Method 3 Galvanized Post Brackets Bolted To Existing Concrete Slab

  • Fix the brackets to the slab, in position with masonry bolts or anchors.
  • Install the posts plumb in the brackets and hold in place with temporary bracing.

Trimming the posts

  • Mark the rear posts a minimum of 2300mm above the slab, or finished ground level.
  • Ensure the height marks on both rear posts are level. Use a spirit-level on a straight edge to achieve this or a water level. For instructions on how to make and use a water level go to here.
  • Mark the front two posts 100mm higher than the rear posts.
  • Fix a string line between the front and back posts to mark the height of the middle posts. Cut the tops of the posts off at these marks.

Pay Attention To Flashing And Roofing Details For A Watertight Job

Building the tie-in framing on top of the existing shingles is a good way to keep the house waterproof as you construct the porch, but when it comes time to install the roofing you’ll have to cut the shingles along each of the valleys with a hook-blade utility knife. Then pry loose the cut shingles to make a wide path for the valley flashing.

Cover the tie-in framing with 3/4-in. plywood. Add blocking as needed and fill in the triangular areas between the existing roof and the new roof.

Build The Deck Square And Level And Assemble The Perimeter Joists

Install the ledger board.

Start by marking the ledger board location on the house wall. We located the top of the ledger board 90 in. below the bottom of the soffit. On our house, this left a 6-in. step down from the patio door to the deck surface. Remove the siding and attach the ledger with 1/2 x 4-in. galvanized lag screws . Make sure it’s perfectly level. If the ledger attaches to concrete, predrill holes and insert lead shield lag screw anchors before installing the lags.

Outline deck frame and set beams. 

After you mount the ledger, use stakes and string lines to outline the deck frame according to the dimensions in Figure B and mark the footing locations. A few days before you plan to dig the footings, call 411 to have underground utilities marked in the vicinity of the porch. Your local building department will specify how large and deep the footings should be for your climate and soil conditions. Pour a concrete pad in the bottom of each footing hole after they’ve been inspected. Let the concrete set overnight.

Assemble Frame.

Next, choose the six straightest 2x10s for the perimeter beams. Cut the 2x10s for the two side beams to length and nail the pairs together. Use 16d stainless steel or double-dipped galvanized nails for all of the joist framings and to attach the joist hangers to the ledger board. Rest one end of each side beam in the double joist hangers and prop them up until level with a stack of wood.

Some Steps On How To Attach A Patio Roof To An Existing House

Pin on Dream Home

Attaching a patio roof to an existing house is not a doddle, but it does not mean that you cannot do it. You just need some assistances of experts if you are not really good at carpentry.

Before attaching a patio roof to your home, you need to prepare some materials such as:

  • Nail gun
  • Ledger

Steps:

  • Measure the sightline clearance height from the roof to the house, not the other way around.
  • Measure the size of the beam that you are going to use.
  • You can either remove the eave or just keep it.
  • Using lag bolts and a screwdriver, fasten the base of the posts to the ground. You have to make sure that they sit plumb.
  • Make a cutting on one of the sides of the horizontal roof beam on an angle. You have to do it thoroughly so that the rafters sit flush on it.
  • Attach the horizontal beam by using a nail gun. After that, to make it flush with the roof of the existing house, cut the two outer rafters.
  • Now you can begin assembling the outer rafters and attaching the rafter beam to the edge of the roof of the house.
  • Cut each of the house ends while continuing installing the rafters so that they fit the top of the rafter beam perfectly.
  • When all the rafters are installed correctly, form your patio roof by attaching the planks horizontally across the rafters.
  • If you are going to use shingles to cover the patio roof, do not forget to install black roofing felt along with a single layer of oriented strand board. When they are installed, you can begin attaching roofing shingles.

Most Common Ways To Attach A Patio Roof To An Existing House

Attaching a patio roof entails intermediate carpentry skills and creativity because there are many ways that you can choose from.

All of them have their own advantages and drawbacks. When installed correctly, the patio roof will complement the house and provide an extra entertainment for you and your family for all year round.

Here are 7 different ways of attaching a patio roof to an existing house that you can apply.

