How Your Roof Can Affect Your HVAC System
If you have ever worn dark clothing on a hot summer day, you probably could not wait to get home to change into something cooler. That’s because dark surfaces absorb heat. Your roof is no different. A dark roof can raise a home’s interior temperature during the summer. Whether it’s cold or hot outside, poor insulation and inadequate ventilation can also contribute to making your home uncomfortable. These factors can cause your HVAC equipment to work harder.
A Dark Roof Absorbs More Heat
A roof that is covered in dark shingles absorbs heat, which can raise the temperature inside your home during warm weather. The air inside your attic becomes quite hot, and that heat seeps into the rooms below. As a result, your air conditioner has to work harder to cool your living spaces.
A Poorly Insulated Roof Is Less Energy-Efficient
Insulation works to keep cool air in your home during the summer and warm air in during the winter. If your roof is poorly insulated, your home will be warmer during the summer and colder during the winter. Inadequate roof insulation can lead to strain on the HVAC system as it works harder to keep your home comfortable.
A Poorly Ventilated Attic Makes an HVAC Work Harder
Poor ventilation allows heat to become trapped inside an attic. A roof without vents does not allow hot air to escape. An attic that is not properly ventilated requires your HVAC system to work harder to cool your home during warm weather. Inadequate ventilation can cause other problems as well. In hot, humid conditions, moisture can build up in an attic and promote mold growth. Heat and moisture can also cause damage to shingles.
