The primary factor of a cool roof to consider in your decision process is that it provides numerous advantages. Just as it is with any product, there are a couple of downsides. Whether the benefits outweigh the disadvantages depends on multiple requirements, and you’ll need to be the last judge.
Lower Energy Costs
The less heat that’s transmitted into your house from your roof the cooler your home will be and the less you’ll have to run your ac system. Inning accordance with the Cool Roofing System Rating Council, that savings can be anywhere from 7% to 15%.
Much better Convenience
Even if you do not use/have air conditioning, a cooler home throughout the warmer months of the year tends to be comfier. The chimney effect (where the more heated air increases upwards) can make the upper floor warmer than the primary level if you have a two-story home. Integrate that with a hot roof that transfers heat from above, and it can make for some uncomfortable sleeping quarters.
Extended Roofing Life
Extreme heat can trigger more quick degradation of your roofing, particularly one with asphalt shingles which naturally break down gradually with direct exposure to the sun. The longer your roofing system lasts, the fewer times you’ll have to re-shingle.
Possibility For Rebates
Utility companies in some municipalities provide refunds for the installation of energy efficient roof. Consult your energy business directly to see if they presently use a refund.
The Cool Roof Ranking Council, a non-profit organization, chartered with establishing techniques for labeling and evaluating energy efficient roof has a listing of rebate programs at the ‘resources’ area of their website. However, these listings can often end up being out of date. You can utilize them as a very first effort, but it’s recommended to examine directly with your local energy company to confirm.
The previously mentioned benefits are direct benefits, suggesting they benefit you directly. Energy efficient roof likewise comes with some ‘trickle-down’ benefits too that are spin-offs of the immediate advantages.
For example, using less energy because you do not need as much air conditioning is always a benefit to the environment. It lowers electrical demand which translates into less fuel required to produce the electrical energy.
Roofing systems that have longer lives imply there’s a decrease in the frequency and quantity of roofing scrap that goes into garbage dumps when an old roofing system is detached and a new roofing system installed.
Energy efficient roofing likewise help in reducing the urban heat island effect that results from the emission of excess heat from hot roofs in a city environment. The more cool roofs that are installed, the less recurring heat is emitted, keeping overall temperature levels somewhat lower than would be otherwise. This can have a total positive advantage in the reduction of a city area’s cooling requirements.
Lighter Roofing System Colors May Look Dirtier Quicker
The lighter colors associated with some cool roof items, especially a few of the light gray asphalt shingles, may develop algae streaks and reveal dirt quicker. Some asphalt shingles contain constituents like copper to assist in postponing the beginning of algae, but it won’t ward off contamination and other natural deposits.
Cool Roofing Might Cause An Increase In Heating Requirements
Throughout the winter a house’s roofing can make practical use of any heat energy taken in from the sun. A cool roof works against this process and might need an increase in winter season heating. To precisely what extent is identified by geographical place and the typical qualities of the winter season like duration, snowfall, and the standard variety of cloudy vs. warm days.
On this last point, you’ll discover info from various sources that specifies that the extra heating energy required because of the cool-roof result throughout the winter season is offset by the reduction in power needs to cool your home throughout the warm months. That may hold true for some environment zones however not all.
If you think of it regarding annual cooling and heating days, you can make your evaluation on whether you reside in an environment that has more heating than cooling requirements primarily. If that’s the case, then the advantages of energy efficient roof might be lessened.