Rather Watch Us Build Our New Patio Check It Out On Youtube

So let’s start from the beginning with the design. My husband wanted the biggest deepest patio we could get with unobstructed views. Our current patio was 30’ long and that length was good so that we didn’t cover the windows to two of our bedrooms. Our house is already on the darker side and we wanted to keep as much natural light inside as possible. So we knew 30’ long, but how were we going to that big of a span without posts in the middle? I didn’t think it was possible, but my husband wouldn’t give up on it. So I went and talked to an architect friend and he said it would be possible with an 18” glulam. He also suggested adding another set of posts close to the outside that wouldn’t block any views but would help balance the look. I totally agreed and is one of our favorite features. He also said we could get away with smaller joists, but because we were leaving them exposed, I went with 3×8’s to again balance the look. As far as the depth, we settled on 14’ so that we could use standard 16’ joists rather than having to up the joist size to 20’ and then cut them down to size.

Next up was #DemoDay! It was sure nice to see the old patio go down and that meant things were getting real! I did salvage the wood and made a dining table for the new patio. If you haven’t seen that build, you can check it out here. It is a real conversation piece when I tell people what I made it from.

The following week I did more sanding and clear coated all the wood using .

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.

Cut Away The Overhang And Siding To Make Way For The Porch

You’ll have to decide whether to cut a slot where the porch walls meet the siding. If your siding is stucco, brick or stone, you may want to butt the walls to the siding.

Make a mark 1-5/8 in. out from the deck on both sides. Then make another mark 5-1/8 in. inside the first mark. Draw plumb lines up from these marks and cut a 5-1/8-in. slot through the siding but not the sheathing. Set the saw blade just deep enough to cut through the siding only. Remove the siding. Waterproof the slot with No. 15 building paper.

Attached Or Freestanding: Different Requirements For Each

If your patio cover is attached to a house or structure, in most cases, you can often attach posts to existing concrete footings. However, if you plan to install a freestanding pergola, the code requires you to dig concrete footings to ensure stable support. You won’t be able to attach your posts directly to an existing concrete slab.

Method 1 Of 2:installing Different Types Of Patio Covers

  • 1Purchase a patio umbrella for a cheap premade option that is easy to set up. This is the most basic and economic option to cover your patio. Get a patio umbrella that fits on your patio and is mobile so you can adjust it to block the sun as it moves, or shelter against light rain.XResearch source
  • An advantage of patio umbrellas is that you can include them as part of an outdoor furniture set to complete your patio decor.
  • 2Use some poles and a tarp or canvas to create an affordable outdoor canopy. Cover your patio with a tarp attached to 4 poles if it is located away from your home. Use only 2 poles and a tarp attached to the wall of your home .XResearch source
  • Get a tarp or canvas that already has grommets in the corners to easily tie it to the poles. Use a sturdy cord to tie everything together.
  • You can use ropes and stakes, or buckets weighed down with sand or water, to secure the canopy in place. Stakes anchor the ropes that support the canopy’s poles in place, or buckets act as weights to hold the rope and poles in place.
  • 3Buy a sail shade and tie it above your patio with the provided accessories. Look for secure points you can tie the sail shade to such as posts, trees, or secure parts of your home. Install wooden or steel posts at the corners of your patio if there are not enough existing points to tie the sail shade to.XResearch source
  • If you do attach the sail shade to trees, this should be for temporary use only so you don’t damage the trees.
  • How To Build A Patio Cover With A Corrugated Metal Roof

    Learn the basics of building a patio cover with a corrugated metal roof. 

    One of the simplest and most affordable ways to add some shade and cover to your outdoor space.

    One of the most basic and cost effective ways to create a great shady covered area for your patio space is a patio cover made with a corrugated metal roof.

    The corrugated metal is inexpensive to purchase, lightweight to install, and provides a sturdy way to keep both the rain and hot sun off your patio.

    The corrugations naturally channel the water downward along the slope of the roof either into a gutter or into the landscaping, much in the same way a sloped patio channels water away from your foundation.

