will interfere with the desired
airflow. I stapled extra attic foil
over my gable vents to block them.
The ridge vent is located at the
roof peak where the hot attic
air is least dense, so it naturally
flows up and out. In addition to
this, breezes over the top of the
ridge vent cover create a low-pressure
area to draw even more air
through the attic. The cool air is
drawn in the soffit vents. This can
be as effective as power vents that
Before you run out and buy
vents, first calculate how much
ventilation you need. This is measured
by the net free vent area of
the particular vent product you
select. The net free vent area is
marked on the packaging. It is
always less than the actual area of
the vent because of screening and
other obstructions to the airflow
inside the vent.
Measure the area of the attic
floor. A typical rule of thumb is
one square foot of net free vent
area of each 150 square feet of
attic floor area is needed. This
amount of vent area should be
divided evenly between the ridge
vent and the inlet soffit vents. I
installed multiple 4x16-inch soffit
vents. Check inside the attic to be
sure the insulation is not blocking
the soffit vents. If necessary,
attach small baffles to keep the
insulation from blocking them.
For example, if your attic floor
area is 30 by 50 feet, you would
need five square feet of net free
vent area in the ridge vent and the
same amount in the soffit vents.
If you choose to run the ridge
vent all the way across the roof
because it looks better, even if it is
more ventilation than you actually
need, match it with the proper
amount of inlet soffit vents.
Depending upon how much
inlet soffit vent area you need
and the depth of your soffits,
you may find it easiest to install
continuous lengths of under-eve
soffit vent. This is less time-consuming
than sawing many small
rectangular holes and installing
individual soffit vents.
To install the ridge vent, saw
a slot along the roof ridge with
a circular saw. Based upon how
much free vent area is needed,
determine the vent length needed.
A typical one-foot-wide ridge vent
provides 18 square inched of net
free vent area per linear foot.
Dear Jim: My old house has
real plaster walls. I want to
remove the wallpaper and paint
a light color so the room is
brighter without lamps. What
is the best way to remove the
wallpaper? — Judy K.
Dear Judy: On most walls, a
steamer makes the job easy, but be
careful on old plaster walls. Test
the steam method in an obscure
corner to make sure it does not
damage the old plaster.
Another method is to lightly
spray the wall with warm water
from a weed-type pump sprayer.
To speed up the job, most hardware
stores sell enzyme-based
stripper additives to break down
the old adhesive faster.
