How to Attach a Porch Roof to a Mobile Home

A porch roof is attached to the front of a mobile home as it provides an opening for people to enter and exit the house. A porch roof can be made from metal, wood, or plastic. When deciding on material, consider what will go on top of this area, such as a deck or patio. 

How To Attach A Porch Roof To A Mobile Home

If you are installing a new porch roof, make sure that the measurements are correct so that they match up with your mobile home structure. This way, there are no gaps between the two structures that could allow rainwater during inclement weather conditions. You may also want to install flashing around pipes near where the two structures meet. It is important to know how to attach a porch roof to a mobile home.

What You’ll Need

  1. Screwdriver
  2. Drill
  3. Tape measure
  4. Level
  5. Pencil
  6. Circular saw
  7.  Circular saw blades

Here Are the Step by Step Instructions for How to Attach a Porch Roof to a Mobile Home

Step One: Build the Frame

The frame of your mobile home porch will be constructed from 2×2 lumber. The pieces should measure 12 feet in length and be cut at a 15-degree angle on both ends, or 3-1/2 inches across the bottom and 5 inches across the top when assembled. To achieve this, I used three studs to run the length of the frame, then cut a piece 4 feet long and attached it at a 90-degree angle to one end of the studs.

Build the Frame

This will create three sides that meet in the middle to form an upside-down V shape. For attaching the frame together, you’ll use 1/2 inch bolts with 3/4 inch washers and wing nuts. The length of the bolts should be around 2 1/2 inches, but measure to make sure they’re not too long.

Step Two: Attach the Frame to the Mobile Home

Once you’ve assembled your frame, attach it to your mobile home by drilling through the bottom of the frame into the subfloor running below your mobile home.

If you can’t drill into the subfloor, attach it to your trailer’s header by drilling through one of the studs and connecting it with a couple of 3-inch nails. The nails should break off easily if you need to take down the porch for any reason later on, but they should be strong enough to help support the weight of the porch.

Step Three: Attach the Roof Trusses

Using your carpenter’s square, mark the angle at which you’ll need to cut each end of all four boards to assemble them into a square. Once they’re cut at the proper angle, attach them using 2-1/2 inch screws. Then, stand back and make sure that it’s square before continuing.

Once you have your trusses assembled correctly, lay them flat on their side attached to your angled frame so that one end aligns with the point where the roof overhang will begin. Trace the shape of your trusses on the side of your frame, then measure the distance between where they are currently attached to where you need them to be. Next, cut two pieces of treated 2×4 lumber at this length and connect them using screws or nails to the outside part of your sub-frame.

Attach the Frame  To the Mobile Home

Continue this process until all four trusses are attached. Then, attach the other side of your truss to where you marked on your mobile home. Then, you can either attach it with nails or screws that break off easily or use bolts and washers like you did to attach the porch frame itself.

Step Four: Put Up the Walls

Now that everything is in place, you can start putting up the walls. First, cut twelve 2×4 pieces at 16 inches and attach them to your porch frame by screwing or nailing them into place, as shown above. If you’re wondering, this is a standard stud spacing that won’t be affected if your building shrinks or swells with temperature changes since it’s attached to a frame that is already screwed into the walls of your mobile home.

Once you’ve attached them, use a carpenter’s level to check and see if they’re plumb in relation to each other before attaching additional 2×4 slats from your scrap pile at 24 inches apart. Finally, attach these with nails or screws so that when your porch is ready for use, you’ll be able to attach the roof to the walls just as you would any other building.

Step Five: Add Some Trim

Enclose your porch with some trim by first cutting a piece to fit along the top of your porch and then using it as a template to cut similar pieces at 2-foot intervals. When cutting corners, cut 1/4 inch off to give your porch a more finished look and prevent splitting.

Add Some Trim

Attach your trim boards with nails or screws at the top and bottom of each board so that you’ll be able to secure it flush against one of the walls when you finally put it on your roof.

Step Six: Attach Your Porch

Now that your porch is enclosed except for the roof, you can attach it to your mobile home. But first, you need to account for the included overhang on each side of your porch so that it doesn’t interfere with the walls of your mobile home.

To do this, place a scrap 2×4 against the bottom of your wall to angle it out, then cut a piece of trim to fit snugly against the 2×4 and the top of your wallboard. Attach this piece to both the wall and 2×4 before attaching them as a unit directly beneath each corner of your porch roof.

