Solid roof: shade and shelter, with drainage planned
A solid roof blocks direct sun over the covered area and can provide more protection from overhead precipitation than an open slatted pergola. It is not a promise of a waterproof, enclosed room: wind-driven rain can reach the patio, and performance depends on the selected roof system, slope, joints, edges and connection details. Plan where roof runoff will go so it does not discharge onto a doorway, neighboring property or a spot where water collects. Gutters or other drainage measures may be worth discussing for the site. A slatted pergola is intentionally open overhead; it filters sun while allowing more light, air and precipitation through. Choose between these different uses before comparing layouts.
