3. Determine how many rafters and beams you will need

It is critical to know how many beams and rafters you will require. After you’ve measured your house’s sightline clearance height, you should figure out how many beams and rafters you’ll need. Then, assemble the exterior rafters and proceed as follows.

Step 1

Create the rafter that you will need before attaching the ledger board to your house. It should be noted that the ledger should be nailed to a strong section of your house, such as second-floor joists, using a nail gun.

The ledger is mounted horizontally and should be attached at a proper height because it will define the height of your patio roof. Make sure the leger board is securely fastened with bolts or lag screws.

Step 2

After you’ve correctly installed your ledger board, go to the flashing. The flashing is vital because it prevents water from penetrating behind the ledger board. The greatest Z-flashing is made of aluminum or galvanized metal.

This step is sometimes forgotten when installing a patio roof to an existing house, so don’t skip it; it’s critical. The flashing should be tucked beneath and curved over the ledger; it sounds like a difficult chore. Instead of having to bend your flashing, you can buy an L- or Z-shaped flashing.

Step 3

Paint the rafters you prepared previously in the color of your choice and secure the rafter to the ledger board using the joist hanger. Consider utilizing a metal joist hanger to provide a sturdy connection.

While alternative connections, such as seismic anchors, can be used to connect the top of your ledger to the rafter, the metal joist hanger is the best option and is easier to install.

A 2 by 6 is the most typical rafter; use a sliding angle to ensure that the rafters meet the ledger board at the perfect angle. After installation, ensure that every rafter is level and that the rafters’ ends are straight. It is typical to have a crooked rafter end, especially if your wall is crooked, but it is fixed by moving the rafter or trimming them with a saw.
