OneRoof Energy reviews

The Verdict
We can't recommend OneRoof Energy. Over months of analysis, we found a pattern of installations that start with holes in the wrong places and end with homeowners who can't get anyone to call them back. One homeowner spent 23 months with a damaged roof because the installer changed the panel layout without asking, water poured into his pool, and repair attempts dragged on until he stopped paying his bill just to force a response. Another watched his system lose half its output over a decade while the company, which leased the panels and promised to monitor them, became unreachable. Thirteen reviews mention project management failures. Nine detail post-sale support breakdowns. The handful of positive reviews praise individual reps like Timothy Thomas, but they also note six-week delays due to poor internal communication and systems underperforming by 20 percent at go-live. We heard about condenser units shoved against each other mid-repair, incentive checks that never arrived four months past due, and billing clerks who charged seven dollars extra if you refused autopay access. If you need solar that actually works when the installer walks away, keep looking.
If you're comparing solar quotes, cross OneRoof off your list. The rare homeowner who lands a competent project manager may skate through, but most face a gauntlet of roof damage, phantom repairs, and support staff who ghost you the moment a problem surfaces.
Reviews That Shaped Our Verdict
Alex W. began a July 2012 consultation that included a promise of an $800 incentive check once his system was interconnected. He had the panels installed and the system went live in October 2012, but four months later the $800 still hadn’t arrived. He phoned and emailed repeatedly and found himself bounced between company contacts with no resolution. He left a one-star review after months of unresolved follow-up. The detail that stuck: a clear promise of an $800 payment vanished after installation, and repeated outreach produced no fix.
In 2012 Big D. had OneRoof Energy install 36 leased solar panels on his house — each panel rated at 0.19 kW and the system listed at a 6.4 kW output. Over time he watched production fall, and by 2025 the array was only generating about 3 kW, roughly half of what the system was supposed to deliver. Because the panels are leasehold, OneRoof carried responsibility for monitoring and maintenance, and he has been trying to get hold of them to address the drop in performance. The most striking detail: a long-term leased system that initially promised ~6.4 kW now produces ~3 kW, yet the homeowner remains dependent on the installer to follow through on upkeep.
Russ D. hired the company to put solar panels on his residential roof—one that drains toward a backyard swimming pool—and while the system’s performance has been fine, the installation and billing turned into a drawn-out headache. He and the sales consultants had agreed on a mounting plan, but the technicians arrived with a different layout and placed panels so that rainwater now ran past the gutters and dumped straight into the pool, a change made without consultation. The crew later reinstalled the array to match the original plan, but left extra holes in the roof and lifted shingles. Billing added to the frustration: customers must enroll in automatic withdrawal or pay a $7.50 monthly fee to mail payments, there’s no web-pay option, and the billing clerk showed little interest in feedback—enough that he didn’t feel comfortable giving automated bank access. On October 2, 2016 he stopped paying to get attention. The company finally responded, waived the $7.50 fee, and sent a contractor to assess the roof. That contractor showed up months later without notice, delivered enough matching shingles to finish about half the repair, and then didn’t return despite repeated calls. By a

JoshLu H. had a residential solar system installed on his New Jersey/New York–area home and worked directly with Timothy Thomas as both energy consultant and project manager. He prized having a single, consistent contact: Tim answered questions promptly and patiently, stayed professional without being pushy, and even came by shortly after activation to make sure the system was running well. The job encountered a hiccup when communication between the east- and west-coast offices created about a six-week delay, but otherwise the process felt worry-free and hands-off. OneRoof took care of the paperwork, engineering, contractor coordination, and permitting, and the flip-the-switch moment was straightforward and uneventful. Performance is still early: on the sunniest days the array has produced roughly 80% of its designed capacity, an unexplained shortfall he hopes the company will investigate. Even so, the system already delivers about 65% of his household electricity, which he finds thrilling. He gave the overall experience four stars and keeps telling neighbors in NJ/NY to ask for Tim — the uninterrupted, involved project manager made the difference.
Cory M. finally flipped his solar system on after the installation. He found One roof kept him informed at every stage, providing steady updates and going out of their way to answer every question. The detail that stuck with him was their responsiveness—he always knew what to expect next.
