Greetings,

I have a 60-year-old 1,000 SF brick-and-block raised ranch in
northwestern Illinois. About 17 years ago the original drafty wood
windows were replaced with good quality vinyl and caulked well.
Shortly after that a tear-off roof replacement was done, and an attic
fan and roof vents were added, for a total of 10 vents. There are no
eaves/soffits on the house save for one small overhang at the front
entry. The west elevation (front) is gabled with no vents, the other 3
are hip.

The new shingles curled much earlier than anticipated on the house;
the detached brick garage’s shingles, installed at the same time, are
fine. Due to the lack of intake vents there is a definite
ventilation/moisture issue, and a roofer has suggested a system called
EZ-Flow Eave Vents, supposedly designed for houses like mine. The
brochure for this system is linked below – does anyone have any
comments on the efficacy of this system?

As the gutters are aged and in mild disrepair my thought is to do a
tear-off on the house and gutters, install this EZ-Flow system (run of
116’), a new roof and gutters at the same time. (The garage is fine
but to color match I may add a second layer.)

Additionally, there is a bathroom exhaust fan that is piped and
hanging directly underneath a roof vent nearer the gutter than the
roof ridge. Is it advisable to vent this differently as long as all
this other work is being done? Ditto a kitchen ceiling exhaust fan.
Should I scale back the number of roof vents if I install this EZ-Flow
system, as don’t the intake and exhaust areas need to be balanced? I
realize a good roofer should make recommendations about this but being
a single mom, it helps to be educated in advance.

Thanks for any comments.
