A solid cover is a roof. It gives full shade and keeps rain off, and it introduces the one problem lattice never has: water has to go somewhere.
Solid roof, full shade
Full-shade covered patioBakersfield averages 6.36 inches of rain a year, which sounds like drainage does not matter. It does. The rain arrives in a handful of events, and a low-slope pan with a blocked outlet holds water, which is heavy.
Full shade also changes the space underneath. A solid roof over a west-facing patio removes the late sun that makes the area unusable in August, which is the single most common reason people upgrade from lattice.
A single-skin solid pan still gets hot above you. If the space is meant to be usable at four in the afternoon in July, the honest comparison is against an insulated panel rather than against lattice.
The main reason to choose solid over lattice.
Slope, gutter and where the water lands in the yard are part of the design.
A single skin radiates. Insulated panel is the next step up.
Installed planning range for the Bakersfield market. The calculator separates the structure from the extras and shows the permit as its own line.
The permit is a separate charge set by the City of Bakersfield or Kern County. No current fee schedule for this work is published here, because the only schedule that could be verified was a proposed one. Ask the department for the figure that applies today.
Whichever cover you choose, the same rules apply: Bakersfield adopted the 2025 California Building Code including Appendix I, which is the patio cover appendix, and the 2025 California Residential Code, the structure is designed to a 10 psf live load and an 85 mph design wind, and the openness threshold decides whether you have built a patio cover or an enclosure.
Solid gives you shade and keeps rain off. Insulated adds a foam core, so the underside stays noticeably cooler in afternoon sun. In a climate with a 100 degree season from 31 May to 18 September, that difference is what people notice.
Usually yes. It adds roof area draining to one edge, and with 6.36 inches arriving in a few concentrated events, where that water lands matters.
Yes. Bakersfield adopted the 2025 California Building Code including Appendix I, which is the patio cover appendix, and the 2025 California Residential Code, including the patio cover appendix, and applies a 10 psf live load and 85 mph design wind.
Shading the wall and windows behind it reduces heat gain into the house. That is a real effect, and it is larger with a solid or insulated roof than with lattice.
Planning ranges run about $30 to $52 per square foot installed, with most work near $40.
The material argument is settled here. What is not settled is the span and the insulation.
$28 to $48 per sq ft →02Lattice gives partial shade. In Bakersfield that distinction is not academic.
$22 to $40 per sq ft →04Shade is not the same as cool. A single-skin roof shades you and then radiates at you.
