Roofing a one way sloping back porch.

Hip roof construction is one of the most popular methods used for both porch and screen porches. To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. A roof that slopes in only one direction is called a shed or pent style. Put down your first sheet of plywood at the corner of one end of the roof.

Make a cutting on one of the sides of the horizontal roof beam on an angle. Once completed roofing paper will be installed. Drive a nail into each corner of the plywood to hold it in place temporarily. Make sure it s lying horizontally across the exposed rafters and that the edges are flush with the edges of the end rafters.

It is a common roof on sheds and other outbuildings and is frequently used on carports patios porches and small additions to a house. Hip roofs are sloped from each wall and do not have the gable ends. Determine the minimum slope of the roof based on the roofing material. Then attach drip edge over the roofing paper.

You have to do it thoroughly so that the rafters sit flush on it. Sheathing 1 2 inch plywood or osb is nailed to the rafters. It also is often used on dormers extensions built on a basic roof to provide more light or space inside. Apply a 2 inch wide layer of roofing cement across the top of the first row of roofing.

Hip roofs allow for extended depth. Attach the horizontal beam by using a nail gun. After that to make it flush with the roof of the existing house cut the two outer rafters. After installing the rafters we still had to extend the porch roof back over the shed roof creating a valley on either side.

When building a porch roof asphalt shingles or other roofing material are then attached over the roofing paper and drip edge.
