There are many different options for how viable you want your roof to be. Your roof is the first line of defense against wind, rain, sun, and other weather conditions. It is also how a large amount of the heat enters and exits your home. During the summer, the heat of the sun will warm the roof throughout the day. That warmth will then come into your home. Since heat rises, it will escape through the roof during the winter as well. If you have a heater on, you will lose a large amount of the heat through the roof. Roofers can help you reduce the amount of heat you lose through the roof or how much comes in during the summer.
