Solar in Omaha has to reckon with hail and with shade, and the two are not evenly spread. Older streets under oaks and maples may have a south slope that looks fine from the sidewalk and sits in dappled shade all afternoon. Newer roofs on the west and southwest edges are more open, which means more exposure and a cleaner shot from the next hail core. Granules in the gutter mean the covering is not ready.
The order is boring and it is the whole job. Repair or replace a hail-bruised roof first. Then talk about feet, flashing, and rails. Mounting through a failing slope locks the bad covering in place and makes the next tear-off a circus. Ask what happens to the array when the roof is replaced later, and whose responsibility a leak at a penetration is. A picture from above has not stood in the attic, looked at the deck, or opened the electrical panel.
Many Omaha houses, especially prewar brick, were wired for a different life. The panel may be small, recessed, or already full of tandem breakers. Ask what service is there and what has to change before any inverter is named. Ask for the module and inverter models in plain language, and ask who owns the equipment once it is on the house. Ask who you call when the inverter is silent. If those answers are fuzzy, the roof is not the only thing that is unfinished.
Do not turn this into a fantasy about the meter. Hail can scar glass. Shade from a chimney, a dormer, or the neighbor's walnut can wipe out the hours you were counting on. Snow, late storms, and a west wall that cooks in the afternoon are all real, and none of them replace a look at the roof. The useful questions are structural and electrical: can this roof take the attachments, is the covering sound, and is the service capable.
Say the neighborhood, how old the roof is, and whether hail has already marked it. Mention shade if the south side lives under trees. If a roof claim is open, finish that before you talk about rails. Bring questions about ownership and the panel. Call the number on this page.
