Solar in Salt Lake City has to share a roof with snow, ice, and the east wind. That is the project. Modules on a slope change how snow sheds, where it lands, and how an ice dam behaves at the eaves. A roof that already dams or already lost shingles in a canyon wind is a poor thing to cover and then argue about. Mature trees in Sugar House and the Avenues shade planes that look open from the street. Bench houses take more uplift. A picture from above has not stood in the attic to see stains, and it has not felt a soft deck.
Ask for someone on the roof when it is safe to be there, and ask the age of the covering. Ask whether eaves protection, flashing, and any needed tear-off happen before attachments go in. Ask who is responsible if a penetration leaks and the leak looks like an ice dam. Ask how the array comes off for the next roof. Ask where snow will slide, because a lower roof, a walk, and a bedroom window are all in the landing zone on these streets. Do not skip the ventilation question. A hot attic that builds dams will keep building them under an array.
Open the panel. Older bungalows may have modest service. Houses that added cooling later may be full. Ask for the module and the inverter to be named. Ask who sees production and who you call when a section goes quiet under snow. Ask who pulls the permit and who files the interconnection, and whether the system waits for permission to operate. Ask whether you will own the equipment. Dust and inversion grime are a valley fact. Snow cover is the winter fact.
Bring the roof truth, the tree shade, and the wind exposure. Leave the bill pitch out of the call. Call the number on this page.
