How To Attach A Patio Roof To A Brick House



Two Videos Cover The Design Questions And Construction Process Of A Post And Beam Patio Roof Structure

 

Video 1: Design a Roof extension over an existing patio

Existing patio is outside the dining room on the west side of the house. the patio is essentially unusable on a sunny afternoon in the summer.

This video looks at a couple of design options, including attaching the roof ledger below that of the existing eaves and setting the patio roof atop the existing roof.

The latter option was chosen because the low roof and roof beam would have blocked the view from the dining area. Did we say that the house is in Bozeman, MT, where the view is worth viewing?

Work from the view back, not from the house, out.

  • Calculate the sightline clearance height, about 6 feet, 2 inches, in this case.
  • Determine the beam size: 8 inches in this case.
  • Choose a roof pitch and roof structure

This places the new roof on top of the existing roof. The next question is what to do with the existing eave under the new roof: kick it or keep it?

To tie the design together, Peter chose to cut the rafter tails off the extend the exterior wall up to the underside of the new roof. As it turned out, the existing roof structure is a truss system, but they were able to contact the original truss manufacturer to verify that cutting the tails off would not jeopardize the structural integrity of the trusses. 

From the we-hope-this-is-obvious desk: Never alter engineered trusses without the approval of a licensed professional engineer. Ever.

The next design decision: material selection

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

How to Attach A Patio Roof to An Existing House and 10 ...

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.

What Youll Need To Attach A Patio Roof To An Existing House:

  • Wooden Beams
  • Ledger
  • Utility Knife
  • Beginning from the roof to the house , calculate the sightline clearance height.
  • After that, determine the beam size you’ll want to use.
  • Then, choose a roof pitch and roof structure.
  • Because you’re installing your roof on top of your existing roof, you’ll want to consider whether to remove the existing eave or keep it.
  • Next, determine how many beams, rafters, and roofing planks you’ll need for your design.
  • Stain your wood pieces to protect them from outdoor elements.
  • Then, fasten the post bases to the ground using lag bolts and a screwdriver and make sure they sit plumb.
  • Cut one side of the horizontal roof beam on an angle so that the rafters sit flush on it.
  • Using your nail gun, attach the horizontal beam and cut the two outer rafters to sit flush on top of the existing house roof.
  • Install the two outer rafters and attach a plain rafter beam to the very edge of the existing roof.
  • As you continue to install your rafters, cut the house end of each one so that it fits over top of the plain rafter beam.
  • Once all of the rafters are in place, attach your planks horizontally across the rafters to form your patio roof.
  • If you’re covering the patio roof with shingles that match your existing roof, install black roofing felt and a layer of oriented strand board.
  • After that, you can attach your roofing shingles.

    How To Attach A Ledger Board To A House For A Patio Cover

    Patio spaces are great for relaxing and spending time outdoors. However, the same cannot be said if your patio lacks a cover, as you’ll not be protected from the elements. A great way to improve your patio is by attaching a ledger board for a patio cover. Not only does it offer shelter from sunlight and rain, but it also adds aesthetic appeal and value to your home. It’s not a complicated process either to attach a ledger board to your house. 

    You will need to know what is required when attaching the ledger board to your house and how the entire process works, which you will learn if you read on. 

      Finding The Right Tools For Installing A Patio Roof

      Attaching a patio roof to an existing house is no easy job. It is doable, but it takes a lot of motivation and attention. Besides strong morale, you’ll also need the appropriate tools to get this project completed. Patio roofs can be dangerous if they are not installed properly, especially if the area in which you live in is known for harsh weather conditions that often cause roof damage. In order to avoid any risk and to keep yourself and the ones around you safe, make sure you use tools correctly. You’ll need:

      • Carpenter’s pencil to mark spots
      • Level
      • Ledger

      Attaching Porch Roof Or Pergola To Old Brick Home

      I just took apart a very badly made porch attached to an old brick house . I do not want to go into the details but the old porch was so badly built that it pulled apart some of the old brick which I then had to re-point!

      I now have a solid wall and I would like good advice on a sure way to attach to this old house. The brick wall is soft brick built with lime-putty then 1-inch space, black tar-paper then 12-inch boards nailed on top of 2×6 frame.

