Oakland roofing provides Porch roof construction that can be as straightforward as erecting a shingled lean-to off the side of the house and supporting it with vertical columns. It’s not a difficult process, but it does entail heavy building materials, and it’s usually beneficial to have a helper on hand.

How to Determine whether a Wall Is Stable Porch Roof Angle

Generally, it is preferable to angle, or pitch, the porch roof. Flat porch roofs are more challenging to waterproof and have a higher risk of leaking. Pitch-down porch roofs aid with water drainage. To maximize aesthetic attractiveness, the angle of the porch roof should ideally match the angle of the house’s roofing.

Attached Porch Roof

The ledger board is a vital component of the porch roof. The ledger board makes use of the house’s strength to support the porch roof’s highest edge. The ledger board bears half of the weight of the porch roof. Water leaking is prevented by installing metal drip flashing between the porch roof and the house exterior.

Beams and Posts at the Header

If the ledger board provides support for half of the porch roof, the header beam and posts provide support for the remaining half. Vertical six-by-six support posts are firmly buried in concrete footers every eight feet. Parallel to but lower than the ledger board is the header beam.


The porch roof’s shingles provide the finishing touch. When feasible, the porch shingles should match the Oakland Roofers shingles on the home.


Glue the Ledger Board to the wall

Remove siding and sheathing from the home to reveal an 8-foot-long by the 5-1/2-inch-high length of band joist or structural framing. After drilling pilot holes, mount the two-by-six board to the house using the lag screws and washers and the ratchet wrench.

Complete the installation of the rafter hangers

Every 16 inches, screw the rafter hangers to the ledger board. Each side of the porch roof should have one rafter hanger.

Establish Support Posts

Dig two stakes into the ground opposite the ledger board to the depth necessary in your region. If your location freezes, the holes may need to be dug below the frost line. Each hole should be filled with approximately four inches of gravel. Install the six-by-six posts plumb in the concrete and allow them to set completely.

Punctuation in the Support Posts

Cut the support posts to the height necessary for the porch roof to have the proper pitch after measuring with the Speed Square.

Following that, a notch off the tops of the support posts with the circular saw and manual saw to accommodate the two-by-ten header beam. The dimensions of the notch should be 1-1/2 inches deep by 9-1/2 inches high.

Glue the Header Beam in Place

Drill pilot holes first, then secure the header beam to the support posts in the notches with lag screws and washers.

Arrange the Rafters

Install the two-by-six rafters, extending them to the top of the header beam from the rafter hangers. Nail the rafters into place using the rafter hanger holes. On the beam side, nail the rafters to the beam.

Nail the 1/2-inch external plywood to the rafters’ tops.

Fix the Shingles

Install the shingles on the roof of the porch. One shingle square will suffice to cover this roof. Begin at the lowest point on the porch roof. Install rows in ascending order until you reach the house’s side.

Attach the Drip Flashing to the connection between the porch roof and the house’s side wall using nails. Attach the drip flashing to the connection between the porch roof and the side of the house using nails.
