Redrocks Roof and Solar LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity, bound by fairness, honesty and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade, combined with ability, is what makes us true professionals. Above all, we are watchful of our customer's interests and make their concerns the basis of our business.

"Per my contract with Redrocks Roof and Solar, I am to notify them if I suspect my solar system is not producing per their design, and to begin an "underproduction claim". If underproducing, they will compensate for lost production. My system operational as of May 5, 2025, I contacted them in August 2025 informing them of above stated concern. Called 3 times without a response until finally tech came out with last second notice on 9/2/2025. Fortunately I was home, helped him find 9 out of 14 panels that were never wired in. Photos were taken/sent to Redrocks. Additionally, it was discovered a setting on the system phone app given to me to monitor system was not enabled, which they were supposed to explain in detail to me and never did. So for 4 months my system was only producing 33%, Brooke (owner) acknowledged in a live phone call on the spot. I never received parts warranty details per the contract, no response after emails and phone messages about all this. I DO NOT RECOMMEND!!!"

FAQs for electrical wiring or panel upgrade projects in Littleton, CO

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