      My plan is:

      • To rest the roof of the structure onto a beam supported by two 6×6 posts on the house side
      • First doing proper footings below frost line then build a deck.
      • Then build a porch roof with 6×6 four-post structure with lean to metal roof or just a pergola for more light.

      Trying to cover lateral forces blowing from the west/east so what is the best & strongest way to attach the 6×6 posts against the brick house this old?

      Is there a better way?

      How Much Does It Cost To Build A Roof Over A Deck

      The cost to cover a deck will depend on a number of factors. These factors include the type of material, the size of the roof, and how complicated it will be to build. Currently, the cost to add a roof over your patio will start at $2,000 and increase from there. Contact a local roofing company to get started and schedule an estimate for your project.

      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 An Existing Brick House

      When you attach a patio roof to an existing house, you can create a patio look that flows from roof out. Creating this patio roof requires some woodworking knowledge and patients, but if you have the skills and time, you can make it work. Here, our roofing experts explain how to attach a patio roof to an existing house.

      Vertical End Beam And Rafters Checked For Level

      Attach the Rafters

      Attach 2×6 rafters to the house with joist hangers and/or supported by the ledger board. If necessary, use a sliding bevel to determine angles needed where the rafters will meet the ledger board. Rafters are placed on 24″ centers, and attached to the beams and settle joists are attached as needed . The rafters should be added from each end working toward the center. Check each rafter for level as they are installed. Attach to ledger first, then settle joists. The vertical end beam is checked for level as the end rafters are positioned and secured. If the rafters extend over a beam, do not extend more than 1/3 of overall rafter length.

      Attaching A Pergola To A House To Create A Wall

      A wall-leaning pergola offers lots of flexibility and versatility when it comes to size and location.

      I had a friend who wanted to build a pergola but didn’t quite have the room for a four-post structure. His entryway was pretty narrow and pergolas tend to be kind of wide. But that was ok. As I told him, the beauty of pergolas is in their flexibility. I suggested a two-post structure, with his house acting as the support for the post-less side. Attaching a pergola to a house can save a bit of space while providing the support the structure needs. With a few adjustments to the standard design, and the installation of a strong ledger board, your house can act as your pergola’s support.

      Traditionally, pergolas are four post structures, but as my friend learned, it’s also possible to work with two posts by using your home to support the other side of the structure. This is commonly called a wall-leaning pergola, and it’s an excellent option for the front of the house when you really want to create an entryway focal point. But this type of pergola also requires some special considerations, which we’ll examine below.

      How To Fix A Deck Attached Through Brick Veneer

      To the best of my knowledge, there are two ways of addressing this issue. The first is to make the deck free-standing. This requires adding a beam right next to the house to support this end of the deck. The trouble with this repair is that footings will need to be added next to the house, and they might not be easy to get right. Deck footings are supposed to be installed on undisturbed soil, but the soil right next to the home is ‘disturbed’.

      The other way to address this is to install new brackets made specifically for this condition. This bracket is the Brick Veneer Ledger Connector , made by Simpson Strong-Tie. It basically consists of a huge metal plate, a pair of extra-long lag screws, and a big threaded post that’s called a compression strut.

      The images below come directly from the installation manual.

      And here’s what you get with a single kit:

      The compression strut holds the brick away from the home, while the lag screws support the deck ledgerboard.

      This method of repair won’t work in every situation, but for homes that meet the minimum requirements, this would be a far simpler solution than making a deck freestanding. For more information on BVLZs, head on over to the Simpson Strong-Tie website.

      How To Build A Shed Roof Over My Existing Deck

      Unless you’re experienced in residential roofing construction, you probably don’t want to build the roof yourself. However, you might want to know the process of how it’s done. Take a look at our step-by-step guide for building a shed roof over your existing deck:

    • Step 1: Before you begin, make sure you’re matching the house roof pitch angle and overhang for your roof.
    • Step 2: Install post base connectors. These are used to attach the support posts to the frame of the deck. For a solid connection, you’ll have to make sure the frame has the appropriate blocking.
    • Step 3: Install the support posts to the post base connectors.
    • Step 4: Keep the support posts in place by installing temporary bracing. The tops of the support posts should be notched to hold the header beam.
    • Step 5: Install the header beams to the support posts. We recommend using thru bolts for a strong connection.
    • Step 6: Install the ledger board, which will support the rafters. You can install it by flashing and bolting in place to the house wall.
    • Step 7: Mark and cut your rafter angle to the roof pitch and then lay out your rafters. Nail the rafters in place to the ledger board.
    • Step 8: Attach the rafters to the header using framing nails.
    • Step 9: Create the subroof by installing the roof sheathing over the rafters.

