How to Build a Sloped-Door Awning

Measure the area above the door from one side to the other on the home's exterior. This is where you will install the awning. Create a mark with a pencil at both points indicating where the awning will start and stop. Add 2 to 4 inches to the measurement.

Cut heavy-duty canvas according to the width and length measurements with a pair of sharp fabric shears. Lay the cut canvas out flat and fold the edges in toward the center by the 2 to 4 inches more that you measured. Secure the edges -- which will be the hem -- with pins to keep them in place. Sew the folded edges with a sewing machine and thread. Remove the pins.

Create two pilot holes, with a power drill, on the exterior of the house siding -- one on each side of the door -- that correspond with the marks previously created. Screw a screw hook into the holes manually while applying light pressure to push the screw into the house siding.

Punch a grommet into the four corners of the heavy-duty canvas. Use a grommet setter for easier installation of the grommets.

Slip the two grommets located on the side of the canvas that will rest against the siding over the corresponding screw hooks.

Dig two holes out from the door that correspond with how far the awning will protrude from the door. One hole must go on either side of the door. For easier application, use a post hole digger.

Affix a screw hook to the top of two fence posts that are a few inches shorter than the height of the awning. Using slightly shorter support poles will create the slope in the awning.

Set one pole in the middle of one of the holes you dug. Keep the screw hook pointed up and fill in the hole around the pole with gravel or cement. Repeat this process for the second pole.

Stretch the fabric outward toward the support poles. Slip the two free grommets over the corresponding screw hooks at the top of the poles.
