Solar in Albuquerque has the sun and a roof that goes cold every night, often a flat one already wearing a swamp cooler. That is the site, not a generic slope with a clear southern view. Membranes and built-up roofs take different attachments from shingles. Parapets throw shade across part of the plane. The cooler, the curb, and the service space around them eat the middle of many roofs. Wind at the foothills and across the mesa will test the fastening. A picture from above misses ponding, a soft spot, and the cooler leak you already know about.
Ask for a person on the roof. Ask the age of the membrane or the shingles and whether that work happens before any module is set. Ask the attachment detail and who stands behind a leak at the penetration. A leak on a flat roof does not announce itself politely. Ask how the array comes off later without destroying the covering. Ask how the cooler stays serviceable. If the house is pitched shingle instead, say so, and ask about wind and about the cold-night wear on flashings.
Then the panel. Older houses in the valley can have modest electrical service. Newer houses may already be full. Ask for the module and the inverter to be named and for the panel to be opened. Ask who sees production and who you call when a section goes quiet. Dust from spring wind films the glass. A light snow will cover it and then melt. Ask how access works so nobody is walking a membrane as a path.
Ask who pulls the permit and who files the interconnection, and whether operation waits on permission. Ask whether you own the equipment. Bring the roof shape and leave the bill story out. Call the number on this page.
