Porch Framing Details

With more people wanting a porch to enjoy on mild days, more homeowners are installing porches on homes that were not originally built with them. The biggest part of building a porch is doing the framing. Porch framing details can make the job complicated, but it is still a task that can be completed without a professional builder if you make an effective plan.

Before beginning the framing, figure out the details before any lumber is purchased. This will include coming up with a plan that details the shape and size of the porch, as well as it’s height off the ground.

The right spot should be found on a home as well, that will give the porch the most useable space. Porch framing details such as the style of porch and what type of wood will be used are also considerations. Other details may be the angles involved in the plan to capitalize of the movements of the sun.

If the porch is to be enclosed with windows or screens, or there is a plan to do so in the future, that should be taken into account when framing the porch. Planning for these porch framing details can save a lot of hassle and labor down the road.

Framing in the Details

Framing a porch is shouldn’t be a long project unless the porch in question is unusually large. Using chalk to make marks to guide the layout can save time when the framing has begun. Making sure that the right amount and size lumber has been bought is another big time saver.

But once the porch is laid out ands the lumber has arrived, the porch will begin to take shape quickly. The bulk of the work may actually be in the porch framing details. If there are to be soffits, decorative wood details, or elaborate railings, those will be the time consuming elements. There is also a matter of the door sills being adjusted, and building a new door if the porch is to be enclosed.

The porch is formed on one side by the wall of the house, leaving only the floor, railings and supports to be framed. Some porches will also have a roof over them, which will be supported by posts or columns. Many porches rely instead on a roof overhang from the main roof of the house.


Adding a roof onto a porch may add a good deal more time to the project, depending on how elaborately the roof design is. The porch framing details needed when a new roof is to be built may be much more elaborate than if the porch relied on an overhang.

Porch roofs may have decorative woodworking around the edges, or they may be supported by highly styled columns. Framing the roof of a porch is highly exacting work as well. The roof line should closely match or compliment the main roof of the house.

The porch roof, in addition to matching the style of the house, should also be framed with an eye toward the climate in the area. If the area can expect heavy rain or snowfalls, a more sloped roof will be needed.

In very dry areas, a flat roof is acceptable for both a house and a porch roof. The style and slope of the roof will lend itself to more possibilities for decorative porch framing details.
