Your plans on building a sunroom patio enclosure can be simple or complex depending on your expectations. You can use an existing deck space as the flooring for your new room. This will make the process much easier. You will only have to build in the walls and roofing system. This home improvement project will probably take you a couple of days to complete. Be sure to check the forecast for a few days of good weather.
Step 1 – Making Preparations
Check with your local building code office for any rules and regulations about constructing your sunroom. Check to see whether you will need any permits. Use your tape measure to determine the space on your deck for the sunroom. Determine the number of windows you want.
Step 2 – Creating a Ledger Board
You will need to build a ledger board on the exterior wall of your home. The ledger board will be installed where the roof of the sunroom will meet with the house. Your board should be 2 inches by 10 inches. Secure it to the board with bolts. Attach several joist hangers to your board. Install them at 16-inch intervals along the ledger board.
Step 3 – Framing the Sunroom
Secure columns to your exterior wall. The columns should be four-inch-by-four-inch posts. Use nails to attach them to the wall where you want to connect the side walls of the sunroom. Use your lumber to frame the three walls to the sunroom that need to be built. Be sure your frame allows for window space. Use two-inch-by-10 inch posts as the top piece of wood on the three walls.
Step 4 – Installing the Roof Supports
Secure a triangular support across two of your sunroom walls. The support should match the roof pitch you want to create.
Step 5 – Installing the Sunroom Walls
Secure the three walls to your sunroom with nails. Attach the walls to the exterior wall of the house and the decking. Be sure your walls are installed properly. They should be both level and plumb. If they are not, make the necessary adjustments to correct this problem. Attach the last wall to the two side walls. Be sure it is plum and level as well. Secure joist hangers to the top of the front wall.
Step 6 – Finishing the Sunroom Walls
Use nails to secure the ceiling joist on the joist hangers. Secure plywood to the exterior of the sunroom and the roof. If you prefer, you can also secure the plywood to the floor of the sunroom. Install the windows and door to your new room. Be sure they are positioned properly.
Step 7 – Finishing the Sunroom Exterior
Secure siding to the exterior walls of your sunroom. Be sure to use a product that works well with your home. Secure tar paper to the roof plywood. Use roofing nails to attach the shingles over the tar paper.
