Very important. Balanced intake and exhaust ventilation can reduce heat buildup in summer, control moisture in winter, and help shingles perform as intended. A roofer should evaluate soffit intake, ridge or other exhaust vents, blocked bays, and the attic's overall air path.

Most homeowners should not climb onto a snowy or icy roof. If exceptional accumulation or ice creates concern, use a qualified professional or a roof rake from the ground when appropriate, and avoid damaging shingles or gutters.

Certain warranties can, subject to that warranty's own conditions and a required notification procedure with its own time limit. It is worth knowing the process before the house goes on the market rather than during the sale, and a transferable warranty is a genuine selling point.

The array is professionally removed before the roofing work and reinstalled once the new roof is complete — commonly called a remove and replace. New roof-interface and mounting components are usually advisable rather than reusing ageing penetrations and attachment hardware, though the mounting-system manufacturer's instructions decide what may be reused.

Generally yes when everything else is equal, but size alone does not decide annual production. A smaller unshaded south-facing array can outproduce a larger one that is shaded or poorly oriented. Azimuth, tilt, shading, inverter efficiency and module characteristics all bear on it.
