Vinyl Patio Cover Cost

How To Build A Gable Roof Patio Cover

The average costs of a vinyl patio cover are between $5 and $13 a square foot installed. Vinyl is one of the lowest-cost options for any cover. It is easy to work with and comes in many different styles. It is also fairly low maintenance but is not as durable as other materials. Vinyl can be made into pergolas, lattice, panels, and many other roofing styles. You may be limited in colors and overall patterns.

Insulated Patio Roof Panels Cost

The cost of an insulated patio roof ranges from $26 to $59 a square foot installed. Insulated patio roof panels help prevent the patio from becoming overheated. This is a particularly good idea if your patio has some type of enclosure or walls like a gazebo. Insulated panels can be made of fiberglass, aluminum, or wood. They come in several different styles and can be added to many different types of roofs or covers. The material being insulated and the overall structure style dictate the final cost.

Step 2: Dig Post Holes

It was a little bit difficult to figure out where to dig the post holes. I wanted them to be exactly 9.5′ from the roof edge, but the houses foundation was recessed 2′ from the roofs drip edge and stuck out 26 from under the bay windows. How was I going to get an accurate measurement? All sorts of neat tools I saw people use on TV shows and formulas from various math classes flashed through my mind. Here’s what I did:

  • I stood up up a couple of posts at the roofs edge, using a bubble level to make sure they were perfectly upright.
  • Then I measured and marked nine and a half feet on a couple of joist boards and laid them on the ground, with one end by the upright posts and the markings on the other end showing where the hole should be dug. I did this at both edges of the ledger board and laid two more ten-foot joist boards between them.
  • I then used my square, or angle iron, to make the corners square.
  • I marked the spots for the three post-holes, with the middle post-hole going where the two 10 foot joist boards met.
  • I then measured corner to corner, one way and then the other, and made slight adjustments until both measurements came out the same. With the exact centers for the post holes marked, I marked 18 circles around them because I planned to dig the holes 18 deep and wanted them to be as wide as they were deep, in accordance with local building codes.
  • Make sure the post extensions are even.

    Where To Attach A Patio Roof Ledger

    On a one-story house, it is often best to attach the ledger for a patio roof just below the houses eaves.

    On a two-story house, you can usually tie the ledger into a band joist , located between the floors, as shown below. Find the band joist by measuring down from a second-story window.

    How To Build A Gable Porch Roof

    Gable roof is the most commonly found type of porch roof. It has a shape of a triangle with a certain pitch and sloped sides. Whether you are thinking of adding a gable porch to an existing roof or building a new one, it is beneficial to help your shed water and snow.

    Here is the guide on how to build a gable roof over a porch you may follow:

  • Decide where the posts of roof support are going to be. Put a mark on the determined locations on the roof deck and the deck areas on the decided spots, so you can set a hole, concrete footing, and set the roof support posts.
  • On the ground, dig the holes for every post spot with a width of 12-18 and a depth of 18. Set concrete in cylindrical shape within the hole and then cover with concrete. Arrange post anchors while the concrete hasnt dried up yet. Then let it sit for at least 24 hours.
  • Size and trim support posts in 6 x 6 that suit the dimensions of the roof. Install the support posts on the anchors and set them loosely using bolts and nuts. You need to ensure that the posts are upright by bracing them tentatively while securing the bolts and nuts.
  • Size and trim two lumber pieces in 2 x 8 that suits the distance between each support post. Lift the 2 x 8 lumbar pieces with the help of someone else, and nail one of the 2 x 8 lumbar pieces temporarily to every side of the support post, but make sure the nails can be removed easily later on.
  • Step 8: Structure The Roof

    To structure the roof, take your 2×6 boards. You can cut them down as needed. Since they will overhang a little bit over the patio, you need to make sure that you do not cut them down at the same length as the patio.

    They have to be a bit longer than the patio. If you have cut them down, you can begin to arrange them so that they cross the joist beams and create a perpendicular pattern.

    Make sure they are evenly placed across the top of the patio. Keep them in place by installing galvanized deck screws.