     

    Tips For Joining The Screened In Porch And House Roofs

    Patio Pros

    If you’re not sure how to neatly join the screened in porch and house roofs:

    • We recommend hiring an architect to help work out the details.
    • Another option is to build a full-size mockup of a roof truss out of inexpensive and lightweight 1x4s. Figure out where the top of the wall plate would be if you built the porch according to our plans . Then support the mocked-up truss at this height to see how the porch overhang meets the roof.
    • If you don’t like the way the overhangs intersect, adjust the level of the deck slightly, alter the wall height or change the width of the overhang.
    • Contact your local building inspections department to find out what’s required to obtain a building permit.
    • Start this process at least a month before you plan to build. This will allow enough time to work through potential problems.

    Step 2: Choose A Material And Make A List Of Supplies

    https://storage.needpix.com/rsynced_images/house-3346909_1280.jpg

    If this is the first time you have built a larger structure, you may want to hire some help or watch some instructional videos before you begin. Regardless of your experience level, it is helpful to follow a set of step by step instructions on how to build a freestanding patio cover.

    It is also important to have the right materials before you start building. You will need to purchase items like quick-dry cement and bolts and pressure treated boards. If you go to your local hardware store they can help guide you on what to purchase before you begin.

    You will need basic tools like a drill and screwdriver. You will also need a circular saw, but you can rent those instead of spending the money to only use it once.

    A Freestanding Patio Tends To Be Easier To Install

    Attaching the cover of your patio on the roof of your house can be arduous and harmful. If the structure of the roof is not strong enough, it cannot support the cover.

    Unlike the ones that rely on the roof of a house, a freestanding patio is stronger and safer because it is supported by four posts that do not rely on any other buildings.

    Method 2 Galvanized Post Brackets Set In Concrete

    • Dig post holes 300mm square by 600mm deep.
    • Fill the holes with concrete and set the brackets in position while the concrete is still soft.
    • Ensure the brackets are at the right height, taking the finished slab into consideration. Some temporary packing, props or bracing may be needed to support the brackets until the concrete stiffens up.
    • Wait until the concrete has cured and then install the posts plumb in the brackets and hold in place with temporary bracing.

    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.

    Freestanding Patio Cover With Traditional Accent

    This patio provides a bit traditional accent to your backyard. It is like the ones that you can encounter in Bali.

    The stained wooden posts give a more natural and impressive look to the patio. The exposed beam ceiling makes the patio look more attractive although it does not feature sophisticated patterns.

    The black roof shingle plays an important role in creating the traditional ambiance. It suits the chairs perfectly.

    Since the roof slopes down from the center, it does not accumulate water, snow, and leaves which makes it easier to clean.

    Attached Patio Roof Vs Free Standing Patio Cover

    A freestanding patio cover is still a big project, but it’s usually easier to build than a patio roof that attaches to your house. In general, retrofitting anything onto anything brings up problems. Whenever possible, it’s pretty much always better to put new things onto other new things.

    And so, if any significant portion of your patio’s square footage is at least a few yards away from your house, a freestanding patio cover will probably be your best bet, at least when it comes to construction. Maybe when it comes to using it, too–there’s a certain feeling of luxury that comes up when you walk from the domain of inside your home to the outdoors and then into another protected, not to mention beautiful, area which is still outdoors.

    In fact, a freestanding patio cover affords virtually unlimited style options. By contrast, a patio roof attached to your house depends largely on what’s going on with your siding and existing roof. This is true both in terms of technicals and style. Whereas any freestanding patio cover can look natural away from the house, one that grows directly out of the side of the house but deviates from the house’s color scheme, shingle and siding style can look strange and awkward.

    Prevent The Splash Of The Rain Let The Air Flow

    The ultimate goal of installing a patio roof is to protect you from the rain and the glare of the sunlight. Unfortunately, it requires you to block the air flow sometimes.

    To prevent the splash of the rain, but let the air flow, you need to place the patio sheeting over the top of the roof about 300 millimeters so that it can perform shield from the rain without blocking the airflow.

    It is your best bet especially if you have a fully-covered patio which do not have much airflow.

