This guide demonstrates how to build a pitched roof porch in a small walk-out basement. The project includes framing, raising and installing the subfloor, creating an entryway, rough-ins for gas appliances, framing overhead cabinets, installing outlet boxes and switches with conduit, finishing top plates and vents, and painting. Pitched roof porches are a great way to expand any home. The pitched roof not only creates space and character, but also provides roominess that a flat roof doesn’t offer. The pitch of your roof will also determine how much snow it can hold, as well as how much water it lets in when it rains. This guide will walk you through the process of building a pitched roof porch step-by-step. Building a pitched roof porch can add value and usability to your home, but it is also more challenging than building a flat roof porch. Building a pitched roof requires an understanding of carpentry skills and materials, such as decking lumber, that are specific to the job. Because you will be working with traditional tools and materials, experience with carpentry beforehand is helpful but not required for this project.
A pitched roof porch can add a pop of style to any home, but it can also help keep the rain out during a storm. The process is fairly simple and only requires some basic carpentry skills and tools. All materials can be found at your local hardware store or home improvement center.
Step 1 – Reviewing the Roof Pitch
When you begin to design a pitched roof porch, it is important that you first understand the components involved. The pitch of your porch will determine where and how many windows can be placed on the structure. It also determines if there are any significant changes in elevation within the area as well as how far down from the top of each support column your joists must extend.
To calculate your roof’s pitch, use this formula:
Pitch = Rise over Run
This means that for every foot of rise (rise), there should be 12 times that length across (run). For example, if you have 5 feet of rise and 16 feet across then multiply these two numbers together to get 80 feet total length needed on each side or 160 feet total length needed altogether.

STEP 1 – Laying Out Stringers and Cutting the Decking Material
The first step in building a porch is to determine where you want your stringers to sit, then cut them to size using your circular saw equipped with a carbide blade (or possibly an even better one if you have it). Then mark off the locations of each stringer on the decking material and use your jigsaw or reciprocating saw to cut out each piece of decking.
STEP 2 – Installing Shingles
Next, remove any nails left in place from when they were originally installed and flip over all pieces, exposing their undersides as well as their grooves which will hold shingles later on down this page; also note how many rows of shingles there are in total (typically three or four), since this information might help with planning later on down this section too! Once done prepping everything else like we just did above make sure everything fits together nicely before contacting us again because there might be something wrong with either how we measured our measurements or how long it takes us taking into account any other factors such as weather conditions outside during construction time frame.
Step 3 – Laying Out the Stringer Blocks
The stringers are the main support for the porch so they should be laid out precisely and level. You will need to make sure that you space them correctly so that when you attach them together, they form a straight line at right angles to your door frame.
- The stringer blocks must be level with each other. They should also be spaced evenly apart so that when you attach them together, they form a straight line at right angles to your door frame.
If you don’t have enough room between walls or posts in which to place your stringers blocks (or if they aren’t all square), consider using some of these hacks:
- Use two pieces of 2×4 lumber (also known as “studs”) as spacers instead; one piece will go near the top of each side wall for added strength and stability; another piece goes in between posts/columns between walls (just make sure it doesn’t interfere with any plumbing).
- If there isn’t enough room between walls/posts because one wall is too close but there is plenty of room left over outside this narrow area—use some sort of makeshift structure like ladders or scaffolding if possible as long as it’s stable enough not collapse during construction work being done on top
Step 4 – Cleaning and Treating the Frame Work
The next step is to clean the frame work. This can be done with water, soap, detergent or bleach. The purpose of this step is to remove any dirt and other contaminants that could cause problems later in the build process. Generally speaking you will want to clean off any loose material from around the exterior of your porch, such as paint or rust. If there are areas where there might be oil or grease buildup then those should be cleaned off too to prevent corrosion in your finished porch structure.
To ensure all dirt has been removed from your frame work it may be necessary for you to wash down each component several times before moving on with building your project so make sure you have enough time available before starting this step.
Step 5 – Measuring and Cutting the Shingles
- Make sure your ladder is secure before you climb up.
- Measure the length of your roof, then the height and width.
- Check that your ladder is secure before climbing up it to measure for rafters or any other part of this project.
- A pitched roof has a slope of 2/12 or greater (in other words, for every 12 inches from top to bottom, there are two inches added). So if all four sides meet in a point at one end, you have a steeply sloping pitch; but if they don’t all meet at one side and instead form an angle somewhere else on the building, then that end doesn’t have as steep an angle; this makes it easier to build because you don’t have such big pieces to work with – but it means less protection against rainwater getting in.
Step 6 – Placing the Shingles
- Place the shingles.
Using a chalk line, mark and cut the first course of shingles to fit your roof. Use roof-hugging shingles that are the right size for your roof, and be sure to make sure that each piece of slate is straight and level before you place it on top of your last course.
Follow these instructions for success.
If you’re thinking of building a pitched roof porch on your home, follow these instructions for success:
- Be patient. You may be able to get the job done in a day or two, but it’s likely that it will take longer than expected. Set aside plenty of time to work on your project and give yourself a realistic completion date based on what has happened during past projects like this one.
- Be careful. Don’t rush through any part of this process without paying close attention to what you’re doing and why, because rushing can result in mistakes that will have to be fixed later on down the road after the project is finished—which means more money spent and more time spent working on something that should’ve been done correctly from the beginning.
- Be precise; make sure all measurements are exact so nothing gets cut too short or too long because then there won’t be enough material left over if anything needs replacing later down
- Final words
Don’t be afraid to build your own porch. While the task may seem daunting, if you follow these instructions you should have no problem. One of the benefits of building a porch is that you can customize it as much as you like. If you enjoy this project, take advantage of all these possibilities and build yourself a beautiful home with an even better porch.
