Pro Tips

✓ Freestanding pergolas need concrete in every post hole — min 2 feet deep or below frost line
✓ Attached pergolas must be lag-bolted into wall studs or a ledger board, not just siding
✓ A shade sail is faster and cheaper but provides less structure and UV protection
✓ Add a ceiling fan rated for damp or wet locations — outdoor fans cool more than shade alone
