Framing A Lean To Roof With Overhang
12 x24 lean to roof plan.
Framing a lean to roof with overhang. A lean to roof just means it s attached to an existing structure. Fastening to masonry walls. Drill holes for the expanding anchors every 16 inches or as specified by local codes insert the anchors hold the ledger in place and tap it with a hammer to indent the anchor locations on its back face. If you build your own the cost will be about half this amount.
Because this style of a shed has a flat roof it can facilitate a wider overhang which is ideal for storage. The side of the panel that has a slightly flat side is to place on the roof. Place the rib inside closure inside the groove both overhangs will have this. The lower end is done the same way a skillion or shed roof is.
The roof rafters provide integral structural support to the roof. Place the starting panel onto one edge of the roof. A lean to roof also called a shed roof slopes in one direction with rafters that rest against another structure at their high end and overhang support posts or an exterior wall at their low end. 10 x24 lean to roof plan.
Anchor a ledger to a masonry wall with expanding anchor bolts begin by marking a line across the wall for the ledger s top edge. Notch a birdsmouth where it sits on the low wall and extend it past the wall for the eaves. The other side is for overlapping the panel. Before you cut your boards you ll need to measure the width of your building and calculate the exact length of each rafter.
If you re framing a gable roof on a new house or building a shed or even a doghouse with a gable roof you ll need to cut a number of roof rafters. An overhang to protect the shed user on a rainy night could be relatively small whereas an overhang to provide a shaded area in front of the shed to keep the interior of the shed cool will be much larger. Plan ahead and build the roof to the size of the metal panel. Alwyas confirm with your local engineer or building.
Whether you build your own trusses or order them from the lumberyard building a roof with trusses is much easier than framing a roof one rafter at a time. As a general rule when learning how to build a shed roof you ll need one truss every 2 ft. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall. With a flat shed roof the roof simply extends past the wall plate to provide an overhang.