Drill holes for the expanding anchors every 16 inches or as specified by local codes, insert the anchors, hold the ledger in place, and tap it with a hammer to indent the anchor locations on its back face.

    Remove the ledger, and drill bolt holes where the bolt tips have left marks. Push or hammer the ledger back onto the bolts, recheck for level , add washers and nuts, and then tighten the bolts.

    Fastening A Patio Roof To The House

    A house-attached patio roof takes advantage of the houses structure by supporting one end of the roof on a ledger mounted horizontally to the house. The ledger, typically a 2 by 6, is usually designed to hold one end of the patio-roof rafters. Locating and mounting the ledger is normally a fairly easy process; the ledger should be attached before the foundation is built for a deck, patio roof posts, and other structure.

    Step 4: Assemble The Frame

    The rest of the frame I assembled on solid ground, not wanting to hold everything in place with one hand while installing decking screws with the other.

  • Cut four braces at precisely 45-degree angles. I cut them from a single 10-foot long 2×10 board. I measured the width of the board with a ruler, then marked that length from the end of the board and cut from there to the corner to make a triangle of wood that was exactly the right shape. I measured the short sides of that wooden triangle-shaped block and they were exactly the same so I knew it was cut at a 45-degree angle. I used that to mark the lines I would cut to make the braces. I made the two outside braces three feet long at their outsides and the two inside braces two feet long at their outsides.
  • Joists

    Photo 8: Level And Mark The Beams

    Extend the posts with 2×4 and 2×6 cedar so that they project beyond the top of the ledger, nailing every 4 in. with 16d casing nails up to the beam height. Cut a 2×10 beam member to length and shape the end. Rest it in the joist hanger, level it and mark the height on the post. Cut only the post 2x6s at that height with your circular saw. Cut the center 2×4 9 in. higher .

    Use .60 foundation-grade treated 2x4s and 2x6s for the lower post sections and the footings . You may have to special-order them, but the added longevity is worth the money and trouble. For the above-ground base skirt framing and sheathing, standard .40 treated material will work just fine.

    The base skirts are designed to float, that is, slide up and down the fixed posts that they encase. Thats especially important when they rest on a slab or stone surface in cold regions where frost can lift patios when the ground freezes. The skirts can move up and down during freeze/thaw cycles, but the posts, which extend below frost depth, stay putwithout lifting the entire structure. So when you frame and trim the pilaster base skirts, make sure everything fits loosely.

    If the posts have to penetrate a concrete or stone surface, cut a 20- in. square hole for digging the footings . Use a circular saw with a diamond blade and dont worry about making it pretty; the skirt will cover the hole. To prevent settling, just be sure to pack the soil well as you backfill around the posts.

    Flashing A Patio Roof Ledger

    Unless it will be protected from rain by the houses eaves or a solid roof, a roof ledger that is fastened directly to a house with wood siding should be capped with galvanized metal Z-flashing that tucks up under siding to prevent water from seeping in behind it.

    Where integral flashing isnt possible, such as on a stucco wall, use Z-flashing and caulk the top edge. This is a job you must do before fastening the overheads roof rafters in place.

    You can buy L- or Z-shaped flashing or bend it yourself. To bend sheet-metal flashing, make a form by clamping two 2 by 4s together on each side of the metal, and then hammer the metal to create a sharp edge at each fold.

    Fit the flashing in place, caulk the top edge, and nail it with galvanized nails long enough to penetrate at least 1 inch into the structural members. Then caulk the nail heads.

    If the house is sided with shingles or lap siding, simply slip the metals top edge up under the bottom edge of the shingles or siding as far as possible.


    What Is A Freestanding Patio

    How To Build A Gable Patio Roof – (see description)

    A freestanding patio is a covered patio that sits on your backyard without being supported by the house or other buildings.

    Unlike the ones that rely on the roof, this patio features, at least, four posts that support the cover. That is why it is called a freestanding patio cover.

