The felt should be pulled tightly over the shed construction but not too tight as this will cause it to tear. When applying the felt roof covering, ensure it overhangs the tool shed roof by about two inches as this will encourage rainwater drainage. Do not bond it to the rafters as this will allow the tool shed to move without damaging the roof. However, if felt is being used as the roof covering then use a lightweight membrane such as polythene and ensure that it slightly overhangs the roof surface. Step 4 - MembranesĪ tool shed does not necessarily require the application of a protective membrane under the roof. Ideally, they should reach from the center of one rafter to the next. For instance, if the rafters are eight inches in width and are spaced eight inches apart then the fascia boards will need to be 16 inches wide. Measuring along with the top plate of the length of your shed wall, start 1.75 from the front of your shed and work your way along the wall in 24 increments, marking each position as you go.

Step 3 - Fasciasįix fascia boards to the rafters, the boards will need to be the same length as the rafters and should be the width of the rafters plus the space distance. Secure the rafters into place and make sure that they are evenly spaced out. Use a framing square to mark out where notches will need to be and cut into the rafters with a hacksaw to ensure they fit snugly into the walls of the shed construction. For instance, if the length of the roof is 8ft then the rafters will need to be 10ft long. The rafters should be a foot longer than the total length of the building at each end of the tool shed. Insert rafters into place before applying the roof.
