HEAT BUILD UP – A YEAR ROUND CONSIDERATION
IS YOUR ATTIC TOO HOT?
Heat can build up in your attic space, year round and can cause problems in both summer and winter. In summer, your attic temperatures rise when solar rays from the sun hit your roof. If the attic is not properly vented, the temperature in the attic will rise. Insulation between your attic floor and living spaces below will slow the heat from pushing down into living spaces but it will not block heat. Eventually, the heat will penetrate the insulation and impact living space temperatures below. This will cause you to run your air conditioner more often and for longer periods to achieve desired room temperatures.
The diagram below shows how proper attic ventilation can dramatically reduce heat build up in your attic.
In the winter, heat can rise from heated living spaces into your attic. Insulation will slow the transfer of heat to the attic, but again it will not block heat. If your attic is not ventilated the heat can build up. During heavy snow, the heat can raise the temperature of your roof, melt the snow and create ice dams at your eaves.