    How To Attach A Patio Roof To An Existing House

    Honestly, there is no easy technique for how to attach a patio roof to an existing house. It’s not really one of those home-improvement jobs that tend to work well as  DIY projects. In a sense, you’re sort of building half the frame of a smaller house, against your house. It’s a medium carpentry job with a large side of roofing.

    Investing in the required suite of power tools alone–cordless drill, circular saw, nail gun and the like–will eat into the savings you get from doing the work yourself. You also may need permits–frankly, you probably will. Contractors work with permits every day and know what to look for, who to talk to, and what’s needed. An independent homeowner who’s not familiar with the process, however, stands a good chance of missing a permit that they need, and cities don’t like to cut they-didn’t-know slack for that.

    There are plenty of articles and YouTube videos online that provide a good introduction to the basics of how to attach a patio roof to your house . Take a look at them; if it looks similar enough to other carpentry projects you’ve done in the past, feel free to give it a try. If you have any hesitation or second-guess your skills, call experienced Denver roofers to help.

    Getting A Building Permit For Your Patio Cover

    “It’s just a simple patio cover with a corrugated metal roof…I don’t need a permit right?”

    Wrong.

    A building permit is legally required if you want to put together a patio cover, or any permanent outdoor structure on your property for that matter.

    It is another step to make sure everything is done safely and it gives your town a record of the work you’re doing.

    A permit doesn’t raise your taxes nor does it require a licensed contractor to apply for.

    Take your drawings and plans to your local permit and licensing office. They’ll have some papers for you to fill out and a small fee to pay .

    Many times you can find these online at your county or city’s website and fill them out ahead of time.

    A building inspector and structural expert will review the plans and your current structure.

    They’ll make recommendations and finally stamp your drawings. Only with a stamp can you start building.

    If you start building without a permit and an inspector drives by or a neighbor calls it in, the county can come make you tear the whole thing down and charge you a hefty fine on top of it.

    So better to get your paperwork in order beforehand.

     

    Frame The Walls Accurately For Smooth Assembly

    Since the wall framing for this screened in porch is the finished surface, it’s worth taking a little extra time to make the framing material look good. We chose the nicest cedar 2x6s we could find and ripped them into 3-1/2-in. and 1-1/2-in. boards. We did this to create sharp, clean edges .

    Cut the studs and crosspieces to length and screw the walls together . We used a power miter saw for clean, square cuts, but a circular saw will work too. Use a crosspiece as a spacer when you’re attaching the studs to the top and bottom plates. Then cut a 10-in. spacer block to position the crosspieces for assembly.

    Construct A Jig To Assemble The Roof Trusses

    Prime Before Painting. 

    Prime and paint the truss parts, wall frame and screen stops before assembly. Prime the wood with a special stain-blocking primer such as Zinsser’s oil-based Cover-Stain. Then brush on a coat of acrylic exterior house paint. Make sure to prime every cut end as you work; otherwise, these areas will absorb moisture and cause staining. We prefinished the roof boards with an oil finish .

    How to construct the roof truss jig: 

    It’s easiest to assemble the roof trusses first, using the deck platform as a work surface. Screw two sheets of plywood to the decking and use the dimensions in Figure J to chalk lines indicating the top of the rafters and the bottom of the 2×6 crosstie. Cut triangular blocks and screw them to the plywood to hold the rafters in alignment as you assemble the trusses.

    Getting A Building Permit For A Patio Cover

    Some people said a building permit was unnecessary, while others said it was impossible to get without a contractor’s license, or that it would raise my property tax, etc. So I called the permit and licensing office and got the correct answers.

    • Yes, a permit was required.
    • No, it wouldn’t raise my taxes,
    • As long as the property owner didn’t care if I wasn’t a licensed contractor, they didn’t either.

    Getting the building permit was actually much easier than I thought. I took the plans to the town’s permit and licensing office, filled out some paperwork, and the next morning I got a call and went back to the permit office to pick up and pay for the permit, which came to $85. They made a couple of alterations to the plan that not only were easy to accommodate but also made the project easier and cheaper! To prepare for the final inspection, I took pictures of each critical step to show the building inspector, which made the final inspection a snap.

