liverpool stain page, then send us the form. The Liverpool hub lists the other jobs.
