Pergola shade can range from decorative partial shadow to near-full overhead cover depending on the roof design and sun angle.
Start with the constraint
Open rafters create moving bands of shade, while adjustable louvers can change the percentage of direct overhead sun throughout the day.
What changes the decision
Low morning and evening sun enters from the sides regardless of roof closure, which is why side screens or landscaping can matter as much as the roof on west-facing patios.
What to verify before buying
Evaluate the patio at the times you use it most. Match roof orientation, louver direction, screens, and accessory options to the actual sun path rather than a noon-only estimate.
How we research pergolas
We prioritize material specification, roof system, published wind and snow engineering, span, drainage, anchoring, installation requirements, warranty, accessory ecosystem, and total configured cost. Local building codes and site-specific engineering take priority over general product claims.
Prices, specifications, firmware, and configuration-driven features can change. Check the current manufacturer page and local requirements before buying or installing equipment.