    Building Permit

    Install Some Riser Brackets For More Height

    If you wish to reach a specific height, you can lift the roof of the patio with some riser brackets. The patio roof which is raised with some brackets requires a custom barge cap.

    It will not only allow you to raise the ceiling up to 2 feet, but also give various splendid options for the finishing look and relaxed ambiance.

    You can go with opaque twin wall sheeting if you want to get some natural light for your patio.

    Opaque twin wall sheeting that is installed between the roof of the patio and the barge cap allows natural light to pass through.

    If you are not really into natural light and want to block it, you can infill the gap between the patio roof and barge cap, and seal the rear opening.

    To get a cleaner and nicer look, you can add some extra flashing wall covering. After that, you can seal the brackets from the front.

    Method 2 Of 2:building A Wooden Patio Cover

    Free Standing Patio Cover Plans

  • 1Measure your patio and determine how high the patio cover will be. Use a tape measure to check the length and width of the patio you want to cover. Decide if you will create a free-standing cover or if you will attach it to your home at one side. Measure the height of the edge of the roof of your home if you will attach it there.XResearch source
  • The patio cover can be any height you want if you are going to make a free-standing structure, but at least 7 ft is a good standard height. If you are going to attach it to the edge of the roof of your home, then it will need to be lower than the gutters of the home’s roof.
  • 2Install post mounts in each corner of the patio. Get 1 post mount for each corner, such as 6×6 post mounts, from a home improvement center or hardware store. Bolt them squarely into each corner of the patio where you will install a post.XResearch source
  • Depending how big your patio cover will be, you can use smaller or larger posts. Ask at your local lumber yard what size of posts you should be using based on your patio dimensions to support the load of the cover.
  • 3Cut the corner posts to the height of the patio cover that you want. Use a saw to cut the ends of the posts off to make them the height that you determined for your patio cover. Get the posts pre-cut to the size you need at a lumber yard or home improvement center if you don’t want to cut them yourself.XResearch source
  • Tongue And Groove Freestanding Patio Cover

    This patio is such a great place to spend your afternoon. It can also make a great living room in which you can invite your friends and colleagues to come over for some tea or coffee.

    Each post features natural stones that complement the fireplace as well as accentuating the patio.

    The tongue-and-groove ceiling creates an epic finish look. Each of the roof sides has a glass window that allows natural light to pass through.

    Pros:

    • Natural stones around each post are the icing on the cake.
    • The tongue-and-groove ceiling makes the patio look more attractive.

    Con:

    • Installing tongue-and-groove ceiling can be arduous and take a lot of time.

    Selecting Materials To Build A Patio Cover

    While looks are important, you want to make sure that the materials fit the structure. Since my patio cover was going to have a slight slope, shingles were out. A tar roof would work, but it would be a heavy smell like a BP oil spill. I decided on corrugated metal roofing because it’s resistant to high winds, is lightweight, and is structurally sound.

    Using corrugated metal also allows me to reduce the degree of slope, or roof pitch needed to a mere 10 percent, or a 1-to-10 pitch. This meant the patio cover could start at the edge of the house’s roof at a height of eight feet and slope down to seven feet, leaving a clearance of more than six and a half feet between the lowest part of the frame’s headers and the ground at its outer edge.

    Full Protection From The Sun Snow And Rain

    If you are looking for something that can give you the ultimate protection from the heat of the sun, rain, and snow, you need to take metal roofing to your consideration.

    This metal roofing suits the style of the house very much. Besides accentuating the house, it gives you the protection that you need as it is attached directly to the wall.

    Plan Ahead To Avoid Construction Headaches

    You can add this screened in porch to almost any house, but attachment details may vary from what we show here.

    • On most two-story houses, you won’t have to worry about tying into the roof, but you may have to situate the porch carefully to avoid covering a window.
    • The house roof sloped 5 in. per foot and extended 18 in. at the overhang. Your roof may vary from this, and the details of how the porch ties in will vary as well.

    These illustrations above show the plans for the screened in porch, deck framing, gable framing, ledger, truss block, side walls and the end wall. To print these how to build a porch plan, see Additional Information at the end of this story.
