of roof ventilator do I get?, ......everything looks the same,.......
how do I know which ventilator is best for my situation?…and
the questions continue on with the frustration allowing you
to fall prey to the first person who sounds as though they know
what they’re talking about when discussing roof ventilators
and ventilation products….maybe they do…chances are they don’t.
face it, in all fairness one doesn’t go out and buy a roof ventilator
that often that they acquire some smarts about what to buy as
they would in say, buying a car the next time around. Roof ventilation
is a one time purchase for most.
In the past
ventilation in general, and roof ventilation in particular,
was something that was intrinsically present in the design of
a house, along with other features such as eaves vents, ceiling
vents, wall vents and sub floor vents, all part of the fundamental
house prerequisite as regards to ventilation products.
venting features are only present in architecturally designed
homes, very rarely in spec homes unless the client has had the
foresight to include ventilation items in his/her building specifications.
less the task at hand is to choose a ventilation product and
or ventilation system. I say ventilation system because you
want both the means of ingress and egress. One without the other

against the so called - dynamic’- ‘turbo’- turbine’- wind driven’-
supa doopa roof ventilator.
also have the roof ventilation gimmick of the decade, ‘the solar
vent’ which presents itself as high tech and has poor overall
performance values and being totally useless of an evening when
you need ventilation the most. Again casting the illusion that
you’re getting great benefit at zero cost. Not when you consider
the overall poor performance of the unit coupled with the early
degeneration of the solar cell, rendering the unit next to useless
in a short period of time.
of the fan itself comes into question.
roof ventilation starts with the correct hole size in the roof,
with only one correctly sized roof ventilator or cupola protecting
and maintaining it's integrity regarding external elements.
you’re considering roof ventilation, think beyond making the
possums more comfortable,....... to what is going to leave you
