Attic Insulation in Rancho Palos Verdes, California

The Rancho Palos Verdes coastal climate is mild, but the sun still heats the attic in the summer and the winter nights still leak the heat. Many of the older hillside homes are under-insulated. Attic insulation in Rancho Palos Verdes keeps the home comfortable and the energy bills low.

Signs Your Rancho Palos Verdes Attic Needs Insulation

• The rooms upstairs are too warm in the summer — the heat is coming through the ceiling
• The energy bill is high year-round — the heat is leaking through the roof
• The insulation is below the level of the floor joists — the attic is under-insulated
• The house feels drafty in the winter — the air is leaking through the attic
• The attic is damp or musty — the insulation is not working with the ventilation

Why Rancho Palos Verdes Homes Need Attic Insulation

Many of the older hillside homes in Rancho Palos Verdes were built before the modern energy codes. The attic insulation was never upgraded, and the heat leaks through the roof in the summer and the winter.

The insulation slows the heat transfer. In the summer, it keeps the attic heat out of the living space. In the winter, it keeps the house heat in.
