Make Your House Cooler With The Right Roof Products
Using the right kind of roofing products for your home matters significantly when your objective is to reduce heat absorption. For instance, ceramic roof tiles absorb lesser heat than concrete roof tiles.
Because it's the roof of the house is the one that is most exposed to the sun, there is an immediate effect on the house's internal temperature when the roof is warm during the sunny days. 70% of heat entering the house is from the roof. The material used in roofing is primarily responsible for absorption. For instance, ceramic roof tiles absorb lesser heat than concrete roof tiles. Furthermore, lighter colors or shades can also help reflect the heat better than darker ones. Higher roof shapes will have more heat retention space above because heat naturally flows to higher areas. Mitigating heat retention in the house can be remedied through the use of ventilation shafts, eaves, air vents, gables with ventilation louvers, or double roofing. Thermal insulation installed just below the roof either above the ceiling or attached to the roof slope, will help reduce heat transfer into the house.
In the two pictures above, it shows that heat transfers from the roof into the house. With the use of the right roof products, heat may enter but it will reflect and ventilate out of the house.