Step Seven: Work on Your Roof Frame

Now that you have a frame for your porch roof, it’s time to put up the rafters. You can cut them yourself or buy precut 2x4s at your local home improvement store. If you decide to cut them yourself, space each rafter 24 inches apart and attach beams in between each one so that there are three rafters and two beams in total.

The purpose of this step is to reduce the amount of material your roof trusses will have to carry so that they can do their job better and last longer. It’s a balancing act between cost, quality, and longevity with every decision you make when building this type of structure, so keep that in mind when you’re building your porch roof.

Should You Attach a Deck to a Mobile Home?

If you add a deck to your mobile home, decide whether it will add value to the home or just add space that must be cleaned and maintained. You’ll have to attach the deck securely with metal brackets, which requires cutting into the floor pan of your home. If done well, this can help hold up a mobile home in a hurricane.  If done poorly, the floors will cave in.

When Hurricane Charley hit Florida in 2004, many mobile homes were destroyed because their decks had not been securely attached to the home. Some did survive, however, because homeowners had attached decks that held up during the storm. Adding an attachment to your mobile home requires you to attach it securely with metal brackets.

If the hurricane is powerful enough, this could help hold up your mobile home in place. In addition, decking creates outdoor space for porches and patios, which increases the value of your property. If you want a porch on your mobile home but don’t want to build it from scratch, attaching a deck is an easier option than adding one built from the ground up.

How Much Support Does a Porch Roof Need?

The porches on manufactured homes are usually much smaller than you would find on a site-built home because the homeowner has less room to work with. And since they can’t be as big, manufacturers often slope their roofs down over the porch, so the homeowners have at least some shelter from rain and snow. But if your mobile home has a sloped porch roof, don’t assume it’s strong enough to keep the weather out.

Typically, the only thing that runs along the peak of a sloping roof on a mobile home is hanger wire for hanging plants. That means your porch roof probably won’t be held down by anything more than gravity. If you have a lot of wind up in your area, or there is a big drop-off that leads straight to the porch roof, you might want to attach your porch roof for extra support.

Frequently Asked Question

Can I Attach a Porch Roof to a Mobile Home?

The best way to attach a porch roof to a mobile home is with the help of some heavy-duty screws.

One of the most important steps in installing a porch roof on your mobile home is ensuring that you have removed all windows and doors from the side or back of your home before attaching them. You can do this by using plywood, sheets of metal, or other materials to cover up these openings.

Once you have completed this step, use a drill and screwdriver to drive screws into the framework at an angle that will be parallel with the decking on your trailer’s frame. Use galvanized nails to secure these screws in place as well as any other additional fasteners such as anchors and bolts.

What Holds a Porch Roof Up?

A porch roof is held up by a rafter. The rafter is the horizontal beam that spans across the length of the porch roof and supports the weight of its roof.

Should a Deck Be Attached to a Mobile Home?

There are some advantages and disadvantages of having a deck attached to your mobile home.

The main advantage of having a deck attached to your mobile home is that it provides extra space for storage, and it helps keep the floor space in the house clean, neat, and tidy. It also gives you more places to sit and relax when you’re inside the house.

However, there are some disadvantages as well, such as it increases your cost of living if you have to maintain the deck because it requires regular cleaning. You will also need additional lumber, which could make this option more expensive than other options available for you.

How Do You Support a Porch Roof Without Posts?

There are many ways to support a porch roof without posts.

  1. You can use wood, bricks, or metal brackets to support the rafters.
  2. You can install trusses between the rafters and supports for more stability.
  3. You can build a wall on the perimeter of your porch roof and attach it to your walls with screws or nails so that it doesn’t move or wobble when you walk on it.


Attaching a porch roof to your mobile home is not as difficult as it may seem. The process can be done in just two steps, and you should have all the materials needed to complete the project at hand. To start, you will need to measure out where on top of your mobile home that you want for your porch roof’s gable end.

Next, use some wood screws or nails and shims if necessary, so that horizontal boards connect across the ridge pole between both ends of the roofs.

Finally, attach either V-shaped rafters or diagonal braces from one side of each pair of adjacent boards up over their opposite board towards the other side, forming an “X” shape while also running them along the ridge and down to the gable’s bottom on both sides.
