The cost of a patio cover in Elk Grove depends on the size of the structure, the material selected, whether it is attached or freestanding, and whether a permit is required. Solid insulated aluminum covers cost more than open lattice designs because of the additional material and the thermal performance they provide. Louvered systems with motorized panels sit at a higher price point than fixed covers. The best way to get an accurate number is a site visit where the specific conditions of your property can be assessed.
