According to statistical data,
around 50% of the money that homes spend on utilities goes toward heating and
cooling. One of the principle components that can be held responsible for
energy loss in homes is the roof – heated or cooled air tends to escape through
doors and windows as well, but the surface of these openings is relatively
small compared to the square footage of roof, which also means that the energy
loss through windows and doors is much less significant, too. Another aspect of
the relationship between roofs and heating bills is that warmed air moves
upwards, towards the ceiling and through the ceiling into the attic – if the
area is not properly sealed and insulated, there is no obstacle that would
prevent heat from escaping.
Beside insulation, there are a
number of other roofing features that affect the way your roof maintains your
home’s thermal balance:
-
Roof color – dark roofs
absorb heat and spread it inside the building, while roofs that feature lighter
colors reflect radiant heat;
-
Roof material – asphalt
roofs reflect around 30% of the direct light they are exposed to, metal roofs
reflect even more, while tile roofs absorb more of the sun’s radiant heat;
-
Roof ventilation – proper
ventilation is important for cooling the attic area, so it affects your cooling
bills in summer. To properly insulate and use the right roofing materials, call on
