How Do You Make An Energy-Efficient House Roof?
An inefficient roof can raise your utility bill in a couple of ways. Whether you are heating or cooling your house, heat will be transferred in during the summer and out during the winter from contact with the outdoor air. Additionally in summer, the roof can be heated directly from the sun’s radiation and transfer heat to the living space, increasing the amount of energy needed for cooling. The main steps involved in making an energy-efficient roof thus include reflecting solar rays and insulating against heat transfer. Determine whether you need dark or light colored shingles. Light colored shingles reflect light waves and ultraviolet waves better than dark shingles. Therefore, light shingles are better for a house in a hot climate, while dark shingles are better for a house in a cold climate. If your house is in a “moderate” climate, you may not know whether you want to absorb or reflect solar radiation year-round. The best rule of thumb is to go with black shingles if you want to f
