Shed roof felt is a type of black paper that contains asphalt. The roofing felt comes in a roll and is installed on the roof under the shingles to protect the roof decking.

Step 1 – Safety

When working on a roof, be sure you either have someone working with you or that someone is aware that you are working in that location. Put on your protective eye wear, work gloves and work boots. Be sure you take all of the tools you will need up onto the rooftop with you. Unnecessary trips up and down the ladder will take up more time and could lead to an accident.

Step 2 - Preparing the Roof Decking

Position your ladder against the roof of your shed. The ladder should be near to one of the sides of the shed, either the left side or the right side. The decking on the roof will need to be clean before the roofing felt can be installed. Inspect the decking and remove any debris. Any decking with damage will need to be replaced. Run a flat shovel over the decking to check for and remove any leftover nails that may be sticking out.

Step 3 – Marking the Roofing Felt Lines

Snap a chalk line on the decking. The line should be located thirty-three and five eighths above the line of the eave. Continue to snap chalk lines up the roof, every thirty-four inches.

Step 4 – Laying the First Line of Roofing Felt

Take the roll of roofing felt up onto the roof. Begin installing the roofing felt at the edge of the eave. Tack the felt paper in the center to hold it in place. Unroll the paper about five feet along the edge of the roof. Move the ladder down the side of the shed. Continue unrolling the paper until you have let out about ten feet of felt paper. Pull on the paper so that it is laying tightly along the roof. Be sure you place the paper so that you have a three eighths inch of overhang. At the edge of the roof, fold the paper around it to make a crease. Tack another nail into the end of the paper to hold it in place. Staple the roofing felt paper into place every three inches. The staples should be placed at the lower end of the felt paper.

Step 5 – Installing the Remaining Felt

Continue positioning and stapling the paper up the roof. Run the paper in opposite directions as you come to the next layer. Stop at the ridge of the roof. When you are positioning the paper, ends that meet should be overlapped by about three inches.

Step 6 – Fitting the Roofing Felt

You may need to install the roofing felt paper around circular objects on the roof. If that is the case, use the utility knife to make slits in the paper to fit around the items.
