Lets build a simple shed roof. You’ve got snow and rain are in the forecast. The Gable style roof will best protect all your structure and possessions. It has a simple construction of horizontal and vertical beams, with two sloping sides that meet in the middle. The Gable is among the easiest roof to build and one of the most common. You just need to learn how to build a gable shed roof. Well, Lets get to it.
Step 1 – Top Beams
You need four stable beams that should be placed on the top of the shed. Lets assume your shed walls are about 2-3 inches thick, your beams will need to be 4 inches thick. You need to use bolts or nails with glue to attach the beams to the top of your shed. The beams must be very stable.
Step 2 – Vertical and Horizontal Beams
In the middle of the frontal horizontal beam attach a vertical one, perpendicular to it. Repeat this on the rear horizontal beam. On the top of the front and rear vertical beams you will attach a horizontal beam that connects the two verticals.
Step 3 – Rafters
Attach diagonal rafters. The rafters will support the plywood or whatever you decide to use for coverage. Each rafter should have a diagonally cut stopper at the bottom. The stopper will rest on your top beam and ensure maximum stability. It is important to attach the rafters carefully and form strong triangles. Make sure there is a rafter on each side exactly in front of the opposite.
Step 4 – Cover
Cover the roof by attaching thick pieces of plywood or sheet iron. As an extra measure of weatherproofing and water tightness, you can also caulk between the seams of the roofing boards. This is recommended, but not required.
Step 5 – Paper
Lay down the roofing paper. The paper comes in rolls. Simply start at one corner and roll the paper from one edge to the other. Leave about 1/4-inch of paper overhanging the ends. Cut the paper and secure it. A heavy duty staple gun will do the trick. Repeat this for each strip. Be sure to overlap the paper by about an inch.
Step 6 – Shingles
Starting at the lower edge of the roof, start laying your shingles. The edge of the shingles with gaps will face the edge of the roof. Be sure that your first row of shingles overhang the roof by 1/4-inch to 1/2-inch. On the upper edge of each shingle, use roofing nails to attach it as you lay it. After you’ve completed the first row overlap it enough with the second row so that the appearance is uniform. Repeat with each additional row till you get to the top then do the same on the other side.
Cap the top ridge of the roof with overlapping shingles. Start at one end of the ridge with a single shingle, laid at an angle of 90 degrees to the run of shingles you’ve just completed. Nail it down then add another shingle, overlapping by one to two inches
