- Take a screwdriver and lag bolts to fasten the base of the roof posts to the ground.
- Trim one side of the horizontal roof beams at an angle carefully to make sure the rafters sit flush on it later.
- Use a nail gun to connect the horizontal beam. Then, set it flush with the roof of your existing house.

How to Connect a Porch Roof to a House in Five Different Ways
You just need to ensure that you take the right way to attach your patio roof since they come with their own pros and cons.
For your reference, here are a few different methods to connect a porch roof to an existing house that you can pick.
1. Use riser brackets
To achieve a particular height, you can take advantage of some riser brackets. Then, these will require a customized barge cap to lift the roof of your patio.
Further, utilizing riser brackets let you elevate the ceiling up to 2 ft. A bunch of striking choices for the calming ambiance and the finishing look are available as well.
If you wish to block natural light from pasting to the patio, consider filling the gap between the barge cap and the porch roof.
Then, seal the back opening to finish. However, if you prefer to get some natural light, opt for using opaque twin-wall sheeting.
Hence, installing this feature between the barge cap and the patio roof will allow more daylight to pass through.
You can also incorporate additional flashing wall covering to get a cleaner and more finished look. After that, seal the brackets from the facade accordingly.
2. Install to the fascia boards
This is one of the most common methods to connect a patio roof to an existing house.
To proceed with this technique, you should fix the backchannel to the fascia board by strengthening two rafters inside the covering.
While this method is pretty simple to perform, it does not let you adjust the height of your patio roof.
If you want to make the porch roof a bit higher, it is necessary to get rid of the existing house gutter. Thus, you can set the backchannel in an upper position.
Since you have the gutter removed, the use of transfer flashing from the house roof to the porch will be compulsory.
Furthermore, removing the house gutter typically lets you add up to 4 inches of extra height.
3. Elevate the roof by 20 inches
If you wish to elevate the porch roof up to 20 inches, it is necessary to remove the gutter, fascia, and eaves.
Then, trim the rafters back to the wall line for installation purposes.
Afterward, connect the backchannel to the rafter directly and strengthen it. This step will give you a clean finish as the patio roof can attach to the wall line perfectly.
However, applying transfer flashings on top is recommended to complement the look of your patio roof when proceeding with this method.
4. Attach the roof to the wall directly
If you want to have the cleanest look without too much effort, consider attaching the patio and the backchannel directly to the house wall.
Likewise, this method allows you to get better protection from the rain as well.
Additionally, to prevent the splash of the rain, sometimes you need to block the airflow too. If you cannot afford this situation, try to set the patio sheeting over the top of your patio roof.
Place the sheeting about 12 inches above the top of the roof to let the air flow without getting splashed by the rain.
Thus, this should be your best solution, particularly if your patio is fully covered and does not have much airflow.
5. Take advantage of FHS columns
Another good method to attach a porch roof to a house is by applying FHS columns on top of the existing wall.
Follow the column installation with setting and strengthening the patio to the rafters. Then, you must put the beam on top of the desired height.
After that, do not forget to install a customized box channel on the house and a personalized barge on top.
Please note that this method requires you to remove fascia, eaves, and gutter in advance. Moreover, you need to cut back the rafters as well to create a neat look and additional height.
