Why We Verify Ventilation
Requirements
We verify and measure existing ventilation openings. We
diagnose potential problems and endeavor to educate you, the
consumer. We explain your roof’s requirements exactly and we
give it to you in writing. Occasionally a customer will have
reason to decline the ventilation work as proposed. We will
advise that roofing warranties are worthless if proper
ventilation is not addressed. We also advise of potential
conflicts in a given system. Contrary to sales methods used by
most roofing contractors, we will not always advocate the use of
a Ridge Vent. Ridge Vents are a fantastic form of exhaust
ventilation. If used properly, they can do a world of good. If
used improperly, the results can be disastrous.
Ventilation
This is a topic that is largely misunderstood by the Roofing Industry.
Proper ventilation is lauded by almost everyone, and rightfully so,
as a key element in roof longevity and energy savings. The impetus
to capitalize on the issue comes, like most things, from a drive for
profit. Often dominating is the profitability equation, where least
amount of labor expended for the contractor combined with the higher
dollar contract amount equals to higher profit. The ventilation issue
is addressed inadequately, the consumer thinks the recommendation
made sounds right, and everyone is happy, until the problems arise.
An improper ventilation system profits no one, especially the roofer
that stakes a reputation on it.

Fiberglass Shingles Require
Proper Ventilation
The fiberglass base shingles of today are especially susceptible to
overheating. See our page on FIBERGLASS
SHINGLES
Ventilation Is the Real
Imperative
While many roofers focus only on the rooftop, we at Four Seasons Roofing
and Siding like to think about all of the elements of a successful
roofing system. The dynamics have changed for every trade in the modern
era, and all trades must adjust to the new aspects of more efficient
living. The deck boards, fasteners, and overall health of the building
are drastically improved by proper ventilation. The old houses of
a century ago, actually ventilated themselves. The drafty windows
and empty wall cavities allowed water vapor to migrate right out of
the building with less chance of condensation than in today's economy.
Lack of insulation in the attics allowed the summer heat to be dissipated
away. Winter warm spot concentration was less likely to be a problem
on a roof, especially with the Slate or Tile that possess more mass
than contemporary asphalt shingle. The more the mass of the roof,
the more it tends to spread out heat over a larger area. This effect
can be compared to the difference of a heavy cast iron pot on a stove
being heated with uniformity, even though the heat source is concentrated
in a small area. By contrast, a thin pot will burn in one spot over
the heat source, as it transfers heat quickly, absorbing far less
than the heavy pot. Modern window, siding, and insulation upgrades
accentuate the necessity for convective air flow under any roofing
system. There is simply more heat in the summer, with the insulated
attics and air conditioned living spaces, and more condensation and
warm attic potential in the winter, in the absence of a convective
system of ventilation.
More Is Not Better
Many have made the mistake of adding exhaust ventilation to their
roof line. This is not an answer to the call for more ventilation.
It used to be that a roofer could add a vent and rely simply upon
thermal buoyancy for hot air to rise and push out of an attic. New
attic insulation practices and the arrival of the fiberglass roofing
shingle, along with the tighter and more efficient homes has caused
some to rethink their methods. Mixing exhaust vent types is a serious
mistake that is made on most roof tops. Some will say that it makes
no sense to limit exhaust ventilators. These that make such arguments
are not the professionals that hunt down leaks everyday, but the amateurs
that are not experienced with attic ventilation. We will be glad to
discuss your specific attic ventilation needs and make recommendations
after a quick survey of your home.
We provide you with a written ventilation
recommendation based upon government specifications. With this form
and your new roof, you have added value and assurance that your roofing
system will last the test of time.
