When looking to purchase a home in the winter months, it is
beneficial to have a look at the roof of the home you are considering.
The roof can tell you a lot about the state of the home and may allow
you to see where unexpected expenses may come into play after you move
in.

A properly insulated and well-ventilated attic will keep cool air in
your home in the summer, and warm air in your home in the winter. A
natural property of heat is that it rises, so a well-insulated attic
will keep that warm air from escaping. After a snowfall, take note of
any snow-free spots on the roof. If snow-free spots exist this means
that warm air is escaping, resulting in higher than necessary energy
costs for you as the homeowner.

While they are beautiful to look at, icicles are also a sign that the roof is not functioning properly.

The icicles are a result of ice damming – a condition that happens
when accumulated snow on a roof melts and then freezes. This freezing
water accumulates, forming a dam, which further prevents melting snow
from draining off the roof. A ridge of ice is formed at the edge of a
roof, where water often builds up and causes unwanted damage, including
torn off gutters, loose shingles, and leaking water into the home.

The root cause of ice damming is heat loss. Heat escapes into the
attic through the ceiling from lack of insulation and ventilation.

Electrical coils on the roof, in the eaves trough and down pipes, are
sometimes installed to reduce the damage caused by ice damming but they
do not fix the problem.

Increasing the insulation in the attic is a start to
correcting/eliminating the problem, but there also needs to be air-flow.
Roof vents, at the top of the roof will allow air to escape, but there
also needs to be a place where the air can enter. By installing
ventilation sleeves at the eaves you will have an air inlet and the roof
vents at the top of the roof will allow air to escape; thereby,
creating good air-flow.

If you suspect that your roof is poorly insulated, or not functioning
properly, it is a good idea to have a professional insulation company
assess the issue at hand.

If you have had any instances where you’ve experienced poor insulation in your roof, please share in the comments!
