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

Warning signs that indicate potential service line problems include frequent circuit breaker trips, flickering lights throughout your home, buzzing sounds from your electrical panel, or visible damage to exterior wiring. If your home has an older electrical panel (25+ years) or you notice a burning smell near your electrical connections, contact a licensed electrician promptly to evaluate your system's condition.

Responsibility for electrical service lines is divided between the utility company and the homeowner. The utility maintains everything up to the connection point at your property (often the weatherhead or meter), while you're responsible for the service entrance cables, meter base, and all wiring beyond. Contact your specific utility provider to understand exactly where their responsibility ends and yours begins.

A standard electrical service line replacement takes one to two hours for a straightforward installation. This timeline may extend if complications arise or additional electrical work is performed simultaneously. The process includes disconnecting power, removing old wiring, installing new components, and restoring service. Allow additional time for scheduling inspections and obtaining necessary permits.

Most standard homeowners' insurance policies don't cover electrical service line replacement due to normal aging or gradual deterioration. However, damage caused by covered perils like lightning strikes, fires, or fallen trees may qualify for insurance coverage. Some insurance companies offer specific service line coverage as an optional add-on to standard policies. Review your policy details or consult with your insurance agent to understand your specific coverage options.
