Replacement
Old siding off, the sheathing beneath inspected, house wrap put right, and new material hung to a proper nailing pattern with room to move.

Where a roof meets a wall is where two trades usually meet as well, and where water gets in while each assumes the other dealt with it.
Step flashing where a roof runs into a wall has to be woven into both the covering and the siding. Done by two outfits a week apart, it is caulked across and called finished. Done by one crew in one visit, it is built the way it is meant to be.
Old siding off, the sheathing beneath inspected, house wrap put right, and new material hung to a proper nailing pattern with room to move.
Storm damage and impact cracks replaced with the nearest profile and shade available, which on a twenty-year-old wall is an honest approximation rather than a perfect match.
Step and kick-out flashing fitted properly, so water leaving the roof lands outside the wall rather than behind it.
Corners, J-channel, and the seals around lights, taps and vents, which is where most wall water actually enters.
A small piece of flashing at the bottom of a roof-wall run, costing very little and left off constantly. Without it, every drop running down that run goes straight behind the siding. A good proportion of rotten sheathing found on this patch traces back to a missing kick-out.
A full tear-off planned around the frontage first, so four tons of old covering leaves the street without closing it.
