Leaky Ridge Vents
To the Editor:
A recent storm has caused the kind
of leaks that occur once or twice a
decade. At a house under construction,
the wind blew powdery snow
into the ridge vent [a low-profile plastic
type]. The melted snow leaked
through the insulation and Sheetrock
and onto the floor below (see illustration).
The Sheetrock had been hung,
but not taped. The water on the floor
was in a line below the ridge.
Afterwards, the builder I am working
with laid 6-mil poly on top of the
insulation and collar ties, and
attached it to the underside of the
rafters with furring strips. The theory
is that this will collect moisture [if the
vent leaks again]