      Placement Of Header Determines Level Of Roof

      Start With Ledger Board

      A ledger/header board is the first step if you are attaching the patio roof to an existing structure. The placement of the ledger/header determines the level of the roof, so be sure it is positioned at the correct height and is horizontal. When fastening ledger/header boards to wood, the ledger should be held securely with bolts through the wall or lag screws.

      How To Attach Ledger Board To Brick Building

      framing

      tryitmyself

      A friend has an existing two story porch attached to a brick building. The porch is old but the wood is still solid. The ledger board beneath the 2nd story floor is separating from the building, increasing in distance to about 1 1/2 in at maximum. The old style construction did not have the ledger boards attached directly to the building. The ledger board was connected to a beam coming out of a beam pocket.

      I was thinking that I could drill holes into the ledger board at about 2 foot increments. I would then use a hammer drill and masonry bit to drill into the brick. I would install some lag shields and lag screws and use them to slowly draw the ledger board back to the brick surface.

      Does this sound like it would work?

      I would appreciate comments or other suggestions. Keep it non-technical because I’m just a “weekender”.

      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.

      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.

      Patio Cover Attachment Through Brick Veneer

      vigilant1General Discussion

      Our house is brick veneer over standard 2×4 construction.  I want to add a small patio cover over a nerwly installed paver patio.  6×6 posts at the corners and a ledger board along the house supporting the top of the simple shed roof.

      I discussed the idea with an inspector at our  county Building Regulation department, he said it would fine to use 1/2? lag screws to attach the ledger board into each stud through the brick veneer.  I drew up the plans that way, and they were approved.

      Now I’m having second thoughts.  The inspector who looked at the pier holes sure didn’t like the idea of using the lag screws. His logic is sound:  The screws are cantilevered through the 1? air gap and the 4 inches of brick, plus the 1 1/2? ledger board. That’s a lot of bending load, and if/when the screws bend they’ll be resting on the brick.  Plus–how can you tighten up the bolts without risk of cracking the brick?

      Other info:

           Required snow load is 20 lbs/sf.

          The ledger board will be 24? below a 24? roof overhang, so it probably won’t see much water.

           The two posts are embedded in 12? diameter concrete piers that go down 32? . I’m counting on these to provide a lot of resistance to racking and other movement.

      Questions:

      1)  Should I stop worrying and just build the patio cover using the lag screws into the studs as approved by the county engineers?

      Thanks for any input or suggestions, even snide remarks.

      Can A Patio Cover Cause Damage To The House

      Normally, a patio cover is meant to add an aesthetic appeal to your home and also provide more outdoor space. However, if the person handling the patio cover project isn’t careful, they might end up misaligning the sloping roof, thus giving your house a bad look. 

      If the project requires part of the roof to be removed to expose the wall line, it’s best at this time to let the professionals handle it. There is also the issue of water drainage since such a project would require removing the gutter. This is why you will most likely need a permit to build a patio cover.

      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.

      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.

      Where The Patio Cover Attaches To The Roof

      Beginning Construction On The Patio Cover

      Early the next morning the materials arrived at my house. Once the materials were unloaded, I began carrying the ten-foot-long boards and corrugated metal sheets to the backyard, laying them out in a pattern to roughly match how they would be assembled.

      I also separated the corrugated metal sheets, wiped each one down with a light coat of vegetable oil, and then re-stacked them. This was something I had seen a neighbor do a long time ago when I was a child. I don’t know if it served any purpose other than making me feel better. It’s a step I probably could have skipped, but who was I to doubt the wisdom of the ancients?

      How Much Does Building A Patio Cover Cost

      On average, a simple patio cover will set you back $1000 minimum. However, the costs can escalate to $5000 if the project gets complicated, such as removing parts of the roof to attach a ledger. If you want more style and customized designs, you should also be prepared to dig deeper into your pockets. With that being said, you can significantly cut down the total cost if you handle the project by yourself.
