"A warning to anyone considering using Sunlight Solar Energy of Bend Oregon. I had a small system installed on my home in Colorado TWO years ago; a location they no longer service. They installed the system on my roof which was 18 years old, and not in the correct condition ( of which I was unaware) to accept panels as the roof was not well ventilated because of short cuts in the building process. The damage was obvious to every single roofing contractor that came to look at it. I could not detect the damage because the pitch of the roof is extreme. After calling several other reputable solar companies, they all made clear it is an industry standard to not install a roof older than 10 years and all companies advise homeowners to have the roof checked first before installing panels. Never once did Ryan Campbell the installer speak to me about the condition of the roof, which had many years worth of damage. His goal was to get the panels up, take my money and disappear. And disappear they did. Ryan's number disconnected, and the Colorado website page for Sunlight has one digit off so that you can't reach anyone that way either. I did however find a way to contact Paul, the president of the company, and ask for help in getting the panels de-installed and reinstalled after the roof gets replaced (on my dime) given they did not discuss the roof with me prior to install. He first agreed to help me by finding a solar company to take the panels down ( a cherry picker is required because it it so steep $$$$$$) and then refused to help at all a few days later. As someone who runs a small business, I am disgusted. I would never treat a customer this way. As a homeowner, and a professor of environmental sociology who professes the value of solar, I am enraged. This company is awful. Steer as far clear of them as you can. There are other companies deserving of your business."

Earthquake Retrofitting questions, answered by experts

Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.

Earthquake retrofitting can increase your home value, making it a great return on investment. This feature is especially valuable in areas prone to earthquakes. Besides the increased safety value (not only for your family but for the next family who moves in), earthquake retrofitting also helps lower homeowners insurance rates. In addition, having your home earthquake retrofitted can make it easier to get a home loan since they are considered lower risk.

An earthquake retrofit is essential for safety in an earthquake-prone area. Without proper retrofitting, your home is at risk of sliding off the foundation, shifting, or collapsing.

You may also require a retrofit if your home was built before 1980 when building codes began requiring reinforcing, bracing, and bolting for new construction. You may not be eligible for insurance to help pay for earthquake-related damages without a retrofit.

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.
