Video: Roof Fire Safety

SANTA ROSA — Thomas Carrell: A few things to think about with the recent wildfires in California is the products that are installed on the roof being Class A fire rated.

Video: 4 Aspects of Home Maintenance

MARTINEZ — Craig Anderson: You know, most people don’t realize the importance of their rain gutters. They’re actually on the house to protect the structure. A clogged rain gutter can actually lead to dry rot and water damage in the structure itself, or even a cracked foundation, which can cost you an enormous amount of money.

The dust that collects in your home can be caused by dirty air ducts in the home, and it’s important to keep those maintained to keep them clean. It’s also really good for allergies and asthma problems to keep your air ducts clean all the time.

Chase the Sun: Why Now is the Right Time to Install Solar

Posted on February 18, 2021 by James Florence

The ITC allows any homeowner who installs a solar PV system to deduct a percentage of the installation cost from their federal taxes. Both residential and commercial solar installations are eligible for the ITC, and there’s no price cap on its value. Read more
