Roof vents, also called attic vents, are an essential part
of a home ,well-being, but they could also be a source of roof repair problems.
The blinking around the roof vents could be incorrectly installed into the
layers of roofing material or incorrectly covered, leading to leaks. Leaks are
tricky things; water drips or gets blown in, travels by capillary wicking
action and also by gravity sometimes to locations far from the source of the
water.
However, without vents, your attic would build up heat,
sometimes to 160 degrees that would cook your Virginia (VA) roof from the
bottom up. While this may not issue as greatly in metal or tile roofs, extreme
heat can seriously shorten the lifespan of shingle roofs which are often
guaranteed for 25 years. In the summer and winter, the air in the attic of a
house offers a required insulation zone, but if the air doesn't move, the heat
radiates into your house and can cause your utility bills to rise. Without
proper air flow, it also deteriorates the construction of your roof by baking
the wood in the summer and submitting the wood and insulation to mold, mildew,
and ice in the winter.
It's up to you if you think you can sneak and get it. It
occurs when you have absolutely no leaking anywhere in your roof.
As professional roofing contractors, we take the mystery out
of the impossible on a daily basis. The extremely humble truth of the matter is
that without proper air flow in your attic, so much moisture builds up, you may
as well be living underwater. You'll be overtaken by mildew, row and mold. The
four strong winds may blow lonely, but with your new roof fan they'll be in
good company.
Roof vents are required for the placement of air from outside to move in
to your attic and air from the attic to move outside. It is important for a
well-insulated home. In fact, effective roof ventilation will actually reduce
your energy costs and will prolong the life of your roof sheathing, shingles,
and insulation. Roof vents provide the much needed ventilation points in
improvement to the gable end vents and eaves.
Roof styles such as hip and mansard roofs especially need
roof vents as there aren't any gable ends to vent out the hot air. Roof vents
are also needed because sometimes when designers design the gable end vents,
the size is decided more by the design of the house than the airflow needs of
the attic. Ideally, all the air in an attic should change out about every two
and one half minutes. Adding roof vents lets off the extra heat, adding a vent
to your cement tile roof helps to increase the flow
