A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles. Nearly any type of building can benefit from a cool roof, but consider the climate and other factors before deciding to install one.
A cool roof can benefit a building and its occupants by:
- Reducing energy bills by decreasing air conditioning needs
- Improving indoor comfort for spaces that are not air conditioned, such as garages or covered patios
- Decreasing roof temperature, which may extend roof service life.
Beyond the building itself, cool roofs can also benefit the environment, especially when many buildings in a community have them. Cool roofs can:
- Reduce local air temperatures (sometimes referred to as the urban heat island effect)
- Lower peak electricity demand, which can help prevent power outages
- Reduce power plant emissions, including carbon dioxide, sulfur dioxide, nitrous oxides, and mercury, by reducing cooling energy use in buildings.
There are many types of roof systems available, but the surface exposed to the sun is the one that determines if a roof is cool or not. You can usually make a new or existing roof cool by selecting the appropriate surface.
Cool roof coatings are white or special reflective pigments that reflect sunlight. Coatings are like very thick paints that can protect the roof surface from ultra-violet (UV) light and chemical damage, and some offer water protection and restorative features. Products are available for most roof types.

A wildfire is burning out of control, and your house is in its path. What do you do?
Most importantly, if you have been ordered to evacuate by authorities, get out immediately. Leave with your family, pets, important papers and whatever portable prized possessions you can quickly pack. Lingering could be fatal.
If no evacuation has been ordered, but you anticipate that one could be in the near future, here are 10 things you can do to make your home safer, according to Cal Fire, the Federal Emergency Management Agency, Weather Underground and DisasterSafety.org.
1. Call 911 to inform authorities of your location and the location of the fire.
2. Shut off your house’s gas supply. Move propane tanks at least 100 feet away from the house.
3. Fill sinks and tubs with cold water.
4. Keep doors and windows closed but not locked. Leave the chimney damper open, but cover the fireplace opening with a screen.
5. Turn off air-conditioning. Unplug televisions, small appliances and other electronics, but leave lights on in every room to increase visibility in heavy smoke.

San Diego County home prices in October did not increase from the previous month for the first time since May.
The median home price for all homes — single-family, condos, townhouses — was $650,000, unchanged from last month, said CoreLogic data provided by DQNews on Wednesday. The price is still up a substantial 13 percent in a year, but marked a rare slowdown in price appreciation that has defied expectations throughout the pandemic.
Many of the circumstances that experts say have driven up prices across the nation are still present: Record low mortgage rates, lack of home inventory and desire to own a home as many people are stuck working outside offices.
