The work mostly went smoothly. The solar panels are fantastic and I'd recommend them to anyone who has an unshaded, south-facing unshaded roof. However, there were two issues. 1. A worker tossed a cigarette butt off the roof. It landed on the neighbor's patio furniture, burning it. Scalo paid for a replacement, but they shouldn't have been smoking on our property in the first place without asking, and they certainly shouldn't have been careless with disposal of their waste. 2. Part of the job involved repainting a small, metal portion of the roof. The first time they did the job, the new paint peeled immediately. They came back at our request, scraped off the old paint, and repainted it. This looked okay for about 2.5 years, after which point it started peeling again. 3. Also after about 2.5 years, a shingle fell off. I called and asked for them to replace the shingle and repaint the metal roof under the warranty. They agreed. Unfortunately, they did a poor job; they didn't remove the old paint, so the roof looks very bumpy. Worse, they sent me a bill for the painting! They claim it was not covered under the warranty. Reading the warranty, I can see how this is a reasonable interpretation of the text, but they should have told me it would not be covered and given me an estimate before proceeding. Because the conversation was about a warranty repair, I expected it to be covered under the warranty.
