A new roof offers energy efficiency and peace of mind.
According to experts, a typical roof will last between 20 and 25 years. Which means, eventually, every roof will need to be replaced. The good news? When it's time for a new roof, you can increase your home's comfort and energy efficiency with a cool roof that can lower your energy costs.
When To Replace Your Roof
Most people don't realize that they need a new roof until it starts to leak. By then, there may already be damage to the home. It's important to have your roof inspected by a roofing company, or take a look yourself as your roof gets older. Check for shingles that are curling, buckling or missing, especially in the "valleys" where water drains into gutters.
Building Codes Are Local
Building codes vary from state to state. For example, in California, roofs must meet the requirements of CA Title 24 - the California Energy Commission's Building Energy Efficiency Standard. That covers Cool Roofs (for hot climates) and Performance Roofs (for cooler climates), which are designed to keep heat inside the house. Be sure your roofing contractor explains your local code requirements.
Going With A Cool Roof
Roofing with high solar reflectance (SR) and thermal emittance (TE) properties are known as "cool roofs." These properties help reduce electricity used for air conditioning by lowering roof temperatures on hot, sunny days. Solar reflectance refers to a material's ability to reflect the sun's solar energy back into the atmosphere. Thermal emittance provides a means of quantifying how much of the absorbed heat is rejected for a given material. Both properties are measured from 0 to 1 and the higher the value, the "cooler" the roof. Together, these properties can help roofs absorb less heat and stay up to 50-60°F cooler than conventional materials during peak summer weather.1
Benefits of Cool Roofs
- Cool roofs deflect some desired heat gain during the winter, but in general, cool roofs result in net energy savings, especially in areas where electricity prices are high. Energy cost savings can be up to 20%, depending on materials, climate zone and electricity rates.
- Improved occupant comfort
- Reduces air pollution and greenhouse gas emissions
- Lasts longer than standard roofs
