Generator Shed Roof Plans

This step by step woodworking project is about generator shed roof plans. This is PART 2 of the project where I show you how to build the roof and the front double doors. This will ensure a super easy access to the interior of the shed. My plans come with step by step instructions and you can easily adjust all the dimensions to suit your needs. See my other DIY projects HERE.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting. See all my Premium Plans in the Shop.

Building a generator shed roof

Front Wall – Siding

Attach T1-11 siding to the front face of the generator shed. Make the cuts to the sheets and secure them into place with 2″ brad nails.

Building the rafters

Build the rafters from 2×4 lumber. Mark the cut lines on the rafters and get the job done with a circular saw. Smooth the edges flush for a professional result.

Building the roof frame

Attach the rafters to the top of the generator shed, as shown in the diagram. In addition, you need to fit the supports so you reinforce the structure. Drill pilot holes and insert 3 1/2″ screws to lock everything together tightly.

Side Wall – Siding

Cut the T1-11 siding panels to the right dimensions and shapes and then secure them into place with 2″ brad nails.

Back Wall – Siding

Attach the T1-11 siding panels to the back of the shed. Leave no gaps between the panels for a neat result.

Side roof trims

Fit 2×4 trims to the sides of the roof. These trims will work as overhangs, so you protect the walls from water damage. Use 2″ brad nails to secure the trims into place.

Roof trims

Attach 1×4 trims to the front and back of the generator shed roof.

Roof Frame

Build the frame for the hinged roof from 2×2 lumber. Drill pilot holes and insert 2 1/2″ screws to assemble the frame tightly. Check if the corners are square and add glue to the joints.

Fitting the roof

Attach the roof frame to the top of the generator shed and secure it to the back with hinges. Fit 3/4″ plywood panels to the lid frame and secure it into place with 1 5/8″ screws.

Front corner trims

Fit 1×4 trims to the front corners of the generator shed, using 2″ brad nails.

Corner back trims

Fit the trims to the back corners of the generator shed, as well.

Fitting the jambs

Fit 1×4 slats around the door opening, as jambs. Drill pilot holes and secure them into place with 2 1/2″ screws.

Building the doors

Build the doors for the generator shed from 1×4 lumber and the panels from T1-11 siding. Use glue and 1 1/4″ brad nails to secure the trims into place tightly.

Fitting the front doors

Fit the doors to the opening and secure them to the jambs with hinges. Install a door latch so you lock the doors tightly.

Fitting the roofing

You could fit asphalt shingles to protect the shed, as it is a straight forward solution. Therefore, install roofing felt over the roofing sheets, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under. Place a starting course at the bottom of the roof, before installing the asphalt shingles. Always read the manufacturing instructions before starting the installation, as there are several aspects that differ.

Smart Tip: The first course should star with a 3 tab shingle, the second course with a  2 1/2 tab , the third course with a 2 tab, the forth course with a 1 1/2 tab, the fifth course with a 1 tab, the sixth course with a 1/2 tab. Repeat the process from the beginning, starting with the seventh course. Don’t forget that the shingles should overhang from the drip edge about a 1/4″. In addition, secure the asphalt shingles to the roof decking with tacks.

Portable generator enclosure plans

Fill the holes with wood putty and smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain over the components to enhance the look of the shed and to protect them from decay.

Last but not least, we recommend you to take care of the finishing touches. In order to get a professional result, fill the holes and the gaps with wood filler and let it dry out for a few hours. Take a look over PART 1 of the project, so you learn how to build the frame of the shed.
