What makes a quality shed?
The short answer
Look at the floor system, framing spacing, siding, and roofing. Real dimensional lumber, treated runners, tight joist spacing, engineered wood siding, and architectural shingles are what separate a 30-year building from a five-year kit. The full checklist is in how to determine a quality shed.
Almost every shed looks fine on delivery day. Quality shows up in year seven, when a thin floor starts to flex or cheap siding swells at the bottom edge. Check the parts you cannot see later.
- Treated 4x4 runners in contact with the ground, rated for water and insects.
- Floor joists at 16 inches on center in sheds, 8 inches on center in garages.
- LP SmartSide engineered siding rather than thin panel or vinyl skin.
- 30-year architectural shingles, not three-tab.
- Painted, sealed trim and real doors with adjustable hardware.
