What this word covers
Questions
Attic ventilation in Geddes: short answers
What does frost in my attic tell me?
It tells you indoor air is reaching a cold surface. The visit looks for the sources. Send a photo.
What can I see from the Geddes attic hatch on a cold morning?
Frost or dark patches on the roof boards, and damp or matted insulation. Do not step on the insulation or climb in. Take a photo from the hatch and send it with the date.
What is a baffle?
A guide that keeps insulation from blocking the vent at the eave. The code asks for one beside soffit and eave vents.
Does Zone 5 mean my attic needs more vents?
It means the ratio rule has a condition. Ask the contractor which ratio the proposal uses.
Why a Geddes attic sweats before the roof leaks
Attic condensation takes four conditions together, and your ceiling controls two of them: how much room air leaks up, and how humid that air is. In older housing the ceiling was often not built as an air barrier, so it is worth testing.
More than a third of the town's homes predate 1950, and most predate 1980. Housing of that age commonly has gaps around light fixtures, pipes and the attic hatch. You cannot change the weather, but you can close those gaps.
The roof deck is the main surface where water collects, so look into the attic from the hatch on a cold morning, with a flashlight, and keep off the insulation.
Look for four things: frost on nails, damp or flattened insulation, a fan duct that stops short and gaps around the hatch. Photograph each, and send the pictures with the form.
Signs
Signs a Geddes roof needs attic ventilation
Frost on nail tips or the underside of the deck
A white coat in the morning that turns to drips by afternoon is room air condensing on a cold surface.
Damp or flattened insulation
Wet insulation near a fan duct or a chimney chase tells you where room air is entering.
A bath fan that ends inside the attic
A duct that stops before the roof puts shower moisture straight onto the cold deck.
A stain on the ceiling after a dry night
No rain, yet the stain grew. The timing is the clue.
Westvale and older streets: same attic physics, different checks
The physics is the same on every street. The checks differ. In detached housing such as Westvale, one attic belongs to one household, so the fans and the ceiling gaps are all yours to trace. In a two-unit building elsewhere in town, ask who else vents into that attic.
Ask where each bath fan ends. A fan should vent outdoors, not into the attic. Ask whether insulation at the eaves leaves a clear gap at the vent, and whether a baffle sits beside it.
The federal guide also says that gable vents and ridge vents should not be mixed, because the gable openings can short-circuit the airflow. If your attic has both, bring it up.
Our guide on how much attic ventilation a house needs explains the ratios in plain terms.
Geddes in Zone 5: the vent split to ask about
Geddes is in Onondaga County, which is Climate Zone 5. The code allows a 1/300 vent ratio only when 40 to 50 percent of the vent area is in the upper vents. Otherwise the ratio is 1/150.
Ask the contractor which ratio the proposal uses and where the upper vents sit. Ask too whether the ceiling will be sealed first, since the federal guide puts sealing ahead of added insulation and calls it the best way to limit condensation in extreme cold.
Sealing can leave the house damper, so ask how the proposal handles indoor humidity. Most sources suggest 30 to 50 percent in the heating season.
If your stain does not fit the attic story, read the Geddes diagnosis page.