    Since it sits on its own, it is varied in sizes and heights. It means you can build any patios that suit your style very well.

    What Is The Roof Over A Deck Called

    The roof over a deck is usually called a patio cover. This attached structure provides protection from sun and rain and can either have a solid or open roof. Pergola is another name for deck or patio roofs. This is typically characterized as an open roof thats supported by posts or columns. They provide filtered shade to outdoor living areas.

    Fiberglass Patio Cover Cost

    The cost of a fiberglass patio cover is between $16 and $39 a square foot installed. Fiberglass is one of the materials considered to be the gold standard by many contractors. It is attractive, durable, and very easy to maintain. Fiberglass comes in lattice, pergola, panel, and many different styles, colors, and shapes. Fiberglass is sometimes combined with other materials to give it greater durability. It is also a good insulator, making it a useful option for roofs where the sun is directly overhead.

    Step 9: Double Check For A Better Freestanding Patio Cover

    Now you have the structure of a freestanding patio cover. You can begin to cover the patio with the materials of your choice such as lattice wood, translucent fiberglass, wood and shingles, metal panels , boards and netting, or canvas shade sails.

    The structure that you have just made is the simplest one. There are various kinds of structures available that suit your patio very well.

    But you have to remember to double-check the level of the whole patio before adding the roof. For more freestanding patio cover ideas, check out these ten fantastic patios.

    Make The Patio Roof A Little Bit Higher

    It is almost similar to the first method, but to make the patio roof a little bit higher, you will need to remove the house gutter and place the back channel a bit higher.

    Because the gutter is removed, you will need to install transfer flashing from the roof of the house to the patio. It allows you to add over a hundred millimeters of extra height.

    Cost To Build A Covered Patio Attached To A House

    The cost to build a covered patio attached to a house ranges from $500 to $25,000 on average. A small bistro patio with a sailcloth cover is at the lowest end of this cost. An outdoor kitchen patio with a full roof is at the high end. Because patios come in so many different sizes and styles, the cost range is large. Attaching a patio and cover to the house allows more options. Attached pergolas 1 and awnings can be less expensive than freestanding gazebos.

    Cost To Build A Covered Patio By Location

    How To Build A Gable Roof Over A Patio

    Most patios are located beside the home. This makes them easily accessible and still leaves plenty of space for the rest of the yard and landscaping. But patios can be located elsewhere on the property, particularly if you want them located beside another feature like a pool, tennis court, or fountain.;

    The patio cover can also have different positions. If the patio is located beside the home, the cover can be either attached to the home, extending out over it, or it can be freestanding. When the patio is moved away from the home, the patio must be freestanding, limiting your choices for the cover. Both attached and freestanding covered patios have a wide range of costs because patios and covers come in many sizes and materials.

    $3,000 – $25,000

    Aluminum Patio Roof Cost

    The cost of an aluminum patio roof cover averages $20 to $70 a square foot installed. There are many different aluminum types for patios. You can find aluminum lattice, pergolas, and panels that come in several different gauges. Aluminum can be louvered, installed in slats, or combined with other materials. The thicker the aluminum, the longer-lasting its appearance but the higher its cost. Extruded aluminum costs more than rolled aluminum. Insulated aluminum costs more than extruded and rolled.

    Step 7: Finish The Job

    After that it was simple but repetitive work. I attached 1 x 6 boards to the top of the joists, and then screwed the corrugated metal roof to them. The most difficult part was getting the upper end of the metal sheets to go under the drip edge and roof decking of the house and to butt up against a bead of clear-drying roof cement I had put in there with a caulking gun. Also, putting a bead of sealer along the edge of the metal sheets before overlapping them was a bit demanding, though absolutely necessary.

    The job was done at that point. As for the corrugated metal roofing, I chose rubber washer metal-into-wood screws with ¼ bolt heads and used a ¼ magnetized drill adapted socket to put them in. That type of screw goes into every valley at the top and bottom ends of the panels and every other valley throughout the rest of the roof, into the 1 x 6 boards placed 24 on the center.
