Asphalt roofing is one of the most popular roofing materials used in residential and commercial buildings. While it is known for its durability and affordability, asphalt roofing can also contribute to energy efficiency and help reduce energy bills. In this article, we will explore the relationship between asphalt roofing and energy efficiency, and provide tips on how to reduce your energy bills.
The Impact of Asphalt Roofing on Energy Efficiency
Asphalt roofing can affect energy efficiency in several ways. During the summer months, a dark-colored asphalt roof can absorb heat from the sun, causing the temperature inside the building to rise. This can lead to an increase in cooling costs, as the air conditioning system works harder to cool the building. On the other hand, a light-colored asphalt roof can reflect sunlight and heat, reducing the amount of heat that enters the building.
In the winter months, a well-insulated asphalt roof can help to retain heat inside the building, reducing the need for heating. However, if the roof is not properly insulated, heat can escape, leading to increased heating costs.
Ways to Improve Energy Efficiency with Asphalt Roofing
There are several ways to improve energy efficiency with asphalt roofing:
- Choose a light-colored roof: As mentioned earlier, a light-colored roof can reflect sunlight and heat, reducing the amount of heat that enters the building. This can be especially effective in warm climates.
- Use a cool roof coating: Cool roof coatings are special coatings that can be applied to the roof to reflect sunlight and heat. These coatings can be applied to existing asphalt roofs, and can help to reduce energy costs.
- Install solar reflective shingles: Solar reflective shingles are a type of asphalt shingle that is designed to reflect sunlight and heat. These shingles can help to reduce energy costs, and can also help to extend the life of the roof.
- Ensure proper insulation: Proper insulation is essential for energy efficiency, regardless of the type of roof. Ensuring that the roof is well-insulated can help to retain heat in the winter and keep the building cool in the summer.
- Maintain the roof: Regular maintenance is essential for ensuring that the roof is functioning properly. This includes cleaning the roof, inspecting for damage, and making repairs as needed.
Additional Tips for Reducing Energy Bills
In addition to improving energy efficiency with asphalt roofing, there are several other ways to reduce energy bills:
- Seal air leaks: Air leaks can allow heated or cooled air to escape, leading to increased energy costs. Sealing air leaks around windows, doors, and ducts can help to reduce energy bills.
- Upgrade to energy-efficient windows: Energy-efficient windows can help to reduce heat loss in the winter and heat gain in the summer.
- Install energy-efficient lighting: Energy-efficient lighting, such as LED bulbs, can help to reduce energy costs.
- Use a programmable thermostat: A programmable thermostat can help to regulate the temperature in the building, reducing energy costs.
- Consider solar panels: Solar panels can provide a renewable source of energy, reducing reliance on fossil fuels and lowering energy bills.
Conclusion
Asphalt roofing can play a significant role in energy efficiency, and there are several ways to improve energy efficiency with asphalt roofing. By choosing a light-colored roof, using a cool roof coating, installing solar reflective shingles, ensuring proper insulation, and maintaining the roof, building owners can help to reduce energy costs. Additionally, by following other energy-efficient practices, such as sealing air leaks, upgrading to energy-efficient windows, installing energy-efficient lighting, using a programmable thermostat, and considering solar panels, building owners can further reduce their energy bills. By taking a comprehensive approach to energy efficiency, building owners can help to reduce their environmental impact, while also saving money on energy costs.
