Summer’s coming and that means big utility bills from our cooling costs. According to the Department of Energy, a dark roof can be as much as 50 degrees warmer than the outside air temperature. The heat absorbed by your shingles can also heat your home. In the winter, this isn’t a bad thing, but in summer it can end up costing you. If you want to improve the energy efficiency of your roof, here are some tips.
Many homeowners don’t realize that the insulation installed by their builder in their attic may or may not be up to current code or recommendation. The recommended R-value of attic in most of Florida according to the Department of Energy is R-30 to R-60. Most homes built before 1982 aren’t properly insulated. A good rule of thumb is to go into your attic and look at the insulation compared to the floor joists. If the insulation is below the joists, you don’t have enough insulation. If you aren’t sure, measure the insulation, nine inches is about R-30 and 12 inches is R-38.
When your attic is properly ventilated, it allows the hot air to escape. It also allows moisture to escape. Both will help keep your home cooler and an added benefit is that your roof last longer. There are many types of venting for attics. Newer construction has ridge vents along the roof’s peaks, older homes have box vents. All homes should have soffits. Make sure yours aren’t blocked by insulation or organic growth.
Use Energy-Efficient Materials for Your Roof Replacement
If it’s not time for a roof replacement, this isn’t going to be your first course of action. If, however, you need a roof replacement, consider one of the many energy saving options. The most common is the ENERGY STAR® rated cool roofing products from companies like GAF. Another option is choosing a lighter color shingle, like a light tan rather than a dark black. Metal roofing can also be very energy-efficient. Talk to your roofing contractor about your energy saving goals and they can help you choose the right option for your home and budget.
Although a roof replacement is often the way to increase the energy efficiency of your roof the most, if you don’t need one, start with proper insulation and ventilation. Your roofing contractor can evaluate your home and make necessary changes if your home is lacking in either.
