"We replaced the original roof on our house. I expressed my concerns about re-installation of the lightening rods to my roofer. We have had at least three direct hits since they were originally installed in 2013. My roofer called William who was very helpful. William offered to come out an make sure everything was 100% after re-installation. He came the day after I called and I'm glad he did. While the reinstall was the best he had seen (his words) there were issues after 5 year and 3 strikes that needed addressed. He fixed those and now I have a new roof and I am certain the lightening rods will work as intended. Highly recommend this company."

Generator Install questions, answered by experts

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.
