Conditions come before product choice
How the sheathing, the water-resistive barrier, window flashing, and trim details all tie together decides how long the job actually lasts, not which brand of siding gets chosen.
What a full scope should include
- Existing conditions and likely cause
- Preparation and protection
- Materials, compatibility, and installation details
- Permits, testing, cleanup, and restoration
- Exclusions, warranty terms, and change-order process
Roswell context
What ages cladding here is shade and moisture rather than sun. Dense canopy along the river-adjacent hills keeps walls damp long after the humid summer storms pass, so the recurring failure on north-facing and tree-shaded elevations is biological growth and trapped moisture rather than fading. That is why the water-resistive barrier and the flashing behind the cladding do the real work, and why a wall can be failing behind a surface that still looks sound. Rolling lots contribute splash-back at grade, where siding fails first, and repeated additions leave junctions between old and new wall planes that rarely got a proper detail.
