When your attic is sweltering in the hot summer sun, lowering the temperature will make the space more energy efficient and save your roofing from deteriorating in excessive heat. Depending on your property, there are ways to regulate attic temperatures, and calling an HVAC contractor for help is beneficial. Here are four ideas to try.

How to Lower Attic Temperatures

1. Insulation

Insulation traps heat and stops it from entering your home during the summer, resulting in a cooler space. Make sure your attic has between R-22 and R-49 insulation for the best results. Anything lower will lead to higher temperatures and poor efficiency. In general, about seven inches of fiberglass insulation or six inches of cellulose will do.

2. Ventilation Upgrade

Ventilation also stops heat from building up, which lowers utility bills and saves your roof shingles from overheating. Proper ventilation also keeps your attic dry and lowers the risk for moisture trouble. Make sure your ventilation system is suited for your attic’s size as well as the eaves and roofing of your home. An HVAC contractor can help locate the best placement for vents for optimal circulation.

3. Roof Update

Changing your roof to a more reflective material will help keep temperatures down. Choosing lighter colors for roofing will lead to shingles reflecting more solar radiation, resulting in a cooler attic underneath. Choose white or ivory roofing for the best reflective properties. For even better results, install reflective metal roof tiles.

4. HVAC Contractor

If your HVAC is in the attic, call your trusted HVAC contractor to inspect your current system and ensure there are no leaks in the ductwork and that it is properly insulated. Compromised vents, ducts, and other components can lead to inefficiency and an imbalance in temperatures, which will cause temperature flairs in the attic.
