Garden shed roof plans

This step by step diy woodworking project is about how to build a roof for a 4×8 garden shed. If you want to learn how to build a gable roof for a small garden shed, we recommend you to pay attention to the instructions described in the article and to check out the related projects. There are many shed projects featured on our site, so don’t be afraid to browse through the rest of the woodworking plans.

In most of the cases, a building permit is required so make sure you go to the town hall and ask information about the legal requirements you have to comply with. In this manner, you will also find out useful details about your shed construction. When building the shed, you should make sure the plans are detailed and come with step by step instructions, as well as with a complete list of the materials.

It is essential to invest in high quality materials, that are also water-resistant, such as pressure-treated lumber. Cut the components at the right size by using a circular saw and smooth the cut edges with a sand block. Don’t forget to ask a skilled friend to assist you during the project, especially if you don’t have a large expertise in the field. You need someone to hold the components into place, while you drive the screws in. See all my Premium Plans in the Shop.

Building a garden shed roof

Fitting the top ridge

First and foremost, you need to build the top ridge for the shed. As you can easily notice in the diagram, build the supports out of 2×4 lumber and the top ridge out of 2×6 lumber. Drill pilot holes and secure the supports to the plates by using 2 1/2″ screws. Secure the top ridge with galvanized screws and make sure it is level .

Building the rafters

Next, build the rafters out of 2×4 lumber. Mark the cut lines on the slats and get the job done by using a circular saw. Take accurate measurements otherwise the rafters won’t fit into place. Cut out the notch in the rafters as described in the diagram. Make the 60 degree angle cut to one end of the rafter before fitting them into place.

Fitting the rafters

Next, attach the rafters to the top ridge, as described in the diagram. It is essential to place the rafters equally-spaced, otherwise the structure won’t support the weight of the roof properly. Drill pilot holes through the rafters and insert 2 1/2″ screws into the top ridge and into the top plates.

Building the gable ends

Build the gable ends for the shed out of siding. Use a circular saw to make the cuts and smooth the edges with sandpaper. Fit the gable ends to the front and to the back of the shed, as you can see in the diagram. Secure the sheets to the structure, as described in the diagram. Leave no gaps between the components and secure the sheets to the frame using finishing nails.

Building the overhangs

Building the overhangs is the next step of the woodworking project. Build the rafters and the blockings out of 2×4 lumber. Lock them together using 2 1/2″ screws and leave no gaps between them. Adjust the size of the blocking to suit your needs and tastes.

Fitting the overhangs

Attach the overhangs to the front and to the back of the shed, as described in the diagram. Check if the edges are flush, otherwise the ends result won’t raise up to your expectations.

Fitting the rafter trims

Fit the 1×4 trims to the ends of the rafters, as described in the diagram. Use brad nails to secure the trims into place properly. Work with attention and make sure the edges are flush one with another.

Fitting the roofing sheets

Next, attach the 3/4″ plywood sheets to the roof of the shed, as described in the diagram. Align the sheets with great care and secure them into place using finishing nails and waterproof glue. Leave no gaps between the sheets before inserting the finishing nails.

Attaching the roofing

Cover the roofing sheets with tar paper. Install the tar paper starting with the bottom of the roof and make sure the strips overlap for at least 2″. In addition, fit a 12” strip over the top ridge. Install the shingles starting with the left- bottom of the roof, after fitting the starting course. Use roofing tacks to secure the shingles into place.

Building the shed door

Build the door for the shed out of siding and using 1×4 trims. Cut the components at the right size and secure them together by using 1 1/4″ screws and waterproof glue. Leave no gaps between the components and make sure the corners are square.

Fit the door jambs

In order to secure the door into place, we recommend you to fit appropriate 1×4 jambs to the front wall, as described in the diagram. Cut the components at the tight size and secure them to the siding by using finishing nails and waterproof glue. Fit the door top the opening and secure it to the jambs by using hinges and a door latch. Work with attention for a professional result.

Last but not least, we recommend you to take care of the finishing touches. Fill the holes with wood filler and let it to dry out for several hours. Build a shed ramp if you want to have a proper access to the small garden shed.
