If willing to experiment and build a Patio Cover, hammer out questions as to why you need a Patio Cover, for what purpose, whether it would be painted or made with wood, prefabricated aluminum or PVC, and if permission is required from state or city authorities. Remember that a patio is an extension of the house, generally not more than 12 feet and single-storied. The patio can be fully covered or have no cover. No special skills are required for building a Patio Cover except co-coordinating your patience, dimension of area, number of wood or aluminum panels and material required.
Begin with the necessary spade work according to weather conditions, area and usage of patio. The next step is selecting material from a comprehensive range, including polycarb panels for high summer or winter temperatures, vinyl opaque all weather conditions, vinyl translucent and clear panels suitable for use in milder weather conditions, aluminum pan roof that is cool, durable and requiring little maintenance, or insulated foam panels providing insulation for a strong low-maintenance roof. The panels should fit and install easily, and offer design flexibility. Check if the gutter system is accessible for cleaning whether it is w-pan gutter, roll form gutter or extruded gutter and valance.
For that professional Patio Cover you would need appropriate tools; you can order a complete tool kit or purchase one. The tools required would be a 3/8"" drill bit, hack saw or electric jig saw with fine-toothed blade for metal, a caulking gun, measuring tape, screwdriver, hammer, metal snips, socket and shank, crescent wrench, level, carpenter's square, ladders, heavy duty pencils, masonry and nuts and bolts. If the patio is attached to the house then the existing support system will help cover to fit easily. For a free-standing patio the cover will have to be fitted on all four sides, depending on shape. The building instructions will guide you step by step.
